Cannot enable booking with $EM_Event save

try try codes under classes/em_tickets.php and classes/em_ticket.php function save()

Thanks angelo i’ve managed to do what i wanted: enable booking programmatically during the event creation.
The trick was to create a new ticket in the db using the $EM_Ticket object

Here is my code :

$EM_Event = new EM_Event();

/*
// time strings for test
$EM_Event->event_start_date = "2016-01-26";
$EM_Event->event_end_date = "2016-01-26";
$EM_Event->event_start_time = "16:30:00";
$EM_Event->event_end_time = "18:30:00";
*/

$cur_time = current_time( 'timestamp', 1 );
$timestamp_start = strftime("%Y-%m-%d %H:%M:%S", $cur_time + 720*60*60); // 720 hours = + 30 days
$timestamp = strftime("%Y-%m-%d %H:%M:%S", $cur_time + 744*60*60); // 720 hours = + 30 days

//$date_start_default = date( 'Y-m-d', current_time( 'timestamp', 1 ) );
$date_start_default = date( 'Y-m-d', strtotime($timestamp_start) ); // time + 1 year to enable booking
$date_end_default = date( 'Y-m-d', strtotime($timestamp) );
$date_time_default = date( 'H:i:s', strtotime($timestamp_start) );
//$date_time_default = date( 'H:i:s', current_time( 'timestamp', 1 ) );

$EM_Event->event_start_date = $date_start_default;
$EM_Event->event_end_date = $date_end_default;

$EM_Event->event_start_time = $date_time_default;
$EM_Event->event_end_time = $date_time_default;

$EM_Event->start = strtotime($EM_Event->event_start_date." ".$EM_Event->event_start_time);
$EM_Event->end = strtotime($EM_Event->event_end_date." ".$EM_Event->event_end_time);

$EM_Event->event_private = 0;
$EM_Event->event_status = 1;
$EM_Event->event_rsvp = 1;
$EM_Event->event_rsvp_date = $date_end_default;
$EM_Event->rsvp_end = $date_end_default;
$EM_Event->event_rsvp_time = $date_time_default;
$EM_Event->event_rsvp_spaces = 0;
$EM_Event->event_spaces = 10000;
$EM_Event->event_all_day = 0;

$EM_Event->event_owner = $user_id;

// attach the event to a buddypress group
// we presume you've got the related group_id
$EM_Event->group_id = $group_id;   

$EM_Event->post_content = $post_content;
$EM_Event->post_excerpt = '';
$EM_Event->event_slug = $post_slug;
$EM_Event->event_name = $post_title;

// we could save booking information on event creation
// for eg. If we want the event creator to have automaticaly his booking recorded

// create the event post to link with the bp group

$EM_Event->save();
$EM_Event->save_meta();

/*
// we need now to save a new ticket for this event to enable booking
// in db table 'wp_em_tickets'
// see function 'save' in classes/em-ticket.php
* ===================================================================
*/

// we need to catch back the event id
$current_event = em_get_event($EM_Event->ID,'post_id');
$current_event_id = $current_event->event_id;

$EM_Ticket = new EM_Ticket();
$EM_Ticket->event_id = $current_event_id;
$EM_Ticket->ticket_name = $EM_Event->event_name;
$EM_Ticket->ticket_end = $EM_Event->rsvp_date;

if ($current_event && $EM_Event->event_rsvp == 1) {
$EM_Ticket->save();
}

Thanks for your support
Hope that helps someone else ??
