WRITE DOORS:

Instructions:

1. if (pcbdoor_mode()) { surrounds the door }       : this makes the door inaccessible from outside
2. make your vars global to access them
3. return from your door with pcbdoor_return();
4. INSTEAD OF echo() U HAVE TO USE buf_put()


A readable skeleton:

<?
if (pcbdoor_mode()) {

    // your door is wrapped so make em global
    global $continue_door, $door_return; // your two buttons in this pseudo code
    
    if ($door_return) { // door_return button pressed
	// the return function HAS TO BE CALLED where you leave the door then i call pcboard and your door is over else i call and call the door
	pcbdoor_return();

    } else { 
      // pseudo code programm: a simple loop until door_return button pressed
      if ($continue_door) buf_put("called the door again!");

      // buf_form_header takes away the work to use pcboard.php and the correct ids
      buf_form_header(); 
	  // form contents
	  // assume for this pseudo code on field is for $continue_door
          // and the door jumps back into this form
	  // and another is for $door_return and if hit then we return back to pcboard and call pcbdoor_return() as the last function your code executes then to return to pcboard afterwards
      buf_form_footer();

    }      

}
