CodeIgniter Modifications

We are following the standard project folder, you might see few available directories: docs, license, public, src and tests.

Few modifications, enhancement and rewriting have been done to suit the need of the application. These are few to none changes but we have to mention them due to license agreement and so that you know what to do in case of a new CodeIgniter release.

• index.php
• CodeIgniter.php
• Common.php

index.php

On this file, we have first added the path to src folder which starts from line #92 to line #102.

/*
 *---------------------------------------------------------------
 * Path to skeleton folder.
 *---------------------------------------------------------------
 *
 * This folder contains all files that override or extend
 * CodeIgniter core classes and files.
 *
 */
	$skeleton_src = '_PATH_TO_SRC_DIR';
	$skeleton_path = "{$skeleton_src}/skeleton";

At line #251 and line #254 we have defined two useful constants:

// Define the path to skeleton folder.
define('KBPATH', $skeleton_path.DIRECTORY_SEPARATOR);

// Define a constant representing DIRECTORY_SEPARATOR.
define('DS', DIRECTORY_SEPARATOR);

CodeIgniter.php

• At line #75 we included our custom constants.php file that holds some useful constants including the Skeleton version KB_VERSION.

// Some useful constants are added.
require_once(KBPATH.'config/constants.php');

• Lines from #405 up to #411 we replace by our custom check. In the modified file you will find them from #408 up to #425.

// 405-411 | Original file:
if (empty($class) OR ! file_exists(APPPATH.'controllers/'.$RTR->directory.$class.'.php'))
{
	$e404 = TRUE;
}
else
{
	require_once(APPPATH.'controllers/'.$RTR->directory.$class.'.php');

// 408-425 | Modified file:
if (empty($class))
{
	$e404 = TRUE;
}
else
{
	if (file_exists(APPPATH.'controllers/'.$RTR->directory.$class.'.php'))
	{
		require_once(APPPATH.'controllers/'.$RTR->directory.$class.'.php');
	}
	elseif (file_exists(KBPATH.'controllers/'.$RTR->directory.$class.'.php'))
	{
		require_once(KBPATH.'controllers/'.$RTR->directory.$class.'.php');
	}
	else
	{
		$e404 = TRUE;
	}

Common.php

The load_class function has been altered a little bit. In fact we have added our custom path to class loading and we are loading our custom classes right after core classes are loaded in order to enhance or override behavior. At line #155:

// Before
foreach (array(APPPATH, BASEPATH) as $path)

// After
foreach (array(APPPATH, KBPATH, BASEPATH) as $path)

From line ** #170** to line #182, here is where we load our custom classes to enhance or override behavior:

/**
 * Load any existing class with our custom subclass prefix 'KB_',
 * we do this to allow the user to extend core classes with the
 * prefix set in application/config/config.php file.
 */
if (file_exists(KBPATH.$directory.'/KB_'.$class.'.php'))
{
	$name = 'KB_'.$class;
	if (class_exists($name, FALSE) === FALSE)
	{
		require_once(KBPATH.$directory.'/KB_'.$class.'.php');
	}
}
