When creating an unchecked box, create a hidden element with a name/value pair that describes it. The hidden element will be submitted.

In this case case the server has no way of knowing that the checkbox was on the form because the browser doesn't include the checkbox in the request if it's not checked. In this particular application, provision is made for end users to create their own data capture forms, place them on the server and either email the submissions to central command or write them to a text file. The web application uses the key/value pairs to list the data either in the email body, e.g.: frm_surname: Pike frm_firstname: Magnus etc. Where checkboxes are concerned they would like to see: frm_requestmailing: No . . . instead this line omitted because the browser simply doesn't sent any value for an unchecked checkbox and the server doesn't know the form structure so it can't 'inject' the key/value pair itself. One workaround is to use 'yes-no' radio buttons, but the customer would prefer checkboxes simply because their customers do. Any tips on dealing with this would be appreciated.
