=head1 NAME

C4::Form::MessagingPreferences - manage messaging prefernces form

=head1 SYNOPSIS

In script:

    use C4::Form::MessagingPreferences;
    C4::Form::MessagingPreferences::set_form_value({ borrowernumber => 51 }, $template);
    C4::Form::MessagingPreferences::handle_form_action($input, { categorycode => 'CPL' }, $template);

In HTML template:

    <!-- TMPL_INCLUDE NAME="messaging-preference-form.inc" -->

=head1 DESCRIPTION

This module manages input and output for the messaging preferences form
that is used in the staff patron editor, the staff patron category editor,
and the OPAC patron messaging prefereneces form.  It in its current form,
it essentially serves only to eliminate copy-and-paste code, but suggests
at least one approach for reconciling functionality that does mostly
the same thing in staff and OPAC.

=head1 FUNCTIONS

=head2 handle_form_action

    C4::Form::MessagingPreferences::handle_form_action($input, { categorycode => 'CPL' }, $template, $insert);

Processes CGI parameters and updates the target patron or patron category's
preferences.

C<$input> is the CGI query object.

C<$target_params> is a hashref containing either a C<categorycode> key or a C<borrowernumber> key 
identifying the patron or patron category whose messaging preferences are to be updated.

C<$template> is the Template::Toolkit object for the response; this routine
adds a settings_updated template variable.

=head2 set_form_values

    C4::Form::MessagingPreferences::set_form_value({ borrowernumber => 51 }, $template);

Retrieves the messaging preferences for the specified patron or patron category
and fills the corresponding template variables.

C<$target_params> is a hashref containing either a C<categorycode> key or a C<borrowernumber> key 
identifying the patron or patron category.

C<$template> is the Template::Toolkit object for the response.
