Question

在我的WordPress中，我在Bootstrap Modal（v4）中有一个带有以下HTML的自定义联系人表单（此tutorial之后）。

<form id="contact-form" action="<?php the_permalink(); ?>" method="post">

<div class="modal-body">
    <?php echo $response; ?>
    <div class="form-group">
        <input class="form-control my-2" type="text" name="message_name" size="50" placeholder="Your full name" value="<?php echo esc_attr($_POST['message_name']); ?>">
        <input class="form-control my-2" type="email" name="message_email" size="50" placeholder="Email address" value="<?php echo esc_attr($_POST['message_email']); ?>">
        <input class="form-control my-2" type="tel" name="message_tel" size="50" placeholder="Country code, Phone number" value="<?php echo esc_attr($_POST['message_tel']); ?>">
        <textarea class="form-control my-2" name="message_text" rows="2" placeholder="Your message" value="<?php echo esc_attr($_POST['message_text']); ?>"></textarea>
        <input  class="form-control my-2" type="text" name="message_human" placeholder="Human check: Enter 2">
    </div>
</div>
<div class="modal-footer">
    <input type="hidden" name="submitted" value="1">
    <button type="submit" value="Submit" class="btn btn-search form-control" id="form-submit">Send Enquiry</button>
</div>

该功能下方，用于验证和阻止表单提交（如果有任何错误）。

//response generation function
$response = "";

//function to generate response
function contact_g_form_response($type, $message) {

global $response;

if ($type == "success") {
    $response = "<div class='message-success text-center'>{$message}</div>";
} else {
    $response = "<div class='message-error text-center'>{$message}</div>";
}
}

//response messages
$not_human = "Enter current year in numbers.";
$missing_content = "Missing something.";
$email_invalid = "Check your Email address.";
$message_unsent = "Message was not sent. Try Again.";
$message_sent = "Thanks! We got your enquiry.";

//user posted variables
$name = $_POST['message_name'];
$email = $_POST['message_email'];
$fromEmail = $name . '<' . $email . '>';
$tel = $_POST['message_tel'];
$text = $_POST['message_text'];
$human = $_POST['message_human'];


//php mailer variables
$to = get_option('admin_email');
$subject = '[General Enquiry] ' . $name . ' | Phone Number:' . $tel;
$headers = 'From: ' . $fromEmail . "\r\n" .
    'Reply-To: ' . $email . "\r\n";

$message = '<html><body><h1>New general enquiry from ' . $name . '!</h1>'
    . '<p>Email: ' . $email . '</p>'
    . '<p>Phone Number: ' . $tel . '</P>'
    . '<p>Inquiry: ' . $text . '</P>'
    . '<p>From page: <b>' . $page . '</b></P>'
    . '<p>Page URL: ' . $url . '</p>'
    . '</body></html>';

if (!$human == 0) {
if ($human != 2) {
    contact_g_form_response("error", $not_human); //not human!
} else {

    //validate email
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        contact_g_form_response("error", $email_invalid);
    } else { //email is valid
        //validate presence of name, phone number
        if (empty($name) || empty($tel)) {
            contact_g_form_response("error", $missing_content);
        } else { //ready to go!
            $sent = wp_mail($to, $subject, $message, implode("\r\n", $headers)); //mail to admin - striptags removing formatting
            // $sent2 = wp_mail($email, $subject, $body, $headers); //mail to visitor
            // if ($sent || $sent2) {
            if ($sent) {
                contact_g_form_response("success", $message_sent); //message sent!
            } else {
                contact_g_form_response("error", $message_unsent); //message wasn't sent
            }
        }
    }
}
} else if ($_POST['submitted']) {
contact_g_form_response("error", $missing_content);
}

在普通HTML页面中使用此代码时，一切都按预期工作。但是，如果将此联系表放在Bootstrap模式中，则会遇到两个问题： 1）验证未发生 2）单击提交按钮后，模态立即关闭

使用下面的代码，我可以防止Modal关闭，但是没有进行验证。

$(document).on('click', '#form-submit', function (e) {
    e.preventDefault();
   });

在提交表单之前，如何验证Bootstrap模式中的联系表单字段？
