The custom SQL code (ModuleName_Catalog_Model_Resource_Eav_Mysql4_Product_Collection) is not required, and infact it makes the collection class less useful.

Insead you should simply use the existing addAttributeToFilter function, passing in the following:

$$categoryId1 = 10;
$$categoryId1 = 12;
$this->_productCollection->addAttributeToFilter(
\’category_ids\’,array(
array(\’finset\’=>array($categoryId1)),
array(\’finset\’=>array($categoryId2))
)
);

This has the advantage of working even if products are assigned to more than one category. And can filter collections which have already been filtered by a seperate category.

Hi,

I’ve also implemented (or tried to anyway) your code, but I can’t get it to work.
I’ve already tried putting this line ModuleName_Catalog_Model_Resource_Eav_Mysql4_Product_Collection

on a single line, but that didn’t help.
I’m running magento 1.3.2.4

Any suggestions?

Thx in advance

Because a Magento’s bug if you put
[...]

ModuleName_Catalog_Model_Resource_Eav_Mysql4_Product_Collection

[...]
in two lines is not going to work.
Leave as follow:

ModuleName_Catalog_Model_Resource_Eav_Mysql4_Product_Collection

By the way, really useful code! I love it!
