<p>Creating modules and add-ons</p>

Controllers

These are located in /core/modules. The basic format in a URL:

index.php/pilots

Maps to:

/core/modules/pilots/pilots.php

Additionally,

index.php/module_name/function_name/

When no function name is given, it defaults to the index() function. For example:

class ModuleTest extends CodonModule
{
public function index()
{
	echo "We are at index";
}

public function pageone()
{
	echo "We are at page one";
}
}

Going to:

 index.php/moduletest/pageone

Would output:

 We are at page one

This simplifies development

Passing Variables

Variables can be passed in several different ways. We'll use two different URLs and functions to demonstrate

 index.php/moduletest/pageone/apple/red

index.php/moduletest/pagetwo?fruit=apple&color=red

The code:

class ModuleTest extends CodonModule
{
public function pageone($fruit='', $orange='')
{
	echo "The fruit is an {$fruit} and the color is {$orange}";
}

public function pagetwo()
{
	echo "The fruit is an {$this->get->fruit} and the color is {$this->get->orange}";
}
}

As you can see, the "pageone" method is cleaner - the function parameters will be the variables after the function name in the URL, in the order they appear in the URL.

The "pagetwo" method is the more "traditional" way of doing things, but they are essentially the same thing. To access the variables in the query string you use:

$this->get->[variable name]
