Warning: session_start() [function.session-start]:

mark3mark

hi guys
Im really new to php.
Im trying to apply a dreamweaver template to a php file and when i upload it im getting this error
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/.goustav/xlsdemo48/demo48.xlswebstore.com/index.php:112) in /home/.goustav/xlsdemo48/demo48.xlswebstore.com/xls_functions.php on line 42

now Im applying the template to the php file because it is a supplied file from our point of sale system Xsilva lightspeed WEBSTORE (xsilva.com)
now am I getting this error because the template is putting code before the php?

any help would be great!!!

cheers

Hi Mark

You're right, the template must be setting something that prevents the session starting. Either set the auto session value to true in the php.ini file or alter the template and put the session_start() at the top of the page

Hope this helps
Tim

hey tim

cheers
and thanks for your reply

I am having the samae issue. What do you mean by having the start session at the top? I am using Dreamweaver and have other items, such as the include file for the DB connection at the top. Each page calls the session and checks if the user is logged in, proper admin level, etc. If I simply hit refresh, the error goes away and everything is fine. I'd just like to get rid of this error popping up altogether. I don't have access to my php.ini file, so what specifically would I tell my administrator to check?

messels

session_start () must be the first thing on your page before anything--including white space.

<?php
session_start ();

I have used session_start() at start but i'm reciving above eroor.
can any one give me code for online order.i'm very pleased with this and thanks very much.

messels

is that your code still?

are you only starting the session when "mysql_connect.php" is called?

that's what it looks like. i don't see session_start(); anywhere...

so, just to make sure. on the page you included.

first line. first word shoudl be:
<?php
//then followed by
session_start();
?>
BLAHABLAHABLAH
BLAHABLAHABLAH
BLAHABLAHABLAH

from what i understand, you have to start the session before your include tries to start it...

messels

check it.

before ANYTHING ON THE PAGE:
<?php
session_start();
?>

your code should then read:

<?php
session_start();
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Add a Product</title>
</head>

starting the session in the body is too late. good luck! 🆒
