69 C4::Items - item management functions
73 This module contains an API for manipulating item
74 records in Koha, and is used by cataloguing, circulation,
75 acquisitions, and serials management.
77 A Koha item record is stored in two places: the
78 items table and embedded in a MARC tag in the XML
79 version of the associated bib record in C<biblioitems.marcxml>.
80 This is done to allow the item information to be readily
81 indexed (e.g., by Zebra), but means that each item
82 modification transaction must keep the items table
83 and the MARC XML in sync at all times.
85 Consequently, all code that creates, modifies, or deletes
86 item records B<must> use an appropriate function from
87 C<C4::Items>. If no existing function is suitable, it is
88 better to add one to C<C4::Items> than to use add
89 one-off SQL statements to add or modify items.
91 The items table will be considered authoritative. In other
92 words, if there is ever a discrepancy between the items
93 table and the MARC XML, the items table should be considered
96 =head1 HISTORICAL NOTE
98 Most of the functions in C<C4::Items> were originally in
99 the C<C4::Biblio> module.
101 =head1 CORE EXPORTED FUNCTIONS
103 The following functions are meant for use by users
112 $item = GetItem($itemnumber,$barcode,$serial);
116 Return item information, for a given itemnumber or barcode.
117 The return value is a hashref mapping item column
118 names to values. If C<$serial> is true, include serial publication data.
123 my ($itemnumber,$barcode, $serial) = @_;
124 my $dbh = C4::Context->dbh;
127 my $sth = $dbh->prepare("
129 WHERE itemnumber = ?");
130 $sth->execute($itemnumber);

149 =head2 AddItemFromMarc
153 my ($biblionumber, $biblioitemnumber, $itemnumber)
154 = AddItemFromMarc($source_item_marc, $biblionumber);
158 Given a MARC::Record object containing an embedded item
159 record and a biblionumber, create a new item record.
163 sub AddItemFromMarc {
164 my ( $source_item_marc, $biblionumber ) = @_;

177 my ($biblionumber, $biblioitemnumber, $itemnumber)
178 = AddItem($item, $biblionumber[, $dbh, $frameworkcode, $original_item_marc]);
182 Given a hash containing item column names as keys,
183 create a new Koha item record.
185 The first two optional parameters (C<$dbh> and C<$frameworkcode>)
186 do not need to be supplied for general use; they exist
187 simply to allow them to be picked up from AddItemFromMarc.
189 The final optional parameter, C<$original_item_marc>, contains
190 a C<MARC::Record> object containing the original MARC item tag
191 that the item record came from, either from the item editor or
192 the source MARC record during a bulk import. This is used
193 to supply item-level subfields that are not directly mapped to
194 a column in the C<items> table but should remain available for
195 display and indexing.

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