How to filter product list by custom attribute on category page of Magento?

问题

I made 3 tabs on category page, which are All Products, Online Products and Store Only Products.

All products display all products under this category.

I use

{{block type="catalog/product_list" template="catalog/product/list.phtml"}}

to do the job.

Online Products will display custom attribute (product_type) equals "Online Product"

Store Only Products will display custom attribute (product_type) equals "Store Only Product"

How can I create a block to display Online Products and Store Only Products under this category?

回答1:

The easiest way is to make a duplicate of the List block and add the filter you need.

You May need to modify your attribute in the Magento admin area to "show in product listing" too.

for example:

{{block type="catalog/product_list" template="catalog/product/list.phtml"}}

this will use the List block to filter the collection for you, lets make a copy:

app/code/core/Mage/Catalog/Block/Product/List.php

app/code/local/Mage/Catalog/Block/Product/Mylist.php

Now lets modify the Block to use our custom attribute, something like this should work (not tested)

Mylist.php

class Mage_Catalog_Block_Product_Mylist extends Mage_Catalog_Block_Product_List
{
    /**
     * Retrieve loaded category collection
     *
     * @return Mage_Eav_Model_Entity_Collection_Abstract
     */
    protected function _getProductCollection()
    {
        $collection = parent::_getProductCollection();

        $collection->addAttributeToSelect('my_attribute')
            ->addAttributeToFilter('my_attribute', array('eq' => '000001'))
        ;

        return $collection;
    }
}

Now you simple use your new block:

{{block type="catalog/product_mylist" template="catalog/product/list.phtml"}}

Never, but NEVER, create or modify a Magento CORE class. The answer is to implement your module, override the List block class and customize the method _getProductCollection.
