The $r / $_REQUEST Shortcut
Each web application built with the framework has its own paths.inc.php file for setting up common variables and paths for the application.
paths.inc.php should be the first include in any application script. One of the roles it performs is to alias the $_REQUEST global variable. A copy of this variable is created and named $r. This is for the sake of pith and saves typing as much as anything else.
$r is used quite extensively in the SQL functions. Elements in application web forms should be named the same as their corresponding DB columns. That way the $_REQUEST/$r hash can then be passed to the SQL functions to do quick and easy inserts and updates such as in the example below for adding a new user:
$userid = add_new_row('user');
$r['user_password'] = sha1($r['user_password']);
$reply = update_table('user', $r, $userid);
