Action hook for post type creation?

Hey @dcutri500

Just to be certain, are you talking about when registering a post type itself? Or do you mean posts within a post type?

For example say that I register a movie post type, and then start publishing horror movies in the post type, and this functionality is supposed to happen per movie, only on initial publish?

Yes, only when the post type itself is created, not for any single post operation.

When the movie post type is created, do something, but only that one time.

So, not per post. I mean not when creating or saving a single post. Just when creating the actual post type on the Add New Post Type screen.

I know we have this action hook:

/**
 * Fires after a post type is updated to our saved options.
 *
 * @since 1.0.0
 *
 * @param array $data Array of post type data that was updated.
 */
do_action( 'cptui_after_update_post_type', $data );

This runs after saving of a new or existing post type. $data would be an array of all the settings, from the submitted form. For example you could get the post type slug from $data['cpt_custom_post_type']['name']

The only part that we don’t have would be a way to limit to just once. That could be easily coded out though for your usecase. Perhaps a quick single row option that stores slugs for which post types have already been run, and if the slug is NOT in the option, your code runs. If it is in there already, return early.

$ran_types = get_option('my-ran-slugs', [] );
if ( in_array( $data['cpt_custom_post_type']['name'], $ran_types ) ) {
	return;
}

// Run your code here.

$ran_types[] = $data['cpt_custom_post_type']['name'];
update_option('my-ran-slugs', $ran_types );

Thank you so much! That looks really promising. I will let you know how it turns out.

Thanks again, Michael. This is working perfectly for me.

So, whenever a new post type is registered, check a box on the theme options page:

// Check the box for a new post type on theme options page
function check_post_type_box_initially($data) {

	// Get the post types that are already checked
	$checked = get_checked_post_types();

	// Get the post types that have already been registered
	$already_registered = get_option('already_registered', []);

	// Don't do anything for those post types that are not new
	if ( in_array( $data['cpt_custom_post_type']['name'], $already_registered ) ) {
		return;
	}

	// This is a new post type: add it to the checked and already registered arrays
	$checked[] = $data['cpt_custom_post_type']['name'];
	$already_registered[] = $data['cpt_custom_post_type']['name'];

	// Update the database
	update_option('options_post_type_options_post_types', $checked);
	update_option('already_registered', $already_registered, 'yes');

}
add_action( 'cptui_after_update_post_type', 'check_post_type_box_initially' );

Looks like a winner to me.

Glad something was able to be done here.

Let us know if you need anything else.
