php - elseif 在用户特定登录中不起作用

Question

我正在尝试设置一个非常基本的登录名，该登录名将根据用户的“类型”（成员或官员）转到两个页面之一。我可以让它为官员工作，或者让它为成员工作，但是当我尝试使用 elseif 时它不能正常工作。我的“官员”用户可以登录，但他会被带到会员页面。我的“会员”用户根本无法登录。谢谢你的帮助。

这是我的代码：

    <?php
    if (!file_exists($userlist) || !is_readable($userlist)) {
    $error = 'There is  a major jam up at the Login Center. Please try again later.';
    } else {
    // read the file into an array called $users
    $users = file($userlist);
     // loop through the array to process each line
     for ($i = 0; $i < count($users); $i++) {
// separate each element and store in a temporary array
$tmp = explode(',', $users[$i]);
// check for a matching record
if ($tmp[0] == $username && $tmp[1] == $password &&  rtrim($tmp[2]) == 'member') {
     $_SESSION['authenticated'] = 'member';
     $_SESSION['start'] = time();
  session_regenerate_id();}

     elseif ($tmp[0] == $username && $tmp[1] == $password &&  rtrim($tmp[2])== 'officer') {
    $_SESSION['authenticated'] = 'officer';
  $_SESSION['start'] = time();
  session_regenerate_id();

  break;
}
      }
    // if the session variable has been set, redirect
    if (isset($_SESSION['authenticated']) || $SESSION['authenticated'] == 'member'){
header("Location: $members_redirect");
exit;}

    elseif (isset($_SESSION['authenticated']) || $SESSION['authenticated'] == 'officer'){
header("Location: $officers_redirect");
exit;


    } else {
$error = 'Invalid username or password.';
   }
   }

Answer 1

You have || (or) instead of && (and)

Try this

if (isset($_SESSION['authenticated']) && $SESSION['authenticated'] == 'member'){
    header("Location: $members_redirect");
    exit;
}
elseif (isset($_SESSION['authenticated']) && $SESSION['authenticated'] == 'officer'){
    header("Location: $officers_redirect");
    exit;
}

Answer 2

You have a missing underscore in your $_SESSION variable in your if and elseif

if (isset($_SESSION['authenticated']) || $SESSION['authenticated'] == 'member')

change to:

if (isset($_SESSION['authenticated']) && $_SESSION['authenticated'] == 'member')

elseif (isset($_SESSION['authenticated']) && $_SESSION['authenticated'] == 'officer')
