Step1. Database creation
  • Open PHPMyAdmin using http://localhost/phpmyadmin in XAMPP 
  • Create Database: HOTEL 
  • Create Table:
    • CREATE TABLE IF NOT EXISTS `rooms_info` (
  `booking_id` int(11) NOT NULL AUTO_INCREMENT,
  `room_no` varchar(55) NOT NULL,
  `check_in` date NOT NULL,
  `check_out` date NOT NULL,
  `no_of_rooms` int(11) NOT NULL,
  PRIMARY KEY (`booking_id`),
  KEY `room_no` (`room_no`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=10;
  • Insert some dummy data for a start
    • INSERT INTO `rooms_info` (`booking_id`, `room_no`, `check_in`, `check_out`, `no_of_rooms`) VALUES
(1, '1', '2013-01-02', '2013-01-03', 3),
(2, '2', '2013-01-03', '2013-01-04', 3),
(3, '3', '2013-01-01', '2013-01-04', 2),
(4, '4,5', '2013-01-04', '2013-01-05', 2),
(5, '2,3,4', '2013-01-05', '2013-01-25', 2),
(6, '5,6,8', '2013-02-07', '2013-02-28', 3),
(7, '4,5,6', '2013-10-05', '2013-11-09', 3),
(8, '2,3,4', '2013-03-05', '2013-03-08', 3),
(9, '5,6,7', '2013-01-05', '2013-01-08', 3);
Step2. User Interface

Create index.php file where user can submit reservation form as well as gets update about reservation status
index.php
<?php
include('config.php');
if (isset($_GET['submit'])) {
    /* Getting data from form submitted at index.php page */
    $user_checkin_date = $_GET['checkin_date'];
    $user_checkin_month = $_GET['checkin_month'];
    $user_checkin_year = $_GET['checkin_year'];
    $user_checkout_date = $_GET['checkout_date'];
    $user_checkout_month = $_GET['checkout_month'];
    $user_checkout_year = $_GET['checkout_year'];
    $persons = $_GET['persons']; // this variable will be used when we scale up this application
    $rooms = $_GET['rooms'];
    /* End of collecting data */

//Check for any invalid submissions, you should apply as much validation as possible
    if ($user_checkin_month == 2 || $user_checkin_month == 4 || $user_checkin_month == 6 || $user_checkin_month == 9 || $user_checkin_month == 11 || $user_checkout_month == 2 || $user_checkout_month == 4 || $user_checkout_month == 6 || $user_checkout_month == 9 || $user_checkout_month == 11) {
        if ($user_checkin_date >= 31 || $user_checkout_date >= 31) {
            $error = 1;
            $error_type[] = "For month $user_checkin_month 31st is invalid Date";
        } else if ($user_checkin_month == 2 || $user_checkout_month == 2) {
            if ($user_checkin_date >= 28 || $user_checkout_date >= 28) {
                $error = 1;
                $error_type[] = 'Feb Date Error';
            }
        } else {
            $error = 0;
        }
    } else {
        $error = 0;
    }
    if ($user_checkin_date >= $user_checkout_date) {

        $error = 1;
        $error_type[] = "Check out date can't be equal or lesser than check in date , please try again!!";
    }

// converting date into yyyy-mm-dd format
    $user_checkin_date = "$user_checkin_year" . "-" . "$user_checkin_month" . "-" . "$user_checkin_date";
    $user_checkout_date = "$user_checkout_year" . "-" . "$user_checkout_month" . "-" . "$user_checkout_date";
// info convert into unix timestamp
    $user_checkin_date = strtotime($user_checkin_date);
    $user_checkout_date = strtotime($user_checkout_date);
    global $total_rooms_available;
    $total_rooms_available = 10;
    while ($row = mysql_fetch_array($result)) {
        $check_in = $row['check_in'];
        $check_out = $row['check_out'];
        $no_of_rooms = $row['no_of_rooms'];
        $check_in = strtotime($check_in);
        $check_out = strtotime($check_out);
// test for availability with check in and check out date
        if ($check_in <= $user_checkin_date && $user_checkin_date < $check_out) {

            $room_available = 0;
            $total_rooms_available = $total_rooms_available - $no_of_rooms;
        } // end of if check in loop
        else {
            if ($check_in < $user_checkout_date && $user_checkout_date <= $check_out) {
                $room_available = 0;
                $total_rooms_available = $total_rooms_available - $no_of_rooms;
            } // end of if checkout loop
            else {
                $room_available = 1;
            } // end of else check out loop
        }
    }
}// end of if submit button has pressed  
?>

?>

 Step3. Admin Section 
In admin section, we will need mainly three files and one class, first admin/index.php and second admin/login_success.php third admin/Logout.php and fourth one is third party class tc_calendar(optional) which helps us to show javascript calendar.

  • Create new folder Admin
  • Create index file and paste php source shown below
    • // user name and password for admin, preferred way is to create database user table inside database
$username = "hotel";
$password = "123456";
if (isset($_POST['Submit'])) {
// username and password sent from form 
    $myusername = $_POST['myusername'];
    $mypassword = $_POST['mypassword'];

// To protect MySQL injection 
    $myusername = stripslashes($myusername);
    $mypassword = stripslashes($mypassword);
    $myusername = mysql_real_escape_string($myusername);
    $mypassword = mysql_real_escape_string($mypassword);
} // end of isset post submit
?>
