Yes using the example exactly as provided COULD cause the form to be 
filled with false.  Most likely php will treat the boolean false as a 
null string so the boxes would be empty.  To guarantee this mod the code 
to say this :

$aDate = isset($_POST['postdate']) ? $_POST['postdate'] : "";

Now if the variable is not set $aDate is given a value of empty string so nothing would be written to your text boxes.
