HTML form date mm/dd/yy to MySQL date

[jay_suz]

how do you convert the 3 values to one string (and can anyone do it is asp)

i have 3 drop down boxes, day mont year, need one string value to write to mysql.

i can do the format from mm/dd/yy to MySQL date. just dont know how to make the 3 values to 1

[stew]

$day = $_POST["day"];
$month = $_POST["month"];
$year = $_POST["year"];

$date = $year .'-'. $month .'-'. $day;

The $date should be in the form yyyy-mm-dd, i think!
