Hi @leuchterits
I believe you can do it by using the acf/save_post hook. But, instead of creating a post, you need to create a user using the wp_create_user() function and delete the newly created post using the wp_delete_post() function. Maybe something like this:
function my_acf_save_multiple_posts( $post_id ) {
// get the user name field
$first_name = get_field('first_name', $post_id);
// get the user name field
$last_name = get_field('last_name', $post_id);
// create the user
wp_create_user( $first_name . "_" . $last_name, 'random password here' );
// delete the unused post
wp_delete_post($post_id);
}
// run after ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_multiple_posts', 20);
I hope this makes sense 🙂
