Mobile devices and PHP sessions

toastyman · 9 Mar 2006 at 15:03

Hi all,

Does anyone know if mobile devices support PHP sessions?

This is how i'm declaring the pages:

Code:

<?php
session_name('HikingID'); session_start();
?>

I know the sessions work etc, as i've been testing in FF. As soon as I try it on the Openwave Simulator, none of my session variables are working. Is this problem to do with passing the Session ID? Should it be passed in the URL?

Cheers,
Rich

shouldnt be a problem as php goes through a parser and generates a html output, i know it works on my windows mobile, used to post here on it

Hmm not sure what's going on here then.
This is the first part of my page:

Code:

<?php
session_name('HikingID'); session_start();
$ses_id = session_id();
include("../includes/query.inc.php");
?>
<!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>ERH</title>
</head>

<body>
<?php
echo strtotime('9th March 2006');
$query = "SELECT * FROM hiking_hikedetails WHERE (`hiking_hikedetails`.`userid` = '{$_SESSION["user_id"]}') ORDER BY `hiking_hikedetails`.`hikeid` ASC";
echo $query;

The value of $query is

Code:

SELECT * FROM hiking_hikedetails WHERE (`hiking_hikedetails`.`userid` = '') ORDER BY `hiking_hikedetails`.`hikeid` ASC

When it should be

Code:

SELECT * FROM hiking_hikedetails WHERE (`hiking_hikedetails`.`userid` = '1') ORDER BY `hiking_hikedetails`.`hikeid` ASC

Anyone got any ideas for debugging etc?

I've found the problem but not sure what to do about it.

On the first page, the session id is set as 30c161aec5e60807ee1baf4d00cd339e, and then php forwards to http://localhost:8081/mobile/loggedin.php?30c161aec5e60807ee1baf4d00cd339e

However, on this next page, by echoing the session id, it has now changed to 05601cfaedc274ffdf42d602e422fb5d.

Any ideas on how to make it use that first one? Am I passing it in the URL incorrectly?

Bump - sorry, just hoping someone has an idea of the problem as I need to solve this before I can progress

The only issues you will experience with sessions are the client/user agents ability to store the session ID, namely in cookies.

It's possible to use GET vars to transfer the session ID between requests, but some user agents may be limited in the length of the query string.

Ah I solved it with that bit of help

I used GET to pass the session id, which was incorrectly named. All works now and I have a nice mobile site

Cheers
