How to create a collection that the website member can edit.

Hello,
I’m trying to create a form database collection, where anyone on the website once they fill up the form they will automatically redirect on the sign up website member.
Because I would like to create on the page member a buttom where they can view their applicatio id and edit.

  • Right now I’ve created a collection with the permission that anyone can create. I would like to know how to code that before my customer submit the form he will sign up or login on the member website, in this way next time he log in will be able to edit his form.

  • Also I would like the possibility to my user to view or download the document uploaded on the collection. Which element I can put on my read only form to view the or download the documents?

Right now I’m creating the second member only profile page with the collection of the application instead the one of the member.
