Right now, I'm simply attempting to override the Pager class. Without changing anything within it, I've copied it into my module, and then specified the preference in the di:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Theme\Block\Html\Pager" type="MyVendor\Core\Block\Html\Pager"/>
</config>

Problem is, after doing so, I run into a Type Error when creating an Item class:

1 exception(s):
Exception #0 (Magento\Framework\Exception\RuntimeException): Type Error occurred when creating object: Magento\Catalog\Model\Layer\Filter\Item

Exception #0 (Magento\Framework\Exception\RuntimeException): Type Error occurred when creating object: Magento\Catalog\Model\Layer\Filter\Item

Any ideas as to what is going on here?

Alright, I think I'm beginning to understand a little. Item is injecting \Magento\Theme\Block\Html\Pager, and throwing an error as my class doesn't match, even though I'm overriding it with the di preference. Any way around this?

  • try to run setup upgrade , static content deploy , clear chache and then check – Rk Rathod Apr 10 at 21:16

In order to get past the Type Error, I had to change my Pager to extend the base Pager class as opposed to the base Template class as the original did.

In di.xml use,

<preference for="Magento\Theme\Block\Html\Pager" type="MyVendor\Core\Block\Html\Pager"/>

In MyVendor\Core\Block\Html\Pager use,

namespace MyVendor\Core\Block\Html;

Extend the class by using,

class Pager extends \Magento\Theme\Block\Html\Pager
{
public function MyCustomFunction()

{
   return "working";

} 
}
