添加数据后数据库里什么都没有
include("conn.php");
 if(isset($_POST['submit'])&&$_POST['submit'])  
{
echo $sql="insert into message (id,user,title,content,lastdata)".
"values('','$_POST[user]','$_POST[title]','$_POST[content]',now())";
mysql_query($sql);
echo "发表成功";
}
?>

------解决方案--------------------
mysql_query($sql) or die(mysql_error());
------解决方案--------------------
不管mysql_query()是否真的成功,都会echo "发表成功"
------解决方案--------------------
把错误打开吧,这样可以根据错误提示做判断,这么看 代码似乎没有问题。但不代表include 部分是正常的
------解决方案--------------------
用手工操作一下sql 语句添加内容试一下。再说。
