PHP Date Picker

I have a date field which is intended for the user to enter. From my experience, users typically make errors in the format (dd/mm/yyyy & mm/dd/yyyy). Therefore, instead of having users to key in the dates, I intend to have a date picker, much a the calendar function.

I intend to have the date field grey and disabled for data entry, a little icon beside the field where upon clicking, a popup calendar appears adn user simply click on the desired date.

Can anyone point me in the right direction? Appreciate your assistance.

 

This is javascript thing. www DOT corion DOT net/js/datepicker/index.html (post count thingy)

 

Another way round it is to have selection boxes

<form method = "POST" action="page.php">
<select name="date_d"><option>01</option>02......</select>
<select name"date_m"><option value="01">January</option><option value="02">Febuary............</select>
<select name="date_y"><option>2005</<option><option>2006..........</select>
</form>
then

$date_d = $_POST["date_d"];
$date_m = $_POST["date_m"];
$date_y = $_POST["date_y"];
$date = ($date_y-$date_m-$date_d);

echo $date;
////Just to check it is done correctly

This becomes a pain for DOB, as where do you start 1900 to 2000, thats 100 options to choose from
