undefined issue

Question

Hey everyone,

I recently make a simple test site on my local server to login as an admin and redirect to an admin based page as well as to log in as a user for the regular user page..When I made the test site..it seems to work fine but when I put it on the site that actually needs to go on the web..it doesn't work..it says that I have multiple undefined errors..and I'm not sure why because when I echo out what I sent from the form..the data shows, including whether or not the submit button has been submitted..I'm at a loss..

Here are the errors

"Notice: Undefined index: username in C:\Program Files (x86)\EasyPHP-5.3.8.1\www\Test\index.php on line 3

Notice: Undefined index: password in C:\Program Files (x86)\EasyPHP-5.3.8.1\www\Test\index.php on line 4

Notice: Undefined index: Submit in C:\Program Files (x86)\EasyPHP-5.3.8.1\www\Test\index.php on line 9"

here is the index.php(which includes a login section starting at line 109)

<?php

$user = $_POST['username'];
$pass = $_POST['password'];

mysql_connect("*********","*****","********");
mysql_select_db("********");

if($_POST['Submit']){
$select = "SELECT * FROM USERS where username='".$_SESSION['$user']."' && password='".$_SESSION['$pass']."'";
$msq = mysql_query($select);
 if(mysql_num_rows($msq)>0)
    {
    while($row = mysql_fetch_array($msq))
          {
            $username = $row['username'];
			session_start();
            $_SESSION['username'] = $username;
            echo $_SESSION['username'];
            
            }
            header("location: checkuser.php");
   }}

try changing the top to this let me know how it goes
also if this is a login script i would say to validate the data
also session start should be on top no spaces

<?PHP
session_start();

if($_POST['Submit']){
$user = $_POST['username'];
$pass = $_POST['password'];
// validate the data
$user = stripslashes($user);
$pass = stripslashes($pass);
$user = mysql_real_escape_string($user);
$pass = mysql_real_escape_string($pass);
 
mysql_connect("*********","*****","********");
mysql_select_db("********");
$select = "SELECT * FROM USERS where username='".$_SESSION['$user']."' && password='".$_SESSION['$pass']."'";
$msq = mysql_query($select);
if(mysql_num_rows($msq)>0)
{
while($row = mysql_fetch_array($msq))
{
$username = $row['username'];

$_SESSION['username'] = $username;
echo $_SESSION['username'];
 
}
header("location: checkuser.php");
}}

well that took away the first set..now the only thing that's left is the submit button..

when I do an if/else statement and echo out if the button has been submitted or not and then get the message "your submit button has been pressed"..shouldn't that mean that it is working? if so then why do I get that error?

'Notice: Undefined index: Submit in C:\Program Files (x86)\EasyPHP-5.3.8.1\www\Test\index.php on line 4'

<form action="checkuser.php" method="post" name="" id="">
Username:<br />
<input size="10" type="text" name="username" id="username" /><br />
Password:<br />
<input size="10" type="password" name="password" id="password" /><br />
<input type="Submit" name="Submit" value="Submit">
</form>

so I fixed the submit issue..I needed to add "isset" to the post variable..but now when it submits..the checkuser.php shows up with a black page..and it doesn't redirect to the designated page depending on whether its an admin or a regular user..

checkuser.php

<?php
error_reporting (E_ALL ^ E_NOTICE);
?>
<?php
session_start();

//connect to db
$connect = mysql_connect("*********","*****","*******");
mysql_select_db("******");



$get = mysql_query("SELECT * FROM users WHERE username ='".$_SESSION['username']."'") or die(mysql_error());
while($row = mysql_fetch_array($get)) 
{
   $admin = $row['user_level'];
         if ($admin == 0)
         {
            header("Location: index.php");
         }
        elseif ($admin == 1) 
        {
           header("Location: Blog-admin-area.php");
        }
      else
      {
         echo "this is an invalid status";
         }
}
?>

why does this work with my test site and not this one?

probley diffrent versions of php and diffrent servers like lamp or wamp
also your $get variable

$select = "SELECT * FROM USERS where username='".$_SESSION['$user']."' && password='".$_SESSION['$pass']."'";

// i think before we were valiadating $user and $pass



$select = "SELECT * FROM USERS where username='".$user."' && password='".$pass."'";

or there is no user because we never set the session

geneh23 0 Junior Poster · Answer 5 · 2011-12-31T02:31:45+00:00

Should I replace my $select query with the second one you have without the session in front of the user and password for the index page?

and I'm using Easy PHP for my local server..EasyPHP-version 5.3.8.1

geneh23 0 Junior Poster · Answer 6 · 2011-12-31T04:08:11+00:00

well I guess this thread has been solved since the undefined errors are gone. I'll post another thread over this blank page that seems to show. Thanks!
