Booking calendar on the bookable resource page

thanks tirsales,
i used calendar_block module for this, this module has hook where i can write some code to display available days for the flat.
It's very cool module.

sure, this is a hook_calendar_block, i used it in the publicbookings.module.

function publicbookings_calendar_block(&$calendar, &$date, $op) {
switch($op) {
case 'alter':
$sql = "SELECT start, end
FROM bookings_schedules
WHERE resource_id = '%s' AND status = '4'";
$q = db_query($sql, $calendar->resource_id);
while ($row = db_fetch_array($q))
{
$start_date = strtotime($row['start']);
$end_date = strtotime($row['end']);
$cur_date = strtotime($date->day.".".$date->month.".".$date->year);
if($start_date <= $cur_date && $end_date >= $cur_date)
{
$date->content = '

';
}
}
$sql = "SELECT start, end
FROM bookings_schedules
WHERE resource_id = '%s' AND status = '2'";
$q = db_query($sql, $calendar->resource_id);
while ($row = db_fetch_array($q))
{
$start_date = strtotime($row['start']);
$end_date = strtotime($row['end']);
$cur_date = strtotime($date->day.".".$date->month.".".$date->year);
if($start_date <= $cur_date && $end_date >= $cur_date)
{
$date->content = '

';
}
}
break;
}
}

there i mark calendar of unconfirmed and booked days for the flat.

then, i change some code of calendar_block.module
I was change $calendar object on line 126, i add resource_id param:

// Resource ID used for Booking system
$resource_id = 0;
if (arg(0) == 'node') $resource_id = arg(1);
$calendar = (object) array(
'year' => date('Y'),
'month' => date('m'),
'weekdays' => $weekdays,
'resource_id' => (int)$resource_id,
);

And then i change calendar_block.js file, on line 63 i add this:
ref.ajax_settings.data.resource_id = Drupal.toJson(ref.settings.calendar.resource_id);

Then i put calendar_block block into my page.
That's all.
