Please help!

I am creating a web site with session control, I log the user in and register their username as a session variable then I use this variable to read from a database. Most of my scripts work perfectly except one called update.php. When I try and read the username session variable within this script it fails to work. I have tried running it locally on my apache server and it works, but fails to work on my hosting space. I really can't understand why!

Thanks,

Mike

Make sure your session save paths are correct in your php.ini on your hosted server.

Some little questions: Have you accidentally included the dollar sign? I ask because I did the same thing and it drove me crazy.

Adding to that, I meant to ask if you included it in your session_register function.

I did not include a dollar sign when I registered the variable, i know it has registered as it works in all my other scripts. I have even tried copying the initial code from my other, working scripts to no avail. Here is a snippet of code from the "non-working" script:

<?
session_start();
?>

<?
//connects to database here, all works.

$result = mysql_query("select * FROM users WHERE Username = '$valid_user'");
$array = mysql_fetch_array($result);
?>

If i replace $valid_user with an actual username the script works.
So i know that the session variable is not working properly, but it is in other scripts using identical code!

just thinking....are you using session_register or the global array $_SESSION ?

Does the username have an apostrophe in it....you may need to addslashes or mysql_escape_string to the username to see if it works. Also, what is the error you get (php and/or mysql)?

miztas

I use session_register to register variable, the username doesnt have an apostrophe as it appears in other scripts when I use the global variable. I don't know whether it could be something to do with the host...?
