=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.
=cut
=head2 GetLetters
$letters = &getletters($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;
}
=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>

create an alert and return the alertid (primary key)

- $type : the type of alert.
- externalid : the primary key of the object to put alert on. For issues, the alert is made on subscriptionid.
all parameters NON mandatory. If a parameter is omitted, the query is done without the corresponding parameter. For example, without $externalid, returns all alerts for a borrower on a topic.

=head2 findrelatedto
parameters :
- $type : the type of alert
- $externalid : the id of the "object" to query
In the table alert, a "id" is stored in the externalid field. This "id" is related to another table, depending on the type of the alert.
When type=issue, the id is related to a subscriptionid and this sub returns the name of the biblio.
When type=virtual, the id is related to a virtual shelf and this sub returns the name of the sub
