CHttpRequest problem

Hello,

I have a class Controller extendes CController.

Fore example, make an easy function:

  public function init()

  {

    $sRefUrl = CHttpRequest::getUrlReferrer(); // Is OK

    $sUrl = CHttpRequest::getUrl(); // exeption "Property \"SiteController._url\" is not defined."

    $sReqUrl = CHttpRequest::getRequestUri(); // exeption "Property \"SiteController._requestUri\" is not defined."

  }

Where I’m wrong and why I can use CHttpRequest::getUrlReferrer() but can’t use others?

Thanks a lot in advance.

  public function init()

  {

    $sRefUrl = CHttpRequest::getUrlReferrer(); 

    $sUrl = yii::app()->getRequest()->getUrl(); 

    $sReqUrl = yii::app()->getRequest()->getRequestUri(); 

  }

Above code worx fine. But still not clear, why static methods not worx. May be some guru can explain this behavior?

Because if you look at source of framework/web/CHttpRequest.php

Public function doesn’t call any internal private variable.

public function getUrlReferrer()

	{

		return isset($_SERVER['HTTP_REFERER'])?$_SERVER['HTTP_REFERER']:null;

	}

That works fine, so, when you call this function without creating the class instance it just return you http referer string.

But when you look at getUrl function:

public function getUrl()

	{

		if($this->_url!==null)

			return $this->_url;

		else

		{

			if(isset($_SERVER['REQUEST_URI']))

				$this->_url=$_SERVER['REQUEST_URI'];

			else

			{

				$this->_url=$this->getScriptUrl();

				if(($pathInfo=$this->getPathInfo())!=='')

					$this->_url.='/'.$pathInfo;

				if(($queryString=$this->getQueryString())!=='')

					$this->_url.='?'.$queryString;

			}

			return $this->_url;

		}

	}

You’ll see that there’ used private variable “private $_url;” which can’t be accessed without creating an instance of class.

When you try to use this code, then all should be fine:

$request = CWebApplication::getRequest();

var_dump($request->getUrlReferrer().$request->getUrl().$request->getRequestUri());
