本人在开发中碰到的问题就是php insert 到数据库时insert不成功也不报任何错误。真是崩溃!

原始代码

 代码如下 复制代码

$sql="INSERT INTO `message` (`id`, `user`, `title`, `content`, `lastdate`) VALUES ('', '$_POST[user]', '$_POST[title]', '$_POST[content]', 'now()')";
_query($sql);


修改后代码

 代码如下 复制代码

$sql="INSERT INTO `message` (`user`, `title`, `content`, `lastdate`) VALUES ( '$_POST[user]', '$_POST[title]', '$_POST[content]', 'now()')";
mysql_query($sql);

去掉id,因为id是自动插入,所以去掉,这样就OK了!

如果字段是tinyint,int, ...类型的要么自动插入,要么给默认值,不要`id` values('')这样的空值,因为每个mysql版本不一样,会出现问题而找不出原因。
