You mentioned on the previous thread the following:

Ideally I just want a stand alone form with no navigation and not embedded into an existing website...

If you won't be embedding the form to an existing page/website, then there's no way to fetch the submission data then have it forwarded to your own database.

If your only aim is to access the Submission Data afterwards, you can do that inside your JotForm account.

There are also a variety of reports you can generate in JotForm that you might want to look at.

On the other hand, if you will be using a Custom Thank You page that redirects to an existing page/website that you own, then you can send your submission data to a MySQL DB using PHP.

Here's a guide showing some examples on how to achieve that: How-to-send-Submissions-to-Your-MySQL-Database-Using-PHP Keep in mind that you would need a programmer/developer to do this for you in case you're not one.
