php - 移动浏览器无法登录我的网站

Question

我已经使用手机附带的“通用”浏览器在 2 种手机型号上测试了我的网站，但遗憾的是，每次我尝试登录时，它都会让我返回到我的索引页面。

这是我的登录码

    <form name='login' method='POST' action='authentication.php'>
<table border=0 cellpadding=2>
<tr><td>Login:</td><td></td></tr>
<tr><td>E-mail: </td><td><input type=text name='email' id='email' size=20 maxlength="200"></td></tr>
<tr><td>Password: </td><td><input type=password name='password' id='password' size=20 maxlength="100"></td></tr>
<tr><td></td><td><input type=submit value='Login'></td></tr>
</table></form>

这是 authentication.php(片段)

$currentUserEmail = $_POST["email"];
$currentUserPwd = md5($_POST["password"]);
$stmt = $dbi->prepare("select status from users where email=? and pwd=?");
$stmt->bind_param('ss', $currentUserEmail,$currentUserPwd); 
mysqli_stmt_execute($stmt);
mysqli_stmt_store_result($stmt);
$isUserAvailable = mysqli_stmt_num_rows($stmt);
$stmt->bind_result($getUserStatus);
$stmt->execute() or die (mysqli_error());
$stmt->store_result();
$stmt->fetch();
$stmt->close();

if($isUserAvailable > 0){
    if ($getUserStatus == "PENDING") {
        $userIsLoggedIn = "NO";
        $registeredUser = "NO"; 
        unset($userIsLoggedIn);
        setcookie("currentMobileUserName", "", time()-3600);
        setcookie("currentMobileUserEmail", "", time()-3600);
        setcookie("currentMobileSessionID", "", time()-3600);
        setcookie("currentMobileUID", "", time()-3600);
        header('Location: '.$config['MOBILE_URL'].'/index.php?error=2&email='.$currentUserEmail);
    }elseif (($getUserStatus == "ACTIVE") || ($getUserStatus == "active")){ //means successfully logged in

        //set the cookie

        setcookie("currentMobileUserName", $currentUserName, $expire);
        setcookie("currentMobileUserEmail", $currentUserEmail, $expire);
        setcookie("currentMobileSessionID", $getGeneratedMobileUSID, $expire);
        setcookie("currentMobileUID", $currentUID, $expire);
        $userIsLoggedIn = "YES";
        $registeredUser = "YES";


        $result = $stmt->execute() or die (mysqli_error($dbi));

        if ($caller == "indexLoginForm"){
            header('Location: '.$config['MOBILE_URL'].'/home.php');
        }else{

            header('Location: '.$config['MOBILE_URL'].'/home.php');

        }


    }

}else{
    $userIsLoggedIn = "NO";
    $registeredUser = "NO"; 
    unset($userIsLoggedIn);
    setcookie("currentMobileUserName", "", time()-3600);
    setcookie("currentMobileUserEmail", "", time()-3600);
    setcookie("currentMobileSessionID", "", time()-3600);
    setcookie("currentMobileUID", "", time()-3600);
    header('Location: '.$config['MOBILE_URL'].'/index.php?error=1');

}

我访问移动网站的唯一方法是使用 opera mini。仅供引用，我测试我的网站时使用的两个“通用浏览器”都支持 cookie(至少浏览器设置是这么说的)。

谢谢

一些移动浏览器(我想到了黑莓)除了 2xx 响应之外不处理任何发送的 cookie - 您正在使用 302 重定向进行响应。

试试这个:

setcookie("currentMobileUserName", $currentUserName, $expire);
setcookie("currentMobileUserEmail", $currentUserEmail, $expire);
setcookie("currentMobileSessionID", $getGeneratedMobileUSID, $expire);
setcookie("currentMobileUID", $currentUID, $expire);
$userIsLoggedIn = "YES";
$registeredUser = "YES";
... // some WML/HTML markup...
print "You are logged in. Click <a href='" 
       . $config['MOBILE_URL']. "/home.php'>here</a> to continue.";

此外，一些较旧的设备不喜欢在每个站点保存多个 cookie - 解决这个问题有点复杂，假设您需要一个可用的永久标识符，这样用户就不必登录(生成您的自己的 session ID 加密 token ，该 token 用时间标识用户并设置 future 的到期时间 - 如果没有找到匹配的 session ID，则解密以获取记住我的值)。
