Add a label to the editor?

Question

I'm working on a custom post type. I have the editor enabled but the content that will go in that box is secondary and it isn't clear what should be typed there so I want to add a label for the editor. How do I do that?

Answer 1

I recently used this in one of the projects, so here you go

add_action( 'edit_form_after_title', 'wp692_edit_form_after_title' );

function wp692_edit_form_after_title() {
echo '<h2>This is My Label!</h2>';
}

Answer 2

After hacking around, this is the solution I came up with:

At the top of functions.php I have the following line:

add_action('admin_footer', 'add_title_to_editor');

Just thrown in the middle of functions.php I have the following function:

function add_title_to_editor() {
    global $post;
    if (get_post_type($post) == 'my_custom_post_type') : ?>
        <script> jQuery('<h3>Optional Additional Information</h3>').insertBefore('#postdivrich'); </script>
    <? endif;
}
