How to auto-update related post when editing a recipe

Hi there,

I would have to recommend hooking into the save_post WordPress hook. You can then check if the post being saved has the wprm_recipe post type to then get the parent post of that recipe. Something like this should work:

function wprm_update_parent_post_on_save( $post_id, $post ) {
	if ( 'wprm_recipe' === $post->post_type ) {
		$parent_post_id = get_post_meta( $post_id, 'wprm_parent_post_id', true );

		if ( $parent_post_id ) {
			wp_update_post( array(
				'ID' => $parent_post_id,
			) );
		}
	}
}
add_action( 'save_post', 'wprm_update_parent_post_on_save', 10, 2 );

Take note that I have not tested this exact code.

Kind regards,
Brecht

Brecht,

Thank you for the code, however, it didn’t work. What is expected is that the parent post is edited and saved and then that post should be the first post (at top) on the home page. The code to show that post as first on the home page is already there. It seems that your code did not make the edit/save of the parent post as intended. But thanks for looking at it.

I just tested that code and it does trigger an update of the parent post on my test site.

You might need to update the post_date in wp_update_post, to have it show up at the top.
