Custom Form Sumissions Collection with an extra column

Hi community, I’d need a Velo code snippet that will add an extra column to a CMS Collection that is created automatically based on form submssions on dynamic pages.

The long story:

I have a collection which contains all product info that I use for the dynamic page. Additionally there is a product identification column with a short product code.

Let’s call this collection PRODUCTS. The relevant column field key is productidentification. (The content of this column I want to see in the collection of form submissions next to each response - based on the dynamic page on which user has filled out and submitted the form)

From PRODUCTS collection I created #dynamicdataset that imports data to the dynamic pages.

On each page there will be a form - so far I understood I need to use input fields with a button instead of a premade Wix form.

I watched/read these tutorials:

  1. https://www.youtube.com/watch?v=M8rt2iqLX9E
    2.get current item dynamic page id and display in user input box - #2 by darak

However, I did not manage to adapt the code for my case.

The tutorial number 2 did not save the information into the collection. Only user input was saved but not the product identification.

Tutorial number 1 I did not manage to adapt the code to be used without a lightbox. I need to have this form directly on the dynamic page.

I’ll be super happy for any help!

Have a great day!
