Zend_File_Transfer_Adapter_Abstract bug when file not uploaded

I'm not sure where goes wrong, but some how if a file element does not contain file,
the check returns empty.
there is a bug open since may, but yet no patch for it.

file effected is
Zend_File_Transfer_Adapter_Abstract
line #617: public function isValid($files = null)

http://framework.zend.com/issues/browse/ZF-12189

Zend framework 2 FormRow Render element with ID differently

Not sure what goes up with their development team that there render element with id attribute differently, compared to those without it.
Took me sometime to figure this, sigh*!

And guess what, i cant file a zend framework 2 bug.. lol
Only Zend Framework 1 jira tracker is available, not sure if ive visited the wrong link

Zend AbstractTableGateway does not support table alias

Couldnt figure out how to do it,
finally, i created my own Sql and and Select on my own.

But ive to overwrite executeSelect to allow table select with alias
$resultSet = $this->selectWith($oSelect);

Zend framework 2 route example

router' => array(
    'routes' => array(
      'bannermgt' => array(
        'type' => 'segment',
        'options' => array(
          'route' => '/bannermgt[/:action][/:id][/page/:page][/searchname/:searchname][/searchpath:searchpath][/]',
          'constraints' => array(
            'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
            'id' => '[0-9]+',
            'page' => '[0-9]+',
            'searchname' => '[^/]*',
            'searchpath' => '[^/]*',
          ),
          'defaults' => array(
            'controller' => 'BannerMgt',
            'action' => 'index',
            "page" => 1,
            "searchname" => "",
            "searchpath" => ""
          ),
        ),
      ),
    ),
  ),

Take note that ordering of URL in route is strict.
Therefore searchname must come first before searchpath.

Or else , you may ommit:
[/searchname/:searchname][/searchpath:searchpath]
And append as querystring
/bannermgt/list?searchpath=xxx&searchname=yyy

Zend Framework 2 redirect and forward

Both uses different path name to identify.
Redirect uses physical url on browser side, therefore the route name is to be used.

For forward wise, its using the factory service name to identify the controller to run.
example:
config:

'controllers' => array(
        'invokables' => array(
            'Application\Controller\Index' => 'Application\Controller\IndexController',
            'Application\Controller\Login' => 'Application\Controller\LoginController'
        ),
    ),


'router' => array(
        'routes' => array(
            "login" => array(
                'type' => 'segment',
                'options' => array(
                    'route' => '/login[/:action][/]',
                    'constraints' => array(
                        'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                    ),
                    'defaults' => array(
                        'controller' => 'Application\Controller\Login',
                        'action' => 'index',
                    ),
                ),
            ),



$this->forward()->dispatch("Application\Controller\Index", array("action" => "someaction");

for redirect:
$this->redirect()->toRoute("login", array("action" => "someaction");

to get current controller name:
$this->getEvent()->getRouteMatch()->getParam("controller");

to get current route name:
return $this->getEvent()->getRouteMatch()->getMatchedRouteName();

Zend framework 2 get other view helper instance

in view:

$oFormat = $this->plugin("dateFormat");
$oFormat->setLocale("en_GB");
echo $oFormat->__invoke(...);

to invoke directly:
echo $this->dateFormat(...);

Zend framework 2 Locale / i18n

In Application/config/module.config.php:

return array(
//...,
'translator' => array(
        'locale' => 'en_GB',
        'translation_file_patterns' => array(
            array(
                'type'     => 'gettext',
                'base_dir' => __DIR__ . '/../language',
                'pattern'  => '%s.mo',
            ),
        ),
    ),
//...


In Application/Module.php bootstrap:

//set your time zone here

date_default_timezone_set("Asia/Kuala_Lumpur");
$oViewHelperManager = $e->getApplication()->getServiceManager()->get("ViewHelperManager");
$oViewHelperManager->get("dateFormat")>setLocale($sLocale)->setTimezone(date_default_timezone_get());
$oViewHelperManager->get("numberFormat")->setLocale($sLocale);
$oViewHelperManager->get("currencyFormat")->setLocale($sLocale)->setCurrencyCode("MYR");

To output in view template:
echo $this->translate("My text here");
echo $this->dateFormat(new DateTime(), IntlDateFormatter::SHORT);
echo $this->numberFormat(12345.0123, NumberFormatter::DECIMAL);
//default currency
echo $this->numberFormat(12345.5226, NumberFormatter::CURRENCY);

//custom currency output:
echo $this->currencyFormat(1234.5226, "MYR");


Requires:

• php5-intl

Active directory login from Zend

After spending hours solving this issue,
and ive found that each different company have different active directory path setting.

For login purpose, the main concern are the baseDn.
Some uses this:
CN=Users,DC=EXAMPLE,DC=COM

Some uses this:
OU=Users,DC=EXAMPLE,DC=COM

And event this:
OU=Users,OU=.User Accounts,DC=EXAMPLE,DC=COM

Example of Zend 1 config in yaml:

ldap:
    server1:
      host: EXAMPLE.LOCAL
      accountDomainName: EXAMPLE.LOCAL
      accountDomainNameShort: EXAMPLE
      baseDn: OU=Users,OU=.User Accounts,DC=EXAMPLE,DC=LOCAL
      bindRequiresDn: false

Zend Framework 2 controller init

Example:

class MyController extends Controller {
protected $bInit = false;


public function onDispatch(\Zend\Mvc\MvcEvent $e) {
    if (! $this-> bInit) {
      $this->init();
      $this-> bInit = true;
    }
    return parent::onDispatch($e);
  }

Zend Framework 2 file upload

Example:
Note: Remember to set destination and filter to adaptor before running isValid or Receive,
Because setting filter or destination after running isvalid will cause the isvalid to add 2 times check on the file, one as tmp_name and another as destination name..
which will cause Count validator to fail!


