Php/mysql check number of booked rooms

Question

I'm having a small issue regarding on how to check if a room is booked or not.

So basically I a have a table as shown below

Accomm

1. accomm_id
2. checkin [stored as timestamp]
3. checkout [stored as timestamp]

What I have so far, is that if the user inputs a checkin and checkout date which are both converted to timestamps. That part is done.

So what i have failed to figure out is the following:

• Search the accomm table for using the checkin and checkout paramters that the user entered.
• Then return the number of booked rooms.

Please assist or guide me on this one. Thanks.

$booked_rooms = 0;
while($accommodation_package = mysql_fetch_array($query)) {

    // $this->checkin, $this->checkout are values fed by the user
    // $accommodation_package['checkin/out'] are the values in the database
    if($this->checkin >= $accommodation_package['checkin'] && $this->checkout <= $accommodation_package['checkout']) {
        $booked_rooms +=1;
    }
}
echo $booked_rooms;

Well I thought the above would work but when checkin and checkout dates from the client are on different months it does not work.

Answer 1

Assuming that you have stored our check-in and check-out dates in the format 'dmY' >ou could execute the following SQL statement:

SELECT COUNT(acomm_id) FROM Accomm WHERE checkin <= yourDateString AND checkout => yourDateString

Hope this helps.

Answer 2

Try with this:

<?php
$currentTime = date('Y-m-d H:i:s');

$sql = "SELECT COUNT(accomm_id)
        FROM accom
        WHERE checkin <= $currentTime
        AND checkout >= $currentTime";
$query = mysqli_query($sql);
// code to get the details.
