本文实例讲述了Symfony实现行为和模板中取得request参数的方法。分享给大家供大家参考,具体如下:

一.模板中取得参数

<?php echo $sf_request->getParameter('name','namespace');?>
<?php echo $sf_request->getParameter('name');?>

二.行为中取得参数

$request->getParameter('name');
//模板中取得参数
<?php echo $sf_params->get('name')?>
//带默认值的参数
<?php echo $sf_params->get('name','default')?>
//在模板中判断一个参数是否存在
<?php if($sf_params->has('name')): ?>

Hello,<?php echo $sf_params->get('name')?>!

<?php else: ?>

Hello,JohnDoe!

<?php endif; ?> //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

希望本文所述对大家基于Symfony框架的PHP程序设计有所帮助。
