If you encounter this error message on a Symfony2 project, you just have to install php5-intl module
apt-get install php5-intl
And don’t forget to restart apache
service apache2 restart
If you need to create an observer on your custom entities, just follow these few steps:
In this case, we will create an observer on the before save event of the tarif entity.
On your module config.xml file, declare your observer, this will bind your hook event to your class/method
<config>
<global>
<events>
<tarif_save_before>
<observers>
<adin_marketplace>
<type>singleton</type>
<class>adin_marketplace/observer</class>
<method>adinMarketplaceTarifSaveBefore</method>
</adin_marketplace>
</observers>
</tarif_save_before>
</event>
</global>
/config>
tarif_save_before means your observer will trigger on the before save event of the tarif entity.
To find out which entity to use, you can add (temporary) a mage::log() on this class : app/code/core/Mage/Core/Model/Abstract.php
protected function _beforeSave()
{
if (!$this->getId()) {
$this->isObjectNew(true);
}
Mage::dispatchEvent('model_save_before', array('object'=>$this));
Mage::log('entity to use: '.$this->_eventPrefix.'_save_before');
Mage::dispatchEvent($this->_eventPrefix.'_save_before', $this->_getEventData());
return $this;
}
adin_marketplace is my module.
adin_marketplace/observer class is the class file to use (app/code/local/Adin/Marketplace/Model/Observer.php )
adinMarketplaceTarifSaveBefore is the method inside my class.
Now, create your class and your method : app/code/local/Geophyle/Marketplace/Model/Observer.php
class Adin_Marketplace_Model_Observer {
public function adinMarketplaceTarifSaveBefore($observer)
{
$event = $observer->getEvent();
$tarif = $event->getTarif();
//do some stuff...
}
And that’s all.
You change an .xml file, so don’t forget to clear your cache.
You try to save a product and you get this error : Invalid argument supplied for foreach().
This was unexpected and you don’t understand why.
The problem is, that you are not allowed to save products from the frontend.
The origData property is not filled
public function setOrigData($key=null, $data=null)
{
if (Mage::app()->getStore()->isAdmin()) {
return parent::setOrigData($key, $data);
}
return $this;
}
So when you try to save the product, this error is raised.
What to do when you encounter this error ?
A quick fix is to add this before saving, on your controller for example.
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
A proper solution is to extend Mage_Catalog_Model_Product and replace setOrigData method
public function setOrigData($key = null, $data = null)
{
if (is_null($key)) {
$this->_origData = $this->_data;
} else {
$this->_origData[$key] = $data;
}
return $this;
}
Create a dropdown list with magento’s countries is easy :
<select name="billing_country" id="billing_country">
<?php
$_countries = Mage::getResourceModel('directory/country_collection')->loadData()->toOptionArray(false);
foreach($_countries as $_country)
{
echo '<option ';
if($this->getCustomer()->getBillingCountry() == $_country['value']){ echo 'selected '; }
echo 'value="'.$_country['value'].'">'.$_country['label'].'</option>';
}
?>
</select>
Here a simple but complete example to create a dropdown list for a product attribute
//retrieve informations
$attribute_model = Mage::getModel('eav/entity_attribute');
$attribute_code = $attribute_model->getIdByCode('catalog_product', 'audience');
$attribute = $attribute_model->load($attribute_code);
$attribute_options_model= Mage::getModel('eav/entity_attribute_source_table') ;
$attribute_table = $attribute_options_model->setAttribute($attribute);
$options = $attribute_options_model->getAllOptions(false);
//display them
echo '<select id="audience" class="select" name="audience">';
foreach($options as $option)
{
echo '<option value="'.$option['value'].'">'.$helper->__($option['label']).'</option>';
}
echo '</select>';
Here the easiest way to format a date in PHP
$date = DateTime::createFromFormat('Y-m-d',$_address->getShippingDate());
echo $date->format('d/m/Y');
To load html content of a template inside a controller, for example for ajax response, you can do :
$block = $this->getLayout()->createBlock('adin_admin/adminhtml_scheduletcrender')->setTemplate('admin/scheduletcrender.phtml');
$block->assign(array('ateliers' => $ateliers));
$html = $block->toHtml();
$response = array('html' => $html);
//send response as json
$this->getResponse()->setHeader('Content-type', 'application/json');
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($response));
You need to define a constant containing an array but the code below doesn’t work ?
define('FILTER_ECOLE', array('price, categorie, niveau'));
You get an error :
Notice: Use of undefined constant FILTER_ECOLE - assumed 'FILTER_ECOLE' in /home/www/adin/app/code/local/Adin/Catalog/Block/Nav/Catalog/Layer/View/Sidebar.php on line 50
To define an use a constant containing an array you can simply serialize it :
#define
define('FILTER_ECOLE', serialize(array('price, categorie, niveau')));
#use
$filter = unserialize(FILTER_ECOLE);
This is how you can update attribute parameters, the one saved in catalog_eav_attribute table
In this exemple we will enable the “used_in_product_listing” params of the “code_catalogue” attribute
$attributeId = Mage::getResourceModel('eav/entity_attribute')->getIdByCode('catalog_product','code_catalogue');
if ($attributeId) {
$attribute = Mage::getModel('catalog/resource_eav_attribute')->load($attributeId);
$attribute->setUsedInProductListing(1)->save();
}
And that’s all.
You can easily know “where you are” using these fonctions :
in template / block files
$this->getRequest()->getRouteName(); $this->getRequest()->getModuleName(); $this->getRequest()->getControllerName(); $this->getRequest()->getActionName();
in class files
Mage::app()->getRequest()->getRouteName(); Mage::app()->getRequest()->getModuleName(); Mage::app()->getRequest()->getControllerName(); Mage::app()->getRequest()->getActionName();
