  84 =head1 NAME
  85
  86 C4::Items - item management functions
  87
  88 =head1 DESCRIPTION
  89
  90 This module contains an API for manipulating item
  91 records in Koha, and is used by cataloguing, circulation,
  92 acquisitions, and serials management.
  93
  94 # FIXME This POD is not up-to-date
  95 A Koha item record is stored in two places: the
  96 items table and embedded in a MARC tag in the XML
  97 version of the associated bib record in C<biblioitems.marcxml>.
  98 This is done to allow the item information to be readily
  99 indexed (e.g., by Zebra), but means that each item
 100 modification transaction must keep the items table
 101 and the MARC XML in sync at all times.
 102
 103 Consequently, all code that creates, modifies, or deletes
 104 item records B<must> use an appropriate function from
 105 C<C4::Items>.  If no existing function is suitable, it is
 106 better to add one to C<C4::Items> than to use add
 107 one-off SQL statements to add or modify items.
 108
 109 The items table will be considered authoritative.  In other
 110 words, if there is ever a discrepancy between the items
 111 table and the MARC XML, the items table should be considered
 112 accurate.
 113
 114 =head1 HISTORICAL NOTE
 115
 116 Most of the functions in C<C4::Items> were originally in
 117 the C<C4::Biblio> module.
 118
 119 =head1 CORE EXPORTED FUNCTIONS
 120
 121 The following functions are meant for use by users
 122 of C<C4::Items>

 125
 126 =head2 GetItem
 127
 128   $item = GetItem($itemnumber,$barcode,$serial);
 129
 130 Return item information, for a given itemnumber or barcode.
 131 The return value is a hashref mapping item column
 132 names to values.  If C<$serial> is true, include serial publication data.

 162
 163   CartToShelf($itemnumber);
 164
 165 Set the current shelving location of the item record
 166 to its stored permanent shelving location.  This is
 167 primarily used to indicate when an item whose current
 168 location is a special processing ('PROC') or shelving cart
 169 ('CART') location is back in the stacks.

 214 record and a biblionumber, create a new item record.

 237
 238 Given a hash containing item column names as keys,
 239 create a new Koha item record.
 240
 241 The first two optional parameters (C<$dbh> and C<$frameworkcode>)
 242 do not need to be supplied for general use; they exist
 243 simply to allow them to be picked up from AddItemFromMarc.
 244
 245 The final optional parameter, C<$unlinked_item_subfields>, contains
 246 an arrayref containing subfields present in the original MARC
 247 representation of the item (e.g., from the item editor) that are
 248 not mapped to C<items> columns directly but should instead
 249 be stored in C<items.more_subfields_xml> and included in
 250 the biblio items tag for display and indexing.

 300 Efficiently create item records from a MARC biblio record with
 301 embedded item fields.  This routine is suitable for batch jobs.
 302
 303 This API assumes that the bib record has already been
 304 saved to the C<biblio> and C<biblioitems> tables.  It does
 305 not expect that C<biblio_metadata.metadata> is populated, but it
 306 will do so via a call to ModBibiloMarc.
 307
 308 The goal of this API is to have a similar effect to using AddBiblio
 309 and AddItems in succession, but without inefficient repeated
 310 parsing of the MARC XML bib record.
 311
 312 This function returns an arrayref of new itemsnumbers and an arrayref of item
 313 errors encountered during the processing.  Each entry in the errors
 314 list is a hashref containing the following keys:
 315
 316 =over
 317
 318 =item item_sequence
 319
 320 Sequence number of original item tag in the MARC record.
 321
 322 =item item_barcode
 323
 324 Item barcode, provide to assist in the construction of
 325 useful error messages.
 326
 327 =item error_code
 328
 329 Code representing the error condition.  Can be 'duplicate_barcode',
 330 'invalid_homebranch', or 'invalid_holdingbranch'.
 331
 332 =item error_information
 333
 334 Additional information appropriate to the error condition.

