[FuelPHP 1.7] Extend the Autoloader class

This is Kusakabe from the WEB team.

I was wondering how to extend the Autoloader class in FuelPHP 1.7, so I'm writing this down!

 

What I want to do

Extend the \Fuel\Core\Autoloader class and define it as an Autoloader class

 

How to extend FuelPHP's core classes

http://fuelphp.jp/docs/1.7/general/extending_core.html (FuelPHP 1.7)

As written here.

It's easier if you want to extend the Response class instead of the Autoloader.

You can save it as app/classes/response.php and write the correspondence between class name and file path in add_classes of app/bootstrap.php.

However, when I try to extend Autoloader using the same steps, it doesn't work.
Why? Because Autoloader is an exception!

 

Where I was worried

This is what is written at the bottom of the document

Autoloader

The Autoloader class is a special case, you can only extend it once as [ Autoloader] and have it used. After extending it you have to require it manually in the [ app/bootstrap.php] file after the original [ FuelCoreAutoloader] , don 't forget to remove the line that aliases the core class to global.

In other words, this is what it means.

 

1. Manually require the Autoloader class file that extends FuelCoreAutoloader in app/bootstrap.php
2. remove the line that aliases the core class to global (???)

 

I understand the first one! Just do it like this.

Create app/classes/autoloader.php and

At the beginning of app/bootatrap.php

Describe.

 

I didn't understand the second meaning! I didn't understand, so I ignored it and opened the page.

Cannot redeclare class Autoloader

I've been having trouble with this for a while, but I've solved it.

From the conclusion, around line 50 of public/index.php

It's ok if you comment this out.

 

What this line means is

"Create an alias from Autoloader in the global namespace to Autoloader in the FuelCore namespace"

is. See http://php.net/manual/function.class-alias.php for class_alias()

Because of this alias,

In this case, Autoloader was defined twice and inherited itself.

 

 

In summary,

When extending the core class Autoloader

1. Create app/classes/autoloader.php

   1	class Autoloader extends FuelCoreAutoloader { }

2. At the beginning of app/bootstrap.php

   1	require APPPATH.'classes'.DIRECTORY_SEPARATOR.'autoloader.php';

   describe

3. public/index.php (around line 50)

   1	class_alias('Fuel\Core\Autoloader', 'Autoloader');

   comment out

It is OK as long as you keep these three points in check. Looks like things are going well later.
