登錄頁面顯示空白

Question

我當前正在修復的項目的登錄頁面顯示為空白。 我試圖回聲一些話，以找出錯誤所在。 我發現注釋掉下面的代碼即可顯示它。

elseif( isset($_POST['do_login'] ) ){ //Login user

    $email = (isset($_POST['login']) && is_string($_POST['login'])
                && strlen($_POST['login'])<100)?$_POST['login'] : null;
    $password  = (isset($_POST['password']) && is_string($_POST['password'])
                && strlen($_POST['password'])<100)?$_POST['password'] : null;
    $remember  = isset($_POST['chkremember']) ? true : false;

    $result = $auth->login($email, $password, $remember);

    switch($result){
        case 1:
            $msg = 'You have successfully logged in.'
            break;    
        case 2:
            $msg = 'Your account has not yet been confirmed. <br/> Please check the e-mail message sent by us and click the confirmation code to validate this account. <a href="user_login.php?view=resend&resend_email='.$email.'">resend activation e-mail</a>';
            break;
        case 3:
            $msg = 'Your account is not enabled!';
            break;
        case 4:
            $msg = 'Account with given login credentials does not exist!';
            break;
    }
}

誰能幫我弄清楚這段代碼有什么問題嗎？

Answer 1

case 1 ，您錯過了; break前。

Answer 2

 case 1: $msg = 'You have successfully logged in.'   break;