 406 This function updates an item record based on a supplied
 407 C<MARC::Record> object containing an embedded item field.
 408 This API is meant for the use of C<additem.pl>; for
 409 other purposes, C<ModItem> should be used.
 410
 411 This function uses the hash %default_values_for_mod_from_marc,
 412 which contains default values for item fields to
 413 apply when modifying an item.  This is needed because
 414 if an item field's value is cleared, TransformMarcToKoha
 415 does not include the column in the
 416 hash that's passed to ModItem, which without
 417 use of this hash makes it impossible to clear
 418 an item field's value.  See bug 2466.
 419
 420 Note that only columns that can be directly
 421 changed from the cataloging and serials
 422 item editors are included in this hash.

 516 The first argument is a hashref mapping from item column
 517 names to the new values.  The second and third arguments

 526 be stored in C<items.more_subfields_xml> and included in
 527 the biblio items tag for display and indexing.

 529 If one of the changed columns is used to calculate
 530 the derived value of a column such as C<items.cn_sort>,
 531 this routine will perform the necessary calculation
 532 and set the value.

 788
 789 The sub returns a reference to a list of hashes, each containing
 790 itemnumber, author, title, barcode, item callnumber, and date last
 791 seen. It is ordered by callnumber then title.
 792
 793 The required minlocation & maxlocation parameters are used to specify a range of item callnumbers
 794 the datelastseen can be used to specify that you want to see items not seen since a past date only.
 795 offset & size can be used to retrieve only a part of the whole listing (defaut behaviour)
 796 $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.

 798 $iTotalRecords is the number of rows that would have been returned without the $offset, $size limit clause

 937 C<GetItemsInfo> returns a list of references-to-hash. Each element
 938 contains a number of keys. Most of them are attributes from the
 939 C<biblio>, C<biblioitems>, C<items>, and C<itemtypes> tables in the
 940 Koha database. Other keys include:
 941
 942 =over 2
 943
 944 =item C<$data-E<gt>{branchname}>
 945
 946 The name (not the code) of the branch to which the book belongs.
 947
 948 =item C<$data-E<gt>{datelastseen}>
 949
 950 This is simply C<items.datelastseen>, except that while the date is
 951 stored in YYYY-MM-DD format in the database, here it is converted to
 952 DD/MM/YYYY format. A NULL date is returned as C<//>.
 953
 954 =item C<$data-E<gt>{datedue}>
 955
 956 =item C<$data-E<gt>{class}>
 957
 958 This is the concatenation of C<biblioitems.classification>, the book's
 959 Dewey code, and C<biblioitems.subclass>.
 960
 961 =item C<$data-E<gt>{ocount}>
 962
 963 I think this is the number of copies of the book available.

1307 The following functions, while part of the public API,
1308 are not exported.  This is generally because they are
1309 meant to be used by only one script for a specific
1310 purpose, and should not be used in any other context
1311 without careful thought.

1381
1382 This hash keeps track of item columns that
1383 are strictly derived from other columns in
1384 the item record and are not meant to be set
1385 independently.
1386
1387 Each key in the hash should be the name of a
1388 column (as named by TransformMarcToKoha).  Each
1389 value should be hashref whose keys are the
1390 columns on which the derived column depends.  The
1391 hashref should also contain a 'BUILDER' key
1392 that is a reference to a sub that calculates
1393 the derived value.

1433 Given an item hash representing a new item to be modified.
1434 calculate any derived columns.  Currently the only
1435 such column is C<items.cn_sort>.
1436
1437 This routine differs from C<_set_derived_columns_for_add>
1438 in that it needs to handle partial item records.  In other
1439 words, the caller of C<ModItem> may have supplied only one
1440 or two columns to be changed, so this function needs to
1441 determine whether any of the columns to be changed affect
1442 any of the derived columns.  Also, if a derived column
1443 depends on more than one column, but the caller is not
1444 changing all of then, this routine retrieves the unchanged
1445 values from the database in order to ensure a correct
1446 calculation.