    $sDestination .= getcwd() . "/public/assets";
 
    if (!is_dir($sDestination)) {
      if (!@mkdir($sDestination, 0777, true)) {
        throw new \Exception("Unable to create destination: " . $sDestination);
      }
    }
    $size = new Size(array('min' => 10, "max" => 10000000)); //minimum bytes filesize
    $count = new Count(array("min" => 0, "max" => 1));
    $extension = new Extension(array("extension" => array("jpg", "png", "swf")));

    $oFile = $this->params()->fromFiles('txtFile1');
 
    $adapter = new \Zend\File\Transfer\Adapter\Http();
    $adapter->setValidators(array($size, $count, $extension), $oFile['name']);
    $adapter->setDestination($sDestination);
 
    if (! $adapter->isValid()) {
      $dataError = $adapter->getMessages();
      $error = array();
      foreach ($dataError as $key => $row) {
        $error[] = $row;
      }
      $form->setMessages(array('txtFile1' => $error));
    } else {
   
      if ($adapter->receive($oFile['name'])) {
        $form->get("txtFile1")->setValue($adapter->getFileName());
      } else {
        $form->setMessages(array('txtFile1' => "Receive failed"));
      }
    }

Zend framework 2 and firebug and composer

Kloxo dns template error

Ive came accross some long error on kloxo dns template,
and it turn out to be corrupted dns template.
I only realize this on creation of a domain or addition of a client.

running /script/fixdns seems to fix this issue,

if you have created a domain or client, just delete the client,
and recreate again.

yes, its still annoying that kloxo always have update issue which corrupt some of the files,
most obvious was roundcube update

Zend file upload and addfilter rename isnt working

Ive had spent many days repeatly on different project, stumbling on one same issue.
AddFilter rename isnt working on my file upload.

It was one simple solution,
first, never ever getValue from the field before addfilter rename is in place.

Its very easy that we miss out lines of code where by it tries to populate data model from form.
Also its also easy to accidentally getting value from model to replace upload form field.

Make sure addfilter rename is called before isvalid is checked.

Hope this will solve your hair pulling days figuring why it isnt working.
The worst part is, Zend Framework isnt complaining about it!

modx setup blank page

After some research,
blank page could be caused by insufficient memory,
set php memory limit to higher

another possible issue is core/config/config.inc.php

it turn out , on my machine when i was migrating a remote modx to my local machine,
the write process onto config.inc.php somehow halted with some unknown error which caused blank page.
So, the page was a template file, and it turn out to be an invalid php script file.
ive to redownload my config.inc.php and try rerun..

But some how in the end, the final setup failed half way, with no errors again, content got loaded half way with no errors.

Yes, in the end, i applied the latest upgrade files onto the root,
and rerun setup,
but this time, it went well and it was a successful upgraded and the site is working!

a better looking checkbox for zend form element checkbox

Code:

$this->getElement('iagree')->addDecorator('Label', array('placement' => 'APPEND', 'class' => 'checkbox', "escape" => false));
//escape to false to prevent from escaping link within the label
//also adding checkbox class to the dd tag and label tag
// and place label to the right of checkbox

Css wise:

  margin-left: 175px;
  float: left;
}

dl label.checkbox {
  display: block;
  margin-left: 190px;
  width: auto;

jquery form and tinymce

Jquery form doesnt work properly with tinymce,
one way work around is to trigger tinymce input saving before submitting the form


jQuery("#youformid").ajaxForm({
    beforeSerialize: function($form, options) {
      tinyMCE.triggerSave();
    }
});

tinymce mceRemoveControl NS_ERROR_UNEXPECTED: Component returned failure code

Im not sure if its considered a bug, but this is annoying for me.
When i ran mceRemoveControl command to remove a already destroyed tinymce on a textarea,
i get NS_ERROR_UNEXPECTED.

After googling around with not much result, ive decided to dig into the source code ,
and finally found a solution.
Instead of calling directly mceRemoveControl, call this tinyMCE.remove(tinyMCE.getInstanceById()):

var oInstance = tinyMCE.getInstanceById("txtContent");
if (oInstance) {
  if (oInstance.isHidden()) tinyMCE.remove(oInstance);
  tinyMCE.execCommand('mceRemoveControl', true, "txtContent");
}
tinyMCE.execCommand('mceAddControl', true, "txtContent");

tinyMCE.remove(tinyMCE.getInstanceById("txtContent"))

tinyMCE.remove(tinyMCE.getInstanceById("txtContent"))

spam.dnsbl.sorbs.net and dnsbl.anticaptcha.net should be banned from spam filtering!

These two black list provider seems to ask for money to get de-listed from from their server.
Their so called "fine" doesn't seems to be appropriate when there are so many clients machine which may have faced infection from virus or malware.
The real fine should be done to the actual virus creator or malware!

csf and kloxo

Running server without some kind of protection, open up to bruteforce and dos attack.
Even with ssh port set to different port, or PermitRootLogin no, isnt good enough.

