How to control date

[new_php85]

i...i have some problem to control entry date.i want, user cannot add claim when the "date_me" have over limit which the date is not valid anymore. for example date_me only can accept date in october but after october the date is not valid.currently i only use like this.but i think there is some better code.

 

this is is my example coding

 

<?php session_start();
include 'includes/db_connect.php';
include 'includes/css.php';

if (isset($_POST['bttnAdd']))
{
$me_id = $_POST['me_id'];
$staff_id = $_POST['staff_id'];
$date_me = $_POST['date_me'];
$particular = $_POST['particular'];
$bill_me = $_POST['bill_me'];
$ammount_me = $_POST['ammount_me'];

$data = 1;
$query = "INSERT INTO me(staff_id, date_me, particular, bill_me, ammount_me)
		  VALUES('$staff_id','$date_me','$particular','$bill_me','$ammount_me') WHERE date_me != '2008-10-28'";
mysql_query($query) or die('Query failed. ' . mysql_error());

echo "<script language='JavaScript'> alert('The record is successfully added');</script>";
echo "<script language='JavaScript'> window.location ='me.php';</script>";
}
?>

<form name="me" action='me.php' method = "post" onSubmit="return validateForm(this,arrFormValidation);">
<table width="678" align="center">
<tr> 
    	<td height="20" colspan="2" class="tajukkecil"><b>Miscellaneous Expense</b></td>
