We organise trainings and for every training I have a different websitepage. I want to add a form, so people can easily leave their details (often they aren't in our contacts yet). Instead of having to create a form for every page, I want to create one form which also shows the URL when the form is submitted.
So if someones fills in the training on the page of Training A, I can see the url, so I know they subscribed for Training A. And of course the same for Training B, C etc.
How can I do this?
Good to know: We have our website built in Hubspot CMS. I have limited knowledge of development. I understand the 'hidden field' however I don't know how to add the url here.
