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.
