所以我得出的结论是,这个错误是由于两行特定的代码造成的。

$notification_object->flag = true;
$notification_object->save();

似乎抛出:

SQLSTATE[08P01]: <<Unknown error>>: 7 ERROR:  bind message supplies 0 parameters, but prepared statement "pdo_stmt_0000000f" requires 1

有谁知道为什么?

根据要求提供更多信息

那么 $notifications_object 是如何创建的呢?

$notifications_table = new Users_Model_NotificationsMapper();
$notifications = $notifications_table->findByUserAndId($request, $identity->id);

然后我们循环遍历:

foreach($notifications as $notification_object){
    //Do some code

   //We need to now update a value in the database,
   //essentially in the row we just got back.

   $notifications_object->flag = true;
   $notifications_object->save();

}
