Is it possible to get the shortcode of a Wordpress page?

Question

Laravel

To create a page, I use two constructors. I would like to use one of the widgets of one constructor in another. I thought it could be done with a shortcode. Is it possible?
PS Maybe there is an easier way than I'm trying to find?

Answer 1

If I understand correctly, then

$postsIds = WatchList::where('user_id', Auth::user()['id'])->get()->pluck('post_id')->toArray();

Answer 2

Is there an easier way than what I'm trying to find?

Do not use constructors, especially two at once on one site.
