Url

Provides URL related helper methods.

This class provides simple methods that can be used to parse and modify the current URL. It is most useful when plugins need to redirect the current request to a URL and when they need to link to other parts of Matomo (formerly Piwik) in HTML.

Examples

Redirect to a different controller action

public function myControllerAction()
{
    $url = Url::getCurrentQueryStringWithParametersModified(array(
        'module' => 'DevicesDetection',
        'action' => 'index'
    ));
    Url::redirectToUrl($url);
}

Link to a different controller action in a template

public function myControllerAction()
{
    $url = Url::getCurrentQueryStringWithParametersModified(array(
        'module' => 'UserCountryMap',
        'action' => 'realtimeMap',
        'changeVisitAlpha' => 0,
        'removeOldVisits' => 0
    ));
    $view = new View("@MyPlugin/myPopup");
    $view->realtimeMapUrl = $url;
    return $view->render();
}
