README

You can integrate the Mw Http framework with CI by embedding an Mw app inside of the CI framework.

The idea for this integration came from a legacy site I've managed before where we couldn't remove the old CI framework, but we needed to add new features that the Mw Http Framework could solve. So, this allows a nice bridge from an older system to a new one.

Installation

Install with composer at krak/mw-codeigniter

Usage

To have an app that you want to embed inside of the CI framework, you'll need to do a few things.

1. Create a controller to handle the Mw Routes named like application/controllers/mw.php
2. Create your mw app inside of the controller method.

<?php

use Krak\Mw\Http;

class Mw extends CI_Controller
{
    public function index() {
        $app = new Http\App();
        $app->with(Http\Package\std());
        $app->with(Http\Package\codeIgniter($this));

        $app->get('/a', function() {
            return '/a';
        });
        $app->get('/b', function() {
            return '/b';
        });
        $app->get('/exception', function() {
            throw new \InvalidArgumentException('Whoa!!!!');
        });

        $app->serve();
    }
}

1. Register the default route to point to your mw/index action. All undefined routes will lead to it now.

<?php

$route['404_override'] = 'mw';

Make sure to add the CodeIgniter package last or at least later on in the packages.

API

These are all relative to the Krak\Mw\Http\Package namespace.

codeIgniter($ci, array $config = [])

returns a configured instance of CodeIgniter\CodeIgniterPackage. $ci must be an instance of the Codeigniter controller. $config is an array that allows the following configuration options:

show_stack_trace

Forwarded to ciExceptionHandler

CodeIgniter\ciExceptionHandler($show_stack_trace = true)

An exception handler that will use the CI show_error global func to display the exception. $show_stack_trace determines whether or not to display the stack trace of the exception along with the exception message.

CodeIgniter\ciNotFoundHandler()

Simply uses the show_404 method from the CI framework to display a page not found.

CodeIgniter\ciViewMarshalResponse($ci)

Allows actions to return two-tuples of [string, array] which represent the view path and the data to load into the view. This internally uses the $this->load->view method in the CI framework.

CodeIgniter\CodeIgniterServiceProvider

The service provider defines the following services:

codeigniter.server

This is a KrakMwHttpServer which serves from inside of the CI framework.

server

Replaces the server parameter with the codeigniter.server instance.

Required Parameters

codeigniter.ci

An isntance of CI. This value is automatically filled if you are using the CodeIgniterPackage interface; however, it will need to be set if you are using the service provider on its own.
