Is it possible to trigger a webform submit via url? I have set up a webform for simple user polling with an yes/no option, with a submit button.

  [ ] Yes
  [ ] No

  Submit


and the parameter is pass via URL as default, e.g.:

 http://example.com/event_form?option=y


Currently, the webform link is sent via email. So users click the link, open a browser, select an option or use the default, press submit, and see the confirmation message.

Is it possible to automate the submit click? Such that the submit button is automatically clicked after clicking on the link in email?
Inject some javascript into the body using PHP can make auto submit to work by a param in URL:

 http://example.com/event_form?autosubmit=yes&amp;option=y


For example, the webform node ID is 101:

&lt;?php if ($_REQUEST['autosubmit']) { ?&gt;

    &lt;script&gt;
    (function ($) {     
        $(document).ready(function(){
            $('form#webform-client-form-101').submit();
        });
    })(jQuery);
    &lt;/script&gt;

&lt;? } ?&gt;
