本文實例講述了CodeIgniter集成smarty的方法。分享給大家供大家參考,具體步驟如下:
1.下載smarty
解壓到ci的libraries目錄 如:
ci/application/libraries/Smarty-2.6.20
2.編寫Mysmarty.php 自己的類庫文件
代碼如下:
<?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']) ? $config['smarty_template_dir'] : BASEPATH . 'application/views/');
$this->compile_dir = (!empty($config['smarty_compile_dir']) ? $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
?>
3.在autoload.php讓ci自動加載smarty
$autoload['libraries'] = array('database', 'mysmarty');
或者 使用模板時再自己加載smarty
$this->load->library("mysmarty");
4.smarty變量賦值 display模板
$this->mysmarty->assign('test', 'Hello World.');
$this->mysmarty->view('smarty');
注:images css 等外部資源文件 放在ci系統(tǒng)文件夾外 網(wǎng)站根目錄下
最好用:
$this->load->helper('url');
base_url()來訪問:
base_url()."images/xxx.jpg"
不要放到system里
希望本文所述對大家基于CodeIgniter框架的PHP程序設(shè)計有所幫助。
