插入序列化值时出现 Snytax 错误？

Question

我的代码：

 $meta_ar = array("event_id" =>  $event_id, "user_id" => $user_id, "dbe" => $dbe, "hbe" => $hbe, "forum_id" => 'dummy_forum');

        $meta_ar = serialize($meta_ar);

        $db->query_write("
            INSERT INTO " . TABLE_PREFIX . "event_mod 
                (event_meta)
            VALUES
                (" . $meta_ar . ")
        ");

错误：

Invalid SQL:

            INSERT INTO event_mod 
                (event_meta)
            VALUES


    (a:5:{s:8:"event_id";N;s:7:"user_id";s:1:"1";s:3:"dbe";i:45;s:3:"hbe";i:32;s:8:"forum_id";s:11:"dummy_forum";});

MySQL Error   : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ':5:{s:8:"event_id";N;s:7:"user_id";s:1:"1";s:3:"dbe";i:45;s:3:"hbe";i:32;s:8:"fo' at line 4
Error Number  : 1064

任何想法？

Answer 1

将其更改为使值括在单引号中。

当您将任何字符串传递给任何应该包含字符串值的列时，必须将其括在引号中。

 $db->query_write("
            INSERT INTO " . TABLE_PREFIX . "event_mod 
                (event_meta)
            VALUES
                ('" . $meta_ar . "')
        ");

Answer 2

使用PreparedStatement ，您的序列化数组不会被转义。
