Have the following (simplified) setup:
/modules/backend/libraries/Queue/Queue.php
/modules/backend/libraries/Queue/drivers/Queue_a.php
/modules/backend/libraries/Queue/drivers/Queue_b.php
/modules/admin/controllers/Test.php
Am attempting to use Queue driver library inside of Test controller - ie across modules.
The basic load of driver library works, but the driver library is unable to find/load its child drivers/drivername.
This works in Test.php if Queue::add is a stub (ie not doing anything)
PHP Code:
function test()
{
$this->load->library('backend/queue','queue');
$this->queue->add('test message');
}
But, when the library then tries to load an individual driver (e.g. to add an item into a queue), the load fails: (in Queue/Queue.php)
PHP Code:
function add($payload='')
{
//...ignore code that picks which driver to use - assume its queue_a
$this->queue_a->add_message($payload); //this fails, Queue_a.php cannot be found to load
}
The problem seems to be that HMVC overrides the core Loader.php file - but the code in core/libraries/Driver.php that locates individual driver child classes is not HMVC aware, and does not use the Loader class.
My first thought for solution is to extend core/libraries/Driver.php in new file MX_Driver.php:
PHP Code:
public function __get($child)
{
//establish path of child driver
$lib_name = get_class($this);
$reflector = new ReflectionClass($lib_name);
$class_path = dirname($reflector->getFileName());
$lib_path = dirname($class_path);
$module_path = dirname($lib_path);
//temp add the path for CI loader to find
$this->CI->load->add_package_path($module_path);
// Try to load the driver
return $this->load_driver($child);
// Reset things to clean up
$this->load->remove_package_path($module_path);
}
Have a feeling this has been solved before however?
