How to get Wishlist Items by customer id in Magento 2?

Here, we are discussing how to get wishlist items of the customer by customer id.

You can display Customer Wishlist item details in the store.

Use Magento\Wishlist\Model\Wishlist Model file to get Wishlist.

Create Block to load Wishlist collection.

<?php
namespace Magemonkey\Wishlist\Block;

class Magemonkeydemo extends \Magento\Framework\View\Element\Template
{
public function __construct(
\Magento\Framework\View\Element\Template\Context $context,
\Magento\Wishlist\Model\Wishlist $wishlist,
array $data = []
) {
$this->wishlist = $wishlist;
parent::__construct($context,$data);
}

/**
* @param int $customerId
*/
public function getWishlistByCustomerId($customerId)
{
$wishlist = $this->wishlist->loadByCustomerId($customerId)->getItemCollection();
return $wishlist;
}
}
?>

<?php

namespace Magemonkey\Wishlist\Block;

class Magemonkeydemo extends \Magento\Framework\View\Element\Template

{

public function __construct(

\Magento\Framework\View\Element\Template\Context $context,

\Magento\Wishlist\Model\Wishlist $wishlist,

array $data = []

) {

$this->wishlist = $wishlist;

parent::__construct($context,$data);

}

/**

* @param int $customerId

public function getWishlistByCustomerId($customerId)

{

$wishlist = $this->wishlist->loadByCustomerId($customerId)->getItemCollection();

return $wishlist;

}

Now, add below code and call the function in a template file, It will display wishlist item if found, otherwise “Nothing found in your wishlist!” will be displayed.

<?php
$customerId = 7; /* CUSTOMER'S ID */
$wishlistCollection = $block->getWishlistByCustomerId($customerId);
if(count($wishlistCollection)) {
foreach ($wishlistCollection as $_item) {
/* You can get ID, Name, Desc. ... */
echo $_item->getProduct()->getId();
}
} else {
/* Display message if no item found in wishlist */
echo __("Nothing found in your wishlist!");
}
?>

<?php

$customerId = 7; /* CUSTOMER'S ID */

$wishlistCollection = $block->getWishlistByCustomerId($customerId);

if(count($wishlistCollection)) {

foreach ($wishlistCollection as $_item) {

/* You can get ID, Name, Desc. ... */

echo $_item->getProduct()->getId();

}

} else {

/* Display message if no item found in wishlist */

echo __("Nothing found in your wishlist!");

}
