Passing checkbox value to url using powerform docusign

Question

Can you guys help me how to pass a value for checkbox input field to the url using powerform docusign, it seems like the docusign does not recognize my settings. I can only pass the value of radio input field.

$parameter = "&checkbox_field=1&radio_field=1"

where value 1 stands for 'selected' and it working on radio input field, and not working on checkbox. Sorry for my english.

Answer 1

I have found solution to it, just replace value 1 to 'x'.

$parameter = "&checkbox_field=x&radio_field=x";
