Twig library for CodeIgniter 2.x and 3.x using Composer

Installation

First, create twig cache directory under application/cache; and give it write permission

$ mkdir -p application/cache/twig
$ chmod o+w application/cache/twig

Add the Twig config file to application/config/twig.php

Use the composer to install the latest Twig.

Set the composer vendor path in the Twig libraries file:

require_once (COMPOSER_VENDORPATH . 'autoload.php');

Usage

Put in your controller:

$this->load->library('twig');
$data['title'] = "Testing Twig!!";
$this->twig->display('view.html', $data);

CodeIgniter helper functions

If you want to use CodeIgniter helper functions in Twig templates do this in your controller.

$this->load->library('twig'); // load the Twig library
$this->load->helper('url'); // load the CodeIgniter URL helper
// map the base_url() function as a Twig function 
$this->twig->add_function('base_url'); 

Then in your Twig view call the base_url() function like this

{{ base_url() }}
