Hi,

Thank you ever so much, it has resolved the session.php, however and I'm sorry to burden this unto you. I can view the register.php form, once join is clicked, the following occurs : an error occurs in the avatar * 687202 is wrong extension">.

Further more It would say sign up success, only if I left the other fields empty and just added an avatar.

Register.php

Any time, I'm off Uni with the flu, so I playing around with the script. So it's not urgent what so ever.

I will let you know if I figured it out.

Thanks for all your help.

No not at all. I'm actually getting there in terms of fixing it. I see it as a challenge! I'm always logged on this site, a phase at the moment! :)

Hi all,

Please ignore my past prob, I have used the given code in a fresh copy of the Login system! And here are my new problems...

1. The system will not allow one to register by returning a register unsuccessful. But it makes a directory for the user in the avatar folder and also uploads pic.

2. However, in useredit.php one can upload pic and it will store it in the database and will store it in the avatar folder.

Hello,

Claudia when posting long codes like that try to use

[ /code]

remove the space's after the [
