[SOLVED] PHP sessions problem

kourosh · 2010-04-14 00:27:06

Since I don't often visit any other forum, someone here might be able to help

I have a *very* basic web 'application' written which uses PHP sessions. For some reason, the session variable only exists in one page. Change to another and it disappears. Surely session variables are suppose to avoid this problem?

Maybe I've got something entirely wrong. Any idea?

Can you post some sample code?

Well I've done a basic test:
test.php

<?php
session_save_path("/home/a7049782/public_html/films/tmp");
session_start();
$session_path = session_save_path();
$_SESSION['count']=1;
?>
<html>
<body>
<?php echo "Count=" . $_SESSION['count']; ?>
</body>
</html>

This sucessfully outputs 1

Then another page:
test2.php

<?php
if(isset($_SESSION['count']))
echo "Count=" . $_SESSION['count'];
else
echo "No variable.";
?>

Which outputs 'No variable.'

(I've also tried this without defining a path, still the same result)

You need:

session_start();

In the test2.php page before you use any session variables. For example:

<?php
session_start();
if(isset($_SESSION['count']))
echo "Count=" . $_SESSION['count'];
else
echo "No variable.";
?>

Right, I tried that, doesnt work :S

I thought I would only need to start the session once, and by setting a variable in test.php, that I would be able to access it in test2.php too?

Or have I got this entirely wrong?

You need the two session_start() statements. Perhaps the problem is with the cache of the browser. Also you can check a similar example in the Official Php page (Example #1 and #2).

Thank you!
I removed the save paths and w/e to use defaults again and it worked.
Thanks again, this has been annoying me for weeks
