C4::VirtualShelves - Functions for manipulating Koha virtual virtualshelves

use C4::VirtualShelves;

|
|
|
=head1 DESCRIPTION
|
|
|
|
This module provides functions for manipulating virtual virtualshelves,
|
|
including creating and deleting virtualshelves, and adding and removing
|
|
items to and from virtualshelves.

|
$shelflist = &GetShelves($owner, $mincategory);
|
|
($shelfnumber, $shelfhash) = each %{$shelflist};
|
|
|
|
Looks up the virtual virtualshelves, and returns a summary. C<$shelflist>
|
|
is a reference-to-hash. The keys are the virtualshelves numbers
|
|
(C<$shelfnumber>, above), and the values (C<$shelfhash>, above) are
|
|
themselves references-to-hash, with the following keys:
|
|
|
|
C<mincategory> : 2 if the list is for "look". 3 if the list is for "Select virtualshelves for adding a virtual".
|
|
virtualshelves of the owner are always selected, whatever the category
|
|
|
|
=over 4
|
|
|
|
=item C<$shelfhash-E<gt>{shelfname}>
|
|
|
|
A string. The name of the shelf.
|
|
|
|
=item C<$shelfhash-E<gt>{count}>
|
|
|
|
The number of virtuals on that virtualshelves.
