    Prepopulating form fields fails in iframe embed method

    Asked by zobisatt on August 22, 2015 at 02:45 PM

    Hi! Im following your guides to pre-populate forms using URL Parameters and it works perfectly when I try to pre-populate using the link JotForm generates for my form. But when I try to embed it to my wordpress page using iFrame and follow the same trick, the pre-populate fails. Here is the page where my form is embedded:


    And here is the URL I use to test if the pre-population works:


    Any suggestions?

    Unfortunately, pre-populating fields in iframe embed method is not possible for now. Please use the default embed method instead.

    The only downside of the default embed code is script conflicts, sometimes other Javascript libraries conflict with the form code but please try it and let us know if that happens.

    You can also use our embed form plugin for WordPress: https://wordpress.org/plugins/embed-form/.

    Lastly, I see that you have the website link prepopulated in the URL, you can use our Get Referrer widget if the form is embedded to multiple websites.


    Here's how to add a widget in your form: https://www.jotform.com/help/252-How-to-Add-a-Widget-to-your-Form

    Hi. This is the same person who started the initial thread..I am replying from another account that I created specifically for the client. 

    I have posted a new HTML page on my website with the form embedded as a script as you suggested. On my end, the prepopulating works fine..but for some other users that are testing..the forms opens as normal but the prepopulating fails. Here are the links:
