Modular Extensions - HMVC version 5.4

[eluser]Unknown[/eluser]
I recently had to do this so I thought I would post it in the hopes that someone can find it useful.

My goal was to make all models within any modules autoload when instantiated (but not before) by tying into PHP's spl_autoload functionality. HMVC already uses this to autoload MX classes as well as core and library classes, so I just added to that.

In the APP_ROOT/third_party/MX/Modules.php file you simply need to add the following to the autoload method which already exists there (the function starts on line 111).

Code:

/* autoload module classes */
  $module_path = str_replace('/'.SYSDIR, '' ,BASEPATH)."application/modules/";
  if($dir = opendir($module_path))
  {
   while(false !== ($current_dir = readdir($dir)))
   {
    if(is_file($location = APPPATH.'modules/' . $current_dir . '/models/' . strtolower($class).EXT)){
     include_once $location;
     return;
    }
   }
  }

This will work assuming your (relevant) directory layout is structured something like this (if your directory structure is slightly different, you can modify the paths/etc. in the above to match your case)

Code:

/ -
  - applications
    - modules
      - module_name
        - models
          - test_model.php
          - test2_model.php
      - module2_name
        - models
          - test_model.php

The end result is that I can do something like this in my controllers without having to do any call of include_once/require_once or $this->load, etc. and the models are included automatically when I call them (rather than either all in the beginning using the autoload array or manually).

Code:

// middle of some controller
function example() {
    // non-static method
    $test = new Test_Model();
    $test->do_something();

    // static method
    $test_data = Test2_Model::get_some_data();
}

Anyways, hope that helps someone.
