Create multiple CodeIgniter 3 applications using one installation

Introduction

CodeIgniter 3 allows you to create multiple applications using one installation by simple creating multiple application folders, each with a unique name. However, sometimes you may want your applications to share some resources for example you want your applications to share the same models, libraries and even configuration files.

For you to be able to easily do this, your can modify the CodeIgniter core/Config and core/Loader so that it can fetch resources from a location different from the respective application folder. You can create this "shared" resources folder in the root of your application and then create your normal models and libraries the same way you would do in your application folders.

This package allows you to create the following shared resources:

• models
• libraries
• config (including database config)
• helpers
• language

Once you have created these resources, you will be able to load and use them exactly the same way you would with your files in application folders. N:B. Your files in the shared resources can be overridden or extended by files in your application folders, same way you override system files in your application folders. You can also override or extend system files in the shared folder by using the MY_filename.php method.

Example - Creating 2 Applications

1 root application served by index.php and an admin application served by admin.php

• The root application will be inside the site folder and served by index.php
• The admin application will be inside the admin folder and served by admin.php

1. Download an install CodeIgniter.
2. Rename application folder to site
3. Create a copy of the site folder and name it admin
4. Download / clone this repository into the directory you installed CodeIgniter
5. Copy contents of application folder into both the site and admin folders.
6. Delete CodeIgniter default index.php file
7. Copy index.sample.php to index.php
8. Open index.php and change $application_folder = 'application'; to $application_folder = 'site'; somewhere around line 116
9. Copy index.sample.php to admin.php
10. Open index.php and change $application_folder = 'application'; to $application_folder = 'admin'; somewhere around line 116

Your directory structure should look like this:

--root
   |
   |--site/
   |--admin/
   |--shared/
   |--system/
   |--index.php
   |--admin.php
