删除产品时，Woocommerce会删除自定义数据

Question

我在每个产品中添加了自定义字段。但是，当用户从购物车中删除产品时，这些自定义字段的会话不会被删除。我想根据产品删除自定义字段。请帮帮我。

 <?php         add_action('woocommerce_before_cart_item_quantity_zero','wdm_remove_user_custom_data_options_from_cart',1,1);
 if(!function_exists('wdm_remove_user_custom_data_options_from_cart'))
 {
 function wdm_remove_user_custom_data_options_from_cart($cart_item_key)
 {
    global $woocommerce;
    // Get cart
    $cart = $woocommerce->cart->get_cart();
    // For each item in cart, if item is upsell of deleted product, delete it
    foreach( $cart as $key => $values)
    {


    if ( $values['wdm_user_custom_data_value'] == $cart_item_key )

        print_r($woocommerce->cart->cart_contents[ $key ]);
        //unset( $woocommerce->cart->cart_contents[ $key ] );
    }


  }

}

请尝试以下代码：

add_action('woocommerce_before_cart_item_quantity_zero','wdm_remove_user_custom_data_options_from_cart',1,1);
if(!function_exists('wdm_remove_user_custom_data_options_from_cart'))
{ 
    function wdm_remove_user_custom_data_options_from_cart($cart_item_key)
    { 
        global $woocommerce;
        // Get cart
        $cart = $woocommerce->cart->get_cart();
        // For each item in cart, if item is upsell of deleted product, delete it
        foreach( $cart as $key => $values)
        {  
            if ( $_REQUEST['remove_item'] == $key )
            { 
                unset( $woocommerce->cart->cart_contents[ $key ] );
            }
        } 
    }
}
