Can a submit button be a session variable?

Gary

Is there a way to make a submit button a session variable.

The submit button is in a function in an include file being called by index.php

The submit button has the name 'Login'

If it can't be a session variable, can it be a global variable?

I need the index page to call the login function if the visitor is not logged in...otherwise, I need to know the submit button was hit so I can keep track of the username, password, etc within the functions form fields.

Thanks so much

The submit button's value will be set in the global variable $POST['name_of_submit'] or $GET['name_of_submit'] depending on the METHOD used in the form.

(for earlier versions of PHP, try using $HTTP_POST_VARS or $HTTP_GET_VARS)

Thank you Jamie.

Does this mean that if I want to check to see that a submit button from a form in a function in an included file has been hit, I'd have to use something like:

if (!isset($_POST['Login'])) {

} else {

       print ("You are logged in".$_SESSION['username']);

}

The if else statement is in index.php....index.php includes functions.php....functions.php has the login() function.

Once submit is hit, and the username is verified, I'd like to display the message rather than the login form again.

Where I'm really confused is:
Do I have to start a session in the function itself in order to keep track of username, password etc?

Or, since there is a session started at the top of index.php and everything else is include files, will all the included files inherit the session_start() call?

Thanks again

yes, once a session_start() is called, everything run from then on has access to ANY session variables, because in effect when you include() another file, its contents are being run as though they were in the 'including' file.
