CCookieCollection

Source Code framework/web/CHttpRequest.php
CCookieCollection implements a collection class to store cookies.

You normally access it via CHttpRequest::getCookies().

Since CCookieCollection extends from CMap, it can be used like an associative array as follows: 
$cookies[$name]=new CHttpCookie($name,$value); // sends a cookie
$value=$cookies[$name]->value; // reads a cookie value
unset($cookies[$name]);  // removes a cookie

Method Details

__construct() method
public void __construct(CHttpRequest $request)
$request CHttpRequest owner of this collection.
Source Code: framework/web/CHttpRequest.php#662 (show)
public function __construct(CHttpRequest $request)
{
    $this->_request=$request;
    $this->copyfrom($this->getCookies());
    $this->_initialized=true;
}

Constructor.

add() method
public void add(integer $name, mixed $cookie)
$name integer the specified position.
$cookie mixed new item
Source Code: framework/web/CHttpRequest.php#708 (show)
public function add($name,$cookie)
{
    if($cookie instanceof CHttpCookie)
    {
        $this->remove($name);
        parent::add($name,$cookie);
        if($this->_initialized)
            $this->addCookie($cookie);
    }
    else
        throw new CException(Yii::t('yii','CHttpCookieCollection can only hold CHttpCookie objects.'));
}

Inserts an item at the specified position. This overrides the parent implementation by performing additional operations for each newly added CHttpCookie object.

addCookie() method
protected void addCookie(CHttpCookie $cookie)
$cookie CHttpCookie cook to be sent
Source Code: framework/web/CHttpRequest.php#742 (show)
protected function addCookie($cookie)
{
    $value=$cookie->value;
    if($this->_request->enableCookieValidation)
        $value=Yii::app()->getSecurityManager()->hashData($value);
    if(version_compare(PHP_VERSION,'5.2.0','>='))
        setcookie($cookie->name,$value,$cookie->expire,$cookie->path,$cookie->domain,$cookie->secure,$cookie->httpOnly);
    else
        setcookie($cookie->name,$value,$cookie->expire,$cookie->path,$cookie->domain,$cookie->secure);
}

Sends a cookie.

getCookies() method
protected array getCookies()
{return} array list of validated cookies
Source Code: framework/web/CHttpRequest.php#680 (show)
protected function getCookies()
{
    $cookies=array();
    if($this->_request->enableCookieValidation)
    {
        $sm=Yii::app()->getSecurityManager();
        foreach($_COOKIE as $name=>$value)
        {
            if(($value=$sm->validateData($value))!==false)
                $cookies[$name]=new CHttpCookie($name,$value);
        }
    }
    else
    {
        foreach($_COOKIE as $name=>$value)
            $cookies[$name]=new CHttpCookie($name,$value);
    }
    return $cookies;
}

getRequest() method
public CHttpRequest getRequest()
{return} CHttpRequest the request instance
Source Code: framework/web/CHttpRequest.php#672 (show)
public function getRequest()
{
    return $this->_request;
}

remove() method
public mixed remove(integer $name)
$name integer the index of the item to be removed.
{return} mixed the removed item.
Source Code: framework/web/CHttpRequest.php#728 (show)

    {
        if($this->_initialized)
            $this->removeCookie($cookie);
    }
    return $cookie;
}

Removes an item at the specified position. This overrides the parent implementation by performing additional cleanup work when removing a TCookie object.

removeCookie() method

$cookie CHttpCookie cook to be deleted
Source Code: framework/web/CHttpRequest.php#757 (show)
protected function removeCookie($cookie)

        setcookie($cookie->name,null,0,$cookie->path,$cookie->domain,$cookie->secure,$cookie->httpOnly);
