In Magento 2, by default, a maximum of four products are displayed in the cross-selling section of the cart. In many stores, this limitation is burdensome – especially when the offer is extensive.

Default cross-sell limit in Magento 2

In a standard Magento 2 installation, the limit of cross-selling products in the cart is 4. This value is permanently defined in the Magento_Checkout module and cannot be changed from the administration panel.

Where the cross-sell limit is defined

The limit is defined in the Magento_Checkout module – in the Crosssell class. File path: vendor/magento/module-checkout/Block/Cart/Crosssell.php.

As we mentioned above, Magento does not provide configuration for this, so the only correct solution is to overwrite the class using your own module.

Changing the cross-sell limit via your own module

You need to create files:

– preference registration file (di.xml)

– file overwriting the limit

LionBrothers/CrosssellLimit/etc/frontend/di.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Checkout\Block\Cart\Crosssell" type="LionBrothers\CrosssellLimit\Block\Cart\Crosssell"/>
</config>

LionBrothers/CrosssellLimit/Block/Cart/Crosssell.php

<?php

namespace LionBrothers\CrosssellLimit\Block\Cart;

class Crosssell extends \Magento\Checkout\Block\Cart\Crosssell
{
    /**
     * Items quantity will be capped to this value
     *
     * @var int
     */
    protected $_maxItemCount = 8;
}

You also need to remember the standard files of each module – registration.php and module.xml.

Why preference? Why not plugin?

In this case, the cross-sell product limit is set as a protected property, not a method. This means we can’t change it via plugin (before/after/around). The simplest solution (and best practice) is to use preference and extend the original class.

In Magento 2, CMS blocks are most often used directly in XML layouts. However, there are times when you need to display a CMS block directly in a PHTML file, for example, with conditional logic. In this post, we’ll explain how to properly invoke a CMS block in .phtml files.

Calling a CMS block in .phtml

<?php
echo $this->getLayout()
->createBlock('Magento\Cms\Block\Block')
->setBlockId('id_bloku_cms')
->toHtml();
?>

Instead of “cms_block_id” enter the static CMS block ID.

Important: enter the ID set on the panel side, not the ID from the database.

Calling a CMS block on a CMS page

If a CMS block is to be used inside the content of a CMS page, the following directive should be used:

{{block class="Magento\\Cms\\Block\\Block" block_id="id_bloku_cms"}}

Calling a static CMS block via an xml (layout) file

<referenceContainer name="product.info.main"> 
    <block class="Magento\Cms\Block\Block" name="block_identifier"> 
        <arguments> 
            <argument name="block_id" xsi:type="string">id_bloku</argument> 
        </arguments> 
    </block> 
</referenceContainer>
