Question

Just after a check to make sure one hidden field is not empty.

if($('#cal_startdate').val('')) {
        alert('Please select a start date') }
        else { form.submit }

That isn’t quite right. I’d rather it was an onsubmit action.

Any ideas,

Marvellous

You’ll want to attach the validation to the submit() event handler. If data is valid, return true – else, return false.

$('form').submit(function(){
    if ($('#cal_startdate').val().length==0){
        alert('Please Enter Start Date');
        return(false);
    }
    return(true);
});
