How to display all wishlist items in wishlist sidebar

Question

i Want to display all wish-list items in the sidebar?

Currently only last added three items are showing up.

I wanted to display all items in current wishlist selection.

What should I change in this file:

vendor/magento/module-wishlist/view/frontend/templates/sidebar.phtml

Answer 1

You can do it by plugin or overwrite of **Magento\Wishlist\CustomerData\Wishlist**. I will cover pluginize **getSectionData** for achieving this.

VendorName/ModuleName/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">
    <type name="Magento\Wishlist\CustomerData\Wishlist">
        <plugin name="customer_data_wishlist" type="VendorName\ModuleName\Plugin\Wishlist\CustomerData\Wishlist" sortOrder="1"/>
    </type>
</config>

> namespace VendorName\ModuleName\Plugin\Wishlist\CustomerData;

}

Clear cache.

NB: Only refresh is not enough for testing working or not. Add/Remove wishlist item then magento fire sidebar section data and load.

Answer 2

Try This

Magento\Wishlist\CustomerData\Wishlist

In line Number 20 Change

const SIDEBAR_ITEMS_NUMBER = 3;

TO

const SIDEBAR_ITEMS_NUMBER = 10;
