If I need to create a method under Magento\Catalog\Test\Block\Product\ListProduct Class

This class has methods such as: getProductItem,getProductNames,getProductsCount,getSortByValues

I Would like to make myOwnMethod in my custom module without overwriting it the class ListProduct and use in:


  • You need to change that block class in the XML and then point to your custom block class which extends the Magento\Catalog\Test\Block\Product\ListProduct block class (if you want to keep functionality) Commented Nov 29, 2018 at 16:44

The first thing you want to do is create a class which extends ListProduct. In your custom module's Vendor/Module/Block/Product/ListProduct.php

class ListProduct extends \Magento\Catalog\Block\ListProduct {

    public function myOwnMethod() { … }


And then, you need to replace the references to that block in the layout. I believe the layout that uses this block is catalog_category_view, so in your module's Vendor/Module/view/frontend/layout/catalog_category_view.xml

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="2columns-left" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
        <referenceBlock name="category.products.list" remove="true"/>
        <block class="Vendor\Module\Block\Product\ListProduct" name="category.products.list.extend" as="product_list" template="Vendor_Module::product/list.phtml">
            <container name="category.product.list.additional" as="additional" />
            <block class="Magento\Framework\View\Element\RendererList" name="category.product.type.details.renderers" as="details.renderers">
                <block class="Magento\Framework\View\Element\Template" name="category.product.type.details.renderers.default" as="default"/>
            <block class="Magento\Catalog\Block\Product\ProductList\Item\Container" name="category.product.addto" as="addto">
                <block class="Magento\Catalog\Block\Product\ProductList\Item\AddTo\Compare"
                       name="category.product.addto.compare" as="compare"
            <block class="Magento\Catalog\Block\Product\ProductList\Toolbar" name="product_list_toolbar" template="Magento_Catalog::product/list/toolbar.phtml">
                <block class="Magento\Theme\Block\Html\Pager" name="product_list_toolbar_pager"/>
            <action method="setToolbarBlockName">
                <argument name="name" xsi:type="string">product_list_toolbar</argument>

Notice that this is nearly a perfect copy of the old catalog_category_view.xml but the previous block was removed, and replaced with a new block that has a different class and template

  • I don't want to remove the current category.products.list or change template="Vendor_Module::product/list.phtml" in my vendor all I want is to be able to have a method available to use in any Theme list.phtml without having to add directly to` vendor\magento\module-catalog\Block\Product\ListProduct.php` file. Like appending a new Method onto \Magento\Catalog\Block\ListProduct ready to be used whenever is required. Commented Nov 29, 2018 at 20:56

I think this is probably the only solution I've got welcome new one's please!

Create Block :Vendor/Module/Block/Product/ListProduct.php

in any Theme: .../app/design/frontend/Vendor/Theme/Magento_Catalog/templates/product/list.phtml

Call Block:

$blockStore = $this->getLayout()->createBlock('Vendor/Module/Block/Product/ListProduct');

Use your custom method from Block like so:
