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<$serial> is true, include serial publication data.
124 my ($itemnumber,$barcode, $serial) = @_;
125 my $dbh = C4::Context->dbh;

130 WHERE itemnumber = ?");

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

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