Where to put classes of business logic?

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');
