我的联系表单不起作用

我从房东那里收到了我的联系表格的这个代码

<?php
$request_method = $_SERVER["REQUEST_METHOD"];
if($request_method == "GET")
{
    $query_vars = $_GET;
} 
elseif ($request_method == "POST")
{
    $query_vars = $_POST;
}
reset($query_vars);
$t = date("U");
$file = $_SERVER['DOCUMENT_ROOT'] . "'ssfm'gdform_" . $t;
$fp = fopen($file,"w");
while (list ($key, $val) = each ($query_vars)) 
{
    fputs($fp,"<GDFORM_VARIABLE NAME=$key START>'r'n"); 
    fputs($fp,"$val'r'n");
    fputs($fp,"<GDFORM_VARIABLE NAME=$key END>'r'n");
    if ($key == "redirect") 
    { 
        $landing_page = $val;
    }
}
fclose($fp);
if ($landing_page != "")
{
    header("Location: http://".$_SERVER["HTTP_HOST"]."/$landing_page");
} 
else 
{
    header("Location: http://".$_SERVER["HTTP_HOST"]."/");
}
?>

我决定使用这个

<?php 
if ($_POST['parse_Var'] == "test_contact") {
    $email_title = 'New Email From Your Website';
    $my_email = 'alexeisrico@gmail.com';
    $email_field = $_POST['email'];
    $name_field = $_POST['name'];
    $message_field = $_POST['message'];
    $body = <<<EOD
<br><hr><br>
    Email: $email_field <br/>
    Name: $name_field <br/>
    Message: $message_field <br/>
EOD;
    $headers = "From: $email_field'r'n";
    $headers .= "Content-type: text/html'r'n";
    mail("$my_email", "$email_title", "$body", "$headers");
    header("location: http://www.phweshdeals.com/thanks.html");
}
?>

这是我带有PHP扩展名的HTML表单

<form action="config/test_contact.php" method="post">
                <ul>
                    <li><label for="name">Name:</label></li>
                    <li><input id="name" class="field" name="name" value="<?php print "$name_field"; ?>" placeholder="enter your name..." type="text" required><em>*required</em></li>

                    <li><label for="email">Email:</label></li>
                    <li><input id="email" class="field" name="email" value="<?php print "$email_field"; ?>" placeholder="enter your email..." type="email" required><em>*required</em></li>

                    <li>
                        <label for="message">Your Message</label>
                    </li>
                    <li>
                        <textarea id="message" name="message" value="<?php print "$messgae_field"; ?>" autocomplete="on" placeholder="type your message here..."></textarea><em>*required</em>
                    </li>

                    <li><input type="checkbox" required></li>
                    <li class="confirm">Confirm you are NOT a spammer</li>
                    <li><input type="submit" value="submit" style="background-color:#287472;
                        color:#fff;text-shadow:1px 1px #000; text-transform:uppercase;
                         font-weight:bold; border-radius:5px;"
                      id="submit_button"></li>
                      <input type="reset" value="clear!" style="background-color:#287472;
                        color:#fff;text-shadow:1px 1px #000; text-transform:uppercase;
                         font-weight:bold; border-radius:5px;"
                      id="reset_bg">
                </ul>
                <input type="hidden" name="parse_Var" id="parse_Var" value="test_contact">
        </form>

如果我使用我的主机的 PHP 代码，它不会捕获客户端填写表单时我想捕获的所有输入字段。我决定创建我的，它甚至根本不起作用。如果我点击提交，我会在浏览器中收到此消息;"未指定输入文件。"

我尝试了不同的 php 表单格式，但对我不起作用。问题可能出在我的主机上吗？顺便说一下，这是我的主人;www.websitepalace.com .我已经联系了他们，但我无法得到任何切实的解决方案。我还听到一些主机故意这样做，以控制/防止他们的客户向人们发送垃圾邮件或其他东西。不退出清除。拜托，我需要你的帮助。
