第一步：安裝CodeIgniter
https://ellislab.com/codeigniter/user-guide/installation/downloads.html
解壓後，複製文件夾下面的application、system、index.php至項目根目錄中
第二步：安裝Smarty
解壓之後再將下載之後的smarty模板中
放到system文件目錄
第三步：創建smarty.php
內容如下：
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
/**
* Smarty Class
*
* @package CodeIgniter
* @subpackage Libraries
* @category Smarty
* @author Kepler Gelotte
* @link http://www.coolphptools.com/codeigniter-smarty
*/
/*
echo APPPATH."\n";
echo BASEPATH.'libs/Smarty.class.php';die;*/
require_once( BASEPATH.'libs/Smarty.class.php' );
class CI_Smarty extends Smarty {
function CI_Smarty()
{
parent::Smarty();
$this->compile_dir = APPPATH . "views/templates_c";
$this->template_dir = APPPATH . "views/templates";
$this->assign( 'APPPATH', APPPATH );
$this->assign( 'BASEPATH', BASEPATH );
log_message('debug', "Smarty Class Initialized");
}
function __construct()
{
parent::__construct();
$this->compile_dir = APPPATH . "views/templates_c";
$this->template_dir = APPPATH . "views/templates";
$this->assign( 'APPPATH', APPPATH );
$this->assign( 'BASEPATH', BASEPATH );
// Assign CodeIgniter object by reference to CI
if ( method_exists( $this, 'assignByRef') )
{
$ci =& get_instance();
$this->assignByRef("ci", $ci);
}
log_message('debug', "Smarty Class Initialized");
}
/**
* Parse a template using the Smarty engine
*
* This is a convenience method that combines assign() and
* display() into one step.
*
* Values to assign are passed in an associative array of
* name => value pairs.
*
* If the output is to be returned as a string to the caller
* instead of being output, pass true as the third parameter.
*
* @access public
* @param string
* @param array
* @param bool
* @return string
*/
function view($template, $data = array(), $return = FALSE)
{
foreach ($data as $key => $val)
{
$this->assign($key, $val);
}
if ($return == FALSE)
{
$CI =& get_instance();
if (method_exists( $CI->output, 'set_output' ))
{
$CI->output->set_output( $this->fetch($template) );
}
else
{
$CI->output->final_output = $this->fetch($template);
}
return;
}
else
{
return $this->fetch($template);
}
}
}
// END Smarty Class
?>
第四步：在application下config目錄下的 autoload.php文件修改如下：
$autoload['libraries'] = array('smarty');
第五步：在application/views 下面創建templates_c 和 templates 二個文件夾
