redirect page

[Celina]

i am writing a page which only a register user can perform the function. the login script is already exist.

The original logic:
1. login page
2. login page call another program to validate. if login successful, redirect to page A else redirect to the login page.

Now i add a new page which require user login first before peform the function.
1. go to new page (eg. page 😎 and select function.
2. if user not login, redirect to login page.
3. if login successul, it will redirect to page A.

how can i redirect back to the calling page (Page 😎 after a successful login. at the same time, i need to preserve the redirect to page A if the login is not trigger by Page B.

thank you.

That almost didn't make alot of sense...maybe I'm just thick skulled though 😃

What I got from your post is that you want anyone (registered or unregistered) to use your handy-dandy little function (or service) on page B, but you want to make sure they're logged in or no handy-dandy function. Am I on to something here?? If they're not logged in, you want it to prompt them for a username and password and then remember where they were headed basically.

Sessions are your friend then!!!

Set two session variables:

1. Set $_SESSION["autheticated"] (or whatever you want to call it.) to test if the user is logged in.

2. Set $_SESSION["current_page"] (or whatever you want to call it.) to test what page the user was last accessing.

$autheticated will be set to true when the user successfully provides a valid username and password.

$current_page can be set to $_SERVER["PHP_SELF"] Just make sure you don't set this varibale in your login page(s).

So once a user submits the "handy-dandy little function" request, check to see if $SESSION["$autheticated"] is set to true, if not redirect via Header() to login page, if credentials match, redirect to $SESSION["current_page"]

Have fun!!
