I have this simple session class
class Session
{
public static function init() {
@session_start();
}
public static function set($key, $value) {
$_SESSION[$key] = $value;
}
public static function get($key) {
if (isset($_SESSION[$key]))
return $_SESSION[$key];
}
public static function destroy() {
unset($_SESSION);
session_destroy();
}
}
In my other class I have
public function verifyFormToken($form)
{
// check if a session is started and a token is transmitted, if not return an error
if(!isset(Session::get($form.'_token'))){
return false;
}
// check if the form is sent with token in it
if(!isset($data['token'])) {
return false;
}
// compare the tokens against each other if they are still the same
if (Session::get($form.'_token') !== $data['token']) {
return false;
}
return true;
}
I can set a session no problem but when I come to get it using verifyFormToken()
, i get this error message
Can't use function return value in write context
which points to this line
if(!isset(Session::get($form.'_token'))){
