[SOLVED] Session Problem

[ballouta]

Hi

It is my first session test. Everything was working properly as expected, I took a break and now the same pages and the same code is not working, i couldn't discover where the problem exists.

 

here's the session code from the first page:

<?php
session_start();
$user=$_POST['user'];
$pass=$_POST['pass'];

$_SESSION['username'] = "$user";
echo $_SESSION['username'];
?>

 

i am able to see the username after the echo command. in this page i do not have any problem.

 

Page 2:

 

<?php

@session_start();
include('CMS/global.inc.php');
$user =$_SESSION['username'];
echo "User = $user";

if($_SESSION['username']) {

here i have some DB code
}
else
{
echo "session not working";
}

 

I cant see the user echoed here and 'session not working' appears.

where's the problem?

please help

Did you close the browser window between the first test and the second test? Closing the browser window deletes the current session. Also, how do you get from the first script to the second?

If you have already set $_SESSION['username'] you don't need this:

 

$user = $_SESSION['username'];

 

you can just do this:

 

echo 'User: ' . $_SESSION['username'];

 

and like the guy above me says, if you closed the browser window your session data is gone

also remove the @ from session_start(); as this stops errors appearing( i think, correct me if i'm wrong)

<?php

session_start();

thank you all

 

First, I didn't close the explorer while making my test.

Second, I removed that @ and I got this warning:

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output

started at /home/ballouta/public_html/login.php:7) in /home/ballouta/public_html/login.php on line 28

 

Third, in page2.php I got this warning too:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/ballouta/public_html/credits.php:7) in /home/ballouta/public_html/credits.php on line 38

 

Note: I just tested the pages again and the result (except the warnings) is correct,

BUT when i upload page1.php and page2.php to another host, it is not working.

 

How do I fix the problem mentioned in the warning so i can get to the secnd part?

How do I fix the problem mentioned in the warning

Simple, read the warning messages and find what the output is that they are telling you is occurring in each of the files -

 

output started at ..../login.php:7 (line 7)

 

output started at ..../credits.php:7 (line 7)

I already did, I had a look on line 7 which is:

<link href="layout.css" rel="stylesheet" type="text/css" />

 

but i don't know if there's any conflict between css and sessions!

ob_start() will solve it but it is only a hack not a solution 

[ballouta]

do i have to add this 'hack' after starting the session, actually never heard about this

thanks

[darkfreaks]

actually you declare output buffering before session start it will clear up those errors. but if you turn error reporting on thery will come back 

[PFMaBiSmAd]

Any page that uses a session should have the session_start() statement at the very beginning of the page. You are putting a session_start() at lines 28/38 in your two files.
