<?php

// We use this same text file for editing a user's details (both THEUSER's and
// a different user's), and letting a new user join.
// This means we can keep all the form validation and display code in one place.

/* What happens?

	1) We check what $this_page is going to be. This depends on:
		* the value of $pg, if anything;
		* whether $THEUSER is logged in or not;
		* whether $THEUSER has appropriate security privileges;
		* and whether we've been passed the ID of a user to view/edit.
	
	2) If we've come to this page after submitting its form, we check the form data.
		If the data is OK, we either edit or add the user and display the new info.
		If there were errors, the same form is displayed again with error messages.
	
	3) On the other hand, if the form hasn't been submitted we've just arrived here.
		In that case the form (or the user info, if just viewing) is displayed.
		
		
	After the first part of working out which page we're on, and munging any data
		various functions in this file are used:
		
		check_input()	Validates the edited or added user data and creates error messages.
		add_user()		Calls $THEUSER->add() and displays the results, depending on success.
		update_user()	Calls the appropriate functions and updates, displays results.
		display_form()	Displays the form for editing or adding a user.
		display_user()	Displays a user's details.
