Maybe you should do the following. At the point where the switch
"date" or "NULL" in the php-file is:
if(empty($form_date)){
$date_var = NULL;
}else $date_var = "'$date'";
$query = "INSERT INTO table (table_row1, date)
VALUES ('$value1', $date_var);";
You still have the if/else, but I think there must be somewhere the
switch NULL <=> date
