Session not being set

[papaface]

Hello,
My script works on everyones server so far except one person.
The sessions arent being set.
Is there anything I can add to the below code to set the session if $_SESSION["username"] and $_SESSION["password"] arent set?
[code]<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
require("../includes/checker.php");
require ('../includes/connect.php') ;
require ('../includes/checklogin.php') ;

if ($logged_in == 1)
{
echo "You are already logged in ".$_SESSION["username"];
echo "<br>" . '<a href="submissions.php">' . "Click here to view pending Link Exchanges" . "</a>";
echo "<br>" . '<a href="approved.php">' . "Click here to view approved(active) Link Exchanges" . "</a>";
echo "<br>" . '<a href="logout.php">' . "Click here to logout!" . "</a>";
exit;
}

if (isset($_POST["submit"]))
{
if(!$_POST["username"] | !$_POST["password"])
{
die("You did not enter the required fields");
}

$check = mysql_query("select username,password from users where username='".$_POST["username"]."'") or die ("error" . mysql_error());
list($username,$password) = mysql_fetch_array($check);

$_POST["username"] = stripslashes($_POST["username"]); //strip the slashes

if (!$_POST["username"] == $username)
{
echo "The username you entered does not exist";
exit;
}

$_POST["password"] = stripslashes($_POST["password"]); //strip the slashes

$encpass = md5($_POST["password"]);


if ($encpass != $password)
{
die("Sorry you entered the wrong password");
}
else
{

$_SESSION["username"] = $_POST["username"];
$_SESSION["password"] = $_POST["password"];

echo "You are now logged in " . $_SESSION["username"];
echo "<br>" . '<a href="submissions.php">' . "Click here to view pending Link Exchanges" . "</a>";
echo "<br>" . '<a href="approved.php">' . "Click here to view approved(active) Link Exchanges" . "</a>";
echo "<br>" . '<a href="logout.php">' . "Click here to logout!" . "</a>";
mysql_close($con);

}

}
else
{
echo '<table width="100%" height="100%" cellpadding="2" cellspacing="2" border="0">
<tr>
<td align="center" valign="middle">
<form action="'. $_SERVER['PHP_SELF'] .'" method="post" enctype="application/x-www-form-urlencoded">
Username: <input name="username" type="text" />

Password: <input name="password" type="password" />
<input name="submit" type="submit" value="Submit" />
</form>
</td>
</tr>
</table>';
}
?>[/code]

You need session_start(); at the top of your page.

I should have included the checklogin.php file:
[code]<?php

require ('connect.php') ;

session_start();

if (!isset($_SESSION["username"]) || !isset($_SESSION["password"]))
{
$logged_in = 0;
return;
}
else
{
$pass = mysql_query("select password from users where username='".$_SESSION['username']."'",$con);
list($password) = mysql_fetch_array($pass);

if(mysql_num_rows($pass) != 1)
{
$logged_in = 0;
unset($_SESSION['username']);
unset($_SESSION['password']);
}

if ($password = $_SESSION["password"])
{
$logged_in = 1;
}
else
{
$logged_in = 0;
unset($_SESSION['username']);
unset($_SESSION['password']);
}

}

?>[/code]

Please help  :(

Bump again

[papaface]

There must be someone that can help me :(

You need session_start() at the top of all pages using sessions. Your question was answered 3 bumps ago!

[papaface]

If you look checklogin.php is included on every page so session_start() is included on every page...

[Philip]

You could always try session_register(); before hand. Sometimes it helps.

What is that one person running? What PHP settings?

[ted_chou12]

oh, if you have another php page script, and it has session_start(); at the top, is requiring that php script at the top of the page okay?

Argh I must have changed something in one of these files because now it isnt working for me either on my localmachine, when it was working before.

[papaface]

Ah I have found the error:
was:
[code] $_SESSION["username"] = $_POST["username"];
$_SESSION["password"] = $_POST["password"][/code]
should have been:

[code] $_SESSION["username"] = $_POST["username"];
$_SESSION["password"] = $encpass;[/code]

Thanks for all of your help guys!

session_register() has long been depricated.
