To add in admin as a list field:
override/controllers/admin/Admin[Name]Controller.php
in __construct():
$this->fieldImageSettings = array(
'name' => 'image', //form name
'dir' => 'name'//img/
name
);
$this->imageType = "jpg";
in __construct() or ajaxProcessDetails(): //depending on extended controller
$this->fields_list['image'] = array(
'title' => $this->l('Image'),
'width' => 70,
"image" => $this->fieldImageSettings["dir"]
);
if helper is generated manually:
//$this->setHelperDisplay($helper); // this is full helper
$helper->imageType = $this->imageType;
in __construct() or renderForm or renderForm[Name] //depending on extended controller
$this->fields_form["input"][] = array(
'type' => 'file',
'label' => $this->l('Image:'),
'name' => 'image',
'required' => false,
'display_image' => true
);
In override/classes/modelname.php
in __construct():
$this->image_dir = "name"; //points to same path as fieldImageSettings["dir"] above
if you generate custom thumb based on alias name, makesure to clear all cache files in tmp with this additional function in Model Class:
public function deleteImage($force_delete = false) {
$res = parent::deleteImage($force_delete);
if ($res) {
//clear cached file
$files = array(
$table.'_mini_'.$this->id.'.'.$type,
$table.'_thumb_'.$this->id.'.'.$type
);
foreach($files as $file) {
if (file_exists(_PS_TMP_IMG_DIR_.$file)) {
unlink(_PS_TMP_IMG_DIR_.$file);
}
}
}
return $res;
}
