Display post meta on edit page in admin

Question

I've got a custom post type for contact form submissions. I'm using the JSON API, so these form submissions get posted directly to WordPress.

I've got it to display custom meta columns (e.g. first name, last name, email address) in the admin, however I now need it to show these columns in the edit page.

Note, I only need to output these columns, not have them displayed in form fields.

How do I do this?

Answer 1

I found the answer:

add_action('add_meta_boxes', 'add_contact_form_meta_box');

function add_contact_form_meta_box() {
    add_meta_box('contact-form-meta-box-id', 'Submission Data', 'contact_form_meta_box', 'contact_form', 'normal', 'high');
}

function contact_form_meta_box($post) {
    echo get_post_meta($post->ID, 'first_name', true);
}
