Hey guys... OK, heres the scenario:

You have a session when you log in
You have a $_GET['user']

You need to combine the 2... If your not logged in say you need to log in, if you select a user show that information, and if the $_GET['user'] is blank, only show that user (who is logged in)'s profile!

If you need code just ask!

Cheers in advance

PHP Code:

if (!isset($_SESSION['userid'])) {
   // you must login
}
else {
   if (isset($_GET['user'])) {
      // display selected user
   }
   else {
      // display user who is currently logged in
   }
} 


Correct?

What does the isset function do? Here the code i have (it doesn't include the login thing at the moment, hopefully going to add that as soon as I know how!)

isset() checks to see if a variable is set:

PHP Code:

 
 echo isset($foo); //false
 
 $foo = 42;
 
 echo isset($foo); //true
 
 unset($foo);
 
  echo isset($foo); //false 


It's main use is to check if there are any POST or GET variables that have been submitted, since on self submitting pages there may or may not be.

OK great, once again, thanks 0beron and other peeps! Hopefully get it sorted now! Thanks!
