Question

I have a php MySql booking calendar, which shows whether the room is booked or not on a date basis. The problem is, it shows the wrong info. For example, if I book 5-6 it should have marked the 5th red, meaning it was booked on 5th. It shows 6th but by 6, 12:00:00 the room will be free. Another example: If I book 23-25 it shows 24, 25 as booked, but it should show 23-25, dont know where the problem is.

Here is the code:

  function getAllRooms($date,$month,$year)
{
    global $db;
    $where = ' ';
    if ($_GET['room_type'] != '') {
        $where .= " HAVING room_type = '".$_GET['room_type']."'";
    }

    $sql = "SELECT room_type 
            FROM 
                room 
            GROUP BY 
                room_type 
            $where
            ";
    /*echo $sql;
    exit;*/
    $result = $db->Execute($sql);;
    $room = '';
    while (!$result->EOF) {
        $qs     = '?room_type='.$result->fields('room_type').'&month='.$month.'&year='.$year;
        $total  = get_total_rooms_by_type($result->fields('room_type'),$date,$month,$year);
        $room   .=
        '<div class="'.$result->fields('room_type').'"> 

            <a href="'.BASE_URL.'room_detail.php'.$qs.'">
                '.$result->fields('room_type').' ('.$total.')
            </a>
        </div>';
        $result->MoveNext();
    }
    $result->Close;
    return $room;
}
function get_total_rooms_by_type($room_type,$date,$month,$year)
{
    global $db;
    $_newdate   = $year.'-'.$month.'-'.$date;
    $sql            = "SELECT room_id FROM room where room_type = '$room_type' ";
    $room_results   = $db->Execute($sql);
    $room_ids       = array();
    while (!$room_results->EOF) {
        $room_ids[] = $room_results->fields('room_id');
        $room_results->MoveNext();
    }
    $room_results_str = implode(',',$room_ids);
    $where = ' where 1 = 1 ';
    $available = 1;
    if ($_GET['booking_status'] == '1') {
        $where .= ' and (booking_status = 1 or booking_status = 2)';
        $available = 0;
    } else if ($_GET['booking_status'] == '2') {
        $where .= ' and (booking_status = 2)';
        $available = 0;
    } 
    $sql = "select count(room_id) from bookings 
            $where 
                and checkin <= '$_newdate'
                and '$_newdate' <= checkout

Answer 1

it was actually issue of time mismatch. In db I set date time as checkin and checkout but my checking sql retrieving data with date there were no time consideration.

now added:

$_newdate   = $year.'-'.$month.'-'.$date . " " . "12:00:00";

is working like a charm. !!!!