People can still guess a domain username based on the control panel being used,
especially plesk and cpanel.
Once they fire up their brute force attack, they can use it to attempt to get your clients password.

So its best to install some kind of detection and auto blocking system to prevent this from happening.
CSF is one of the best tool to use.

Once installed, here are some useful tips you might want to consider:

enable UI, but remember to set the username and password in the ui section below the ui enable line.
Email alert to yourself, incase if someone is attacking your server.

And on top of that, for kloxo purpose, you may want to ignore this list of processes, by adding these lines:

exe:/usr/local/lxlabs/ext/lxlighttpd/sbin/kloxo.httpd
exe:/usr/libexec/mysqld
exe:/usr/sbin/httpd
exe:/usr/bin/httpd
exe:/var/qmail/bin/qmail-clean
exe:/var/qmail/bin/qmail-send
exe:/usr/bin/freshclam
exe:/var/qmail/bin/qmail-rspawn
exe:/var/qmail/bin/splogger
exe:/usr/sbin/clamd


into /etc/csf/csf.pignore

Option options may be useful is set TESTING to 0.

/etc/csf/csf.conf
add in port 7777 to
TCP_IN

After thats done,
run this:
/etc/init.d/csf start
/etc/init.d/lfd start

For directadmin wise:
add these lines into /etc/csf/csf.pignore

exe:/usr/local/bin/freshclam
exe:/usr/libexec/openssh/sftp-server


to whitelist:
add ip into:
/etc/csf/csf.allow

Other optional setting:

To set connection limit per ports:
CONNLIMIT = "22;5,80;10,110;5,25;5,587;5,21;5"
example above:
port 22: max 5 per ip,...

jquery fullcalendar reload events data

jQuery("#targetdiv").fullCalendar("refetchEvents");
jQuery('#targetdiv').fullCalendar("rerenderEvents");

This might be useful to others:

        center: 'title',
        right: 'month,agendaWeek'
      },

Zend_Form_Element_File setFilter rename and form->getValues() not working

Take note that form->getValues() will return all values from form, including calling
form file element to receive().
Therefore, setFilter rename shall be called before form->getValues line.

jQuery Form IFrame

When jQuery.form iframe option is assigned to true,
the result of the iframe will be triggered twice if the result contains javascript.

The solution to the problem is to assign [textarea] tag to wrap up the contain.
But having tags within the textarea tag will cause some unexpected result on the contain.
Therefore, php htmlentities shall fix the issue for the tags within the content.

If you are running on Zend, there will be issue.
By default, you may disable the layout and display the action view template.
But due to requirement to wrap the output with textarea,
we shall need to disable the view template, and do a manual output of the view file.

Solution (in controller):
$this->_helper->layout->disableLayout();
$this->_helper->viewRenderer->setNoRender(true);

$sView = $this->getViewScript();

if ($this->getRequest()->isPost()) {
   return "[textarea]" . htmlentities($this->view->render($sView)) . "[/textarea]";
} else {
   return $this->view->render($sView);
}


This solution shall output a normal view if its not submitted from the form.

jQuery form and Zend_Form File

It appears that Zend Form will validate fail if we are using ajax or jquery form to submit the form.
To fix the issue, just ensure the form is submitted with the parameter: iframe: true

Also note that IE 8 or below will behave strangely when submitting via jQuery Form with file input.
So avoid using it on IE8 or below...

clear both whitespace

Its common to use clear:both style to push the parent container box to fit the height nicely.
It recent finding, realized when ever there is a float div above it, it will cause a huge white space to the container.
One way to fix it is to set the parent container: overflow: hidden

Kloxo Roundcube unable to save to address book

Just faced this issue back 1 week ago, v 6.1.22 seems to face this issue on roundcube email.
upon further investigation into /var/log/httpd/error_log, found this:


PHP Notice:  MDB2 Error: no such field Query: _doQuery: [Error message: Could not execute statement] [Last executed query: INSERT INTO contacts (user_id, changed, del, `vcard`, `name`, `email`, `words`) VALUES (1, now(), 0, 'BEGIN:VCARD\\r\\nVERSION:3.0\\r\\nFN:[name]\\r\\nEMAIL;type=INTERNET:name@example.com\\r\\nEND:VCARD', 'name', 'name@example.com', ' name@example.com name')] [Native code: 1054] [Native message: Unknown column 'words' in 'field list']  in /home/kloxo/httpd/webmail/roundcube/program/include/main.inc on line 2270, referer: ...

So, i went to dig into
/home/kloxo/httpd/webmail/roundcube/update/SQL/mysql.update.sql

And found these line which add the "word" column into the contacts table.

So i went to login as admin user into the kloxo and server > localhost > phpmyadmin,
and ran these script for roundcubemail database:

ALTER TABLE `contacts` ADD `words` TEXT NULL AFTER `vcard`;
ALTER TABLE `contacts` CHANGE `vcard` `vcard` LONGTEXT /*!40101 CHARACTER SET utf8 */ NULL DEFAULT NULL;
ALTER TABLE `contactgroupmembers` ADD INDEX `contactgroupmembers_contact_index` (`contact_id`);

And now it works perfectly.
Please take note not to run the entire file. You might likely to hit already ran sql syntax, and might took the risk to clear of your tables, especially message table.

