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.

190 Given a hash containing item column names as keys,
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.

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

360 This function updates an item record based on a supplied

362 This API is meant for the use of C<additem.pl>; for
363 other purposes, C<ModItem> should be used.
365 This function uses the hash %default_values_for_mod_from_marc,
366 which contains default values for item fields to
367 apply when modifying an item. This is needed beccause
368 if an item field's value is cleared, TransformMarcToKoha
369 does not include the column in the
370 hash that's passed to ModItem, which without
371 use of this hash makes it impossible to clear
372 an item field's value. See bug 2466.
374 Note that only columns that can be directly
375 changed from the cataloging and serials
376 item editors are included in this hash.

433 the MARC representation of the item.
435 The first argument is a hashref mapping from item column
436 names to the new values. The second and third arguments
437 are the biblionumber and itemnumber, respectively.
