ByWater Solutions 321eed9833 Bug 4254 - adding new patron advanced notice doesn't save
This was due to poorly constructed SQL which returned duplicate values for
certain fields. This patch corrects that SQL.

NOTE: There is also a formatting problem with the message prefs display table
when it is displayed in moremember.pl. This is due to there being no logic to
tell the table in that context to display checkboxes as appropriate. This patch
does not fix that. Bug 5328 has been opened for this problem.

C4::Members::Messaging - manage patron messaging preferences
=head1 SYNOPSIS
use C4::Members::Messaging
=head1 DESCRIPTION
This module lets you modify a patron's messaging preferences.
=head1 FUNCTIONS
=head2 GetMessagingPreferences
my $preferences = C4::Members::Messaging::GetMessagingPreferences( { borrowernumber => $borrower->{'borrowernumber'},
message_name => 'DUE' } );
my $preferences = C4::Members::Messaging::GetMessagingPreferences( { categorycode => 'LIBRARY',
message_name => 'DUE' } );
returns: a hashref of messaging preferences for a borrower or patron category for a particlar message_name
Requires either a borrowernumber or a categorycode key, but not both.

=head2 SetMessagingPreference
This method defines how a user (or a default for a patron category) wants to get a certain
message delivered. The list of valid message types can be delivered can be found in the
C<message_attributes> table, and the list of valid message transports can be
found in the C<message_transport_types> table.

message_attribute_id => $message_attribute_id,
message_transport_types => [ qw( email sms ) ],
