how do i call this?

[djcritch]

Hi i have set up a php session using GET but having a bit of trouble calling the information, can anyone see what im doing wrong?

 

heres what ive got:

 

session_start();
foreach ($_GET as $key => $value)
{
  $_SESSION[$key] = $value;
}

 

and to call it i have:

 

<?php $_SESSION['url'] echo $_value; ?>

 

but im guessing this is incorrect ?

im guessing when you run that FOREACH loop, 'URL' is what is being passed over as the name of the session.

 

You then store the Data in the session.

 

So I think you would need: -

 

 <?php echo $_SESSION['url']; ?>

 

Im not too sure what your trying to acheive with the code though so I'm not sure this is what you want. Also, if the $_GET fails, then there is no data to be stored in the session, so there would be no data to output.

yea i have a form that goes to a.php which contains the session code but i then want to call it b.php and c.php

 

but

 

<?php echo $_SESSION['url']; ?>

 

doesnt do the job cant understand why not?

depending on your installation you need a "session_start()" at the top of each script using sessions.

 

also depending on your installation you may need to pass a query string between pages that use sessions eg:

 

www.url.com/index.php?PHPSESSID=3ui92grubf23yfgw34r

 

the phpsessid is recognized by session_start(),

ok thanks got it working now but getting this error message above it:

 

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

 

any idea why?

session_start(); has to be put before any input.. all the way at the top of all your codes and HTML etc
