Symfony模板的快捷变量用法实例,symfony模板实例

本文实例讲述了Symfony模板的快捷变量用法。分享给大家供大家参考,具体如下:

在模板里,有一些symfony变量可以直接使用。通过这些快捷变量可以从symfony的对象里取得一些最常用的模板信息:

$sf_context:完整的环境对象(sfContext 类的实例)
$sf_request:请求对象(sfRequest 类的实例)
$sf_params:请求的参数
$sf_user:当前的用户session对象(sfUser 类的实例)

三种常见的使用方法:

//1. 长版本
<&#63;php echo $sf_request->getParameter('total') &#63;>
//2. 段版本
<&#63;php echo $sf_params->get('total') &#63;>
//3. 相当于在行为里执行下面的代码
echo $request->getParameter('total')

Copy after login

希望本文所述对大家基于Symfony框架的PHP程序设计有所帮助。
