In order to allow holds on items with notforloan = -1, processing of "unavailable" items in Search.pm was altered to exclude items with notforloan < 0. (See Bug 2341: items marked 'on order' not reserveable from search results). Doing so meant that such items were excluded from the list, in staff client search results, of items which are unavailable. This patch changes the logic of that processing so that items with notforloan < 0 are considered unavailable, but can still be placed on hold. To test, edit a record with a single item and view that record in search results. When the item is is on order (notforloan -1) it should say so. The holds link should be INactive only if: - item is withdrawn AND/OR - item is lost AND/OR - item is damaged (and AllowHoldsOnDamagedItems is off) AND/OR - item is not for loan, with notforloan > 0 Signed-off-by: Nicole C. Engard <nengard@bywatersolutions.com> All tests pass (note that a reindex is required if changing item statuses - which is why my first tests failed).

This function returns an array reference that contains the search parameters to be
|
|
passed to the Z39.50 search script (z3950_search.pl). The array elements
|
|
are hash refs whose keys are name, value and encvalue, and whose values are the
|
|
name of a search parameter, the value of that search parameter and the URL encoded
|
|
value of that parameter.
|
|
|
|
The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
|
|
|
|
The search parameter values are obtained from the bibliographic record whose
|
|
data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
|
|
|
|
If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
|
|
a general purpose search argument. In this case, the returned array contains only
|
|
entry: the key is 'title' and the value and encvalue are derived from $matchpoints.
|
|
|
|
If a search parameter value is undefined or empty, it is not included in the returned
|
|
array.
|
|
|
|
The returned array reference may be passed directly to the template parameters.
