前端之家收集整理的这篇文章主要介绍了
CodeIgniter使用phpcms模板引擎，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
@H_502_0@CodeIgniter很适合小站点应用开发，但是它自带的view功能可能会给不懂PHP的前端人员带来麻烦。 相比之下PHPcms的view模板解析就强大多了，所以这里就把PHPCMS的模板解析功能剥离出来，加到PHPCMS上。
首先在CodeIgniter libraries中 增加 template_cache.PHP
<div class="codetitle"><a style="CURSOR: pointer" data="84722" class="copybut" id="copybut84722" onclick="doCopy('code84722')"> 代码如下:
<div class="codebody" id="code84722">
<?
PHP if (!defined('BASEPATH')) exit('No direct script access allowed');
/
模板解析缓存
/
final class template_cache { public $cache_path;
public function __construct()
{
//$CI =& get_instance();
$this->cache_path = APPPATH.'views';
} / 编译模板
@param $module 模块名称
@param $template 模板
文件名
@param $istag 是否为标签模板
@return unknown
*/ public function template_compile($module,$template,$style = 'default') { $tplfile= APPPATH.'views'.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR.$template.'.
PHP'; if (! file_exists ( $tplfile )) {
show_error($tplfile,500,'Template does not exist(1)');
} $content = @file_get
contents ( $tplfile );
@H502_0@ $filepath = $this->cache_path.DIRECTORY_SEPARATOR.'caches_template'.DIRECTORY_SEPARATOR.$style.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR;
