You mean you have to write your own code to get your application going? How quaint! How so-o-o-o last century! All 2,500 user transactions in my application are started from a script such as this:
<?php
$table_id = "person"; // identify the Model
$screen = 'person.detail.screen.inc'; // identify the View
require 'std.enquire1.inc'; // activate the Controller
?>
And guess what? Each of these scripts is generated by the framework from a GUI screen. The Controller scripts are part of the framework, and each Model class is generated by the framework from another GUI screen. The $screen script specifies which XSL stylesheet will be used by the standard View component. This is how I can generate the code for a user transaction, and run it immediately from an online menu, without having to write a single line of code - no PHP, no HTML, no SQL. This transaction will automatically include all default behaviour, and the developer only has to write code when he wants to alter this behaviour.
