Using the universal template engine smarty in the CI framework

CI version: 2.1.4 // The latest version at this time
Smarty version: Smarty-2.6.26 // Because I used this version before, in order to take care of my own usage habits, I did not use the latest Smaty version here. , everyone understands the expansion principle and can choose the Smatry version they want to use.


1. Download the Smarty source code package from the corresponding site; // I am using Smarty-2.6.26 here
2. Copy the libs folder in the source code package to the CI project In the libraries folder under the directory, rename it to Smarty-2.6.26; //
3. Create a new file Cismarty.php in the libraries folder of the project directory. The contents are as follows:

<?php 
if(!defined(&#39;BASEPATH&#39;)) EXIT(&#39;No direct script asscess allowed&#39;); 
require_once( APPPATH . &#39;libraries/Smarty-2.6.26/libs/Smarty.class.php&#39; ); 
class Cismarty extends Smarty { 
    protected $ci; 
    public function  __construct(){ 
        $this->ci = & get_instance(); 
        $this->ci->load->config(&#39;smarty&#39;);//加载smarty的配置文件 
        //获取相关的配置项 
        $this->template_dir   = $this->ci->config->item(&#39;template_dir&#39;); 
        $this->complie_dir    = $this->ci->config->item(&#39;compile_dir&#39;); 
        $this->cache_dir      = $this->ci->config->item(&#39;cache_dir&#39;); 
        $this->config_dir     = $this->ci->config->item(&#39;config_dir&#39;); 
        $this->template_ext   = $this->ci->config->item(&#39;template_ext&#39;); 
        $this->caching        = $this->ci->config->item(&#39;caching&#39;); 
        $this->cache_lifetime = $this->ci->config->item(&#39;lefttime&#39;); 
    } 
}

4. Create a new file smarty.php in the config folder of the project directory. The contents are as follows:

<?php  if ( ! defined(&#39;BASEPATH&#39;)) exit(&#39;No direct script access allowed&#39;); 
$config[&#39;theme&#39;]        = &#39;default&#39;; 
$config[&#39;template_dir&#39;] = APPPATH . &#39;views&#39;; 
$config[&#39;compile_dir&#39;]  = FCPATH . &#39;templates_c&#39;; 
$config[&#39;cache_dir&#39;]    = FCPATH . &#39;cache&#39;; 
$config[&#39;config_dir&#39;]   = FCPATH . &#39;configs&#39;; 
$config[&#39;template_ext&#39;] = &#39;.html&#39;; 
$config[&#39;caching&#39;]      = false; 
$config[&#39;lefttime&#39;]     = 60;

5. Create a new folder templates_c in the directory where the entry file is located. cache, configs;
6. Find the autoload.php file in the config directory under the project directory
Modify this item

$autoload['libraries'] = array('Cismarty');/ /The purpose is: let the system load automatically when it is running, without having to manually load it in the controller


7. Create a new file MY_Controller.php in the core folder of the project directory with the following content: // Extended core control class

<?php if (!defined(&#39;BASEPATH&#39;)) exit(&#39;No direct access allowed.&#39;); 
class MY_Controller extends CI_Controller { // 原文这里写错 
    public function __construct() { 
        parent::__construct(); 
    } 
    public function assign($key,$val) { 
        $this->cismarty->assign($key,$val); 
    } 
    public function display($html) { 
        $this->cismarty->display($html); 
    } 
}

Configuration completed


------------------------ -------------------------------------------------- -------------------------------------------------- --------------------------
Usage method example:
In the controller, such as:

<?php if ( ! defined(&#39;BASEPATH&#39;)) exit(&#39;No direct script access allowed&#39;); 
class Welcome extends MY_Controller { // 原文这里写错 
    public function index() 
    { 
        //$this->load->view(&#39;welcome_message&#39;); 
        $data[&#39;title&#39;] = &#39;标题&#39;; 
        $data[&#39;num&#39;] = &#39;123456789&#39;; 
        //$this->cismarty->assign(&#39;data&#39;,$data); // 亦可 
        $this->assign(&#39;data&#39;,$data); 
        $this->assign(&#39;tmp&#39;,&#39;hello&#39;); 
        //$this->cismarty->display(&#39;test.html&#39;); // 亦可 
        $this->display(&#39;test.html&#39;); 
    } 
}

Then in the view: the view folder is located under views in the project directory:
New file test.html

<!DOCTYPE html> 
<html> 
<head> 
<meta charset="utf-8"> 
<title>{ $test.title}</title> // 原文是 <title>{$test[&#39;title&#39;]}</title>，是错误的写法，也有可能是Smarty版本的原因 
<style type="text/css"> 
</style> 
</head> 
<body> 
{$test.num|md5} // 原文这里也写错了 
<br> 
{$tmp} 
</body> 
</html>
