I have confused for this login method, especially for different access page for some users after login.

I have some user list in my DB like:

  1. admin
  2. user

I want if I’m login as admin will direct to input.php and if I login as user will direct to index.php. i have read from some sites that it must use switch-case. But, I’m still unclear how to use that.

$dbc=mysql_connect(_SRV,_ACCID,_PWD) or die(_ERROR15.": ".mysql_error());
$db=mysql_select_db("qdbase",$dbc) or die(_ERROR17.": ".mysql_error());

switch(postVar('action')) {
        case 'submitlogin':
                submitlogin(postVar('loguser'),postVar('logpass'));
                mysql_close($dbc);
                exit;
                break;
}

function submitlogin($loguser,$logpass){
        if(isset($loguser,$logpass)){
                $myuser= mysql_real_escape_string($loguser);
                $mypass= mysql_real_escape_string($logpass);
                $sql= sprintf("SELECT * FROM admin WHERE user = '".$myuser."' AND password = '".$mypass."'", $myuser,$mypass);
                $result = mysql_result($sql) or die (_ERROR26.": ".mysql_error());
                if(mysql_num_rows($result) > 0){
                        session_register("loguser");
                        session_register("logpass");

      switch $myuser{                          //i dont know its correct or not
           case 'admin':
               header("location:input.php");
               break;
           case 'user':
               header("location:index.php");
               break;
           }    
?>

<?php
    }else
        {
            header("location:log.php?msg=" . urlencode("Wrong Username or Password. Please retry"));
       }
    }else{
       header("location:log.php?msg=" . urlencode("Please enter some username and password"));
    }
}
?>

i got this error:

PHP Warning:  mysql_result() expects at least 2 parameters, 1 given in /home/jeinqa/www/oqc/dolog.php on line 29 // on line 17 in this page

    If what you’re trying to do is to redirect user ‘admin’ to other after-login page, instead of

    header("location:index1.php");    //i want to use switch-case in this part

    you need something like

    switch($loguser) {
    case "admin" :
         header("location:input.php"); 
         break;
    default: // this branch will run for all users other than 'admin' 
         header("location:index.php"); 

}
