    Linking a form to an external DB

    Asked by mdavid on October 06, 2016 at 06:31 PM

    Is there a way to link a field on a form to an external DB?  For example, a user enters a user ID and the form then retrieves information from the external DB and displays it on the form.

    Unfortunately, this is currently not possible within JotForm.

    You will need to add a custom program code to implement the logic on your form. What you can do is to download the full source code of the form and modify it as needed to implement the logic you want.

    Another options will be to create a PHP code that will retrieve the data from the link you have provided and then pre-populate the form using URL parameter.

    You can check this thread also which has a similar discussion on the requirement.

    Do let us know if you need further assistance.
