Question

All,
I have the following code:

$fetch = mysql_query("SELECT * FROM calendar_events where event_status='booked' and event_type='wedding' GROUP BY start"); 
while ($row = mysql_fetch_array($fetch, MYSQL_ASSOC)) {
    $row_array['id'] = $row['id'];
    $row_array['title'] = $row['title'];
    $row_array['start'] = $row['start'];
    $row_array['end'] = $row['end'];
    array_push($return_arr,$row_array);
}
echo json_encode($return_arr);

I’m using the fullcalendar and trying to determine how many events have the same start date. So for example if I had the following dates:

02/06/2012
02/06/2012
03/01/2012
04/05/2012

On dates that have entries in my database I’d like to basically see how many events are on that date and basically say how many spots are left. So for any given date I can have two scheduled events so for 02/06/2012 I’d like it to return “Booked” and for 03/01/2012 I’d like “1 spot left” and etc.

How can I go about doing something like this?

Thanks!

SELECT 
start, count(*) as used, 2-count(*) as free
FROM calendar_events 
WHERE event_status='booked' 
  and event_type='wedding'
GROUP BY start

or as by your comment:

SELECT 
date(start) as eventdate, count(*) as used, 2-count(*) as free
FROM calendar_events 
WHERE event_status='booked' 
  and event_type='wedding'
GROUP BY date(start)
