Creating a First Login

[iSlayer]

Well I posted a thread a while back about function firstLogin(pl) but i was told that theres no inbuilt command for it so I made this script

PHP Code:

function onPlayerOnline() {
  if(clientr.firstlogin = true) {
    clientr.firstlogin = false;
    // Adds all the default flags
  } else {
    destroy();
  }
} 


Will this work correctly? And if not how can i improve it
