Guest Wishlist In Magento 2

Introduction

Magento 2 provides a robust e-commerce platform for businesses to create and manage their online stores. One of the key features of Magento 2 is its ability to handle customer wishlists, which allows customers to save products they are interested in purchasing for later. However, for guest customers, Magento 2 does not provide a built-in feature to save wishlists. In this article, we will discuss how to implement a custom guest wishlist in Magento 2.

Understanding the Requirements

To implement a custom guest wishlist in Magento 2, we need to understand the requirements of the feature. A guest wishlist should allow customers to save products without creating an account. The wishlist should be accessible from the customer's account dashboard, and the products should be stored in the customer's session. We also need to consider the cookie policy, as the wishlist will be stored in the customer's browser cookies.

Magento 2.2.4 and Cookie Policy

Magento 2.2.4 has a strict cookie policy, which requires that all cookies be explicitly declared and obtained user consent before being set. This means that we need to declare the cookie used to store the guest wishlist and obtain user consent before setting it.

Step 1: Create a Custom Module

To implement the guest wishlist feature, we need to create a custom module in Magento 2. We will create a new module called GuestWishlist and add the necessary files to it.

Step 1.1: Create the Module Directory

Create a new directory called GuestWishlist in the app/code directory of your Magento 2 installation.

mkdir -p app/code/GuestWishlist

Step 1.2: Create the Module Files

Create the following files in the GuestWishlist directory:

• GuestWishlist/etc/module.xml
• GuestWishlist/etc/di.xml
• GuestWishlist/Model/Wishlist.php
• GuestWishlist/Model/WishlistItem.php
• GuestWishlist/Block/Wishlist.php
• GuestWishlist/Block/WishlistItem.php
• GuestWishlist/Controller/Index/Index.php
• GuestWishlist/Controller/Index/Add.php
• GuestWishlist/Controller/Index/Remove.php

Step 1.3: Define the Module in module.xml

In the module.xml file, define the module and its dependencies.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="GuestWishlist" setup_version="1.0.0">
        <sequence>
            <module name="Magento_Wishlist"/>
        </sequence>
    </module>
</config>

Step 1.4: Define the Module in di.xml

In the di.xml file, define the module's dependencies and services.

<?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="Magento\Wishlist\Model\Wishlist" type="GuestWishlist\Model\Wishlist"/>
    <preference for="Magento\Wishlist\Model\WishlistItem" type="GuestWishlist\Model\WishlistItem"/>
    <preference for="Magento\Wishlist\Block\Wishlist" type="GuestWishlist\Block\Wishlist"/>
    <preference for="Magento\Wishlist\Block\WishlistItem" type="GuestWishlist\Block\WishlistItem"/>
    <preference for="Magento\Wishlist\Controller\Index\Index" type="GuestWishlist\Controller\Index\Index"/>
    <preference for="Magento\Wishlist\Controller\Index\Add" type="GuestWishlist\Controller\Index\Add"/>
    <preference for="Magento\Wishlist\Controller\Index\Remove" type="GuestWishlist\Controller\Index\Remove"/>
</config>

Step 1.5: Implement the Wishlist Model

In the Wishlist.php file, implement the wishlist model.

namespace GuestWishlist\Model;
use Magento\Wishlist\Model\Wishlist as MagentoWishlist;
class Wishlist extends MagentoWishlist
{
public function saveWishlist($wishlistData)
{
// Save the wishlist data to the customer's session
$wishlist = $this->getWishlist();
wishlist->save(wishlistData);
return $wishlist;
}
public function getWishlist()
{
    // Get the wishlist from the customer's session
    $wishlist = $this->getCustomerSession()->getWishlist();
    if (!$wishlist) {
        $wishlist = $this->createWishlist();
    }
    return $wishlist;
}

public function createWishlist()
{
    // Create a new wishlist
    $wishlist = new \Magento\Wishlist\Model\Wishlist();
    $this->getCustomerSession()->setWishlist($wishlist);
    return $wishlist;
}

public function getCustomerSession()
{
    // Get the customer's session
    return \Magento\Customer\Model\Session::getInstance();
}

}

Step 1.6: Implement the Wishlist Item Model

In the WishlistItem.php file, implement the wishlist item model.

namespace GuestWishlist\Model;
use Magento\Wishlist\Model\WishlistItem as MagentoWishlistItem;
class WishlistItem extends MagentoWishlistItem
{
public function saveWishlistItem($wishlistItemData)
{
// Save the wishlist item data to the customer's session
$wishlistItem = $this->getWishlistItem();
wishlistItem->save(wishlistItemData);
return $wishlistItem;
}
public function getWishlistItem()
{
    // Get the wishlist item from the customer's session
    $wishlistItem = $this->getCustomerSession()->getWishlistItem();
    if (!$wishlistItem) {
        $wishlistItem = $this->createWishlistItem();
    }
    return $wishlistItem;
}

public function createWishlistItem()
{
    // Create a new wishlist item
    $wishlistItem = new \Magento\Wishlist\Model\WishlistItem();
    $this->getCustomerSession()->setWishlistItem($wishlistItem);
    return $wishlistItem;
}

public function getCustomerSession()
{
    // Get the customer's session
    return \Magento\Customer\Model\Session::getInstance();
}

}

Step 1.7: Implement the Wishlist Block

In the Wishlist.php file, implement the wishlist block.

namespace GuestWishlist\Block;
use Magento\Wishlist\Block\Wishlist as MagentoWishlistBlock;
class Wishlist extends MagentoWishlistBlock
{
public function getWishlist()
{
// Get the wishlist from the customer's session
return $this->getCustomerSession()->getWishlist();
}
public function getCustomerSession()
{
    // Get the customer's session
    return \Magento\Customer\Model\Session::getInstance();
}

}

Step 1.8: Implement the Wishlist Item Block

In the WishlistItem.php file, implement the wishlist item block.

namespace GuestWishlist\Block;
use Magento\Wishlist\Block\WishlistItem as MagentoWishlistItemBlock;
class WishlistItem extends MagentoWishlistItemBlock
{
public function getWishlistItem()
{
// Get the wishlist item from the customer's session
return $this->getCustomerSession()->getWishlistItem();
}
public function getCustomerSession()
{
    // Get the customer's session
    return \Magento\Customer\Model\Session::getInstance();
}

}

Step 1.9: Implement the Index Controller

In the Index.php file, implement the index controller.

namespace GuestWishlist\Controller\Index;
use Magento\Wishlist\Controller\Index\Index as MagentoIndexController;
class Index extends MagentoIndexController
{
public function execute()
{
// Get the wishlist from the customer's session
$wishlist = this->getCustomerSession()->getWishlist();
        if (!wishlist) {
$wishlist = $this->createWishlist();
}
return this->resultRedirectFactory->create()->setUrl(this->_url->getUrl('wishlist/index'));
}
public function createWishlist()
{
    // Create a new wishlist
    $wishlist = new \Magento\Wishlist\Model\Wishlist();
    $this->getCustomerSession()->setWishlist($wishlist);
    return $wishlist;
}

public function getCustomerSession()
{
    // Get the customer's session
    return \Magento\Customer\Model\Session::getInstance();
}

}

Step 1.10: Implement the Add Controller

In the Add.php file, implement the add controller.

namespace GuestWishlist\Controller\Index;
use Magento\Wishlist\Controller\Index\Add as MagentoAddController;
