How to override productcollection.php from vendor?

Question

I have to override the file ProductCollection.php from vendor/magento/module-catalog/Ui/DataProvider/Product.

I have read many posts but still not getting to override the file.

Can anyone please explain it to me step by step?

Your help is greatly appreciated.

Answer 1

In order to override

First create di.xml in your module Namespace/Module/etc/di.xml

<type name="Magento\Catalog\Model\ResourceModel\Product\Collection">
    <plugin name="product-collection-sorting" type="Namespace\Module\Plugin\Product\Collection" sortOrder="1"/>
</type>

Create Namespace\Module\Plugin\Product\Collection.php and pasted below code in your file:

<?php
namespace Namespace\Module\Plugin\Product;

class Collection
{

    //do stuff here like override functions
}

I hope this will help

Answer 2

Instead of overriding the Product collection you can create a plugin on the public function of ProductCollection.php. It is a recommended way for doing any modification to core files.
