How to display the variation name in Woocommerce Items

I am trying to make a Ajax popup cart where product will be add dynamically. Everything is working fine except the product variation. when a variable product added to cart its not showing the variation name:

<?php 
$items = WC()->cart->get_cart();
    foreach($items as $item => $values) {
        $_product       =  wc_get_product( $values['data']->get_id() );
        $product_link   = get_permalink( $values['data']->get_id() );
        $title          = $_product->get_title();
        $variations     = wc_get_formatted_cart_item_data($values,true);
        echo '<a href="'.$product_link.'">'. $title.'</a>';
        echo $variations;
    }
?>

First, you just need to use WC_Product method get_name() (see in the template cart/minicart.php on line 36) replacing in your code the line:

$title          = $_product->get_title();

with:

$title          = $_product->get_name();

Important Note: In some cases you will need to add the following lines (depending on what you want to display and where):

// Force displaying variation attributes in the product name (in cart/minicart/checkout)
add_filter( 'woocommerce_product_variation_title_include_attributes', '__return_true' );
// (Optional) Force displaying product variation attributes as separated formatted metadata (in cart/minicart/checkout)
add_filter( 'woocommerce_is_attribute_in_product_name', '__return_false' );

Code goes in functions.php file of the active child theme (or active theme).

To test it, once added this code to your theme's functions.php file, empty the cart first, as cart fragments are cached in mini cart (Ajax).

This time it will show the variation name.
