您可以通过两种方式获取已删除的购物车商品：

• 从 WC_Cart 对象中使用：

  $removed_items = WC()->cart->get_removed_cart_contents();

• 从 WC_Session 对象中使用：

  $removed_items = WC()->session->get('removed_cart_contents');

要定位特定的已删除产品并获取其密钥 ID（以及撤消 URL 或从中删除 URL），请使用：

$targeted_product_id = 25; // Set the product ID to target
$targeted_item_key   = ''; // Initializing

// Get removed cart items
$removed_items = WC()->cart->get_removed_cart_contents();

// Loop through removed cart items
foreach( $removed_items as $item_key => $item ) {
    $product_id   = $item['product_id'];
    $variation_id = $item['variation_id'];

    if( in_array($targeted_product_id, [$product_id, $variation_id]) ) {
        $targeted_item_key = $item_key; 
        break;
    }
}
// get the Undo URL
$undo_url = WC()->cart->get_undo_url( $targeted_item_key );

// Test output Undo URL
echo ''. __("Undo Url") . '';

// get the remove URL
$remove_url = WC()->cart->get_remove_url( $targeted_item_key );

// Test output remove URL
echo ''. __("Remove Url") . '';
