36 C4::Log - Koha Log Facility functions
44 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.
53 @EXPORT = qw(&logaction &logstatus &displaylog);
57 &logaction($usernumber, $modulename, $actionname, $infos);
59 Adds a record into action_logs table to report the different changes upon the database
64 my ($usernumber,$modulename, $actionname, $objectnumber, $infos)=@_;
65 $usernumber='' unless $usernumber;
66 my $dbh = C4::Context->dbh;
67 my $sth=$dbh->prepare("Insert into action_logs (timestamp,user,module,action,object,info) values (now(),?,?,?,?,?)");
68 $sth->execute($usernumber,$modulename,$actionname,$objectnumber,$infos);
76 returns True If Activate_Log variable is equal to On
77 Activate_Log is a system preference Variable
81 return C4::Context->preference("Activate_Log");
86 &displaylog($modulename, @filters);
87 $modulename is the name of the module on which the user wants to display logs
88 @filters is an optional table of hash containing :
89 - name : the name of the variable to filter
90 - value : the value of the filter.... May be with * joker
92 returns a table of hash containing who did what on which object at what time
