71 C4::Items - item management functions
75 This module contains an API for manipulating item
76 records in Koha, and is used by cataloguing, circulation,
77 acquisitions, and serials management.
79 A Koha item record is stored in two places: the
80 items table and embedded in a MARC tag in the XML
81 version of the associated bib record in C<biblioitems.marcxml>.
82 This is done to allow the item information to be readily
83 indexed (e.g., by Zebra), but means that each item
84 modification transaction must keep the items table
85 and the MARC XML in sync at all times.
87 Consequently, all code that creates, modifies, or deletes
88 item records B<must> use an appropriate function from
89 C<C4::Items>. If no existing function is suitable, it is
90 better to add one to C<C4::Items> than to use add
91 one-off SQL statements to add or modify items.
93 The items table will be considered authoritative. In other
94 words, if there is ever a discrepancy between the items
95 table and the MARC XML, the items table should be considered
98 =head1 HISTORICAL NOTE
100 Most of the functions in C<C4::Items> were originally in
101 the C<C4::Biblio> module.
103 =head1 CORE EXPORTED FUNCTIONS
105 The following functions are meant for use by users
114 $item = GetItem($itemnumber,$barcode,$serial);
118 Return item information, for a given itemnumber or barcode.
119 The return value is a hashref mapping item column
120 names to values. If C<$serial> is true, include serial publication data.
125 my ($itemnumber,$barcode, $serial) = @_;

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

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

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

1624 The following functions are not meant to be called

1626 the inner workings of C<C4::Items>.

1632 This hash keeps track of item columns that
1633 are strictly derived from other columns in
1634 the item record and are not meant to be set
1637 Each key in the hash should be the name of a
1638 column (as named by TransformMarcToKoha). Each
1639 value should be hashref whose keys are the
1640 columns on which the derived column depends. The
1641 hashref should also contain a 'BUILDER' key

1651 'BUILDER' => \&_calc_items_cn_sort,
1655 =head2 _set_derived_columns_for_add
1659 _set_derived_column_for_add($item);
1663 Given an item hash representing a new item to be added,
1664 calculate any derived columns. Currently the only
1665 such column is C<items.cn_sort>.

1692 calculate any derived columns. Currently the only
1693 such column is C<items.cn_sort>.
1695 This routine differs from C<_set_derived_columns_for_add>
1696 in that it needs to handle partial item records. In other
1697 words, the caller of C<ModItem> may have supplied only one
1698 or two columns to be changed, so this function needs to
1699 determine whether any of the columns to be changed affect
1700 any of the derived columns. Also, if a derived column
1701 depends on more than one column, but the caller is not
1702 changing all of then, this routine retrieves the unchanged
