Formidable Forms is another cool WordPress form plugin. Initially, as a developer I was resistant to use any form plugins because I wanted to be able to manage the code. It turned out, though, that those form builder plugins save a ton of time. Thanks Ryan :)

Here's a 1min video with some explanations how to pre-populate a field value dynamically.

Then you will need to link to the page that has your form and pass the parameter you’ve used above e.g. example.com/contact/?qc_email=me@example.com

When you're linking to the form page do make sure that all the passed parameters are URL encoded (using php's urlencode function or an online service that does that to ensure all the data is correctly passed).

Pre-populating form fields is a good thing. That way you don’t have to make your users type additional information if you already have it stored somewhere (cookies or database). In our case when the user wanted to contact us regarding a product (support or a pre-sale question) to pre-populate the product name in the form.

In this post I showed you how to do it for one field. You can do it for all the form fields you have. It's just an extra effort but totally worth it. Another thing that we use is to partially pre-populate the message in case the potential client want's to ask some pre-sale questions.
