我有两个Woocommerce支付网关类叫做＃34; WC_banklink_seb＆＃34;和＃34; WC_banklink_swedbank＆＃34;最后一个在将Woocommerce 2.2更新到2.4时停止工作
集成和付款仍然有效，但使用wc-api的返回网址却没有。
当我使用＆＃34; WC_banklink_swedbank＆＃34;支付网关并从支付提供商返回到网址http://my-domain.com/wc-api/WC_banklink_swedbank/我收到以下错误：
致命错误：第304行的/ wp-content / plugins / banklink_seb / banklink.php中的签名无效
班级＆＃34; WC_banklink_swedbank＆＃34; actualy位于文件夹... / wp-content / plugins / banklink_swedbank /
我的任务是为什么wc-api从另一个支付网关返回一个班级？类WC_banklink_seb和WC_banklink_swedbank之间唯一的共同点是它们都扩展了＆＃34; WC_Payment_Gateway＆＃34;
这两个代码都是来自类的appart和插件名称几乎相同，因为＆＃34;设置＆＃34;设置在adin面板上。
让我感到困惑的是，当我禁用该类的插件＆＃34; WC_banklink_seb＆＃34;时，＆＃34; WC_banklink_swedbank＆＃34;再次开始工作？

答案 0 :(得分：0)
问题列在动作名称“valid_request”中，并不是唯一的。两种付款方式都注册了相同的操作，因此只有第一个付款方式才真正注册。
add_action('valid_request', array($this, 'successful_request'));
应使用唯一名称替换操作的名称，例如：
add_action('valid_request_swedbank', array($this, 'successful_request'));
当然在相应的do_action（）
中更改操作名称do_action( "valid_request_swedbank", $_REQUEST );
