if(isset($_POST['submit']))无法执行
<form name="adduser" action="dealadduser.php" method="POST">
添加管理员<br>
姓 名： <input type="text" name="username"></br>
密 码： <input type="password" name="password"></br>
<input type="submit" name="submit" value="提交"/>
<input type="reset">

</form>

<?php

if(isset($_POST['submit']))
{

mysql_connect("localhost","root","");
mysql_select_db("soft");
mysql_query("set character set gbk");
$username=$_POST["username"];
$password=$_POST["password"];
$sql="insert into `users`(`name`,`pass`) values ('$username','$password')";
echo $sql;
mysql_query($sql);
mysql_close();

}
?>



点提交一直无法写入数据库，if(isset($_POST['submit']))根本不执行？求教

[解决办法]
测试过你的代码是没有问题的，除非你这个页不是dealadduser.php

PHP code

<form name="adduser" action="" method="POST">//如1楼说的直接本页  添加管理员<br>  姓 名： <input type="text" name="username"></br>  密 码： <input type="password" name="password"></br>  <input type="submit" name="submit" value="提交"/>  <input type="reset"></form><?phpif(isset($_POST['submit']))  {      mysql_connect("localhost","root","");  mysql_select_db("soft");  mysql_query("set character set gbk");  $username=$_POST["username"];  $password=$_POST["password"];  $sql="insert into `users`(`name`,`pass`) values ('$username','$password')";  echo $sql;  mysql_query($sql);     mysql_close();     }?>

难道你的本页不是dealadduser.php页吗？
如果不是，dealadduser.php页应该是
PHP code
<?phpif(isset($_POST['submit']))  {      mysql_connect("localhost","root","");  mysql_select_db("soft");  mysql_query("set character set gbk");  $username=$_POST["username"];  $password=$_POST["password"];  $sql="insert into `users`(`name`,`pass`) values ('$username','$password')";  echo $sql;  mysql_query($sql);     mysql_close();     }?>
