Question

我在服务器上的登录（apache）不起作用，但我确实让它在本地工作（WAMP）。我已经尝试使用我的WAMP服务器的数据库并且也可以，但是一旦文件或服务器上它停止工作。我检查了所有链接并且它们是正确的。服务器没有提供任何错误消息，它只是继续返回同一页面（not_logged_in.php）。

我使用的代码如下：

的index.php

<?php
require_once('../includes/additions/initialize.php');
require_once(FUNCTIONS);
require_once(SESSION);  

// ... ask if we are logged in here:
if (logged_in()) {
    // the user is logged in
   include(ADDITIONS."logged_in.php");

} else {
    // the user is not logged in
   include(ADDITIONS."not_logged_in.php");
}
?>

logged_in（）函数如下：

function logged_in() {
    // confirm logged in
    return isset($_SESSION['restaurant_user_id']); // restaurants
}

然后转到not_logged_in.php，其中包含以下代码：

<?php require_once(VALIDATION);?>
<?php require_once(HEADER);?>

<?php

$user_name = "";

if (isset($_POST['submit'])) {
    // process the form

    $required_fields = array('user_name', "password" );
    validate_presences($required_fields);

    if (empty($errors)) {
        // attemt login
        $user_name = mysql_prep($_POST["user_name"]);
        $password = mysql_prep($_POST["password"]);

        $found_user = attempt_login_restaurant($user_name, $password);


            if ($found_user) {
            // Success 
            // Mark user as logged in
            $_SESSION["restaurant_user_id"] = $found_user["restaurant_user_id"];
            $_SESSION["email_address"] = $found_user["email_address"];
            $_SESSION["user_name"] = $found_user["user_name"];

            $_SESSION["message"] = "Welcome ". htmlentities($_SESSION["user_name"]) . ", you are now logged in";

            redirect_to(WEBSITE_ROOT. "index.php");

        } else {
            $_SESSION["message"] = "E-mail/password not found.";

}   }       }else {}

echo message();
echo form_errors($errors);
?>
<div id="mainContent" class="fluid">
<div class="restaurantphoto">
<div class="width">

<section class="login">
<form method="post" action="<?php echo WEBSITE_ROOT; ?>index.php">
    <label for="user_name"><?php echo WORDING_USERNAME; ?></label><br />
    <input id="user_name" type="text" name="user_name" value="<?php echo  htmlentities($user_name); ?>" required /><br />
    <label for="user_password"><?php echo WORDING_PASSWORD; ?></label><br />
    <input id="user_password" type="password" name="password" autocomplete="off" required />
    <input type="submit" name="submit" value="<?php echo WORDING_LOGIN; ?>" />
    <br /><br />
</form>
<br />
<a href="<?php echo ADDONS; ?>password_reset.php"><?php echo     WORDING_FORGOT_MY_PASSWORD; ?></a> 
</section>
</section>
</div>
</div>

<?php include(FOOTER); ?>

这里使用的功能是：

function has_presence($value) {
// check if it is not empty
return isset($value) && $value !== "";
}

function validate_presences($required_fields) {
global $errors;
foreach ($required_fields as $field) {
    $value = trim($_POST[$field]);
    if (!has_presence($value)) {
            $errors[$field] = fieldname_as_text($field) . " can't be blank";
        }   }
}
function find_restaurant_by_email($email) {
global $db;

$safe_email = mysqli_real_escape_string($db, $email);

$query = "SELECT * ";
$query .= "FROM database_restaurants ";
$query .= "WHERE email_address = '{$safe_email}' ";
$query .= "LIMIT 1";
$user_set = mysqli_query($db, $query);
// test if there is a query error
confirm_query($user_set);
if ($user = mysqli_fetch_assoc($user_set)) {
return $user;
} else {
    return null;
}
}

function find_restaurant_by_user_name($user_name) {
global $db;

$safe_user_name = mysqli_real_escape_string($db, $user_name);

$query = "SELECT * ";
$query .= "FROM database_restaurants ";
$query .= "WHERE user_name = '{$safe_user_name}' ";
$query .= "LIMIT 1";
$user_set = mysqli_query($db, $query);
// test if there is a query error
confirm_query($user_set);
if ($user = mysqli_fetch_assoc($user_set)) {
return $user;
} else {
    return null;
}
}

function attempt_login_restaurant($login_info, $password) {
// restaurants
$user = find_restaurant_by_email($login_info);
if (!$user) {   
    $user = find_restaurant_by_user_name($login_info);
}
if ($user) {
    // found user, now check password
    if (password_check($password, $user["password"])) {
        // password matches
        return $user;
    } else {
        return false;
    }
} else {
    // admin not found
    return false;
}
}

function password_check($password, $existing_hash) {
// existing hash contains format and salt at start
$hash = crypt($password, $existing_hash);
if ($hash === $existing_hash) {
    return true;    
} else {
    return false;
}
}

因为它也没有反映网站上的消息，我认为在if（空（$ errors））语句之前出现了问题或者会话出现了问题（是的我确实开始了会话，它在session.php文件中）。奇怪的是，一切都在当地工作得很好。我希望你们能帮忙，这真的让我头晕目眩!!

提前致谢！

登录服务器不起作用，在本地它
