C4::Log - Koha Log Facility functions

=head1 SYNOPSIS
|
|
|
|
use C4::Log;
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The functions in this module perform various functions in order to log all the operations done on the Database, including deleting and undeleting books, adding/editing members, etc.
|
|
|
|
=head1 FUNCTIONS
|
|
|
|
=over 2
|
|
|
|
=item logaction
|
|
|
|
&logaction($modulename, $actionname, $objectnumber, $infos);
|
|
|
|
Adds a record into action_logs table to report the different changes upon the database.
|
|
Each log entry includes the number of the user currently logged in. For batch
|
|
jobs, which operate without authenticating a user and setting up a session, the user
|
|
number is set to 0, which is the same as the superlibrarian's number.

C<$status> is a hasref like this example:

=item displaylog
|
|
|
|
&displaylog($modulename, @filters);
|
|
$modulename is the name of the module on which the user wants to display logs
|
|
@filters is an optional table of hash containing :
|
|
- name : the name of the variable to filter
|
|
- value : the value of the filter.... May be with * joker
|
|
|
|
returns a table of hash containing who did what on which object at what time
