Accessing Arguments using $_GET - atk4

Question

I am adding an email validation step to my user registration. I cannot seem to get access to the arguments that are being passed in the emailed link;
link: activation.php?email=someone#somewhere.com&key=5614c46be05a95f55f2231d8dea41418d17b197a
Here is the page code;
class page_activation extends Page {
function init(){
parent::init();
if($this->api->auth->isLoggedIn())$this->api->redirect('index');
$loginAccount = $_GET['email'];
$activationKey = $_GET['key'];
$this->add('H1')->set('Activated');
$this->add('H3')->set('Account: '.$loginAccount);
$this->add('H3')->set('Key: '.$_GET['key']);
}

Answer 1

var_dump($_GET);
check network tab in inspector to make sure get params are actually passed.
check mod rewrite rules

Answer 2

I have found a solution in case it might help someone. It seems you can access the $_SERVER vars but the $_GET vars are lost by the time you get to the page. Here is some code that I used to accesses the passed vars from the email link;
class page_activation extends Page {
function init(){
parent::init();
if($this->api->auth->isLoggedIn())$this->api->redirect('index');
$data = parse_url($_SERVER['REQUEST_URI'], PHP_URL_QUERY);
$queryParts = split('[;&]', $data);
$params = array();
foreach ($queryParts as $param) {
$item = explode('=', $param);
$params[$item[0]] = $item[1];
}
$loginAccount = $params['email'];
$activationKey = $params['key'];
$this->add('H1')->set('Activated');
$this->add('H3')->set('Account: '.$loginAccount);
$this->add('H3')->set('Key: '.$activationKey);
}
}
