quickform - checking a valid date rule for a date element

Hi, I am using Quickform to display a date, and I want to check that the date selected by the user is a valid-date, using checkdate() . I have a date element, weddingdate: $form->addElement('date', 'weddingdate', 'Wedding Date: ', array('minYear'=>2005, 'maxYear'=>2015)); I made a custom rule - by making a function, then registering the rule: function qfdate($somedate) { if ($somedate['d'] != '' && $somedate['M'] != '' && $somedate['Y'] != '') { return checkdate($somedate['M'], $somedate['d'], $somedate['Y']); //nb order! } return false; // its not valid } $form->registerRule('isadate', 'function', 'qfdate'); then attaching the Rule to the date element: $form->addRule('weddingdate','Please enter a valid date', 'isadate'); // GroupRule or not? But it doesnt work - I have tried with a GroupRule and that didnt work either. When I output the parameter being passed to my function qfdate during the validation, it is a empty string. If it is done with the group rule the function is called 3 times as opposed to once for the normal rule. Any help or pointers appreciated! thanks Luke -- ~L~ lukebarker@gmail.com http://www.battez.org --------------------------------------- I'm doggone gonna be with Some real people... ( R & E )
