Enqueueing scripts and styles multiple CPTS

There is a built-in function that you can use, instead of globals. The get_current_screen() function allows you to get the information associated with the current page.

One of its return values is post_type. So you can check against an array of post types to see if anyone matches.

function fhaac_admin_enqueue_scripts(){
    $screen = get_current_screen();
    if (
        in_array( $screen->post_type, array('fhaac','blabla')) &&
        $screen->base == 'post'
     ) { // Do something }
}
