If I view my script Opera and Firefox, I am having some various problems that don't exist in IE6 or IE7, and I think they may be due to the way that Firefox and Opera handle cookies, but I'm not sure. If anyone can look at my script at tell me if there are some problems I'd appreciate it. BTW, php.ini is set for session.use_trans_sid=1. Thank you.

I didn't look through all that code, however, I see a problem with this command:

 

session_name(bookstoreID);

 

If bookstoreID is defined as a constant with an alphanumeric value, then it's fine. Or maybe you meant to have it as:

 

session_name('bookstoreID'); // The session name is missing quotes around it

 

If bookstoreID is a constant and defined as just a numeric value, then that won't work. See warning on this page:

 

http://us2.php.net/manual/en/function.session-name.php

After changing it to include quotes, did you remember to delete all the cookies before testing again?

 

You have to change it to include quotes in all the PHP pages where it has a session_start().

 

If you're using sessions to hold shopping cart type of stuff, why have the session cookie stick around for so long (7 days)?

 

Anyway, you need to start putting echo to help yourself debug this. Display all the session data at the top of your script. i.e.:

 

echo '<pre>', print_r($_SESSION, TRUE), '</pre>';

 

If the session data displays as you expect, then the session is being saved and everything is fine on the PHP side and it's probably a bug in your logic/code.

I did delete the cookie before retesting. I have the shopping cart cookie info set to expire in 7 days because that is how long the cart exists on the Amazon server unless modified. I have been using print_r, and the actual cookie array is there... so I guess it may not be the cookie, but because the script works fine in IE, but not firefox or opera, I was assuming that the problem had to be something related to client side.

This thread is more than a year old. Please don't revive it unless you have something important to add.
