42 C4::Stats - Update Koha statistics (log)
50 The functions of this module deals with statistics table of Koha database.
56 &UpdateStats($params);
58 Adds an entry to the statistics table in the Koha database, which acts as an activity log.
60 C<$params> is an hashref whose expected keys are:
61 branch : the branch where the transaction occurred
62 type : the type of transaction (renew, issue, localuse, return, writeoff, payment
63 itemnumber : the itemnumber of the item
64 borrowernumber : the borrowernumber of the patron
65 amount : the amount of the transaction
67 itemtype : the type of the item
69 ccode : the collection code of the item
71 type key is mandatory.
72 For types used in C4::Circulation (renew,issue,localuse,return), the following other keys are mandatory:
73 branch, borrowernumber, itemnumber, ccode, itemtype
74 For types used in C4::Accounts (writeoff, payment), the following other keys are mandatory:
75 branch, borrowernumber, itemnumber, ccode, itemtype
76 If an optional key is not provided, the value '' is used for this key.
