Symfony实现行为和模板中取得request参数的方法_php实例

<&#63;php echo $sf_request->getParameter('name','namespace');&#63;>
<&#63;php echo $sf_request->getParameter('name');&#63;>

$request->getParameter('name');
//模板中取得参数
<&#63;php echo $sf_params->get('name')&#63;>
//带默认值的参数
<&#63;php echo $sf_params->get('name','default')&#63;>
//在模板中判断一个参数是否存在
<&#63;php if($sf_params->has('name')): &#63;>
<p>Hello,<&#63;php echo $sf_params->get('name')&#63;>!</p>
<&#63;php else: &#63;>
<p>Hello,JohnDoe!</p>
<&#63;php endif; &#63;>
//包含所有参数的数组
$request->getParameterHolder()->getAll()
//完整的URI路径
//'http://localhost/myapp_dev.php/mymodule/myaction'
getUri()
//'/mymodule/myaction'
getPathInfo()
//在action中
$hasFoo =$this->getRequest()->hasParameter('foo');
$hasFoo = $this->hasRequestParameter('foo');//Shorter version
$foo  =$this->getRequest()->getParameter('foo');
$foo  =$this->getRequestParameter('foo'); //Shorterversion
