You can use NOW() in your MySQL query which will store the current date and time.

thanks for reply. i used NOW() in query but i getting same datetame in login and logout column.
this is radio button code:

<input type="radio" name="login"  >LogIn
<input type="radio" name="logout">LogOut

and

<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
$data_base="log";
mysql_select_db($data_base, $con);
if($_SERVER['REQUEST_METHOD']=="POST"){
$name = $_POST['name'];
$empid = $_POST['empid'];
$shift = $_POST['shift'];
$login = $_POST['login'];
$logout = $_POST['logout'];

$login = 'unchecked';
$logout = 'unchecked';

if (isset($_POST['Submit'])) {

$selected_radio = $_POST['log'];

if ($selected_radio == 'login') {

$login = 'checked';

}
else if ($selected_radio == 'logout') {

$logout = 'checked';

}}

$sql="INSERT INTO emp (name,empid,shift,login,logout)VALUES ('$name','$empid','$shift',now(),now())";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
}

echo "Your Information Was Successfully Posted";
include('thankyou.php');
mysql_close($con);
?>

ple help me.

You should only update the login column when logging in, and the logout column when logging out, not both at the same time.
