<table width="400" border="0">
<td width="18%"><b>year</b> </td>

Let the PHP do this.

If you *must* have a JS solution, I'll show you, but you really, really, should have the PHP page do this combining.

Since Beetle usually doesn't push serverside solutions, he must have a good reason for asking you to let php do it. So, while you look over this, ask him to help with the php solution.

function doit(formObj)
y = formObj.year.options[formObj.year.selectedIndex].value;
m =formObj.month.options[formObj.month.selectedIndex].index;
if (m < 10) m = '0' + m;
d =formObj.day.options[formObj.day.selectedIndex].index;
if (d < 10) d = '0' + d;
formObj.joinedDate.value = y + "/" + m + '/' + d;

<form name='input' action='insert_write.php' method='POST' onsubmit='doit(this)'>

$date = strtotime( $_POST['year'] . "-" . $_POST['month'] . "-" . $_POST['day'] );

Then insert $date into your DB as a timestamp.

I used this exact thing once. Here is the snipet I used to get it to work. It's the same but different (shorter code)

<INPUT type="submit" class="submit" value="insert" onMouseOver="input.joined.value=input.year.value + '/' + input.month.value + '/' + input.day.value">

Just a mouseOver right in the button. The only difference is I made the 'joined' text field a hidden field.:)
