C4::Accounts - Functions for dealing with Koha accounts

=head1 SYNOPSIS
|
|
|
|
use C4::Accounts;
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The functions in this module deal with the monetary aspect of Koha,
|
|
including looking up and modifying the amount of money owed by a
|
|
patron.

&recordpayment($borrowernumber, $payment);
|
|
|
|
Record payment by a patron. C<$borrowernumber> is the patron's
|
|
borrower number. C<$payment> is a floating-point number, giving the
|
|
amount that was paid.
|
|
|
|
Amounts owed are paid off oldest first. That is, if the patron has a
|
|
$1 fine from Feb. 1, another $1 fine from Mar. 1, and makes a payment
|
|
of $1.50, then the oldest fine will be paid off in full, and $0.50
|
|
will be credited to the next one.

Records the fact that a patron has paid off the entire amount he or

|
she owes.
|
|
|
|
C<$borrowernumber> is the patron's borrower number. C<$acctnumber> is
|
|
the account that was credited. C<$amount> is the amount paid (this is
|
|
only used to record the payment. It is assumed to be equal to the
|
|
amount owed). C<$branchcode> is the code of the branch where payment
|
|
was made.
