Try this code in your
Try this code in your form:
CODE
<script type="text/javascript">
function validateForm(){
var process = "yes"
var dateFilter = /^\d{1,2}(\-|\/|\.)\d{1,2}\1\d{4}$/;
if(document.yourForm.myDate.value == "" || !dateFilter.test(document.yourForm.myDate.value)){
alert('The date you entered is invalid');
process = "no"
} // end of if
if(process == "yes"){
document.yourForm.submit();
} // end of if
} // end of function validateForm
</script>
<form name="yourForm" method="yourMethod" action="yourAction">
Your form content

what does the \1 do?does that
what does the \1 do?
does that tell it to repeat the first group? eg. -> (\-|\/|\.) ?

That actually wasn't the best
That actually wasn't the best way to write that expression. Upon looking back at it, I'm not sure why I did it that way. It will work, but to make things a little less confusing, use the following expression:
(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)\d\d
This one might not be as complicated.

I should never post during
I should never post during prime time... that last expression wouldn't work well with the javascript... you should still use /^\d{1,2}(\-|\/|\.)\d{1,2}\1\d{4}$/. The other one would be used better in php or perl.
Sorry. My Bad.

the original regex i wrote
the original regex i wrote was for js, not php....
and it should work just fine matching a full sql date

That's supposed to be
That's supposed to be YYYY-MM-DD, right?
CODE
<?php
$date = '2005-03-09';
if (!preg_match('/^[0-9]{4}-[0-9]{2}-[0-9]{2}$/', $date))
{
echo 'Please enter a date in the format: YYYY-MM-DD.';
}
?>

D'ya want another one.
D'ya want another one. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
CODE
^[0-9]{4}-(((0[13578]|(10|12))-
(0[1-9]|[1-2][0-9]|3[0-1]))|
(02-(0[1-9]|[1-2][0-9]))|
((0[469]|11)-(0[1-9]|[1-2][0-9]|30)))$
(0[1-9]|[1-2][0-9]|3[0-1]))|
(02-(0[1-9]|[1-2][0-9]))|
((0[469]|11)-(0[1-9]|[1-2][0-9]|30)))$
(Should all be one line) Matches the date format "YYYY-mm-dd" and also validates month and number of days in a month. All leap year dates "YYYY-02-29" passes trough. Could easily be changed to another format.
