Prepopulating Fields to Your JotForm via URL Parameters

Last Update: May 26, 2017


Instead of following this guide you can also use this app to generate a prepopulated form URL


Let's say you have a link or a page that should automatically fill in values to your JotForm and you want your form to be prepopulated after being clicked via URL:
Form without prepopulated fields:
Form with prepopulated name fields:

View your form's source to identify each form field name you wish to be prepopulated.  

1. Click the "Preview" button.

2. Click the "OPEN IN NEW TAB" button.


3. Right click on the live form then click "View Page Source" or "Inspect"

Or you can use Browser Inspect Element feature so you can easily identify field names. Check this screenshot.

For text boxes, text area, radio buttons and drop-down menus:

Assuming we are viewing the page source of the form above, let's identify the name of the text boxes first. Field names can be found under the name attribute, e.g. name="q5_fullName[first]"In order to use it on the URL parameter, you only have to copy the name after the underscore symbol "_". (see highlighted code below) 

<input class="form-textbox" type="text" size="10" name="q5_fullName[first]" id="first_5">

<input class="form-textbox" type="text" size="15" name="q5_fullName[last]" id="last_5">

Now we're able to get the names of each field, include them in the URL, remember to put a question mark "?" after the URL to declare that we are submitting parameters, then comes the name followed by equal sign "=", then the value.


If you wish to add more parameters, these are to be separated by "&" sign. 


For Checkboxes:

Identify each checkbox value first.  On our sample form, we have 5 check boxes.  All of these check boxes has the same name, pleasechoose[]

Here's an example check box field for the option "Wood", noticed the name attribute:

<input type="checkbox" class="form-checkbox" id="input_13_1" name="q13_pleaseChoose[]>" value="Wood">

To prepopulate that checkbox via URL parameter:

1. First, find the value of its name attribute in the HTML source code.

2. Copy the name after the underscore symbol "_" e.g  pleaseChoose[] but remove the "[]" on it.

3. Copy the value e.g. Wood

To be able to select more than one, you need to separate each value with a comma.  

Example:,Gold,Metal,Soft drinks,Cheese cake

    Will this work with form embedded using javascript or does there have to be a link to the form?

  • liyam

    Hello parawing742, This will work even as an embedded form using javascript as well.

  • Torm

    Hello, saw the "Dolzy" related prepopulation post, as well.
    New Question:
    Can you suggest the best way I might utilize prepopulation, for taking a registration form submission, comparing the residential part of that information to a database of 450 locations around the USA, and ending up with 3 newly-created PDF pages/files, that each have their own standard layout/formatting, and combine in the form submission info, with the matched database info, so as to display it inside each of the three PDF formatted result pages/files? Clear as mud?

  • JotFormSupport

    Ask your questions to the forum please.

  • jacopogalli

    What about prepopulating the fields of the form that opens inside a lightbox as a Feedback?
    There is an option to set in the javascript:

    new JotformFeedback({
    windowTitle:'Test Form with upload',

  • liyam

    Hello jacopogalli, I have answered your question concerning to lightbox on this link:

  • erussell

    ok when i copy and paste the link to the website the form will not come up. what am I doing wrong?

  • wingsisd

    Can setup a veritable file to read the access file content by url link? Thanks.

  • patriccia

    I have a database with all information that my jotform will be asking the user to fill out in the form. How do I get jotform to access that database when the user type in registration number, so that jotbase will automatically prepopulate the rest of the information.

  • beachy

    Any issues reported with FireFox? Not working for me.

  • FrankA


    is there already a solution for the feedback-widget to get the URL?

    We need to have exact URL from where the feedback was sent. And this URL should be available in the e-mail generated from the submitted form as a value (like field of dropdown, name etc. ...)

    Answers would be appreciated :-D

  • ntnambi

    Hi I have 2 jotforms.
    form 1: user enters their data
    I re-direct to Form 2 and want the First name and Second name from Form 1 to get populated.

    I saw the URL example but is there a way to specify variable name instead of exact value ?

    instead of Dr in the URL below can i substitue a form variable?[prefix]=Dr.

  • ntnambi

    Thanks . I followed it and used it in 2 places
    1. in Autoresponder and the URL comes up with values

    But when I click the above link the new form is not getting populated :(

    2. I gave the same URL in{fullName3:first}&lastName50={fullName3:last}

    This time the form is populated but with variable names {fullName3:first}
    instead of the values

    Pls advice . pls note I have masked the form id by 9999..

  • pepperglobal

    How do I prepopulate based on data that the user submitted from another form? I want to be able to have fields auto-filled from data already entered. Therefore, I thought breaking it into two forms and using the second form in place of a thank you page would be a good approach. I'd like to make the URL of the thank you page (second form) autopopulate based on what the user submitted in the previous form. How do I create a URL for that? Or is there an easier way?

  • scoon

    Hi, I have a form which I have set up sessions with so we can save and come back to later and continue filling in.

    Can I also populate fields from the session url that's provided to the user?

    E.g. user fills in their name on first form and email, autoresponder then sends them an email with the url for second form plus the =session bit, I also then want to prepopulate the user's name from that first form into the second form. Is this possible?

  • billylevine2003gmailcom

  • dpmurphy

    I have setup 3 URL parameters to prepopulate my form. The page hosting page is ASP, so the parameters are inserted at runtime using session variables.

    This is the querystring I'm using with my javascript embedded form:

  • dpmurphy

    Looks like my previous question got truncated. My problem is that the prepopulated email only shows up as gray sample text, and does not pass through the form submission.

  • abcmanagement

    Sorry, I still did not get it.
    First I do not know what values to copy, second, I am going to have many rows and that will be many values and make that line extremely long.

    I tried this and it is not working. Here are the links to form 1: and form 2: here's the URL I placed in the Thank You Custom URL field:{currentName}&membershipNumber={membershipNumber}. Receiving a 405 Not Allowed error

  • bartprescott

    This works really well and I'm using it on my site, BUT!...
    If you enable the "Continue Form Later" feature and set the "Autofill" to enabled, then the fields set via the URL are ignored!
    I'd really like to use both URL populating and autofill enabled. Is there a fix for this?

  • jonathan doughrety

    For the most part the prefill works, but for certain checkmark/bullet points it does not. For example, the following link does not work:[]=CFN

    What is the problem?


  • dorsetholidaylets

    Does this only work with the Jotform Thank you Page or can you create forms which populate another and use IFrame to add both forms to my web site.
    I rather not use the Jotform Thank You page but use a Customized page on my web site.

  • tim

The use would click on an "order print" link which I can use to prepopulate the product name, but I need to pass along an associated image to give the form user a comfort level that what they are buying is the same as what they clicked on in my website

    Apparently the method doesn't work for checkboxes? I tried the link you generated above in the checkbox section but the form showed up blank.

    I haven't been able to get this to work for an iFrame. I have two forms and am trying to grab the submission id of one form and display it on another.

    I added sid={id} to the url of the form and that works, however, it displays as "{id}" in the field.

    Is there a work around that doesn't involve php?

    How do I prepopulate an email input if it doesn't contain a name attribute? All I see available are id, placeholder, size and type. Please help.

  • sandboxlogistics

    One thing I've noticed is if for example I have a full name (i.e.. bla_name[first] and bla_name[last]) that I cannot pull the field values separately when generating the form url on a save submission because the variable name is actually {name} and it has the full name .. therefore a link like ?name[first]={name}&name[last]={name} would pre-populate both fields with the full name... You would think this would work but it doesn't:
