不顯示錯誤頁面

Question

我想弄清楚爲什麼當一個userID和/或registrationKey沒有放入URL中時，它不顯示404錯誤頁面。應該發生什麼情況是激活控制器被加載時，它應該查看userID和registrationKey是否在URL中，如果不是，則轉到錯誤頁面。

} 

public function index($userID = NULL, $registrationKey = NULL)

    //Config Defaults Start 
    $msgBoxMsgs = array();//msgType = dl, info, warn, note, msg

任何想法？

我認爲代碼看起來很好，但是您可能需要對自己的問題進行一些解決。如果你不通過你的URI傳遞參數，並且show_404（）函數沒有被調用，那麼你需要看看這些變量包含什麼。由於userID不是數字或registrationKey不僅僅是字母數字。如果你在他們之前var_dump聲明，並且不通過你的URI參數，會發生什麼？
