=head1 NAME
C4::Letters - Give functions for Letters management
=head1 SYNOPSIS
use C4::Letters;
=head1 DESCRIPTION
"Letters" is the tool used in Koha to manage informations sent to the patrons and/or the library. This include some cron jobs like
late issues, as well as other tasks like sending a mail to users that have subscribed to a "serial issue alert" (= being warned every time a new issue has arrived at the library)
Letters are managed through "alerts" sent by Koha on some events. All "alert" related functions are in this module too.
=head2 GetLetters([$category])
$letters = &GetLetters($category);
returns informations about letters.
if needed, $category filters for letters given category
Create a letter selector with the following code
=head3 in PERL SCRIPT
my $letters = GetLetters($cat);
my @letterloop;
foreach my $thisletter (keys %$letters) {
my $selected = 1 if $thisletter eq $letter;
my %row =(
value => $thisletter,
selected => $selected,
lettername => $letters->{$thisletter},
);
push @letterloop, \%row;
}
$template->param(LETTERLOOP => \@letterloop);
=head3 in TEMPLATE
<select name="letter">
<option value="">Default</option>
<!-- TMPL_LOOP name="LETTERLOOP" -->
<option value="<!-- TMPL_VAR name="value" -->" <!-- TMPL_IF name="selected" -->selected<!-- /TMPL_IF -->><!-- TMPL_VAR name="lettername" --></option>

letter - the standard letter hashref
