Question

我发现什么是错的。在第一次会议之后发生了一些事情。

'SELECT m1.id, m1.title, m1.timestamp, count(m2.id) AS reps, users.id AS userid, users.username FROM pm AS m1, pm AS m2,users WHERE ((m1.user1="'.$_SESSION['user'].'" AND m1.user1read="no" AND users.id=m1.user2) OR (m1.user2="'.$_SESSION['user'].'" AND m1.user2read="no" users.id=m1.user1)) AND m1.id2="1" AND m2.id=m1.id group by m1.id ORDER BY m1.id DESC');

Answer 1

你有＆＃39;在字符串的开头，也是AND m1.id2 =＆＃34; 1＆＃34;缺少开头的括号。另外，users.id来自哪里？

'SELECT m1.id, m1.title, m1.timestamp, count(m2.id) AS reps, users.id AS   
(
    (m1.user1="'.$_SESSION['user'].'" AND m1.user1read="no" AND users.id=m1.user2) 
    OR 
    (m1.user2="'.$_SESSION['user'].'" AND m1.user2read="no" users.id=m1.user1)
) 
AND m1.id2="1" AND m2.id=m1.id group by m1.id ORDER BY m1.id DESC');

无法找到线路的错误
