In need of help.

[unsider]

Ok, I have been attempting to do a pretty simple task for the last little while, and unfortunately I've failed miserably.

 

I am trying to:

 

Establish the main section of website: index.php

 

I need a registration page: register.php

 

I need a login script that process my login info: login.php

 

I need a script that destroys existinging mess: logout.php

 

register.php (register with forms, no problem inputing into DB), if successful redirect to:

index.php (contains log in forms, enter info, action="login.php")

login.php(process the information, and if successful redirect back to index.php)

With a message displaying you are logged in, giving you the option to log out. (logout is pressed, redirected to logout.php)

logout.php then once destroying redirects once again to index.php with everything cleared displaying you are no longer logged in.

 

I have tried, but I've failed, here are the scripts I've been using, please feel free to edit so they are efficent, and work correctly.

 

Note: database contains: id, username, password, email. The include file is the db connect, so don't worry about any of that.

 

If you have the time to help a poor soul out, I'd much appreciate it. Thanks.

 

index.php

and the problem is??? 

[unsider]

I changed back to the scripts that functioned propery.

 

registration->login->index->logout->login

 

but unfortunately that's not what i wanted, and im not sure how to change it to function properly.

[cooldude832]

not functioning properly isn't very clear and no one gonna read through it for you if u don't clarify the issue

[mariocesar]

I have tried, but I've failed, here are the scripts I've been using, please feel free to edit so they are efficent, and work correctly.

logout.php then once destroying redirects once again to index.php with everything cleared displaying you are no longer logged in.

 

That's my problem, thats what I'm attempting to do. Sorry if I wasn't clear enough, hard to ask a question when the scripts work, but not the way i want them too 

[cooldude832]

so what goes wrong then or have u not tried it assuming it goes wrong.  Do pigs start flying out of your monitor when u run it? 

[unsider]

When I tried to change it to the functionality I wanted I ended up having problems trying to redirect back to the index.php without any errors. I wish I would have saved some of the errors, but basically it did not follow the path I would have liked.

 

I'm just seeing if I need to clarify more things, do you know what I'm trying to accomplish?

[unsider]

I know it takes time, but I'd really appreciate the help. I need it.

[cooldude832]

well if you can't articulate the "errors" to us I guess you can't be helped.
