我在代码中标记了出现错误的地方,大概有7行。 我有另一个问题,但从来没有得到答案,基本上我试图让我的论坛,以便所有的子类别(论坛)进入类别,并不会每次都做一个全新的论坛div。查询内部查询是否可以显示这样的类别?

哪一条是错误信息?几乎可以肯定这是一个括号问题。 – jcoppens

几乎在任何时候你有嵌套查询,并且内部查询使用外部查询的值来进行'where'过滤,你可能应该/应该使用SINGLE'join'ed查询来重写。 –

看起来你没有用CATCH结束TRY块。 –

你还没有写出第二次尝试。所以代码将以等待捕获的错误结束。 以这种方式更改代码

} 
catch(PDOException $ex) { 
    die("error"); 
} 
} // Getting an error here!

我已经添加了它,但似乎我没有上传它。对不起,伙计,谢谢! –
