CodeIgniter Autoload Hook by Shane Pearson – Modified

Shane Pearson used to have this up on BitBucket, but he’s since deleted it. If you were to get a copy of it from his blog post and try to run it in CodeIgniter 2.1.3 or newer, you’ll find that it stopped working. This is because Shane utilized a constant that has been marked as deprecated for quite some time now that has finally been removed. Anyway, I use this lib, so I’m going to post my updates to it for others. I won’t explain it, as Shane does a very good job of that himself. Just go to his blog post to see it.

// change the enable_hooks setting in ./application/config/config.php to read as so:
$config['enable_hooks'] = true;

// This goes into ./application/config/hooks.php
$hook['pre_system'] = array(
	'class' => 'MY_Autoloader',
	'function' => 'register',
	'filename' => 'MY_Autoloader.php',
	'filepath' => 'hooks',
	'params' => array(APPPATH.'core/')
	// moved to reflect CodeIgniters core file path - mladoux
	//'params' => array(APPPATH.'base/')
);
