我的PHP联系表单正在向我发送空白消息

HTML:
<form class="contact_form" action="php/mail.php" method="post" name="contact_form">
                            <ul>
                                <li>
                                    <label for="name">Name*</label>
                                    <input type="text"  placeholder="Your Name" required />
                                </li>

                                <li>
                                    <label for="name">Email*</label>
                                    <input type="email" name="email" placeholder="Your email address" required />
                                    <span class="form_hint">Proper format "name@something.com"</span>
                                </li>

                                <li>
                                    <label for="name">Website</label>
                                    <input type="url" name="website" placeholder="Your website" required pattern="(http|https)://.+"/>
                                    <span class="form_hint">Proper format "http://someaddress.com"</span>
                                </li>

                                <li>
                                    <label for="message">Message:</label>
                                    <textarea rows="6" cols="40" name="message" ></textarea>
                                </li>

                                <li>
                                    <button class="submit" type="submit">Send</button>
                                </li>

                            </ul>
                        </form>

HTML

/* Subject and Email Variables */

$emailSubject = 'Contact Form';
$webMaster = 'email@address.com';

/* Gathering Data Variables */

$nameField = $_POST['Name'];
$emailField = $_POST['Email'];
$website = $_POST['Website'];
$messageField = $_POST['Message'];

$body = <<<EOD
<br><hr><br>
Name: $nameField <br>
Email: $emailField <br>
Message: $messageField <br>
EOD;

$headers = "From: $email
";
$headers .= "Content-type: text/html
";
$success = mail($webMaster, $emailSubject, $body, $headers);

/* Results Rendered as HTML */

I think you got typo there, change

$headers = "From: $email
";

to

$headers = "From: $emailField
";

Remember to validate the $emailField to avoid injections!

Update: Now that I can see the actual HTML for the form, there is some problems.

I think for requires and ID field, so you should add one to every field in the form.

You also forgot to set name in the name text field.

Lets add the name attribute in the name field, and add the ID field (which should be done for the other fields also):

<label for="name">Name*</label>
<input type="text"  placeholder="Your Name" required />

to

<label for="name">Name*</label>
<input type="text"  id="name" name="name" placeholder="Your Name" required />

$_POST['Name'] is case-sensetive, so you should change your code so the variables match the names in the html. example:

$nameField = $_POST['Name'];

should be

$nameField = $_POST['name'];

put $nameField = $_POST['Name']; $emailField = $_POST['Email']; $website = $_POST['Website']; $messageField = $_POST['Message']; within a post function. After verifying $_post is not empty. on form submit.

There are more problems, so:

1. you missed name attribute at the name text input
2. you used incorect names, PHP is case-sensitive in keys ($_POST['name'] !== $_POST['Name']). This is the point why you received blank meesages
3. for attribute in labels has to correspond with input ID

Updated code:

<form class="contact_form" action="php/mail.php" method="post" name="contact_form">
    <ul>
        <li>
            <label for="Name">Name*</label>
            <input type="text" id="Name" name="Name" placeholder="Your Name" required />
        </li>

        <li>
            <label for="Email">Email*</label>
            <input type="email" name="Email" id="Email" placeholder="Your email address" required />
            <span class="form_hint">Proper format "name@something.com"</span>
        </li>

        <li>
            <label for="Website">Website</label>
            <input type="url" id="Website" name="Website" placeholder="Your website" required pattern="(http|https)://.+"/>
            <span class="form_hint">Proper format "http://someaddress.com"</span>
        </li>

        <li>
            <label for="Message">Message:</label>
            <textarea rows="6" id="Message" cols="40" name="Message" ></textarea>
        </li>

        <li>
            <button class="submit" type="submit">Send</button>
        </li>
    </ul>
</form>
