thank you,

but i couldnt find the group name of date element.

i tried this line;
$form1->addGroupRule("dc_date","Date", 'required', "null", 3);

it doesnt work..

The group name is the element name of the date element, i.e. 'dc_date' is right. But are you sure about $form1? In your first post it was $form. And 'null' is wrong, it needs to be simply null, without the quotes (it is a PHP constant).

yes sorry,

my form name is form1.
both of my date element and addgrouprule form is same.
and i also tried NULL without quotes.. but it doesnt work..

i use html_quickform with PHP5, should i use html_quickform2?
is it important? i see it today and i dont even know its usage..

you are right,

a true addEmptyOption gaves me 0000-00-00 if user was not select value. if i set false, date returns 1900-00-00 as an empty value.. i dont want this situation..

anyway..thanks
