Sessions 2

[Nico]

Hello,

I tried to upload in my website the following trial php file:

<FORM METHOD="POST" ACTION="prova.php">
<b>Combination</b><br><br>
Element 1: <INPUT NAME="el1" TYPE="TEXT">
<BR>
Element 2: <INPUT NAME="el2" TYPE="TEXT">
<br>
<INPUT TYPE="SUBMIT" VALUE"Submit">
</FORM>
<br>
Combination<br><br>
<?php

session_start();
$_SESSION["combinations"][] = ($_REQUEST["el1"].$_REQUEST["el2"]);
print_r($_SESSION["combinations"]);
?>

As result, I obtain the following error:

Warning: session_start() [function.session-start]: Cannot send session
cookie - headers already sent by (output started at
/home/httpd/docs/prova.php:12) in /home/httpd/docs/prova.php on line 13

Warning: session_start() [function.session-start]: Cannot send session
cache limiter - headers already sent (output started at
/home/httpd/docs/prova.php:12) in /home/httpd/docs/prova.php on line 13

Sessions don't work.
Can you help me to understand which is the problem and how can I solve
it please?
Many thanks.

Cheers,
Nico

hello nico,

this error comes when you send anything to browser before starting
session. this happens with any header function you may use. to solve
this you must put "session_start()" at the start of php the page as i
had shown you in your the previous post.

this will solve your problem.

cheers
