javascript - $.post 和 AJAX 在服务器上不工作，但在本地主机上工作正常

Question

我刚把我的网站移到服务器上，结果很震惊，$.post() 并且 AJAX 在服务器上不工作。

$.post() 总是返回空白数据。在这种情况下，您可以查看下面的 $.post() 示例，当我 alert(info) 它显示 Array() 时:

$(document).ready(function () {
    $("#faq").submit(function () {
        var data = $(this).serializeArray();
        $.post("worker.php", data, function (info) {
            $(".faq_status").fadeOut();
            $(".faq_body").prepend(info);
        });
        return false;
    });
});

所有 $.post() 和 AJAX 代码都发生了同样的事情。我不知道该怎么办。

这是我的 worker.php 进度:

$question = addslashes(htmlentities($_POST['user_question']));
$uip = $_SERVER['REMOTE_ADDR'];

if ($question == "") {
    echo "<p class='alert alert-danger faq_status'>Problem in posting your query. Please resubmit it.</p>";
    exit;
}

$day = date('d');
$month = date('m');
$year = date('Y');

$sql = "SELECT no FROM user_faq WHERE user_ip = '$uip' AND EXTRACT(MONTH FROM asked_time) = $month AND EXTRACT(DAY FROM asked_time) = $day AND EXTRACT(YEAR FROM asked_time) = $year";

$record = $conn->query($sql);

if ($record->rowCount() >= 2) {
    echo "<p class='alert alert-danger faq_status'>Problem in posting your query. please resubmit it.</p>";
} else {
    $sql = "INSERT INTO `user_faq`(`no`, `question`, `user_ip`,`asked_date`) VALUES (NULL,:que,:ip,Now())";

    $query = $conn->prepare($sql);
    $query->bindValue(":que", $question, PDO::PARAM_STR);
    $query->bindValue(":ip", $uip, PDO::PARAM_STR);

    try {
        $query->execute();
        echo "<p class='alert alert-success faq_status'>We have receive your question, answer will be posted here soon!</p>";
    } catch (Exception $e) {
        echo "<p class='alert alert-danger faq_status'>Problem in posting your query. please resubmit it.</p>";
    }
}
