It's not the 'correct' usage of helpers but no harm no foul. The documentation is a guideline for using the framework. You use the tools that are available to the best of your creativity

You can also load the class as a plugin, it will not be instaniated by CI

I personally see nothing wrong including them like this in a controller:
Code:
require_once(APPPATH.'libraries/Someclass.php');And them instantiate them using conventional PHP.

That was my second suggestion but meglio wants to do it CI wise i guess.

Hello,
that's really not a correct usage of helpers. I see two more elegant solutions :
Autoload your libraries with autoload functions
Perhaps you already know it, something like :
helpers/autoload_helper.php
Code:
function __autoload($class_name) {
if ( is_file(APPPATH.'/libraries/'.$class_name.'.php') ) {
require_once APPPATH.'/libraries/'.$class_name.'.php';
}
}And in config/autoload.php
Code:
$autoload['helper'] = array('autoload');Create a factory class
If you have many business classes, using a factory pattern can help you to have a common way to load all libraries.
libraries/factory.php
Code:
class factory {
function create($class_name,$your,$parameters) {
// security checks on $class_name here
...
require_once APPPATH.'/libraries/'.$class_name.'.php';
return new $class_name($your,$parameters);
}
}in controllers :
Code:
$this->load->library('factory');
$myobject =& $this->factory->create('myObject','foo','bar');Where to put classes of business logic? - El Forum - 09-25-2008

I like the idea of a factory class, very smart Dready!
