本文实例讲述了CodeIgniter整合Smarty的方法。分享给大家供大家参考,具体如下:
CI3.0.2发布后感觉模板类还是不怎么好用,而且不能编译。Smarty功能强大,用习惯了Smarty标签,一般难以放弃,而且,是可以编译文件执行,速度快,我们可以把它们整合使用,弥补CI的模板功能的不足。我们整合使用的是CI版本3.0.3及 Smarty版本3.1.27。下面描述整合过程。
1、下载smarty-3.1.27
2 、解压smarty-3.1.27到CI项目中的application/libraries下面,其他的文件删除。
3、 在application/libraries目录下创建Ci_smarty.php文件,代码如下:
if ( ! defined('BASEPATH')) exit('No direct script access allowed');require(APPPATH.'libraries/smarty-3.1.27/libs/Smarty.class.php');class Ci_smarty extends Smarty { protected $ci; public function __construct() { parent::__construct(); $this->ci = & get_instance(); $this->ci->load->config('smarty');//加载smarty的配置文件 $this->cache_lifetime =$this->ci->config->item('cache_lifetime'); $this->caching = $this->ci->config->item('caching'); $this->config_dir = $this->ci->config->item('config_dir'); $this->template_dir = $this->ci->config->item('template_dir'); $this->compile_dir = $this->ci->config->item('compile_dir'); $this->cache_dir = $this->ci->config->item('cache_dir'); $this->use_sub_dirs = $this->ci->config->item('use_sub_dirs'); $this->left_delimiter = $this->ci->config->item('left_delimiter'); $this->right_delimiter = $this->ci->config->item('right_delimiter'); }}
4、在application/config目录下创建配置文件smarty.php,代码如下:
if ( ! defined('BASEPATH')) exit('No direct script access allowed');$config['cache_lifetime'] = 60;$config['caching'] = false;$config['template_dir'] = APPPATH .'views';$config['compile_dir'] = APPPATH .'views/template_c';$config['cache_dir'] = APPPATH . 'views/cache';$config['config_dir'] = APPPATH . 'views/config';$config['use_sub_dirs'] = false; //子目录变量(是否在缓存文件夹中生成子目录)$config['left_delimiter'] = '{';$config['right_delimiter'] = '}';
5、在application/core创建MY_controller.php,代码如下:
class MY_controller extends CI_Controller { public function __construct() { parent::__construct(); } public function assign($key,$val) { $this->ci_smarty->assign($key,$val); } public function display($html) { $this->ci_smarty->display($html); }}
至此,配置整合工作over了,下面我们要验证是否配置成功。
7、修改application/controllers的Welcome.php,代码如下:
defined('BASEPATH') OR exit('No direct script access allowed');class Welcome extends MY_controller { public function index() { $test='ci 3.0.3 + smarty 3.1.27 配置成功'; $this->assign('test',$test); $this->display('test.html'); }}
