Hello You tutorial

Adding logic to your pages

This tutorial will start at the point the Hello World tutorial left off: with a single HTML page outputting the traditional phrase "Hello, World!". The Hello World tutorial's completed code is hosted at http://github.com/BrightFlair/hello-world-tutorial.

Page View & Page Logic

Pages that consist of HTML source (or other markup) are called Page Views, and strictly contain no PHP code.

Code that executes in context of a page is called Page Logic. To add Logic to a View, create a PHP script with the same name as the View. For example, the index.html view has its logic in the optional index.php script. The contents of the Logic script is a class definition with at least one method, go().

The go() method is called before the page is rendered and allows you to interact with the page via PHP and execute your required logic, calling other classes and functions where required.

The Page Logic's namespace is the Page directory prefixed with your application's namespace (by default, "App"). See below for an example.

Namespaces must be PSR-4 compliant.

The boilerplate Page Logic class for the index page looks like this:

src/page/index.php

<?php
namespace App\Page;

class Index extends \Gt\Page\Logic {

public function go() {
	// Your page logic here.
}

}#
