How to add a addGroupRule for group of checkbox ?
 

Hi

This is my code,

$checkboxarr = array();


$checkboxarr[]=$mform->createElement('checkbox','c','',);

$checkboxarr[]=$mform->createElement('checkbox','cpp','',);

$checkboxarr[]=$mform->createElement('checkbox','java','',);


$mform->addGroup($checkboxarr,'lang','Choose the language',array(''),false);

$mform->addGroupRule('lang', $checkboxarr,null,null,'client');


I used addGroupRule but it didn't work out.

Now I need to do the validation, at least any one of the checkboxes should be checked.

I searched in the forum, I didn't get any solution.

Help me with this. Correct me if I am doing anything wrong.

Thanks in Regards.
