sessions help

Anon

I’m in the process of writing a website for the popular mount snow yahoo club (http://clubs.yahoo.com/clubs/mountsnow). I finished the signup form, mysql backend, forum, login, etc. and wanted to test it out on a free host before I finished the rest of the code and eventually bought some space to host it. Any way it worked on my windows 2k box and Linux box flawlessly but when i uploaded to host.sk the problems began. Most on the initial problems dealt with database issues, which i resolved then the signup form didn't work (i fixed that too) but now when a user tries to login the login itself works but it won't let me start a session. Here’s the error message:

Warning: Cannot send session cookie - headers already sent by (output started at /mnt/host-users/mountsnow/login.php:2) in /mnt/host-users/mountsnow/login.php on line 59

Warning: Cannot send session cache limiter - headers already sent (output started at /mnt/host-users/mountsnow/login.php:2) in /mnt/host-users/mountsnow/login.php on line 59

That’s really all I can say except that to see the php source of the page point your browser to

http://mountsnow.host.sk/showsource.php?name=/login.php --or what ever page you want to see

You have some whitespace before you send the session_start. Thats what it always is.

I'd agree with Fitz, but to make it more broad, any time you send header information (session cookies) you must first make sure that you have not sent any data to the user yet, As Fitz was saying it is VERY common for somone to leave whitespace at the top of their document, the way to solve this is to make sure that the <? OR <?PHP OR <script language=PHP> is on the first line of code without any spaces before it.

I'm getting a similar problem.

How many times do I have to call session_start()?
I have it on my login script at the top and it works perfect....then i have it on my main page to show your stats (username etc) and it gives me:
Warning: Cannot send session cache limiter - headers already sent (output started at /user14/user19/darksto6/index.php:6) in /user14/user19/darksto6/header.php on line 2

this is my script up to line 6:
<?php
session_start();

print ("
<head></head>
<body bgcolor=\"#000000\" text=\"#ffffff\">");

Try just <? session_start() ?>

I bet you have some whitespace after the '<?php' on your first line.

i dont think i'm leaving any white space... look at the code :

http://mountsnow.host.sk/showsource.php?name=/login.php
