  91 C4::Items - item management functions
  92
  93 =head1 DESCRIPTION
  94
  95 This module contains an API for manipulating item
  96 records in Koha, and is used by cataloguing, circulation,
  97 acquisitions, and serials management.
  98
  99 A Koha item record is stored in two places: the
 100 items table and embedded in a MARC tag in the XML
 101 version of the associated bib record in C<biblioitems.marcxml>.
 102 This is done to allow the item information to be readily
 103 indexed (e.g., by Zebra), but means that each item
 104 modification transaction must keep the items table
 105 and the MARC XML in sync at all times.
 106
 107 Consequently, all code that creates, modifies, or deletes
 108 item records B<must> use an appropriate function from
 109 C<C4::Items>.  If no existing function is suitable, it is
 110 better to add one to C<C4::Items> than to use add
 111 one-off SQL statements to add or modify items.
 112
 113 The items table will be considered authoritative.  In other
 114 words, if there is ever a discrepancy between the items
 115 table and the MARC XML, the items table should be considered
 116 accurate.
 117
 118 =head1 HISTORICAL NOTE
 119
 120 Most of the functions in C<C4::Items> were originally in
 121 the C<C4::Biblio> module.
 122
 123 =head1 CORE EXPORTED FUNCTIONS
 124
 125 The following functions are meant for use by users
 126 of C<C4::Items>
 127

 130 =head2 GetItem
 131
 132   $item = GetItem($itemnumber,$barcode,$serial);
 133
 134 Return item information, for a given itemnumber or barcode.
 135 The return value is a hashref mapping item column
 136 names to values.  If C<$serial> is true, include serial publication data.

 172 =head2 CartToShelf
 173
 174   CartToShelf($itemnumber);
 175
 176 Set the current shelving location of the item record
 177 to its stored permanent shelving location.  This is
 178 primarily used to indicate when an item whose current
 179 location is a special processing ('PROC') or shelving cart
 180 ('CART') location is back in the stacks.

 226 Given a hash containing item column names as keys,
 227 create a new Koha item record.
 228
 229 The first two optional parameters (C<$dbh> and C<$frameworkcode>)
 230 do not need to be supplied for general use; they exist
 231 simply to allow them to be picked up from AddItemFromMarc.
 232
 233 The final optional parameter, C<$unlinked_item_subfields>, contains
 234 an arrayref containing subfields present in the original MARC
 235 representation of the item (e.g., from the item editor) that are
 236 not mapped to C<items> columns directly but should instead
 237 be stored in C<items.more_subfields_xml> and included in
 238 the biblio items tag for display and indexing.

 283
 284 Efficiently create item records from a MARC biblio record with
 285 embedded item fields.  This routine is suitable for batch jobs.
 286
 287 This API assumes that the bib record has already been
 288 saved to the C<biblio> and C<biblioitems> tables.  It does
 289 not expect that C<biblioitems.marc> and C<biblioitems.marcxml>
 290 are populated, but it will do so via a call to ModBibiloMarc.
 291
 292 The goal of this API is to have a similar effect to using AddBiblio
 293 and AddItems in succession, but without inefficient repeated
 294 parsing of the MARC XML bib record.
 295
 296 This function returns an arrayref of new itemsnumbers and an arrayref of item
 297 errors encountered during the processing.  Each entry in the errors
 298 list is a hashref containing the following keys:
 299
 300 =over
 301
 302 =item item_sequence
 303
 304 Sequence number of original item tag in the MARC record.
 305
 306 =item item_barcode
 307
 308 Item barcode, provide to assist in the construction of
 309 useful error messages.
 310
 311 =item error_condition
 312
 313 Code representing the error condition.  Can be 'duplicate_barcode',
 314 'invalid_homebranch', or 'invalid_holdingbranch'.
 315
 316 =item error_information
 317
 318 Additional information appropriate to the error condition.

 386
 387 This function updates an item record based on a supplied
 388 C<MARC::Record> object containing an embedded item field.
 389 This API is meant for the use of C<additem.pl>; for
 390 other purposes, C<ModItem> should be used.
 391
 392 This function uses the hash %default_values_for_mod_from_marc,
 393 which contains default values for item fields to
 394 apply when modifying an item.  This is needed beccause
 395 if an item field's value is cleared, TransformMarcToKoha
 396 does not include the column in the
 397 hash that's passed to ModItem, which without
 398 use of this hash makes it impossible to clear
 399 an item field's value.  See bug 2466.
 400
 401 Note that only columns that can be directly
 402 changed from the cataloging and serials
 403 item editors are included in this hash.

 466
 467 The first argument is a hashref mapping from item column
 468 names to the new values.  The second and third arguments
 469 are the biblionumber and itemnumber, respectively.
 470
 471 The fourth, optional parameter, C<$unlinked_item_subfields>, contains
 472 an arrayref containing subfields present in the original MARC
 473 representation of the item (e.g., from the item editor) that are
 474 not mapped to C<items> columns directly but should instead
 475 be stored in C<items.more_subfields_xml> and included in
 476 the biblio items tag for display and indexing.
 477
 478 If one of the changed columns is used to calculate
 479 the derived value of a column such as C<items.cn_sort>,
 480 this routine will perform the necessary calculation
 481 and set the value.

 949 The required minlocation & maxlocation parameters are used to specify a range of item callnumbers
 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.

1719 find a list of icons that are appropriate for display based on the

1722 parameters: listref of authorised values, such as comes from
1723 get_item_authorised_values or
1724 from C4::Biblio::get_biblio_authorised_values
1725
1726 returns: listref of hashrefs for each image. Each hashref looks like this:
1727
1728       { imageurl => '/intranet-tmpl/prog/img/itemtypeimg/npl/WEB.gif',
1729         label    => '',

1731         value    => '', }
1732
1733 Notes: Currently, I put on the full path to the images on the staff
1734 side. This should either be configurable or not done at all. Since I
1735 have to deal with 'intranet' or 'opac' in
1736 get_biblio_authorised_values, perhaps I should be passing it in.

1838
1839 This hash keeps track of item columns that
1840 are strictly derived from other columns in
1841 the item record and are not meant to be set
1842 independently.
1843
1844 Each key in the hash should be the name of a
1845 column (as named by TransformMarcToKoha).  Each
1846 value should be hashref whose keys are the
1847 columns on which the derived column depends.  The
1848 hashref should also contain a 'BUILDER' key
1849 that is a reference to a sub that calculates
1850 the derived value.

1891 calculate any derived columns.  Currently the only
1892 such column is C<items.cn_sort>.
1893
1894 This routine differs from C<_set_derived_columns_for_add>
1895 in that it needs to handle partial item records.  In other
1896 words, the caller of C<ModItem> may have supplied only one
1897 or two columns to be changed, so this function needs to
1898 determine whether any of the columns to be changed affect
1899 any of the derived columns.  Also, if a derived column
1900 depends on more than one column, but the caller is not
1901 changing all of then, this routine retrieves the unchanged
1902 values from the database in order to ensure a correct
1903 calculation.
