邮件和cookie不能一起工作？

Question

请在复制前阅读我的帖子？

昨天有一位开发人员帮我解决了cookie问题，但在添加该代码后，我的表单没有向管理员发送任何邮件并填写表格。我昨天面临的问题是我无法立即访问cookie。

上一个代码：

<?php if(isset($_COOKIE['username']) || isset($_POST['username'])){ ?>
    <script type="text/javascript">
        jQuery(document).ready(function($){
            $('a.down').show().css("display", "block");
        });
    </script>
<?php } else {  include('login.php'); } ?>

我当前的代码：

<?php 
if(!isset($_COOKIE['username'])){
    setcookie("username", $_POST['username'], time() + (86400 * 30), "/");
    $username=$_POST['username'];
}
?>

<?php if (isset($_COOKIE['username']) || isset($username)){ ?>
    <script type="text/javascript">
        jQuery(document).ready(function($){
            $('a.down').show().css("display", "block");
        });
    </script>
<?php } else { include('login.php'); ?>

感谢您的时间。

我的cookie代码现在正在运行，我可以一次提交表单，但问题是我没有收到邮件。

这里是我的login.php文件代码：

<?php if(!isset($_COOKIE['username'])){
        setcookie("username", $_POST['username'], time() + (86400 * 30), "/");
       $username=$_POST['username'];
       }
?>

<?php if (isset($_COOKIE['username']) || isset($username)){ ?>

    <script type="text/javascript">
        jQuery(document).ready(function($){
            $('a.down-resources').show().css("display", "block");
        });
    </script>

<?php } else { 

    if(isset($_POST['submit'])){  

    if(!empty($_POST['username']) && !empty($_POST['email']) && !empty($_POST['phone'])) {

    $username = $_POST['username'];  
    $email = $_POST['email'];
    $phone = $_POST['phone'];
    $company = $_POST['company'];

    if ($username == $_POST['username'] && $email == $_POST['email']){
        if (filter_var($email, FILTER_VALIDATE_EMAIL) === false) {
                echo "$email is not a valid email address";
            }

        $udomain = end(explode('@', $email));
