本文实例讲述了CodeIgniter集成smarty的方法。分享给大家供大家参考,具体步骤如下:
1.下载smarty
解压到ci的libraries目录 如:
ci/application/libraries/Smarty-2.6.20
2.编写Mysmarty.php 自己的类库文件
代码如下:

<?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让ci自动加载smarty
1
|
$autoload [ 'libraries' ] = array ( 'database' , 'mysmarty' );
|
或者 使用模板时再自己加载smarty
1
|
$this ->load->library( "mysmarty" );
|
4.smarty变量赋值 display模板
1
2
|
$this ->mysmarty->assign( 'test' , 'Hello World.' );
$this ->mysmarty->view( 'smarty' );
|
注:images css 等外部资源文件 放在ci系统文件夹外 网站根目录下
最好用:
1
|
$this ->load->helper( 'url' );
|
base_url()来访问:
1
|
base_url(). "images/xxx.jpg"
|
不要放到system里
希望本文所述对大家基于CodeIgniter框架的PHP程序设计有所帮助。
