I have two different headers in my Magento one for retail shop and second is for commercial shop in same store view. In both header Product category will be same.

  • Condition #1 :- In retail shop when we click on "Products" category then it will be list all products.
  • Condition #2 :- when I will change click on commercial shop header then it will be show only commercial products I have assigned custom attribute for it. Is this possible ?

I found code for loaded product collection in this file \app\code\core\Mage\Catalog\Block\Product\List.php can we add attribute filter in this function ?

protected function _getProductCollection()
        if (is_null($this->_productCollection)) {
            $layer = $this->getLayer();
            /* @var $layer Mage_Catalog_Model_Layer */
            if ($this->getShowRootCategory()) {

            // if this is a product view page
            if (Mage::registry('product')) {

                // get collection of categories this product is associated with
                $categories = Mage::registry('product')->getCategoryCollection()
                    ->setPage(1, 1)

                // if the product is associated with any category
                if ($categories->count()) {
                    // show products from this category

            $origCategory = null;
            if ($this->getCategoryId()) {
                $category = Mage::getModel('catalog/category')->load($this->getCategoryId());
                if ($category->getId()) {
                    $origCategory = $layer->getCurrentCategory();
            $this->_productCollection = $layer->getProductCollection();


            if ($origCategory) {

        return $this->_productCollection;
  • You can also refer the link where Sorting of product by attributes. inchoo.net/magento/magento-products/… Help of above example you can add you own attribute. – Somnath Jul 20 '15 at 9:39
  • Can you find the way to filter product collection on layered navigation and category page using attribute,if you find than please post it... – ND17 Jan 28 '16 at 10:46
  • @ND17 have you tried below mentioned Piyush's code ? – Arunendra Jan 28 '16 at 11:01
  • yes but its only filter in category page not in layered navigation and toolbar is also not given correct item – ND17 Jan 28 '16 at 11:03
  • have you tried it in toolbar.php public function setCollection($collection)() ?? – Arunendra Jan 28 '16 at 11:20

For your second Condition you can Filter Your Product Collection Like This :-

    ->addAttributeToFilter('your_custom_attribute_code', 'your_custom_attribute_value');

You Can Add this filter at File list.php

app\code\core\Mage\Catalog\Block\Product\List.php Find The setCollection method

and under $this->_productCollection = $collection;

add this code

$collection->addAttributeToFilter('your_custom_attribute_code', 'your_custom_attribute_value');

    I think it's addAttributeToFilter for product collections, not addFieldToFilter. – Marius Jul 20 '15 at 6:03
  • @Piyush I know this type filter but i need it done in product list so it will also apply on layer navigation see my updated question. – Arunendra Jul 20 '15 at 6:13
  • @Arunendra you can apply this filter on setCollection method of block file. – Piyush Jul 20 '15 at 6:20
  • @Piyush you mean in list.phtm can you show me query for it. – Arunendra Jul 20 '15 at 6:25
  • @Arunendra I have updated the answer. – Piyush Jul 20 '15 at 6:31
