本文讲述了ThinkPHP模板替换与系统常量及应用,是ThinkPHP项目开发的基础知识,有必要加以牢固掌握。具体如下:

默认的模板替换规则:

../Public : 会被替换成当前项目的公共模板目录 通常是 / 项目目录 /Tpl/default/Public/
__PUBLIC__ :会被替换成当前网站的公共目录 通常是 /Public/
__TMPL__ : 会替换成项目的模板目录 通常是 / 项目目录 /Tpl/default/
__ROOT__ : 会替换成当前网站的地址(不含域名)
__APP__ : 会替换成当前项目的 URL 地址 (不含域名)
__URL__ : 会替换成当前模块的 URL 地址(不含域名)
__ACTION__ :会替换成当前操作的 URL 地址 (不含域名)
__SELF__ : 会替换成当前的页面 URL

还可以通过在项目配置文件中配置TMPL_PARSE_STRING的值来自定义替换规则,如:

TMPL_PARSE_STRING => array(
   '__PUBLIC__' => '/Common' ,  // 更改默认的 __PUBLIC__ 替换规则
   '__UPLOAD__' => '/Public/Uploads/' ,  // 增加新的上传路径替换规则
)
Copy after login

示例:

文件路径:/Home/Tpl/default/User/index.html,代码如下:

 <p>__ROOT__代表当前网站的网址</p>
 <p>__URL__代表当前模块的URL地址/index.php/User</p>
 <p>../Public代表/aoli/Tpl/default/Public</p>
 <p>__PUBLIC__代表项目公共文件目录/Public</p>
 <p>__TMPL__代表当前项目的模板目录/aoli/Tpl/default/</p>
 <p>__APP__代表当前项目的入口文件地址/index.php</p>
 <p>__ACTION__代表当前的操作地址/index.php/User/index</p>
 <p>__SELF__代表当前URL地址/index.php/User/</p>
 <p>__UPLOAD__</p>
 <form action="__URL__/add" method="post">
  <input type="text" name="username" />
  <input type="submit" value="注册" />
 </form>
Copy after login

文件路径:/Home/Lib/Action/UserAction.class.php,代码如下:

<&#63;php
 class UserAction extends Action {
    function index(){
      $this->display();     
    }
    function add(){
      dump($_POST);   
    }
 }
&#63;>
Copy after login

访问路径:http://localhost/index.php/User/index输入内容,点击注册按钮后跳转到http://localhost/index.php/User/add并执行User模块下的add方法,输出提交的内容。
