Integrate Smarty to CI

[eluser]Unknown[/eluser]
This can be useful to all who wants to use smarty templates in your ci applications.

Code:

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

require APPPATH .'libraries/Smarty-2.6.20/libs/Smarty.class'.EXT;

/**
* @file system/application/libraries/Mysmarty.php
*/
class CI_Smarty extends Smarty
{
    function CI_Smarty()
    {
        $this->Smarty();

        $this->ci =& get_instance();  
        $this->ci->config->load('smarty');
        $config =& get_config();
        
        // absolute path prevents "template not found" errors
        $this->template_dir = (!empty($config['smarty']['template_dir']) ? $config['smarty']['template_dir']  : APPPATH . 'templates/');
        $this->compile_dir  = (!empty($config['smarty']['compile_dir']) ? $config['smarty']['compile_dir'] : BASEPATH . 'cache/templates_c/'); //use CI's cache folder        
        $this->cache_dir  = (!empty($config['smarty']['cache_dir']) ? $config['smarty']['cache_dir'] : BASEPATH . 'cache/pages/'); //use CI's cache folder        
        $this->config_dir  = (!empty($config['smarty']['config_dir']) ? $config['smarty']['config_dir'] : APPPATH . 'config/'); //use CI's cache folder        
        $this->plugins_dir[] = APPPATH. 'plugins'; //My Plugins

        $this->debugging = $config['smarty']['debugging'];
        
        //URL helper required
        parent::assign('url', $config['base_url']); // so we can get the full path to CI easily
        parent::assign_by_ref('this', $this->ci); //CI instance          
    }
    
    function view($resource_name, $cache_id = null)   {
        if (strpos($resource_name, '.') === false) $resource_name .= '.tpl';
        return parent::display($resource_name, $cache_id);
    }
    
} // END class smarty_library

Smarty config

Code:

//Smarty
$config['smarty']['compile_check'] = true;
$config['smarty']['caching']       = false;
$config['smarty']['debugging']     = false;

//$config['smarty']['template_dir'], $config['smarty']['compile_dir']

Examples

Code:

<?php

class Example extends Controller {

    
  function Example ()
  {  
      parent::Controller();    
        
      $this->load->library('smarty');

      $this->smarty->assign('owner', 'Me'); //or any smarty method you can use

      require_once $this->smarty->_get_plugin_filepath('modifier', 'date_left');        
      $date_left = smarty_modifier_date_left('2009-04-03 13:24:00');
  }
}
