Parameters
- $guid : string
-
The name of the history entry to retrieve.
- $use_ts : bool = false
-
If false we use the 'modseq' field to determine the latest entry. If true we use the timestamp instead of modseq to determine the latest entry. Note: Only 'modseq' can give a definitive answer.
Tags
Return values
array<string|int, mixed>|bool —The latest history entry, or false if $guid does not exist.
log()
Logs an event to an item's history log.
public
log(string $guid[, array<string|int, mixed> $attributes = array() ][, bool $replaceAction = false ]) : mixed
The item must be uniquely identified by $guid. Any other details about the event are passed in $attributes. Standard suggested attributes are:

Parameters
- $guid : string
-
The unique identifier of the entry to add to.
- $attributes : array<string|int, mixed> = array()
-
The hash of name => value entries that describe this event.
- $replaceAction : bool = false
-
If $attributes['action'] is already present in the item's history log, update that entry instead of creating a new one.
