表单AJAX PHP电子邮件发送问题 - Form AJAX PHP email sending problems

这是我使用的代码:

HTML:

        <form id="ajax-contact" method="post" action="mailer.php">
            <div class="field">
                <label for="name">Name:</label>
                <input type="text" id="name" name="name" required>
            </div>
            <div class="field">
                <label for="email">Email:</label>
                <input type="email" id="email" name="email" required>
            </div>
            <div class="field">
                <label for="message">Message:</label>
                <textarea id="message" name="message" required></textarea>
            </div>
            <div class="field">
                <button type="submit">Send</button>
            </div>
        </form>
    </div>

JS:

$(function() {
// Get the form.
var form = $('#ajax-contact');
// Get the messages div.
var formMessages = $('#form-messages');
// Set up an event listener for the contact form.
$(form).submit(function(e) {
    // Stop the browser from submitting the form.
    e.preventDefault();
    // Serialize the form data.
    var formData = $(form).serialize();
    // Submit the form using AJAX.
    $.ajax({
        type: 'POST',
        url: $(form).attr('action'),
        data: formData
    })
    .done(function(response) {
        // Make sure that the formMessages div has the 'success' class.
        $(formMessages).removeClass('error');
        $(formMessages).addClass('success');
        // Set the message text.
        $(formMessages).text(response);
        // Clear the form.
        $('#name').val('');
        $('#email').val('');
        $('#message').val('');
    })
    .fail(function(data) {
        // Make sure that the formMessages div has the 'error' class.
        $(formMessages).removeClass('success');
        $(formMessages).addClass('error');
        // Set the message text.
        if (data.responseText !== '') {
            $(formMessages).text(data.responseText);
        } else {
            $(formMessages).text('Oops! An error occured and your message could not be sent.');
        }
    });
});
});

PHP:

<?php
// Only process POST reqeusts.
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Get the form fields and remove whitespace.
    $name = strip_tags(trim($_POST["name"]));
            $name = str_replace(array("'r","'n"),array(" "," "),$name);
    $email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);
    $message = trim($_POST["message"]);
    // Check that data was sent to the mailer.
    if ( empty($name) OR empty($message) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) {
        // Set a 400 (bad request) response code and exit.
        http_response_code(400);
        echo "Oops! There was a problem with your submission. Please complete the form and try again.";
        exit;
    }
    // Set the recipient email address.
    // FIXME: Update this to your desired email address.
    $recipient = "stackoverflow@gmail.com";
    // Set the email subject.
    $subject = "New contact from $name";
    // Build the email content.
    $email_content = "Name: $name'n";
    $email_content .= "Email: $email'n'n";
    $email_content .= "Message:'n$message'n";
    // Build the email headers.
    $email_headers = "From: $name <$email>";

    // Send the email.
    mail($recipient, $subject, $email_content, $email_headers);
    if (mail($recipient, $subject, $email_content, $email_headers)) {
        // Set a 200 (okay) response code.
        http_response_code(200);
        echo "Thank You! Your message has been sent.";
    } else {
        // Set a 500 (internal server error) response code.
        http_response_code(500);
        echo "Oops! Something went wrong and we couldn't send your message.";
    }
} else {
    // Not a POST request, set a 403 (forbidden) response code.
    http_response_code(403);
    echo "There was a problem with your submission, please try again.";
}
?>

使用这个代码，我得到了成功消息，但我没有收到电子邮件。服务器支持邮件功能。如果我只是添加一个示例函数:

mail( "stackoverflow@gmail.com", "dummy", "hi!" );

作为第一行我确实收到了这封邮件

您尝试实例化的每个对象都不正确。试试

var a = $('#myId'); // a jquery object
// you dont need to pass it again as $(a) this is wrong 
// use below instead of $(a)
// right way to call method in jquery change you every instance
a.submit(function (e) { 
  // your code ....
});

$headers[] = "MIME-Version: 1.0";
$headers[] = "Content-type: text/plain; charset=iso-8859-1";
$headers[] = "From: Sender Name <sender@domain.com>";
$email_headers = implode("'r'n", $headers);
