I have rows of a contact form. each contact has a different State and Specialty that I want to pass in visible fields in the form when the user clicks the contact button for help.

eg:
id | name | location | specialty | contactbutton
6 | john smith | CA | Podiatrist | contact our service (button pops a modal with the form).

i want the form to look like this:

name: username fill in
email: user fill in
location: CA
specialty: Podiatrist

submit

I will somehow need to grab the correct line based on the id to prefill the fields. I am stuck on how to accomplish this. I can likely attach an ID based on the id in the table to the button that calls the modal. or my thought was to use javascript to get the content from the row and fill it in that way. Any thoughts would be appreciated...
