 100 C4::Items - item management functions
 101
 102 =head1 DESCRIPTION
 103
 104 This module contains an API for manipulating item
 105 records in Koha, and is used by cataloguing, circulation,
 106 acquisitions, and serials management.
 107
 108 A Koha item record is stored in two places: the
 109 items table and embedded in a MARC tag in the XML
 110 version of the associated bib record in C<biblioitems.marcxml>.
 111 This is done to allow the item information to be readily
 112 indexed (e.g., by Zebra), but means that each item
 113 modification transaction must keep the items table
 114 and the MARC XML in sync at all times.
 115
 116 Consequently, all code that creates, modifies, or deletes
 117 item records B<must> use an appropriate function from
 118 C<C4::Items>.  If no existing function is suitable, it is
 119 better to add one to C<C4::Items> than to use add
 120 one-off SQL statements to add or modify items.
 121
 122 The items table will be considered authoritative.  In other
 123 words, if there is ever a discrepancy between the items
 124 table and the MARC XML, the items table should be considered
 125 accurate.
 126
 127 =head1 HISTORICAL NOTE
 128
 129 Most of the functions in C<C4::Items> were originally in
 130 the C<C4::Biblio> module.
 131
 132 =head1 CORE EXPORTED FUNCTIONS

 139 =head2 GetItem
 140
 141   $item = GetItem($itemnumber,$barcode,$serial);
 142
 143 Return item information, for a given itemnumber or barcode.
 144 The return value is a hashref mapping item column
 145 names to values.  If C<$serial> is true, include serial publication data.

 191 Set the current shelving location of the item record
 192 to its stored permanent shelving location.  This is
 193 primarily used to indicate when an item whose current
 194 location is a special processing ('PROC') or shelving cart
 195 ('CART') location is back in the stacks.

 264 Given a hash containing item column names as keys,
 265 create a new Koha item record.
 266
 267 The first two optional parameters (C<$dbh> and C<$frameworkcode>)
 268 do not need to be supplied for general use; they exist
 269 simply to allow them to be picked up from AddItemFromMarc.
 270
 271 The final optional parameter, C<$unlinked_item_subfields>, contains
 272 an arrayref containing subfields present in the original MARC
 273 representation of the item (e.g., from the item editor) that are
 274 not mapped to C<items> columns directly but should instead
 275 be stored in C<items.more_subfields_xml> and included in
 276 the biblio items tag for display and indexing.

 321
 322 Efficiently create item records from a MARC biblio record with
 323 embedded item fields.  This routine is suitable for batch jobs.
 324
 325 This API assumes that the bib record has already been
 326 saved to the C<biblio> and C<biblioitems> tables.  It does
 327 not expect that C<biblioitems.marc> and C<biblioitems.marcxml>
 328 are populated, but it will do so via a call to ModBibiloMarc.
 329
 330 The goal of this API is to have a similar effect to using AddBiblio
 331 and AddItems in succession, but without inefficient repeated
 332 parsing of the MARC XML bib record.
 333
 334 This function returns an arrayref of new itemsnumbers and an arrayref of item
 335 errors encountered during the processing.  Each entry in the errors
 336 list is a hashref containing the following keys:
 337
 338 =over
 339
 340 =item item_sequence
 341
 342 Sequence number of original item tag in the MARC record.
 343
 344 =item item_barcode
 345
 346 Item barcode, provide to assist in the construction of
 347 useful error messages.
 348
 349 =item error_code
 350
 351 Code representing the error condition.  Can be 'duplicate_barcode',
 352 'invalid_homebranch', or 'invalid_holdingbranch'.
 353
 354 =item error_information
 355
 356 Additional information appropriate to the error condition.

 427
 428 This function updates an item record based on a supplied
 429 C<MARC::Record> object containing an embedded item field.
 430 This API is meant for the use of C<additem.pl>; for
 431 other purposes, C<ModItem> should be used.
 432
 433 This function uses the hash %default_values_for_mod_from_marc,
 434 which contains default values for item fields to
 435 apply when modifying an item.  This is needed because
 436 if an item field's value is cleared, TransformMarcToKoha
 437 does not include the column in the
 438 hash that's passed to ModItem, which without
 439 use of this hash makes it impossible to clear
 440 an item field's value.  See bug 2466.
 441
 442 Note that only columns that can be directly
 443 changed from the cataloging and serials
 444 item editors are included in this hash.

 525 Change one or more columns in an item record and update
 526 the MARC representation of the item.
 527
 528 The first argument is a hashref mapping from item column
 529 names to the new values.  The second and third arguments
 530 are the biblionumber and itemnumber, respectively.
 531
 532 The fourth, optional parameter, C<$unlinked_item_subfields>, contains
 533 an arrayref containing subfields present in the original MARC
 534 representation of the item (e.g., from the item editor) that are
 535 not mapped to C<items> columns directly but should instead
 536 be stored in C<items.more_subfields_xml> and included in
 537 the biblio items tag for display and indexing.
 538
 539 If one of the changed columns is used to calculate
 540 the derived value of a column such as C<items.cn_sort>,
 541 this routine will perform the necessary calculation
 542 and set the value.

1045 itemnumber, author, title, barcode, item callnumber, and date last
1046 seen. It is ordered by callnumber then title.
1047
1048 The required minlocation & maxlocation parameters are used to specify a range of item callnumbers
1049 the datelastseen can be used to specify that you want to see items not seen since a past date only.
1050 offset & size can be used to retrieve only a part of the whole listing (defaut behaviour)
1051 $statushash requires a hashref that has the authorized values fieldname (intems.notforloan, etc...) as keys, and an arrayref of statuscodes we are searching for as values.
1052
1053 $iTotalRecords is the number of rows that would have been returned without the $offset, $size limit clause

1924
1925 This hash keeps track of item columns that
1926 are strictly derived from other columns in
1927 the item record and are not meant to be set
1928 independently.
1929
1930 Each key in the hash should be the name of a
1931 column (as named by TransformMarcToKoha).  Each
1932 value should be hashref whose keys are the
1933 columns on which the derived column depends.  The
1934 hashref should also contain a 'BUILDER' key
1935 that is a reference to a sub that calculates
1936 the derived value.

1977 calculate any derived columns.  Currently the only
1978 such column is C<items.cn_sort>.
1979
1980 This routine differs from C<_set_derived_columns_for_add>
1981 in that it needs to handle partial item records.  In other
1982 words, the caller of C<ModItem> may have supplied only one
1983 or two columns to be changed, so this function needs to
1984 determine whether any of the columns to be changed affect
1985 any of the derived columns.  Also, if a derived column
1986 depends on more than one column, but the caller is not
1987 changing all of then, this routine retrieves the unchanged
1988 values from the database in order to ensure a correct
1989 calculation.
