我有以下用户输入表格。我需要将mmddyyyy组合成一个变量，然后将其传递给另一个页面以在sql查询中使用。当日期被硬编码时，我可以让查询工作，所以我知道它有效。我没有看到很多关于这个主题的问题，但我相信很多人都必须这样做。
<?
$date=$_POST['date'];
if(isset($date) and $date=="search"){
$month=mysql_real_escape_string($_POST['Month']);
$day=mysql_real_escape_string($_POST['Day']);
$year=mysql_real_escape_string($_POST['Year']);
$reserveStartTime=mysql_real_escape_string($_POST['Time']);
$reserveDate="$month/$day/$year";
echo "mm/dd/yyyy format :$reserveDate<br>";
$reserveDate="$year-$month-$day";
echo "YYYY-mm-dd format :$reserveDate<br>";
echo "$reserveStartTime";
}
?>

It then passes the variable to my sql page..
if (isset($_POST['date']) and $_POST['action']=='Search')
//Get available times for court reservations
try
{
$sql = "SELECT timeslots.courtId, courtName, courtFee, timeslots.slotId, timeslots.reserveStartTime FROM courts INNER JOIN timeslots ON courts.courtId = timeslots.courtId INNER JOIN bookings ON timeslots.slotId != bookings.slotId WHERE bookings.reserveDate = '$reserveDate' AND timeslots.reserveStartTime = '$reserveStartTime'
GROUP BY courtName";
$result = $pdo->query($sql);
}
catch (PDOException $e)
{
$error = 'Error retrieving courts: ' . $e->getMessage();
include 'error.html.php';
include 'error.html.php';
exit();
}
//getting all time slots available
while($row = $result->fetch())
{
$courts[] = array('timeslots.courtId' => $row['courtId'],'courtName' => $row['courtName'],'courtFee' => $row['courtFee'], 'timeslots.slotId' => $row['slotId'], 'reserveStartTime' =>$row['reserveStartTime']);
}
?>
