why doesn't it work?

Herr_Vredy

Hi,

i've written a login-script. It works fine, but just on one point there's still a problem.
You have to fill in your name in a textfield called $naam and your e-mailadress. When the button 'Register' is pressed (action=registreren), the script loads a file with all the users. Then it normally has to check if $naam wasn't already taken.
This is my code:

<?
		$naam_bezet = false;
		$userslist_array = file("textfiles/userslist.txt");
		$aantal_users = count($userslist_array);

	switch($action){
		case "":
			include('register.htm');

		case "registreren":{
			 if ($naam != '' and $mailadres != '') {

			//checking if $naam wasn't already taken


					for ($i = 0; $i < $aantal_users - 1; $i++) {
						$username = $userslist_array[$i];
						if ($username == $naam) {
								$naam_bezet = true;
								break;
							}
					}


					if($naam_bezet == false) { 
      //now the script writes the new user in the userslist.txt-file, that part of the script works, so I will not post it here
                                  }
             }
             else {
                    echo "This name is already taken";
            }
       }
       break;
   }
?>

For some reason, the script seems not to change $naam_bezet in true, even if you fill in a name that is in the userlist. Maybe it always sets $naam_bezet back on false for some reason?
I don't understand why it doesn't work.
Can anyone help me?

Thanks a lot,

Herr Vredy

I've found it myself.
I had to add the trim()-function to check the names.

Greetz,

Hey kjeldoran,

Next time start your own thread...

but your script works fine on my intranet server... I don't see why it doens't work for you. Maybe you have something setup wrong?
