Question

I want to use a central CI setup for multiple sites. The way I handle this is I created a package called MPACK and added it to autoload in the config file of each site.

Folder Structure:

/main

/system (CI 2 System folder)

/MPACK

/site1

/application

site2

/application

Inside this MPACK I have share libraries, models, helpers, etc.

However, I would like to have an extended MY_Form_Validation that would be common to ALL sites. Adding the class file to /MPACK/libraries fails. Adding it to /site1/application works fine, as expected.

Is there any way to do this extending inside MPACK?

Thank you for your time.

Answer 1

Please try this:

// Placed your MY_Form_validation.php under MPACK/libraries
$this->load->add_package_path('/path/to/MPACK');
$this->load->library('form_validation');

You can get more information from CodeIgniter User Guide – Loader Class. 🙂

You can also autoload your package in /application/config/autoload.php : $autoload['packages'] = array('/path/to/MPACK');

EDIT: turn out that the above solution doesn’t work, because Loader always look for APPPATH & BASEPATH first, and I not sure modifying this core class won’t break something. Here is another solution in theory:

You should have your MPACK form validation lib, and sites’ form validation lib should be symlinks to the MPACK one:

/site1/application/MY_Form_validation.php -> /MPACK/libraries/MY_Form_validation.php

If you just use everything from MPACK, nothing specifically for /site1 or /site2, just make a folder link:

/site1/application/libraries/ -> /MPACK/application/libraries/

Hope this help =)
