    Is there any way to pass pre-recieved data into a form?

    Asked by asunwatcher on October 10, 2010 at 10:48 AM

    I'm asking the user to select a postcode area using an image map - is there any way to feed this to my form as a hidden field to then be saved?



    User sees image map of London > Selects a postcode > Jotform records postcode> Presents the rest of the form to be filled in...

    Yes, it is possible to pre-populate a form with data passed from your own site. Simply add "?fieldname=value&" to the URL of a form.  Here is an example:


    To find out what is the field name for a particular question, you must look up the source code of the form using browser's "Source" option.

    Can I get some help with this?

    I am trying to link to my form in my contact page, so I want the contact page to open with the form pre-filled, not just the form in a blank browser window.

    Do I replace the "www.jotform.com" with my own site address?

    Obviously I change the number to my own form number. I haven't even started on the pre-filled fields yet, which I hope to be fed from a third party CMS.

    You can get your form URL by clicking on "Preview" button on the form builder, or by clicking "Embed Form" button on the toolbar. Then you can add the fields as described there.
