It is primarily used by the 'misc/fines2.pl' script. =head1 FUNCTIONS =head2 Getoverdues $overdues = Getoverdues( { minimumdays => 1, maximumdays => 30 } ); Returns the list of all overdue books, with their itemtype. C<$overdues> is a reference-to-array. Each element is a reference-to-hash whose keys are the fields of the issues table in the Koha database. =cut #' sub Getoverdues { my $params = shift; my $dbh = C4::Context->dbh; my $statement; if ( C4::Context->preference('item-level_itypes') ) { $statement = " SELECT issues.*, items.itype as itemtype, items.homebranch, items.barcode, items.itemlost, items.replacementprice, items.biblionumber, items.holdingbranch FROM issues LEFT JOIN items USING (itemnumber) WHERE date_due < NOW() "; } else { $statement = " SELECT issues.*, biblioitems.itemtype, items.itype, items.homebranch, items.barcode, items.itemlost, replacementprice, items.biblionumber, items.holdingbranch FROM issues LEFT JOIN items USING (itemnumber) LEFT JOIN biblioitems USING (biblioitemnumber) WHERE date_due < NOW() "; } my @bind_parameters; if ( exists $params->{'minimumdays'} and exists $params->{'maximumdays'} ) { $statement .= ' AND TO_DAYS( NOW() )-TO_DAYS( date_due ) BETWEEN ? and ?

The issuingrules table in the Koha database is a fine matrix, listing the penalties for each type of patron for each type of item and each branch (e.g., the standard fine for books might be $0.50, but $1.50 for DVDs, or staff members might get a longer grace period between the first and second reminders that a book is overdue). C<$item> is an item object (hashref). C<$categorycode> is the category code (string) of the patron who currently has the book. C<$branchcode> is the library (string) whose issuingrules govern this transaction. C<$start_date> & C<$end_date> are DateTime objects defining the date range over which to determine the fine. Fines scripts should just supply the date range over which to calculate the fine. C<&CalcFine> returns three values: C<$amount> is the fine owed by the patron (see above). C<$units_minus_grace> is the number of chargeable units minus the grace period C<$chargeable_units> is the number of chargeable units (days between start and end dates, Calendar adjusted where needed, minus any applicable grace period, or hours) FIXME: previously attempted to return C<$message> as a text message, either "First Notice", "Second Notice", or "Final Notice".
