    It is not possible to modify your form's source code then have it uploaded back to our servers. Furthermore, there is no need to edit your source code make URL prepopulation work. You will just have to follow the instructions on the first link given to you by my colleague.

    Here's an example of a prepopulated URL for your form:


    Note how the value I/We request that your investigation reply correspondence be sent to the supplied postal address contains characters that are URL encoded (i.e, %2F, %20). This is to prevent special characters such as the forward slash to be misinterpreted by the browser.

    You may use this URL decoder/encoder to make the value suitable for prepopulation.

    Iam sorry I simply do not understand your instruction, where do i input this stuff you show me a url address where do i type it , where do I edit it, how do I save it, why does the the name heading make a difference, please choose or your decision why would the wording make a difference, why cant a pre pop from the check box edit tool.

    this to me is a failing of the form examples showing pre pop, and non pre pop tells me nothing. A simple line of text showing what it should look like tells me just that but there is no instruction step by step how to achive this

    please explain step by step icon by icon section by section please take the time

    Please accept my apology. The step by step instructions are clearly stated on the link we gave you, hence I did not feel the need to reiterate the same process.


    In any case:

    Preview your form then click Open in new tab

    Right click on the live form then click View Page Source



    Referring to the sample image above, find your checkbox's label (yellow), then copy the name attribute of the input tag under it (in red). Append that value to your form URL, preceded by a question mark and followed by an equals sign:


    Find the value attribute of the input tag (in green), then append it to the modified URL above. If you want to check both options, you will have to separate them with a comma:

    https://www.jotform.com/22352708438354?clickTo[]=Please send complaint on my behalf,I/We request that your investigation reply  correspondence be sent to the supplied postal address

    Notice how this URL does not provide any result, simply because the special character (/) is being misinterpreted by the browser.

    You will have to URL encode the values, one by one to make it work.

    Below is our finished result:


    Note: the option Please send complaint on my behalf is being cleared because it is already set as the checkbox's default value (via the form builder). You will have to remove the default value to make the prepopulation work, or you may leave it as that and remove the option from the URL instead, such as this:


    Hope these instructions as are as clear as can be :)

    following your instruction, i have now found and copied the clickTo[]   how/where do i add this to the url line,

    and if it just a case of adding clickTo[] ?= and the value attribute of the input tag why did we have to go through all the examples, i feel it cant be this simple so what am I missing here, i cant paste anything to the sorce code. so how do i append this

    I understand that this might not quite easy for you but actually this is the simpliest way to pre-populate multiple check boxes, we're sorry about that.

    I have created a short video regarding this (no narration since I'm not totally good on english verbally), I hope this has enlightened you somehow: http://www.screencast.com/t/tSoSdgaz

    For your embed codes, please use iframe embed code and append the URL parameters. Example:


    <iframe allowtransparency="true" src="//form.jotform.me/form/22681118186455?fruits[]=Apple,Orange,Mango&name=JotForm" frameborder="0" style="width:100%; height:457px; border:none;" scrolling="no"></iframe>

    Please be careful on important symbols like ? and &

    Do let us know if you need anything else. Thanks!