MySQL lock table and subqueries

MySQL complaints when a subqueries table / alias is not locked.
But Even if we lock the table by tablename, it will still complaint on the subquery table being not locked.

Example:

select n.node_id,
    (select count(*) from node where node_aboveid=n.node_nextleftnodeid) as leftnextcnt,
    (select count(*) from node where node_aboveid=n.node_nextrightnodeid) as rightnextcnt,
    n.node_nextleftnodeid, n.node_nextleftdepth from
    node n

To solve this issue,
Every sub select table must have a alias name, different from the main table name.
Example:


select n.node_id,
    (select count(*) from node nleft where node_aboveid=n.node_nextleftnodeid) as leftnextcnt,
    (select count(*) from node nright where node_aboveid=n.node_nextrightnodeid) as rightnextcnt,
    n.node_nextleftnodeid, n.node_nextleftdepth from
    node n

And makesure to lock tables node write, node n write, node nleft write, node nright write;

Magento deleting an order

It have been some argument about able to cancel or delete a processed or shipped or completed order.
But by end of the day, there are reasons that people want to delete the order.
Be it by mistake, or due to testing the order.

I finally found a extension which works with magento 1.6.2, but it does not cover properly for 1.6.2.
http://www.magentocommerce.com/magento-connect/seamless-delete-order.html

So i ended up altering the module block to support it.
http://www.mercstudio.net/assets/files/EM_DeleteOrder-1.0.5.tar.gz


But due to the nature of the reporting in magento, its not possible to delete the cached reports in the database using this extension.
It can only be deleted based on date, but becareful with this procedures.
The reporting tables for sales order are:
sales_order_aggregated_created
sales_invoiced_aggregated_order
sales_refunded_aggregated
sales_refunded_aggregated_order
sales_shipping_aggregated

Please note that i do not responsible for any data lost in the extension. So do the original developer himself. Please remember to backup your database in system > tools > backup before applying this extension and deleting any order.

infinite loop in bootstrap module

It seems that if you want to develop a bootstrap for module,
you will need to extends Zend_Application_Module_Bootstrap

But how to get Layout from bootstrap_bootstrap?
$this->getApplication()->getResource("layout");

How to get view?
$this->getApplication()->getResource("layout")->getView();

What if i get undefined getView of a undefined object?
Yes, this problem is because layout and view bootstrap is not loaded in Zend_Application_Bootstrap_Bootstrap.

Makesure to run these in the class which extends bootstrap_bootstrap:
$this->bootstrap("View");
$this->bootstrap("layout");

The problem is caused by inode watch limit. I suspect its due to the dropbox that ive installed.

To fix it, set fs.inotify.max_user_watches configuration to higher:
sudo sysctl -w fs.inotify.max_user_watches=16384

Zend DB Select join

Example of joining table using dbtable (EntStudio_Db_Table_Abstract)

$maintable = "x";

$query = $dbtable->select();
$query->setIntegrityCheck(false);
$query->from($dbtable, array("*")); //only specify column for main table

   
$query->join(array("u" => "table2"),  $maintable . ".userid=u.id", array("username")); //only specify column for table2

to output to test:
echo $query;

to get results:

$resultSet = $dbtable->fetchAll($query);
$entries   = array();
foreach ($resultSet as $row) {
//... codes here
}


to get a single row:
$row = $dbtable->fetchRow($query);

Zend Notification

Zend built in notification are divided into session saved message, and current message.
$flashmsg = Zend_Controller_Action_HelperBroker::getStaticHelper('FlashMessenger');

To get last added message in previous request (which is saved in the session):
$flashmsg->hasMessages();
$aMsg = $flashmsg->getMessages();

To clear the messages storage:
$flashmsg->clearMessages();
--------------------
To get current added message (same request):

$flashmsg->hasCurrentMessages();
$aMsg = $flashmsg->getCurrentMessages();

To clear the current messages storage:
$flashmsg->clearCurrentMessages();


Please note that the current and the session message are separated, and need to be called respectively to retrieve all messages in the notification

zend view render vs layout render

To render another view file within the same controller,
$view / $this->render("filename.phtml");

to render a view file within layout:
$view / $this->layout()->render("filename"); //without .phtml

jquery(document).ready not running

Latest jQuery seems to halt all event execution when it comes to error.
If one of the javascript contains error, other event will not be triggering.
Its one of the gotcha that i stumbled upon since jQuery 1.6

Magento base system principle

Blocks

Block updates is set in config.xml
config > layout > updates > [modulename] > file
#files tag will point to a layout xml file in app/design/frontend/[themename]/layout/[modulename].xml

in [modulename].xml contains:
layout > [modulename] > [controllername] > [actionname] > reference [name=content] > block

block attributes available are:

type: To base this block on a class in your module. naming is case sensitive

@format: [Modulename]/[Block name]

@example: type="ProductLister/Lister" points to app/code/local/[namespace]/[Modulename]/Block/[Block name].php, with class name: [namespace]_[Modulename]_Block_[Block name]

name: a name which can be retrieved by calling $this->getChild('name') or $controller->getLayout()->getBlock("name")
template: points to the actual path of the phtml template file
@location: app/design/frontend/[themename]/template/[path]

jquery height() or width() gotcha!

When a jQuery(target).height() is called in jQuery.ready event,
will return the height of the target, excluding the size of the image inside.
the only way to do it properly is to wait for the images to be loaded, therefore,
replacing it with jQuery(window).load(...) works best :)

jquery 1.7.2 bug?

I've a dom which is set to position: relative, style.left to 0

console.log($(target)); //return array of 1 object

$(target).css("left", "100px");
console.log(dom.style.left); //seems to return 100px, which is correct

but when i run
$(target).css("left"); // return 110px

Updates:
$(target).position() - returns position from parent offset
$(target).offset() - returns position from the screen

Example:

The only work around method i could think of is to directly set:

position: relative;

top: 0;

left: 0;

Or

jQuery(target).offset(jQuery.target.offset());

Then use dom.style.left or dom.style.top directly.

Please note that this is tested on linux chromium browser 18.

javascript || operator gotcha

the OR operator of javascript might not execute the entire condition to complete it.
If it detected that the earlier condition meet, it will automatically abardon the check.

Example:
var x = true;
x = x || runmyfunction();

if x is true, runmyfunction will not be checked or executed. But if x is false, then runmyfunction will be executed to return the value.

installing apc on kloxo

For Yum based OS:
sudo yum install pcre-devel
sudo pecl install apc

Then create /etc/php.d/apc.ini

Magento Order status does not convert to Processing

Tinkering around to make a payment gateway integration for iPay88 took me some really significant time.

I've been using some method from paypal module to redirect the form to ipay88,

and does a re-query to ipay88 server to determine the approve of transaction from ipay88.

On done, created an invoice and saved the transaction for the invoice.

Payment paid appears correctly, but some how order status still remain "pending".

I realized that i did not set the cctransid to the payment in my controller, 

so one way to do it is to pass the TransId from controller to payment method model.

To do this, create a model class to accommodate values from request form passed in from ipay88,

then in payment method model capture function, retrieve the ipay88 returned model and setCcTransId(...).

When done, the order will now be shown as "processing", depending on the setting in the admin configuration for the payment status on payment.

Sample below:

//getting config saved in admin:
$aConfig = Mage::getStoreConfig("payment/Ipay88");
$merchantcode = $aConfig["merchantcode"];
$oResponse = Mage::getSingleton("Ipay88/Api_Response");
//convert data from postback of ipay88 into oResponse as object data
Varien_Object_Mapper::accumulateByMap($_REQUEST, $oResponse, array(
  "MerchantCode", "PaymentId", "RefNo", "Amount", "Currency", "TransId", "AuthCode", "Status",
  "ErrDesc", "Signature", "Remark")
);

//codes to requery ipay88 for actual transaction
//...
if ($iPayResult == "00") {
  //success
  //update order status and payment status
 if ($oOrder->canInvoice()) {
  $invoice = Mage::getModel('sales/service_order', $oOrder)->prepareInvoice();
  
  if (! $invoice->getTotalQty()) {
   Mage::throwException(Mage::helper('core')->__('Cannot create an invoice without products.'));
  }
  
  $invoice->setRequestedCaptureCase(Mage_Sales_Model_Order_Invoice::CAPTURE_ONLINE);
  $invoice->setTransactionId($cctransid);
  //below this will trigger capture in method model
  $invoice->register();
  $transactionSave = Mage::getModel('core/resource_transaction')
  ->addObject($invoice)
  ->addObject($invoice->getOrder());
  
  $transactionSave->save();
 }
}

Next, in the payment method model capture:

public function capture(Varien_Object $payment, $amount)
{
 if (!$this->canCapture()) {
  Mage::throwException($this->_getHelper()->__('Capture action is not available.'));
 }
 
 $oResponse = Mage::getSingleton("Ipay88/Api_Response");
 $payment->setCcTransId($oResponse["TransId"]);
 return $this;
}

Sample of iPay88 Model to hold request data

class MercStudio_Ipay88_Model_Api_Response extends Varien_Object {
  
}

Yes, its an empty class which extends Varien_Object :) The Magic of Varien object is that it accept any data set to it (setVariablename(value) or setData("variablename", value)), and you may retrieve the data by calling getData("variablename")

jQuery .load complete did not fire

This happen when i was dealing with an upgrade from jQuery 1.5 to 1.7.2.
It took me some struggle to find out what happened, and finally, i found the issue.
It seems that the oncomplete function will not run if the document itself somehow contains javascript with syntax error in the script. It wasn't any problem for jQuery1.5, but for jQuery 1.7.2, it seems to halt execution after loading the content to the targeted dom.

MODx Return Error 400 in manager

The recent changes on MODx seems to create a new kind of error 400 on all the javascript used in the manager screen.
The problem comes from issue with minified index.php where it over replaced manager/assets with assets path, therefore doubling the path to the actual javascript file.
The solution have been resolved in the nightly build of MODx 2.2.1.pl

Magento Export Sales Order Duplicate headers received from server

Its a bug which have been fixed in magento 1.7.
But for 1.6.2 users, you may change the core to fix this in:
app/code/core/Mage/Core/Controller/Varien/Action.php in function _prepareDownloadResponse:

By adding , true as the 3rd parameter in these lines:

->setHeader('Content-Length', is_null($contentLength) ? strlen($content) : $contentLength, true)

 ->setHeader('Content-Disposition', 'attachment; filename="'.$fileName.'"', true)

 ->setHeader('Last-Modified', date('r'), true);

modx package management could not install

After dabling around on my new server,
i realize that the package installer did not work.
Further examination reviewed the error "package could not be found".

So i went into the core/packages and found that the extraction process did not complete.
After searching around, 1 way to work around it is to set under setting,
search for "archive_with" and change it to true.

Make sure to delete the package with "force deletion" and redownload and try install again...
hope it works for you... :)

magento shipping table rates import

Magento shipping method have to be set in 2 different environment.
One on config, and another on site.
To import or export the rates, you will need to select "site" / "Default sites" to have the options to import the rates.
Before setting up these rates, you will have to ensure that you have setup the regions / states on your targeted countries to market.
Its can be set manually in database table on table:
directory_country_region.
Once you have set it, you may run this script to insert the name to the translation table for region name:
directory_country_region_name
If you are lazy like me, i will just run this SQL script below to populate the name to the directory_country_region_name table:

INSERT INTO `directory_country_region_name` (`locale`, `region_id`, `name`) 
SELECT 'en_US', `region_id` , `default_name`
FROM `directory_country_region`
WHERE country_id='ID';

You will have to make sure that the directory_country_region.code field contain a unique code for your state / region. It's a norm to use countrycode-statename to ensure it is unique for every states you setup.
Example: ID-SUMUTR
which represent indonesia: sumatera utara.
In the import CSV, this will be the format of the csv (as of magento 1.6):
Country, Region/State, Zip/Postal Code, Order Subtotal (and above), Shipping Price
Notes:
Country should contain short 2 alphabet code of the country, such as ID = Indonesia
Region/state field will be the field to contain the region/state code.
Order subtotal is optional (0)
Zip / Postal code is optional (empty)
Shipping price will be the price in shop currency.

external php calling login into magento

Magento contains its own call to session_start() when included into your php application.
To ensure that your session set is the same session as magento front end, you will need to include magento in this manner:

require_once("pathtomagento/includes/config.php");
require_once("pathtomagento/shop/app/Mage.php");


umask(0);
Mage::app();
//this is the magic call to ensure the session of front end tally with your php session

Mage::getSingleton('core/session', array('name'=>'frontend'));

To set someone as logged in:

$oCustomer = Mage::getSingleton('customer/customer')->setWebsiteId(Mage::app()->getStore()->getWebsiteId())->load(#id);


$oSession = Mage::getSingleton('customer/session');
$oSession->setCustomerAsLoggedIn($oCustomer);

Updated 2012 feb 25:
This method seems to lack of event triggering when customer is logged in.
When you login as a member A, view a product X. Then logout and view product X. Then login as member A again and view product X,
It will cause the product to be directed to an error 404.
This is due to an error in report log which caused a duplicate in table: report_viewed_product_index. Duplicate entry for UNQ_NEOSHOP_REPORT_VIEWED_PRODUCT_INDEX_CUSTOMER_ID_PRODUCT_ID (to be exact) Observer class triggered: app/code/core/Mage/Reports/Model/Event/Observer.php, method: catalogProductView

Suppose, when some logged in, it will trigger several core events, which related to "customer_login", but this does not seems to work when there is not front controller been dispatched.
One way to fix it is to run a action on the front controller and then continue with the code.
But problem is, the default module "" will trigger module cms which will display entire html of the magento cms front page.
To fix this, add your own custom controller, and a dummy action which does not echo anything.
And call magento to run this front controller by calling this way:

umask(0);
//this will enable sensitive error
//Mage::setIsDeveloperMode(true);
$oMageApp = Mage::app();
$oMageApp->getRequest()->setModuleName("yourmodulename");
$oMageApp->getRequest()->setActionName('yourmoduledummymethodname');
$oMageApp->getFrontController()->dispatch();

magento Name gotcha

It seems that all module directory name must start with capital.
Example:
app/code/local/Mynamespace/MyModule

This will fail:
app/code/local/Mynamespace/myModule

Took me some time to figure this out... :(

magento overide model customer resource customer

Took me ages to found the issue.
It turn out that if i overide xml pointing to the new class file is case sensitive and space sensitive.
This is how i've managed to override customer/model/resource/customer

 
  
   Namespace_MyModule_Model_Resource_Customer
  
 

Magento inline popup for product

Took me several days and many hours of researching,
Finally, ive made it up to the stage where i can declare glory to my objective :)
Magento uses many combination of configuration to customize to your setting.

Okay, i needed to do a popup to view product without showing a full layout product viewing page.

I didn't wanted to alter the core functionality, as i wanted both:

1. Exists magento product viewing page with full page layout
2. A "quick view" button to show just the non-layout based popup

It would be much easier if i could just override the magento product view template by just copying existing template file into my template directory, and modify it as i needed. But this will override the entire product page, so we will no longer have access to the original full layout page.
Just for your reference, here is how its done:
--------------------
copy from:
app/design/frontend/base/default/template/catalog/product/view.phtml
to:
app/design/frontend/default/default/template/catalog/product/view.phtml


other optional files which you may override, but will need to have respective directories name, similar to the base template location:
app/design/frontend/base/default/template/catalog/product/view/*


---------------------

Now, i need to customize the base layout file for all my pages, the product listing, and product viewing page.
I need both, the base layout file to use 1column.phtml, listing page to use only category.phtml layout. And the full view product page to use product.phtml layout.
---------------------
create a file:
app/design/frontend/default/default/layout/local.xml
The content of the file can be edited as show in photo below.
Please take note on the tags: catalog_category_default (listing), catalog_product_view (view), checkout_onepage_index (checkout), default (default / base layout file)

