* end date enddate of the search/list, defaults to start + one day
|
|
* users int|array integer user-id or array of user-id's to use, defaults to the current user
|
|
* cat_id int|array category-id or array of cat-id's (incl. all sub-categories), default 0 = all
|
|
* filter string all (not rejected), accepted, unknown, tentative, rejected, hideprivate or everything (incl. rejected, deleted)
|
|
* query string pattern so search for, if unset or empty all matching entries are returned (no search)
|
|
* Please Note: a search never returns repeating events more then once AND does not honor start+end date !!!
|
|
* daywise boolean on True it returns an array with YYYYMMDD strings as keys and an array with events
|
|
* (events spanning multiple days are returned each day again (!)) otherwise it returns one array with
|
|
* the events (default), not honored in a search ==> always returns an array of events!
|
|
* date_format string date-formats: 'ts'=timestamp (default), 'array'=array, or string with format for date
|
|
* offset boolean|int false (default) to return all entries or integer offset to return only a limited result
|
|
* enum_recuring boolean if true or not set (default) or daywise is set, each recurence of a recuring events is returned,
|
|
* otherwise the original recuring event (with the first start- + enddate) is returned
|
|
* num_rows int number of entries to return, default or if 0, max_entries from the prefs
|
|
* order column-names plus optional DESC|ASC separted by comma
|
|
* private_allowed array Array of user IDs that are allowed when clearing private
|
|
* info, defaults to users
|
|
* ignore_acl if set and true no check_perms for a general Acl::READ grants is performed
|
|
* enum_groups boolean if set and true, group-members will be added as participants with status 'G'
|
|
* cols string|array columns to select, if set an iterator will be returned
|
|
* append string to append to the query, eg. GROUP BY
|
|
* cfs array if set, query given custom fields or all for empty array, none are returned, if not set (default)
|
|
* master_only boolean default false, true only take into account participants/status from master (for AS)
|
|
* @param string $sql_filter =null sql to be and'ed into query (fully quoted), default none
|

* @return iterator|array|boolean array of events or array with YYYYMMDD strings / array of events pairs (depending on $daywise param)
|
|
* or false if there are no read-grants from _any_ of the requested users or iterator/recordset if cols are given
