php - Generating a shortcode from value of input

Question

So what I'm trying to do is to make a plugin where the user can input anything in a input field and then it uses the given "uid" to make a short code.

So when i type in [text_field_1] somewhere, it'll refer to what is written in that field.

So there's a fixed amount of fields that i determine, so it doesn't need to generate new fiels and so on, so far it works except for the shortcode part, i have no idea where to go, I've tried a few different solutions, but without luck. Kept giving me errors... :) I'm also very very new to this, so this might be way over thought.

Appreciate any help out there!
