Merging a CI app with EE2

[eluser]Nathan Pitman (Nine Four)[/eluser]
Hi all, I'm trying to merge a CI app which we have developed with a EE2 install such that the CI app can run off the version of CI which ships with EE2. Thus far I have EE2 installed and running with no problems and I have moved my index.php for my CI app into a sub folder. However when I try to access my CI app it's returning a similar error on all controllers:

Code:

Fatal error: Class 'Controller' not found in /home/ihasco/subdomains/dev/system/app/controllers/training.php on line 10

I'm guessing there's something I've missed in the CI index.php file perhaps or is it simply not possible to do what I'm trying... I had assumed that EE2 was just using a stable build of CI as it's base so would be able to point at that from my application...

Any help greatly appreciated!

Sounds like you're trying to extend Controller instead of CI_Controller, which is a v2 change

[eluser]Nathan Pitman (Nine Four)[/eluser]
ah! You may be my savior! Yes... this app is running on CI 1.7.2!

Of course I'm now getting another error:

Code:

Fatal error: Call to undefined method CI_Controller::Controller() in /home/ihasco/subdomains/dev/system/app/controllers/training.php on line 15

So I'm guessing something here needs changing...

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

/*
    +-----------------------------------------------------------------------+
    | CLASS: Training                                                           |
    +-----------------------------------------------------------------------+
    | Handles all aspects of online training                                |
    +-----------------------------------------------------------------------+
*/

class Training extends CI_Controller {

    function Training()
    {
        parent::Controller();
        $this->load->model('client');
        $this->load->model('messaging');
        $this->load->model('user');
        $this->load->model('result');
        $this->load->model('payperview');
        $this->load->helper('general_helper');
        $this->load->helper('url');
    }

    public function index()
    {

        // Defaults for preview
        $data = array();
        $data['debug'] = false;
        $data['view_only'] = false;
        $data['logged_in'] = false;
        ...

:?

replace

<code>
parent::Controller();
</code>

with

<code>
parent::__construct();
</code>

[eluser]toopay[/eluser]
also...

Code:

// replace
function Training()
// into
function __construct()

It's so almost there, I'm stuck with a one final challenge though, the .htaccess rewrites... I decided to go the route of switching things round and having the CI app as the default (index.php) and EE2 called via expressionengine.php. So both these files reside in the /public_html folder along with my .htaccess. What I wish to do is route all traffic for a specific set or controller names to the CI app and everything else to EE2, so I was thinking something along the lines of:

Code:

<IfModule mod_rewrite.c>
RewriteEngine On

RewriteCond %{HTTP_HOST} !^my\.domain\.com [NC]
RewriteCond $1 !webservices/
RewriteRule ^(.*)$ http://my.domain.com/$1 [R=301,L]

RewriteBase /
RewriteCond $1 !^(admin|cron|fst_reporting|playcatch|ppv|purchase|reporting|training|xml) [NC]
RewriteRule ^(.*)$ expressionengine.php/$1 [L]

RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
# Submitted by: ElliotHaughin

ErrorDocument 404 /index.php
</IfModule>

But I'm not having any luck, this just throws a server error so I must be completely out of whack somewhere... :/

Its related with environment issues i believe. Working on this htaccess section, with some regex variation.

Code:

RewriteBase /
# If, you put CI package on subdirectory, specify it
# RewriteBase /ci_dir/

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.*)$ index.php/$1 [L]
# Play around/replace above line with each one line, below.
# RewriteRule ^(.*)$ index.php?/$1 [L]
# RewriteRule ^.*$ index.php/$1 [L]
# If, you put CI package on subdirectory, specify it
# RewriteRule ^(.*)$ ci_dir/index.php/$1 [L]
# RewriteRule ^(.*)$ /ci_dir/index.php/$1 [L]
# RewriteRule ^(.*)$ ci_dir/index.php?/$1 [L]
# RewriteRule ^(.*)$ /ci_dir/index.php?/$1 [L]
# RewriteRule ^.*$ ci_dir/index.php/$1 [L]
# RewriteRule ^.*$ /ci_dir/index.php/$1 [L]

Ok, I managed to get it working! Here's what I did:

1) Placed the CI app front end loader (index.php) in a sub folder (/app).
2) reverted back to having the EE front loader as index.php in the site root.
3) Modified my .htaccess file to read as follows:

Code:

<IfModule mod_rewrite.c>
RewriteEngine On

RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.mydomain\.com [NC]
RewriteRule ^(.*)$ http://www.mydomain.com/$1 [R=301,L]

# Rewrite requests for anything that's NOT a CI controller or physical file/folder to ExpressionEngine
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !(admin|cron|fst_reporting|playcatch|ppv|purchase|reporting|training|xml) [NC]
RewriteRule ^(.*)$ /index.php/$1 [L]

# Route everything else to CodeIgniter
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /app/index.php/$1 [L]

# Rejoice!

</IfModule>

<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
# Submitted by: ElliotHaughin

ErrorDocument 404 /index.php
</IfModule>

Now I can specify controller names that need to be routed to CI and everything else get's routed to EE2!

Hoorah!