Then upload the respective files to:
app/design/frontend/default/default/layout/template/page/category.phtml
~/product.phtml
~/1column.phtml
You may copy the layout files from app/design/frontend/base/default/template/page/1column.phtml to start out with.
----------------------

Next, i wanted to remove some of the items which i dont use.
So, edit the file app/design/frontend/default/default/layout/local.xml
And add in remove tags under default tag:

---------------------------

And here comes the difficult part, the standalone popup product viewing page, which does not replace existing product viewing full layout.
To do this, we will need to write our own customized module.
You may refer here to learn from begining:
http://magento4u.wordpress.com/2009/06/08/create-new-module-helloworld-in-magento/

Okay, how are we going to allow the user to choose our layout from the CMS module?
Do this, edit:
app/code/local/[namespace]/[module]/etc/config.xml
directly under config tag, add in these tree:
config > global > page > layouts > yourpagename
Make sure to add in all the layout that you wish to be available on the CMS module, such as category.phtml and product.phtml

Once you are familiar with how to write blocks, have it configured to be installed, and integrated with custom blocks, then we can begin writing a extended version of the Catalog/product/view functionality without full layout.

inside your module path:
app/code/local/[namespace]/[module]/etc/config.xml

Create these tags:
config > frontend > layout > updates > mylayout > file > mylayout.xml (content)
global > helpers > mymodule > class > namespace_mymodule_Helper (content)
global > blocks > mymodule > rewrite > myproductview > namespace_mymodule_block_product_view (content)

Notice that the class file is declared for our custom layout "myproductview" which will be seen declared on the next file (mylayouts.xml).
We shall need helper class declared, as default product controller of magento will need a helper class to render the page.

Next, the final layout file:
app/design/frontend/default/default/layout/mylayouts.xml

Create the nodes:
layout > mymodule_product_view (as shown on the photo below)

Then,

Take note that this will also need you to create the file:
app/design/frontend/default/default/template/page/inline.phtml
The file shall content a non html or body tags, to be displayed as popup using lightbox or colorbox.

Now, create the controller file to extend magento product controller:
app/code/local/Namespace/Mymodule/controllers/ProductController.php

Next, create the helper file to extend magento product helper:
app/code/local/Namespace/Mymodule/Helper/Product/View.php

And, create the Block handler file to handle block view for product
app/code/local/Namespace/Mymodule/Blocks/Product/View.php

And finally, duplicate the file
app/design/frontend/base/default/template/catalog/product/view.phtml

to

app/design/frontend/default/default/template/mymodule/product/view.phtml

and modify this file according to your requirement :)

to access the original product page from browser:

http://pathtomagento/catalog/product/view?id=[productid]&category=[categoryid]

to access your customized popup page (standalone) from browser:

http://pathtomagento/mymodule/product/view?id=[productid]&category=[categoryid]

modx page not found after upgrade to 2.1

There is some cache issue on modx, after an upgrade from modx 2.0.x
Clearing cache does not seems to fix the issue.
One way to fix it is to edit every resources which ever are effected...


Updates:
Another way is to do a script to run recursively on all resources, edit it by changing the alias, and save,
and then changing the alias back to the actual alias, and save it again.
Example:

function doFixResource($id, $iLevel=1) {


$oRes = $modx->getObject("modResource", $id);
$aContext = array($oRes->get("context_key"));
$iParentId = $oRes->get("parent");
if (!empty($iParentId)) {
doFixResource($iParentId, $iLevel+1);
}

echo "Fixing: " . $oRes->get("id") . "(lvl:" . $iLevel . ")," . $oRes->get("alias") . "::" . $oRes->get("pagetitle") . "(" . $oRes->get("context_key") . ")
\n";
$sAlias = $oRes->get("alias");
$oRes->set("alias", $sAlias . "-". rand(10000,9999));
$oRes->save(false);
//doFlushContext($aContext);
$oRes->set("alias", $sAlias);
$oRes->save(false);
doFlushContext($aContext);

}


then run flush script:

function doFlushContext($aContext) {
global $modx;

$modx->cacheManager->refresh(array(
'db' => array(),
'auto_publish' => array('contexts' => $aContext),
'context_settings' => array('contexts' => $aContext),
'resource' => array('contexts' => $aContext),
));

}

And finally, run clear cache from manager screen.

Tips: If you want performance, cached up all the id which you have run doFixResource by using static variable, and skip it, it may save you up to more than 80% of the time :)

modx 2.2 changes

$modx->getUser("contextname")
return anonymous user if no user is logged in to the context.
when getOne("Profile") is performed on anonymous user, will return null, so some error might be thrown.

modx->db->dbfunctions is now deprecated, so use the actual function from $modx itself.
for more information, refer here:
http://rtfm.modx.com/display/revolution20/Upgrading+MODx#UpgradingMODx-VersionSpecificChanges
http://rtfm.modx.com/display/revolution20/Summary+of+Legacy+Code+Removed+in+2.1

Example of a big change:

$modx->db->query is completely different from $modx->query

So you may use parseBinding to do your query.

