Hi,

This appears to do the job. Expanding on the theme of testimonials, it will update the actual WP post title based on two ACF fields, ‘name’ and ‘testimonial’. It will set the title as follows…

NAME – “First 20 characters…”

function my_post_title_updater( $post_id ) {

	if ( get_post_type() == 'testimonial' ) {

		$my_post = array();
		$my_post['post_title'] = get_field( 'name', $post_id ) . ' - "' . substr(get_field( 'testimonial', $post_id ), 0, 30) . '..."';
		
		// Update the post into the database
		wp_update_post( $my_post );

	}

}
 
// run after ACF saves the $_POST['fields'] data
add_action('acf/save_post', 'my_post_title_updater', 20);

You could sharpen up the shortening of the testimonial, but everything I need to solve the challenge I had, seems to be achievable with this code.

For prosperity, I’m using the ‘Custom Post Type UI‘ plugin to register the custom post types.

Thanks for everyones help and input.
