我正在使用WP_List_Table 类和我为以下操作添加了链接：

function get_bulk_actions() {
        $actions = array();

        $actions[\'approv\'] =\'<a href="#">\'.__( \'Approve\' ).\'</a>\';
                $actions[\'reject\'] = \'<a href="#">\'.__( \'Reject\' ).\'</a>\';
                $actions[\'delete\'] = \'<a href="#">\'.__( \'Delete\' ).\'</a>\';
                $actions[\'view\'] = \'<a href="#">\'.__( \'View\' ).\'</a>\';


        return $actions;
    }

然后我在display_row() 功能如下：

$actions = $this->get_bulk_actions();
echo $this->row_actions( $actions );

现在我想知道如何将自定义操作添加到我创建的链接中。是否有任何地方可以将变量发送到页面？要对这些链接进行DB处理并重新填充WP_List_Table 这是在我执行操作之前创建的。
