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. =cut #' sub logaction { my ($modulename, $actionname, $objectnumber, $infos)=@_; # Get ID of logged in user. if called from a batch job, # no user session exists and C4::Context->userenv() returns # the scalar '0'. my $userenv = C4::Context->userenv(); my $usernumber = (ref($userenv) eq 'HASH') ? $userenv->{'number'} : 0; my $dbh = C4::Context->dbh; my $sth=$dbh->prepare("Insert into action_logs (timestamp,user,module,action,object,info) values (now(),?,?,?,?,?)"); $sth->execute($usernumber,$modulename,$actionname,$objectnumber,$infos); $sth->finish; } =item GetLogStatus $status = GetLogStatus; C<$status> is a hasref like this example: $hash = { BorrowersLog => 1, CataloguingLog => 0, IssueLog => 0, ... } =cut #' sub GetLogStatus { my %hash; $hash{BorrowersLog} = C4::Context->preference("BorrowersLog"); $hash{CataloguingLog} = C4::Context->preference("CataloguingLog"); $hash{IssueLog} = C4::Context->preference("IssueLog"); $hash{ReturnLog} = C4::Context->preference("ReturnLog"); $hash{SubscriptionLog} = C4::Context->preference("SubscriptionLog"); $hash{LetterLog} = C4::Context->preference("LetterLog"); $hash{FinesLog} = C4::Context->preference("FinesLog"); return \%hash; } =item displaylog &displaylog($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....
