This is going to be the best option for you.

app/code/Vendor/Wishlist/etc/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">
    <type name="Magento\Wishlist\CustomerData\Wishlist">
        <plugin disabled="false" name="Vendor_Wishlist_Plugin_Magento_Wishlist_CustomerData_Wishlist" sortOrder="10" type="Vendor\Wishlist\Plugin\Magento\Wishlist\CustomerData\Wishlist"/>
    </type>
</config>

app/Vendor/Wishlist/Plugin/Magento/Wishlist/CustomerData/Wishlist

    <?php

declare(strict_types=1);

namespace Vendor\Wishlist\Plugin\Magento\Wishlist\CustomerData;


class Wishlist
{

    protected $wishlistHelper;

    public function __construct(
        \Magento\Wishlist\Helper\Data $wishlistHelper
    )
    {
        $this->wishlistHelper = $wishlistHelper;
    }


    public function afterGetSectionData(
        \Magento\Wishlist\CustomerData\Wishlist $subject,
        $result
    ) {

        // Your code here

        return $result;
    }
}

  • Well you don't add it inside a function you would add it after the afterGetSectionData function Apr 9, 2021 at 14:54
  • Also you cannot overwrite a protected function you would need to do you modifications in the afterGetSectionData function Apr 9, 2021 at 14:56
  • I am getting confused, 1) should i add the function which i edit in the core wishlist.php after the afterGetSectionData right? ( code : codeshare.io/anxjMV )
