70 C4::Items - item management functions
74 This module contains an API for manipulating item
75 records in Koha, and is used by cataloguing, circulation,
76 acquisitions, and serials management.
78 A Koha item record is stored in two places: the
79 items table and embedded in a MARC tag in the XML
80 version of the associated bib record in C<biblioitems.marcxml>.
81 This is done to allow the item information to be readily
82 indexed (e.g., by Zebra), but means that each item
83 modification transaction must keep the items table
84 and the MARC XML in sync at all times.
86 Consequently, all code that creates, modifies, or deletes
87 item records B<must> use an appropriate function from
88 C<C4::Items>. If no existing function is suitable, it is
89 better to add one to C<C4::Items> than to use add
90 one-off SQL statements to add or modify items.
92 The items table will be considered authoritative. In other
93 words, if there is ever a discrepancy between the items
94 table and the MARC XML, the items table should be considered
97 =head1 HISTORICAL NOTE
99 Most of the functions in C<C4::Items> were originally in
100 the C<C4::Biblio> module.
102 =head1 CORE EXPORTED FUNCTIONS
104 The following functions are meant for use by users
113 $item = GetItem($itemnumber,$barcode,$serial);
117 Return item information, for a given itemnumber or barcode.
118 The return value is a hashref mapping item column
119 names to values. If C<$serial> is true, include serial publication data.

191 create a new Koha item record.
193 The first two optional parameters (C<$dbh> and C<$frameworkcode>)
194 do not need to be supplied for general use; they exist
195 simply to allow them to be picked up from AddItemFromMarc.
197 The final optional parameter, C<$unlinked_item_subfields>, contains
198 an arrayref containing subfields present in the original MARC
199 representation of the item (e.g., from the item editor) that are
200 not mapped to C<items> columns directly but should instead
201 be stored in C<items.more_subfields_xml> and included in
202 the biblio items tag for display and indexing.

248 Efficiently create item records from a MARC biblio record with
249 embedded item fields. This routine is suitable for batch jobs.
251 This API assumes that the bib record has already been
252 saved to the C<biblio> and C<biblioitems> tables. It does
253 not expect that C<biblioitems.marc> and C<biblioitems.marcxml>
254 are populated, but it will do so via a call to ModBibiloMarc.
256 The goal of this API is to have a similar effect to using AddBiblio
257 and AddItems in succession, but without inefficient repeated
258 parsing of the MARC XML bib record.
260 This function returns an arrayref of new itemsnumbers and an arrayref of item
261 errors encountered during the processing. Each entry in the errors
262 list is a hashref containing the following keys:
268 Sequence number of original item tag in the MARC record.
272 Item barcode, provide to assist in the construction of
273 useful error messages.
275 =item error_condition
277 Code representing the error condition. Can be 'duplicate_barcode',
278 'invalid_homebranch', or 'invalid_holdingbranch'.
280 =item error_information
282 Additional information appropriate to the error condition.
