WordPress表单操作错误

I have custom coded a form in WordPress, and I am using PHP to handle the submission.

I followed this tutorial, Handling POST Requests the WordPress Way, but on submit I am presented with a blank web page.

Here is my HTML code:

<form method="post" action="<?php echo esc_url(admin_url('admin-post.php')); ?>">
    <input type="hidden" name="action" value="newsletter_signup"/>
    <label for="newsletterEmail">Email:</label>
    <input type="email" name="newsletterEmail" required/>
    <button type="submit" name="newsletterSubmit" value="Submit">
</form>

Here is my PHP code:

function m_newsletter_signup() {
    if (!empty($_POST)) {
        $newsletterEmail = $_POST['newsletterEmail'];

        $to = 'contact@example.com';
        $subject = 'Newsletter Signup';
        $body = "Email: $newsletterEmail";
        $from = 'Website';

        if ($_POST['newsletterSubmit']) {
            if (mail ($to, $subject, $body, $from)) {
                header("Location: https://example.com/site/newsletter-success/");
                exit();
            } else {
                header("Location: https://example.com/site/newsletter-error/");
                exit();
            }
        }
    }
}

add_action('admin_post_nopriv_newsletter_signup', 'm_newsletter_signup');
add_action('admin_post_newsletter_signup', 'm_newsletter_signup');

My form is contained within a .php file within an "inc" folder, and my PHP is contained within functions.php.

I have tried the following:

  • Setting WP_DEBUG within wp-config.php to true (I got zero errors); and
  • I created an "action" folder with a "newsletter.php" file inside it, and changed the action on my form to /action/newsletter.php, but again, I just got the blank web page (this approach worked fine when I tested it on a static website, one without WordPress).

Also, in case it is of relevance, here is a brief overview of the folder structure:

theme
    action
        newsletter.php
    assets
    inc
        form.php
    functions.php

Any advice would be greatly appreciated.

Thanks,

Matthew

P.S. I do not wish to use a plugin as an alternative.
