 101 C4::Items - item management functions
 102
 103 =head1 DESCRIPTION
 104
 105 This module contains an API for manipulating item
 106 records in Koha, and is used by cataloguing, circulation,
 107 acquisitions, and serials management.
 108
 109 # FIXME This POD is not up-to-date
 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
 135
 136 The following functions are meant for use by users
 137 of C<C4::Items>
 138
 139 =cut
 140
 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.

 177
 178   CartToShelf($itemnumber);
 179
 180 Set the current shelving location of the item record
 181 to its stored permanent shelving location.  This is
 182 primarily used to indicate when an item whose current
 183 location is a special processing ('PROC') or shelving cart
 184 ('CART') location is back in the stacks.

 226       = AddItemFromMarc($source_item_marc, $biblionumber);

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

 252
 253 Given a hash containing item column names as keys,
 254 create a new Koha item record.
 255
 256 The first two optional parameters (C<$dbh> and C<$frameworkcode>)
 257 do not need to be supplied for general use; they exist
 258 simply to allow them to be picked up from AddItemFromMarc.
 259
 260 The final optional parameter, C<$unlinked_item_subfields>, contains
 261 an arrayref containing subfields present in the original MARC
 262 representation of the item (e.g., from the item editor) that are
 263 not mapped to C<items> columns directly but should instead
 264 be stored in C<items.more_subfields_xml> and included in
 265 the biblio items tag for display and indexing.

 314
 315 Efficiently create item records from a MARC biblio record with
 316 embedded item fields.  This routine is suitable for batch jobs.
 317
 318 This API assumes that the bib record has already been
 319 saved to the C<biblio> and C<biblioitems> tables.  It does
 320 not expect that C<biblio_metadata.metadata> is populated, but it
 321 will do so via a call to ModBibiloMarc.
 322
 323 The goal of this API is to have a similar effect to using AddBiblio
 324 and AddItems in succession, but without inefficient repeated
 325 parsing of the MARC XML bib record.
 326
 327 This function returns an arrayref of new itemsnumbers and an arrayref of item
 328 errors encountered during the processing.  Each entry in the errors
 329 list is a hashref containing the following keys:
 330
 331 =over
 332
 333 =item item_sequence
 334
 335 Sequence number of original item tag in the MARC record.
 336
 337 =item item_barcode
 338
 339 Item barcode, provide to assist in the construction of
 340 useful error messages.
 341
 342 =item error_code
 343
 344 Code representing the error condition.  Can be 'duplicate_barcode',
 345 'invalid_homebranch', or 'invalid_holdingbranch'.
 346
 347 =item error_information
 348
 349 Additional information appropriate to the error condition.

 421 This function updates an item record based on a supplied
 422 C<MARC::Record> object containing an embedded item field.
 423 This API is meant for the use of C<additem.pl>; for
 424 other purposes, C<ModItem> should be used.
 425
 426 This function uses the hash %default_values_for_mod_from_marc,
 427 which contains default values for item fields to
 428 apply when modifying an item.  This is needed because
 429 if an item field's value is cleared, TransformMarcToKoha
 430 does not include the column in the
 431 hash that's passed to ModItem, which without
 432 use of this hash makes it impossible to clear
 433 an item field's value.  See bug 2466.
 434
 435 Note that only columns that can be directly
 436 changed from the cataloging and serials
 437 item editors are included in this hash.

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

 792 Retrieve a list of title/authors/barcode/callnumber, for biblio inventory.
 793
 794 The sub returns a reference to a list of hashes, each containing
 795 itemnumber, author, title, barcode, item callnumber, and date last
 796 seen. It is ordered by callnumber then title.
 797
 798 The required minlocation & maxlocation parameters are used to specify a range of item callnumbers
 799 the datelastseen can be used to specify that you want to see items not seen since a past date only.
 800 offset & size can be used to retrieve only a part of the whole listing (defaut behaviour)
 801 $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.
 802
 803 $iTotalRecords is the number of rows that would have been returned without the $offset, $size limit clause

 985 contains a number of keys. Most of them are attributes from the

 993 The name (not the code) of the branch to which the book belongs.

 997 This is simply C<items.datelastseen>, except that while the date is
 998 stored in YYYY-MM-DD format in the database, here it is converted to
 999 DD/MM/YYYY format. A NULL date is returned as C<//>.

1526 independently.
1527
1528 Each key in the hash should be the name of a
1529 column (as named by TransformMarcToKoha).  Each
1530 value should be hashref whose keys are the
1531 columns on which the derived column depends.  The
1532 hashref should also contain a 'BUILDER' key

1578 This routine differs from C<_set_derived_columns_for_add>
1579 in that it needs to handle partial item records.  In other
1580 words, the caller of C<ModItem> may have supplied only one
1581 or two columns to be changed, so this function needs to
1582 determine whether any of the columns to be changed affect
1583 any of the derived columns.  Also, if a derived column
1584 depends on more than one column, but the caller is not
1585 changing all of then, this routine retrieves the unchanged
1586 values from the database in order to ensure a correct
1587 calculation.
