Edit: Yes, I know, I provided an answer to this question myself. However, I’m still interested in other solutions and/or comments on the one I found. Is this how you would do this? Are there any other ways?
I would like to provide some additional description and on-page help (i.e., no contextual help or help tabs) on the overview page (i.e., edit.php
) for a custom post type.
According to edit.php
(as well as class-wp-list-table.php
and class-wp-posts-list-table.php
) there is no appropriate hook.
So, how can I do this?
A few notes:
- I came up with a solution, which I would describe a bit hackish, so I’m open for a clean solution (if there is one);
- I will post my solution as an answer so you can comment on that (and so the question and answer are kept separate);
- I’m aware that I can do this via JavaScript/jQuery – but that’s not clean (IMO) as well…

I kind of feel like I’m missing something obvious, but maybe I’m not. What about the admin_notices
hook, seems like the obvious choice to me. There are some admin CSS classes available you can use, like updated
, error
or update-nag
, or you can of course add your own styles, like asked and answered here or here.
Code:
<?php
function my_cpt_info() {
if ('edit-my_cpt' === get_current_screen()->id) {
?>
<div class="updated">
<p>
<?php _e('Some information about my CPT...', 'my-text-domain'); ?>
</p>
</div>
<?php
}
} // function my_cpt_info
add_action('admin_notices', 'my_cpt_info');
?>
