 104
 105 C4::Items - item management functions
 106
 107 =head1 DESCRIPTION
 108
 109 This module contains an API for manipulating item
 110 records in Koha, and is used by cataloguing, circulation,
 111 acquisitions, and serials management.
 112
 113 # FIXME This POD is not up-to-date
 114 A Koha item record is stored in two places: the
 115 items table and embedded in a MARC tag in the XML
 116 version of the associated bib record in C<biblioitems.marcxml>.
 117 This is done to allow the item information to be readily
 118 indexed (e.g., by Zebra), but means that each item
 119 modification transaction must keep the items table
 120 and the MARC XML in sync at all times.
 121
 122 Consequently, all code that creates, modifies, or deletes
 123 item records B<must> use an appropriate function from
 124 C<C4::Items>.  If no existing function is suitable, it is
 125 better to add one to C<C4::Items> than to use add
 126 one-off SQL statements to add or modify items.
 127
 128 The items table will be considered authoritative.  In other
 129 words, if there is ever a discrepancy between the items
 130 table and the MARC XML, the items table should be considered
 131 accurate.
 132
 133 =head1 HISTORICAL NOTE
 134
 135 Most of the functions in C<C4::Items> were originally in
 136 the C<C4::Biblio> module.
 137
 138 =head1 CORE EXPORTED FUNCTIONS
 139
 140 The following functions are meant for use by users
 141 of C<C4::Items>
 142
 143 =cut
 144
 145 =head2 GetItem
 146
 147   $item = GetItem($itemnumber,$barcode,$serial);
 148
 149 Return item information, for a given itemnumber or barcode.
 150 The return value is a hashref mapping item column
 151 names to values.  If C<$serial> is true, include serial publication data.

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

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

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

 318
 319 Efficiently create item records from a MARC biblio record with
 320 embedded item fields.  This routine is suitable for batch jobs.
 321
 322 This API assumes that the bib record has already been
 323 saved to the C<biblio> and C<biblioitems> tables.  It does
 324 not expect that C<biblio_metadata.metadata> is populated, but it
 325 will do so via a call to ModBibiloMarc.
 326
 327 The goal of this API is to have a similar effect to using AddBiblio
 328 and AddItems in succession, but without inefficient repeated
 329 parsing of the MARC XML bib record.
 330
 331 This function returns an arrayref of new itemsnumbers and an arrayref of item
 332 errors encountered during the processing.  Each entry in the errors
 333 list is a hashref containing the following keys:
 334
 335 =over
 336
 337 =item item_sequence
 338
 339 Sequence number of original item tag in the MARC record.
 340
 341 =item item_barcode
 342
 343 Item barcode, provide to assist in the construction of
 344 useful error messages.
 345
 346 =item error_code
 347
 348 Code representing the error condition.  Can be 'duplicate_barcode',
 349 'invalid_homebranch', or 'invalid_holdingbranch'.
 350
 351 =item error_information
 352
 353 Additional information appropriate to the error condition.

 424
 425 This function updates an item record based on a supplied
 426 C<MARC::Record> object containing an embedded item field.
 427 This API is meant for the use of C<additem.pl>; for
 428 other purposes, C<ModItem> should be used.
 429
 430 This function uses the hash %default_values_for_mod_from_marc,
 431 which contains default values for item fields to
 432 apply when modifying an item.  This is needed because
 433 if an item field's value is cleared, TransformMarcToKoha
 434 does not include the column in the
 435 hash that's passed to ModItem, which without
 436 use of this hash makes it impossible to clear
 437 an item field's value.  See bug 2466.
 438
 439 Note that only columns that can be directly
 440 changed from the cataloging and serials
 441 item editors are included in this hash.

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

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

 950 the datelastseen can be used to specify that you want to see items not seen since a past date only.
 951 offset & size can be used to retrieve only a part of the whole listing (defaut behaviour)
 952 $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.
 953
 954 $iTotalRecords is the number of rows that would have been returned without the $offset, $size limit clause

1733 This hash keeps track of item columns that
1734 are strictly derived from other columns in
1735 the item record and are not meant to be set
1736 independently.
1737
1738 Each key in the hash should be the name of a
1739 column (as named by TransformMarcToKoha).  Each
1740 value should be hashref whose keys are the
1741 columns on which the derived column depends.  The
1742 hashref should also contain a 'BUILDER' key
1743 that is a reference to a sub that calculates
1744 the derived value.

1788 This routine differs from C<_set_derived_columns_for_add>
1789 in that it needs to handle partial item records.  In other
1790 words, the caller of C<ModItem> may have supplied only one
1791 or two columns to be changed, so this function needs to
1792 determine whether any of the columns to be changed affect
1793 any of the derived columns.  Also, if a derived column
1794 depends on more than one column, but the caller is not
1795 changing all of then, this routine retrieves the unchanged
1796 values from the database in order to ensure a correct
1797 calculation.
