Hi, just wanted to thank you for this extremely powerful tool. The post-processing is my favorite thing to use.

I'm not having any issues with cformsII and have read the FAQs. I just was wondering if there was any way I could make this form show an error message, like the "required" message, letting the user know they MUST check at least one of the checkboxes.

I tried using post-processing to do that, printing a message that says to go back and check at least one document. I just don't want the form to be submitted at all, unless one of those checkboxes is clicked, though.

Does anyone know of a way to do this? I'm not sure if this can be done with a checkbox group?

Thanks in advance!

check box groups can't be required, for that you'd have to use a multi-drop-down box

So this is not possible at all? Not even with some magic in my-functions.php?

anything can be coded, but it'd have to be custom code in the corms core – and I certainly wouldn't consider this a core feature as it would work against the nature of check boxes, which are inherently optional.

just like radio buttons of which one (in a group) is required, with a preselected first button.

a general note: please be aware that cforms is under GPL. now while for 99% of the users this only means: no costs, free source code and a community (or at least the author) maintaining it, it also comes with certain (legal) obligations around code modifications (in a nut shell: make sure to follow the custom code documentation process outlined by GPL).
