$conn = @MysqL_connect("localhost","root","") or die("数据库连接出错!");
MysqL_select_db("gb",$conn);
MysqL_query("set names 'GBK'");
?>

add.PHP

代码如下:

PHP
include("config.PHP");
if($_POST['submit']){
//在这里的时候，忘记message里还有个字段lastdate没有写,导致插入数据不成功。找了好久才找出错误。
$sql="insert into message (id,user,title,content,lastdate) values ('','$_POST[user]','$_POST[title]','$_POST[content]',Now())";
MysqL_query($sql);
echo "成功";
}
?>
