codeigniter3整合smarty

切换到ci路径下

在application/libraries创建smarty文件夹，并将解压好的Smarty库中的libs文件夹复制到Smarty文件夹中

在application/config下创建smarty.php， 代码如下:

<?PHP
if (!defined('BASEPATH')) {
    exit('No direct script access allowed');
}
$config['cache_lifetime'] = 60;
$config['caching'] = false;
$config['template_dir'] = APPPATH . 'views/templates';
$config['compile_dir'] = APPPATH . 'views/templates_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'] = '}';

在application/libraries下创建一个Ci_Smarty.php，代码如下

<?php
if (!defined('BASEPATH')) {
    exit('No direct script access allowed');
}
require_once APPPATH.'libraries/smarty/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');
    }
}

打开application/config/autoload.php 修改

$autoload['libraries'] = array('');
改为
$autoload['libraries'] = array('Ci_Smarty');

在application/core下新建一个MY_Controller.php ，代码如下：

<?php
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);
    }
}

在views下创建templates目录

在templates下新建一个测试模板test.tpl

hello.world

在controllers下新建一个测试文件Pages.php继承MY_controller

<?php
class Pages extends MY_controller {
    public function index()
    {
        $this->display('test.tpl');
    }
}

至此完成
