Detailed explanation of the method of integrating smarty with CodeIgniter, codeignitersmarty

The example in this article describes the method of integrating smarty with CodeIgniter. Share it with everyone for your reference. The specific steps are as follows:

1. Download smarty

Extract to the libraries directory of ci, such as:

ci/application/libraries/Smarty-2.6.20

2. Write your own class library file Mysmarty.php

The code is as follows:

<&#63;php if (!defined('BASEPATH')) exit('No direct script access allowed');
require "Smarty-2.6.20/libs/Smarty.class.php";
/**
* @file system/application/libraries/Mysmarty.php
*/
class Mysmarty extends Smarty
{
  function Mysmarty()
  {
    $this->Smarty();
    $config =& get_config();
    // absolute path prevents "template not found" errors
    $this->template_dir = (!empty($config['smarty_template_dir']) &#63; $config['smarty_template_dir'] : BASEPATH . 'application/views/');
    $this->compile_dir = (!empty($config['smarty_compile_dir']) &#63; $config['smarty_compile_dir'] : BASEPATH . 'cache/'); 
    //use CI's cache folder
    if (function_exists('site_url')) {
      // URL helper required
      $this->assign("site_url", site_url()); // so we can get the full path to CI easily
    }
  }
  /**
  * @param $resource_name string
  * @param $params array holds params that will be passed to the template
  * @desc loads the template
  */
  function view($resource_name, $params = array())  {
    if (strpos($resource_name, '.') === false) {
      $resource_name .= '.html';
    }
    if (is_array($params) && count($params)) {
      foreach ($params as $key => $value) {
        $this->assign($key, $value);
      }
    }
    // check if the template file exists.
    if (!is_file($this->template_dir . $resource_name)) {
      show_error("template: [$resource_name] cannot be found.");
    }
    return parent::display($resource_name);
  }
} // END class smarty_library
&#63;>

Copy after login

3. Let ci automatically load smarty in autoload.php

$autoload['libraries'] = array('database', 'mysmarty');

Copy after login

Or load smarty yourself when using a template

$this->load->library("mysmarty");

Copy after login

4.smarty variable assignment display template

$this->mysmarty->assign('test', 'Hello World.');
$this->mysmarty->view('smarty');

Copy after login

Note: external resource files such as images css are placed outside the ci system folder in the root directory of the website

Best to use:

$this->load->helper('url');

Copy after login

base_url() to access:

base_url()."images/xxx.jpg"

Copy after login

Don’t put it in the system
