=head1 NAME

C4::Members - Perl Module containing convenience functions for member handling

=head1 SYNOPSIS

use C4::Members;

=head1 DESCRIPTION

This module contains routines for adding, modifying and deleting members/patrons/borrowers 

=head1 FUNCTIONS

=over 2

=item SearchMember

  ($count, $borrowers) = &SearchMember($searchstring, $type,$category_type,$filter,$showallbranches);

Looks up patrons (borrowers) by name.

BUGFIX 499: C<$type> is now used to determine type of search.
if $type is "simple", search is performed on the first letter of the
surname only.

$category_type is used to get a specified type of user. 
(mainly adults when creating a child.)

C<$searchstring> is a space-separated list of search terms. Each term
must match the beginning a borrower's surname, first name, or other
name.

C<$filter> is assumed to be a list of elements to filter results on

C<$showallbranches> is used in IndependantBranches Context to display all branches results.

C<&SearchMember> returns a two-element list. C<$borrowers> is a
reference-to-array; each element is a reference-to-hash, whose keys
are the fields of the C<borrowers> table in the Koha database.
C<$count> is the number of elements in C<$borrowers>.

=head2 GetMemberDetails

($borrower, $flags) = &GetMemberDetails($borrowernumber, $cardnumber);

Looks up a patron and returns information about him or her. If
C<$borrowernumber> is true (nonzero), C<&GetMemberDetails> looks
up the borrower by number; otherwise, it looks up the borrower by card
number.

C<$borrower> is a reference-to-hash whose keys are the fields of the
borrowers table in the Koha database. In addition,
C<$borrower-E<gt>{flags}> is a hash giving more detailed information
about the patron. Its keys act as flags :

    if $borrower->{flags}->{LOST} {
        # Patron's card was reported lost
    }

Each flag has a C<message> key, giving a human-readable explanation of
the flag. If the state of a flag means that the patron should not be
allowed to borrow any more books, then it will have a C<noissues> key
with a true value.

The possible flags are:

=head3 CHARGES

=over 4

=item Shows the patron's credit or debt, if any.

=back

=head3 GNA

=over 4

=item (Gone, no address.) Set if the patron has left without giving a
forwarding address.

=back

=head3 LOST

=over 4

=item Set if the patron's card has been reported as lost.

=back

=head3 DBARRED

=over 4

=item Set if the patron has been debarred.

=back

=head3 NOTES

=over 4

=item Any additional notes about the patron.

=back

=head3 ODUES

=over 4

=item Set if the patron has overdue items. This flag has several keys:

C<$flags-E<gt>{ODUES}{itemlist}> is a reference-to-array listing the
overdue items. Its elements are references-to-hash, each describing an
overdue item. The keys are selected fields from the issues, biblio,
biblioitems, and items tables of the Koha database.

C<$flags-E<gt>{ODUES}{itemlist}> is a string giving a text listing of
the overdue items, one per line.

=back

=head3 WAITING

=over 4

=item Set if any items that the patron has reserved are available.

C<$flags-E<gt>{WAITING}{itemlist}> is a reference-to-array listing the
available items. Each element is a reference-to-hash whose keys are
fields from the reserves table of the Koha database.
