Custom Libraries in code igniter and config files?

I have a library in code igniter that looks like class MyClass($options = array())

The file is Myclass.php

I have a file (config/Myclass.php) that looks like

$Myclass = array(
  'something' => 'value',
  'another'   => 'value'
);

Which I thought should pass the $Myclass array in when I initialize my class, but apparently not?

What do I need to do to fix it?

Fast-forward to 2013, someone is still having problems with this. So my situation was the same but slightly different, so I thought I'd try to save someone else some time.

  1. I was naming my config file after my extended class, that was wrong. The Config file should always be form_validation.php, (this is because eventually it is handed to the CI_Form_validation class and that's what it expects)

  2. Thanks to the folks who answered this question above, I realized that I had to pass the config to the parent class and using codeigniter v2.1.3 I did it as follows:

    public function __construct( $config = array() )
{
  parent::__construct($config);
}

AH I found the answer,

The array inside your config file must be called $config.

The name of the file must also be a lower case representation of the library file name.

e.g

LIB FILE: Somelibrary.php
LIB CONTENTS: class Somelibrary($options = array()){...
CONF FILE: somelibrary.php
CONF CONTENTS: $config = array('something' => 'value');

The way this usually works is that you pass in an array of options you wish to override, or pass in nothing to use the defaults.

var myObject = new MyClass(); // default settings

var myObject = new MyClass(array('something' => 'value2')); // override only "something"

Honestly, I wouldn't create your own file in config without a good reason; instead, just put the defaults in your class definition, and then override in your constructor:

class MyClass {

    var $default_options = array(
        'something' => 'value',
        'another' => 'value',
    );
    var $options = array();

    function MyClass($override_options = array())
    {
        $this->options = array_merge($this->default_options, $override_options);

        // your code here...
    }
}
