    Pre-populate fields in my form

    Asked by permissions_books on November 11, 2015 at 05:29 PM

    Hello! How do I have pre-filled data which will remain constant for each request UNLESS the requestor wishes to change something, for example - 


    [click to edit]

    This will allow our customer for one less step to fill in the same address details each time. I currently used the TEXT option however we are not able to see this when the form has been submitted to us.

    Please advise.

    So I used the application to create the URL for me.

    http://form.jotformpro.com/form/53135908199969?format62=Print and Electronic&address[addr_line1]=366%20W.%20Circle%20Drive&address[addr_line2]=Room%20W224A&address[city]=East%20Lansing&address[state]=Michigan&address[postal]=48824&address[country]=United%20States&email=coursematerials%40mail.lib.msu.edu

    ^^ Is that the link that I will send to the customers to fill out?

    Correct, that is the URL pre-fills those specific fields.  When your customers open that link, the fields will contain the appropriate data.

    Great thanks so much - this was super helpful.

    Now another question for you. I don't know if this requires a new thread or not. IF I want to prepopulate fields based on a dropdown option, how do I do that?

    For example, If someone picks PA then the address/phone number and name will auto populate to a Philadelphia Address whereas if they pick FL then that information will switch to FL address.

    Thank You!

    For that, you would use the "Update a form field value" condition":


    Though the guide is a bit outdated, the gist of it should be the same.
