This week’s task was optimising Magento for large carts (100+ different products) and a profiler is a good tool to find small pieces of code that could be optimised. Blackfire was my choice, mostly because previous experience, but also because it is not a resource hog like Xdebug, which was taking around 6 minutes while Blackfire took only 20 seconds in the same type of request. Companion Blackfire works great to profile GET requests on the browser with the help of Companion, but it doesn’t allow you to profile POST requests. Also, Companion sends multiple requests to the same endpoint, but Magento’s place order is not stateless, so the first and all other request would differ substantially. ...

Today I was working in a 3rd party module. Something very simple, an AJAX Add to Cart button. But, when I requested http://.../ajaxcart/cart/add, I’ve got a 302 HTTP status, or, a redirect, to the same requested URL, but in secure mode (HTTPS). After debugging, I could understand that the controller wasn’t being called, so I try to find a configuration problem. The Administration Panel was configured to be served on HTTPS (Configuration > General > Web > Secure > ???), and when I’ve removed this option, everything was working as expected. ...

Quick tip: When have a code like this: {% raw %}{% trans %}prefix.{{ varname }}{% endtrans %}{% endraw %} And receive this error: Twig_Error_Syntax: A message inside a trans tag must be a simple text You can use the following piece of code as workaround. {% raw %}{{ ("prefix." ~ varname)|trans }}{% endraw %} PS: maybe this is not the best way to go.

Hi folks, Today I struggled over an already known bug on Symfony2 when using UniqueEntity and Entity Inheritance. In the bug discussion, @gentisaliu recommended using a custom repository, and how do this I’m documenting here. Entities: /** * @ORM\Table(name="parent") * @ORM\Entity(repositoryClass="Repository\Parent") * @UniqueEntity(fields={"name"}, repositoryMethod="findByName", message="Name already used.") * @ORM\InheritanceType("JOINED") * @ORM\DiscriminatorColumn(name="type", type="string") * @ORM\DiscriminatorMap({ * "a" = "ChildA", * "b" = "ChildB" * }) */ class Parent { } /** * @ORM\Entity(repositoryClass="Repository\Parent") * @ORM\Table(name="child_a") */ class ChildA extends Parent { } /** * @ORM\Entity(repositoryClass="Repository\Parent") * @ORM\Table(name="child_b") */ class ChildB extends Parent { } repositoryMethod: ...

Hi Folks, A little note to work with product object in Magento: /** * Using setStoreId two times, otherwise it will save the data to default store */ $product = Mage::getModel('catalog/product') ->setStoreId($storeId) ->loadByAttribute('ean', $ean) ->setStoreId($storeId);

Hello. After an intense debug into Magento, we (Filipe Ibaldo and me) have found two problems in Magento code, related to slow Place Order with many products in cart (not many qty of a product). One of the problems is the order item save, which is executed precisely in app/code/core/Mage/Sales/Model/Entity/Order/Attribute/Backend/Parent.php, on afterSave method, who spent many time on my machine (Core 2 Duo 2.26/4GB RAM), about 0.3 second for each product. ...

Hello. Today I found a problem in Zend Framework and his class autoloader, where an class_exists function call fires the Zend Framework autoloader. The function has an option to ignore the autoloader, but any class that I need loaded by Zend_Loader will return false. Then, if I call class_exists without disable autoloader, I got an file not exists PHP warning, that’s why Zend_Loader doesn’t check if the file exists, just include. ...
