Looks books up in the reserves. C<$biblionumber> is the biblionumber
|
|
of the book to look up. C<$borrowernumber> is the borrower number of a
|
|
patron whose books to look up.
|
|
|
|
Either C<$biblionumber> or C<$borrowernumber> may be the empty string,
|
|
but not both. If both are specified, C<&FindReserves> looks up the
|
|
given book for the given patron. If only C<$biblionumber> is
|
|
specified, C<&FindReserves> looks up that book for all patrons. If
|
|
only C<$borrowernumber> is specified, C<&FindReserves> looks up all of
|
|
that patron's reserves. If neither is specified, C<&FindReserves>
|
|
barfs.
|
|
|
|
For each book thus found, C<&FindReserves> checks the reserve
|
|
constraints and does something I don't understand.
|
|
|
|
C<&FindReserves> returns a two-element array:
|
|
|
|
C<$count> is the number of elements in C<$results>.
|
|
|
|
C<$results> is a reference-to-array; each element is a
|
|
reference-to-hash, whose keys are (I think) all of the fields of the
|
|
reserves, borrowers, and biblio tables of the Koha database.

|
Find a book in the reserves.
|
|

|
C<$itemnumber> is the book's item number. C<$barcode> is its barcode.
|
|
Either one, but not both, may be false. If both are specified,
|
|
C<&CheckReserves> uses C<$itemnumber>.
|
|
|
|
$itemnubmer can be false, in which case uses the barcode. (Never uses
|
|
both. $itemnumber gets priority).
|
|
|
|
As I understand it, C<&CheckReserves> looks for the given item in the
|
|
reserves. If it is found, that's a match, and C<$status> is set to
|
|
C<Waiting>.
|
|
|
|
Otherwise, it finds the most important item in the reserves with the
|
|
same biblio number as this book (I'm not clear on this) and returns it
|
|
with C<$status> set to C<Reserved>.
|
|
|
|
C<&CheckReserves> returns a two-element list:
|
|
|
|
C<$status> is either C<Waiting>, C<Reserved> (see above), or 0.
|
|
|
|
C<$reserve> is the reserve item that matched. It is a
|
|
reference-to-hash whose keys are mostly the fields of the reserves
|
|
table in the Koha database.

I don't know what this does, because I don't understand how reserve
|
|
constraints work. I think the idea is that you reserve a particular
|
|
biblio, and the constraint allows you to restrict it to a given
|
|
biblioitem (e.g., if you want to borrow the audio book edition of "The
|
|
Prophet", rather than the first available publication).

|
|

C<@results> is an array of references-to-hash whose keys are mostly
|
|
fields from the reserves table of the Koha database, plus
|
|
C<biblioitemnumber>.
