 102 C4::Items - item management functions
 103
 104 =head1 DESCRIPTION
 105
 106 This module contains an API for manipulating item
 107 records in Koha, and is used by cataloguing, circulation,
 108 acquisitions, and serials management.
 109
 110 A Koha item record is stored in two places: the
 111 items table and embedded in a MARC tag in the XML
 112 version of the associated bib record in C<biblioitems.marcxml>.
 113 This is done to allow the item information to be readily
 114 indexed (e.g., by Zebra), but means that each item
 115 modification transaction must keep the items table
 116 and the MARC XML in sync at all times.
 117
 118 Consequently, all code that creates, modifies, or deletes
 119 item records B<must> use an appropriate function from
 120 C<C4::Items>.  If no existing function is suitable, it is
 121 better to add one to C<C4::Items> than to use add
 122 one-off SQL statements to add or modify items.
 123
 124 The items table will be considered authoritative.  In other
 125 words, if there is ever a discrepancy between the items
 126 table and the MARC XML, the items table should be considered
 127 accurate.
 128
 129 =head1 HISTORICAL NOTE
 130
 131 Most of the functions in C<C4::Items> were originally in
 132 the C<C4::Biblio> module.
 133
 134 =head1 CORE EXPORTED FUNCTIONS

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

 194 to its stored permanent shelving location.  This is
 195 primarily used to indicate when an item whose current

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

 327
 328 Efficiently create item records from a MARC biblio record with
 329 embedded item fields.  This routine is suitable for batch jobs.
 330
 331 This API assumes that the bib record has already been
 332 saved to the C<biblio> and C<biblioitems> tables.  It does
 333 not expect that C<biblioitems.marc> and C<biblioitems.marcxml>
 334 are populated, but it will do so via a call to ModBibiloMarc.
 335
 336 The goal of this API is to have a similar effect to using AddBiblio
 337 and AddItems in succession, but without inefficient repeated
 338 parsing of the MARC XML bib record.
 339
 340 This function returns an arrayref of new itemsnumbers and an arrayref of item
 341 errors encountered during the processing.  Each entry in the errors
 342 list is a hashref containing the following keys:
 343
 344 =over
 345
 346 =item item_sequence
 347
 348 Sequence number of original item tag in the MARC record.
 349
 350 =item item_barcode
 351
 352 Item barcode, provide to assist in the construction of
 353 useful error messages.
 354
 355 =item error_code
 356
 357 Code representing the error condition.  Can be 'duplicate_barcode',
 358 'invalid_homebranch', or 'invalid_holdingbranch'.
 359
 360 =item error_information
 361
 362 Additional information appropriate to the error condition.

 433
 434 This function updates an item record based on a supplied
 435 C<MARC::Record> object containing an embedded item field.
 436 This API is meant for the use of C<additem.pl>; for
 437 other purposes, C<ModItem> should be used.
 438
 439 This function uses the hash %default_values_for_mod_from_marc,
 440 which contains default values for item fields to
 441 apply when modifying an item.  This is needed because
 442 if an item field's value is cleared, TransformMarcToKoha
 443 does not include the column in the
 444 hash that's passed to ModItem, which without
 445 use of this hash makes it impossible to clear
 446 an item field's value.  See bug 2466.
 447
 448 Note that only columns that can be directly
 449 changed from the cataloging and serials
 450 item editors are included in this hash.

 536 Change one or more columns in an item record and update

 539 The first argument is a hashref mapping from item column
 540 names to the new values.  The second and third arguments
 541 are the biblionumber and itemnumber, respectively.
 542
 543 The fourth, optional parameter, C<$unlinked_item_subfields>, contains
 544 an arrayref containing subfields present in the original MARC
 545 representation of the item (e.g., from the item editor) that are
 546 not mapped to C<items> columns directly but should instead
 547 be stored in C<items.more_subfields_xml> and included in
 548 the biblio items tag for display and indexing.
 549
 550 If one of the changed columns is used to calculate
 551 the derived value of a column such as C<items.cn_sort>,
 552 this routine will perform the necessary calculation
 553 and set the value.

1053 The sub returns a reference to a list of hashes, each containing
1054 itemnumber, author, title, barcode, item callnumber, and date last
1055 seen. It is ordered by callnumber then title.
1056
1057 The required minlocation & maxlocation parameters are used to specify a range of item callnumbers
1058 the datelastseen can be used to specify that you want to see items not seen since a past date only.
1059 offset & size can be used to retrieve only a part of the whole listing (defaut behaviour)
1060 $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.
1061
1062 $iTotalRecords is the number of rows that would have been returned without the $offset, $size limit clause

1844
1845 This hash keeps track of item columns that
1846 are strictly derived from other columns in
1847 the item record and are not meant to be set
1848 independently.
1849
1850 Each key in the hash should be the name of a
1851 column (as named by TransformMarcToKoha).  Each
1852 value should be hashref whose keys are the
1853 columns on which the derived column depends.  The
1854 hashref should also contain a 'BUILDER' key
1855 that is a reference to a sub that calculates
1856 the derived value.

1897 calculate any derived columns.  Currently the only
1898 such column is C<items.cn_sort>.
1899
1900 This routine differs from C<_set_derived_columns_for_add>
1901 in that it needs to handle partial item records.  In other
1902 words, the caller of C<ModItem> may have supplied only one
1903 or two columns to be changed, so this function needs to
1904 determine whether any of the columns to be changed affect
1905 any of the derived columns.  Also, if a derived column
1906 depends on more than one column, but the caller is not
1907 changing all of then, this routine retrieves the unchanged
1908 values from the database in order to ensure a correct
1909 calculation.
