Autopopulate fields from URL

Can your forms auto-populate fields based on a URL string (with parameters)?

For example, if a user clicks on a link on an item page, certain fields will pre-populate based on what item page the user was on.

Let's say it's a shop order form. When the user lands on an item and click to a form, the item name and price would pre-populate on the form if the url for the link was: www.example.com/item1&name=tshirt&price=12USD

The above scenario is completely fictional and not the best example. I just wanted to use a quick example to see if something like this would be possible.

Yes, you can indeed pre-populate form fields with the form URL, this guide will help you doing so: https://www.jotform.com/help/71-Prepopulating-Fields-to-Your-JotForm-via-URL-Parameters 

I hope this helps.
