我試圖在 Wordpress 類中調用這個 add_filter 。我遵守了所有規則，但由于某種原因，它不起作用。class WoocommerceController extends BaseController{function register(){ add_filter('woocommerce_thankyou_order_received_text', array($this, 'woo_change_order_received_text', 10, 2 )); }function woo_change_order_received_text( $str, $order ) { $new_str = $str . ' We have emailed the purchase receipt to you.'; return $new_str; }}

您在數組中傳遞優先級和參數，這就是它不起作用的原因 add_filter('woocommerce_thankyou_order_received_text', array($this, 'woo_change_order_received_text'), 10, 2 ) 像這樣寫
