Override Third Party Module

[rui_silva1]

Hey,

So I want to extend a Third Party plugin, in this case the Moloni Plugin for Magento 2.

I want to override a function in this file 

\Vendor\moloni\magento2\Libraries\MoloniLibrary\Controllers\Products.php

I tried to create a di.xml in

code\Magento\Moloni\Libraries\MoloniLibrary\etc\di.xml

with 

<?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="Vendor\moloni\magento2\Libraries\MoloniLibrary\Controllers\Products" type="Moloni\Libraries\MoloniLibrary\Controllers\Products" />
</config>

and then in

\code\Magento\Moloni\Libraries\MoloniLibrary\Controllers\Products

this

<?php
namespace Moloni\Libraries\MoloniLibrary\Controllers\Products;

class Products extends \Vendor\moloni\magento2\Libraries\MoloniLibrary\Controllers\Products {
   
//All the code from the original file

}

but does not work, what am I doing wrong?

Hello @rui_silva1 

Seems like you mention wrong path.

Try to open that controller file and take namespace and file name and put into di.xml

hope it will help you.

If works then mark as a solution

Hello @Sunil Patel ,

Thanks for the reply.

In the mean time I tried some things, my di.xml it's like this

<?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="moloni\magento2\Libraries\MoloniLibrary\Controllers\Products" type="Vendor\Moloni\Libraries\Products" />
</config>

and the Products.php

<?php 

namespace Vendor\Moloni\Libraries;
use moloni\magento2\Libraries\MoloniLibrary\Controllers\Products as vendormoloni;

class Products extends vendormoloni
{
//Code
}

i made a registration.php and all worked until I run di:compile that tells me that in Products.php the file orginal it's not found in this path, but isn't that the path? do I need to add the Vendor\ ?

moloni\magento2\Libraries\MoloniLibrary\Controllers\Products 

and if I remove the as and extend the error is that the name already exists

Hello @rui_silva1 

Try the below code in 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="Invoicing\Moloni\Libraries\MoloniLibrary\Controllers\Products" type="[Vendor]\[Module]\Libraries\Products" />
</config>

In Products.php,

<?php
namespace [Vendor]\[Module]\Libraries;
use Invoicing\Moloni\Libraries\MoloniLibrary\Controllers\Products as vendormoloni
class Products extends vendormoloni
{
	// code
}

Here, [Vendor] and [Module] is your custom/existing module/plugin.

Note:

To override vendormoloni not extends/inherit private variable and function you redefine it.

Thanks.