Example:

$sSelectSQL = "select `parent`, `context_key` , id, `alias`, pagetitle, longtitle from modx_site_content where context_key=:contextand parent=:parent and `alias`=:alias and (published=0 or deleted=1)";

$aParam = array(":context" => "web",

":parent" => 1, ":alias" => "somealias");

$sResultSelectSQL = $modx->parseBindings($sSelectSQL, $aParam);

$stmt = $modx->query($sResultSelectSQL);

if (! $stmt) throw new Exception("SQL Failed: " . $sResultSQL);

//to fetch all

$aCount = $stmt->fetchAll(PDO::FETCH_ASSOC);

foreach($aCount as $oRow) {

  echo $oRow["id"];

}

//to fetch one

$oRow = $stmt->fetch($PDO::FETCH_ASSOC);

echo $oRow["id"];

And other class based method:

//to get an object row

$oRes = $modx->getObject("modResource", array("context_key" => "web", "parent" => 1, "alias" => "somealias"));

echo $oRes->get("id");

modx 2.2 modX::isFrontEnd() is undefined?

After doing an upgrade to modx2.2, editing any resources seems to throw this error.
Solution, go to package manager, upgrade tinymce plugin.
And we are all set to go! :)

modx 2.2 upgrade from 2.0 error 500

There were seems to some configuration changes from 2.0 to 2.2 on core/config/config.inc.php.
When i was upgrading, the test database seems to response with an error 500.
After inspecting core/cache/logs/error.log, it shows "no database selected"

So i went into editing core/config/config.inc.php and found the $dbase = "{dbase}"
Using setup with advanced configuration does not seems to do the trick.
The solution now is to edit core/config/config.inc.php and set $dbase = "`mydatabasename`"
and $database_dsn = 'mysql:host=localhost;dbname=mydatabasename;charset=utf8';

Take note on the different between the 2, one with `` delimiter, and one without.
Next, rerun setup for upgrade shall do the trick :)

magento enable cookie issue on chrome and ie

I came across this problem while trying to test my localhost machine for adding a product to cart.
it turn out to be some sort of cookie session issue on magento.

changing session length nor disabling cookie checking does not seems to work.
its suppose to only happen on localhost testing machine, might work well on actual domain.

Setting up vhost and pointing using hosts file shall do the trick...

magento 1.5

Magento 1.5 doesnt allow one to addjs or addskinjs with a custom sorting order...
its because the head.phtml file is doesn't support it in getCssJsHtml() and getIncludes();

One way to solve it is to inject script directly into head.phtml, but put it into your own template folder...
copy from app/design/frontend/base/default/template/page/html/head.phtml to
app/design/frontend/[yourtemplate]/default/template/page/html/

Another thing to take note is getUrl and getSkinURL gotcha...
Example:
$this->getSkinUrl("js/java.js"); // return skin/frontend/[base_or_yourtemplate]/default/js/java.js
but
$this->getUrl("js/java.js"); // return http://yourbasepath.com/js/java.js/


Work around will be using $this->getUrl(""). "js/java.js"

netonboard.com sucks?

Updates 2012 jan 18:
Finally, got their attention from facebook fanpage. Talked to their support, and got my email replied.
They should check their offline chat message if its provided on their website...


-----------------------------------------------------------------
Well, i tried to be professional in judging them.
If it wasn't because the client bought the hosting with them, i might not have to face their shit.


First, they change their hosting without our notice.
Previously things which works, now doesn't work, and they claim they never change anything,


In php point of programmer view, they disable error log.
Fine, as programmer, i will use ini_set to enable it to see what went wrong.
so my surprise, it came out error 500 instead.
so defnitely it has been disabled ini_set function... wth..


Next, if you php code doesnt close with ?>, it will also come out error 500, isn't this a norm in php to have unclosed tag? its to avoid unwanted endline charactor in the end to avoid being output out.

Facebook App session issue after user logout or close browser

It seems that Facebook PHP SDK does not properly check if user have logged out or close the browser.
When someone closes the browser or log out of facebook, the php sdk should detect the problem and automatically destroy the session, but it doesnt seems to be the case, even when we call $fb->destroySession();

One way to effectively check for problem is to use Facebook javascript sdk by subscribing to :

----------
FB.Event.subscribe('auth.logout', function(response) {
      if (response.status=="unknown") {
        //some weird session error
        document.location.href="login.php";
        return;
      }
      doTimerReload();
    });
----------
The code effectively detect the logout with "unknown" status and redirect the user to a login screen.
Example of a login.php code:

Please <a href="javascript:">click here</a><br /> <script>

function doFBLogin() {

FB.login(function(response) {

  if (response.authResponse) {

   FB.api('/me', function(response) {

   });

  } else {

   alert("Please authorize app by refreshing to continue...");

  }

  }, {scope: 'email,user_likes'}); //additional parameter

}

</script><br /> ----------

If you are facing memory heap size problem with java, try following this link:
http://www.thatsmyview.net/2010/04/17/optimizing-performance-for-vps-and-low-ram/
and also set your default heap size in java by editing ~/.bash_profile
export _JAVA_OPTIONS=-Xmx100m


#If your mail have not been deliver, try check the que by running:
sudo mailq

#if you encounter some file(1) utils missing, install it by running:
sudo yum install file

#If you are running zimbra from a openvz vps, please ensure min 3Gb of burst memory. Or it wont run properly. The problem is due to missing swap in openvz. So it will need sufficient memory to run.
