We can filter on either tags or categories but not on a combination of both.
We would like to filter on both tags and categories. Is there a patch to allow that?
This appears to be the code in class-ailec-events-helper.php, line 841, where the query is created.
// Get the Join (filter_join) and Where (filter_where) statements based on $filter elements specified
$ai1ec_calendar_helper->_get_filter_sql( $filter );
$query = $wpdb->prepare(
"SELECT *, e.post_id, UNIX_TIMESTAMP( e.start ) as start, UNIX_TIMESTAMP( e.end ) as end, e.allday, e.recurrence_rules, e.exception_rules,
e.recurrence_dates, e.exception_dates, e.venue, e.country, e.address, e.city, e.province, e.postal_code,
e.show_map, e.contact_name, e.contact_phone, e.contact_email, e.cost, e.ical_feed_url, e.ical_source_url,
e.ical_organizer, e.ical_contact, e.ical_uid " .
"FROM $wpdb->posts " .
"INNER JOIN {$wpdb->prefix}ai1ec_events AS e ON e.post_id = ID " .
$filter['filter_join'] .
"WHERE post_type = '" . AI1EC_POST_TYPE . "' " .
"AND post_status = 'publish' " .
$filter['filter_where'] .
$start_where_sql .
$end_where_sql,
$args );
I am guessing that the filter is built in class-ailec-calendar-helper.php but I am not sure where.
