Cookies are a mechanism for storing data in the remote browser and thus tracking or identifying return users.
Sets the value of cookie with configuration.
Cookie::set($name, $value, $expiry = 90, $path = null, $domain = null, $secure = false, $httpOnly = false); // Cookie::set('MyApplicationPreference', 'Yes');
Returns the value of cookie.
Cookie::get($name); // Cookie::get('MyApplicationPreference'); // returns 'Yes'
Clears a given cookie.
Cookie::force_expiry($name, $path = null, $domain = null); // Cookie::force_expiry('MyApplicationPreference')
The Cookie class manipulates and sets cookies using a Cookie_Backend. The backend is in charge of the logic that fetches, sets and expires cookies. By default we use a CookieJar backend which uses PHP's setcookie function.
The CookieJar keeps track of cookies that have been set by the current process as well as those that were received from the browser.
$myCookies = array( 'cookie1' => 'value1', ); $newBackend = new CookieJar($myCookies); Injector::inst()->registerService($newBackend, 'Cookie_Backend'); Cookie::get('cookie1');
Assuming that your application hasn't messed around with the
$_COOKIE superglobal, you can reset the state of your
Cookie_Backend by simply unregistering the
CookieJar service with
Injector. Next time you access
create a new service for you using the
Injector::inst()->unregisterNamedObject('Cookie_Backend'); Cookie::get('cookiename'); // will return $_COOKIE['cookiename'] if set
Alternatively, if you know that the superglobal has been changed (or you aren't sure it hasn't) you can attempt to use
CookieJar service to tell you what it was like when it was registered.
//store the cookies that were loaded into the `CookieJar` $recievedCookie = Cookie::get_inst()->getAll(false); //set a new `CookieJar` Injector::inst()->registerService(new CookieJar($recievedCookie), 'CookieJar');
Using your own Cookie_Backend
If you need to implement your own Cookie_Backend you can use the injector system to force a different class to be used.
Name: mycookie After: '#cookie'
Injector: Cookie_Backend: class: MyCookieJar
