A Koha item record is stored in two places: the items table and embedded in a MARC tag in the XML version of the associated bib record in C. This is done to allow the item information to be readily indexed (e.g., by Zebra), but means that each item modification transaction must keep the items table and the MARC XML in sync at all times. Consequently, all code that creates, modifies, or deletes item records B use an appropriate function from C. If no existing function is suitable, it is better to add one to C than to use add one-off SQL statements to add or modify items. The items table will be considered authoritative. In other words, if there is ever a discrepancy between the items table and the MARC XML, the items table should be considered accurate. =head1 HISTORICAL NOTE Most of the functions in C were originally in the C module. =head1 CORE EXPORTED FUNCTIONS The following functions are meant for use by users of C =cut =head2 GetItem $item = GetItem($itemnumber,$barcode,$serial); Return item information, for a given itemnumber or barcode. The return value is a hashref mapping item column names to values. If C<$serial> is true, include serial publication data. =cut sub GetItem { my ($itemnumber,$barcode, $serial) = @_; my $dbh = C4::Context->dbh; my $data; if ($itemnumber) { my $sth = $dbh->prepare(" SELECT * FROM items WHERE itemnumber = ?"); $sth->execute($itemnumber); $data = $sth->fetchrow_hashref; } else { my $sth = $dbh->prepare(" SELECT * FROM items WHERE barcode = ?" ); $sth->execute($barcode); $data = $sth->fetchrow_hashref; } return unless ( $data ); if ( $serial) { my $ssth = $dbh->prepare("SELECT serialseq,publisheddate from serialitems left join serial on serialitems.serialid=serial.serialid where serialitems.itemnumber=?"); $ssth->execute($data->{'itemnumber'}) ; ($data->{'serialseq'} , $data->{'publisheddate'}) = $ssth->fetchrow_array(); } #if we don't have an items.itype, use biblioitems.itemtype. if( ! $data->{'itype'} ) { my $sth = $dbh->prepare("SELECT itemtype FROM biblioitems WHERE biblionumber = ?"); $sth->execute($data->{'biblionumber'}); ($data->{'itype'}) = $sth->fetchrow_array; } return $data; } # sub GetItem =head2 CartToShelf CartToShelf($itemnumber); Set the current shelving location of the item record to its stored permanent shelving location. This is primarily used to indicate when an item whose current location is a special processing ('PROC') or shelving cart ('CART') location is back in the stacks. =cut sub CartToShelf { my ( $itemnumber ) = @_; unless ( $itemnumber ) { croak "FAILED CartToShelf() - no itemnumber supplied"; } my $item = GetItem($itemnumber); if ( $item->{location} eq 'CART' ) { $item->{location} = $item->{permanent_location}; ModItem($item, undef, $itemnumber); } } =head2 ShelfToCart ShelfToCart($itemnumber); Set the current shelving location of the item to shelving cart ('CART'). =cut sub ShelfToCart { my ( $itemnumber ) = @_; unless ( $itemnumber ) { croak "FAILED ShelfToCart() - no itemnumber supplied"; } my $item = GetItem($itemnumber); $item->{'location'} = 'CART'; ModItem($item, undef, $itemnumber); } =head2 AddItemFromMarc my ($biblionumber, $biblioitemnumber, $itemnumber) = AddItemFromMarc($source_item_marc, $biblionumber); Given a MARC::Record object containing an embedded item record and a biblionumber, create a new item record. =cut sub AddItemFromMarc { my ( $source_item_marc, $biblionumber ) = @_; my $dbh = C4::Context->dbh; # parse item hash from MARC my $frameworkcode = GetFrameworkCode( $biblionumber ); my ($itemtag,$itemsubfield)=GetMarcFromKohaField("items.itemnumber",$frameworkcode); my $localitemmarc=MARC::Record->new; $localitemmarc->append_fields($source_item_marc->field($itemtag)); my $item = &TransformMarcToKoha( $dbh, $localitemmarc, $frameworkcode ,'items'); my $unlinked_item_subfields = _get_unlinked_item_subfields($localitemmarc, $frameworkcode); return AddItem($item, $biblionumber, $dbh, $frameworkcode, $unlinked_item_subfields); } =head2 AddItem my ($biblionumber, $biblioitemnumber, $itemnumber) = AddItem($item, $biblionumber[, $dbh, $frameworkcode, $unlinked_item_subfields]); Given a hash containing item column names as keys, create a new Koha item record. The first two optional parameters (C<$dbh> and C<$frameworkcode>) do not need to be supplied for general use; they exist simply to allow them to be picked up from AddItemFromMarc. The final optional parameter, C<$unlinked_item_subfields>, contains an arrayref containing subfields present in the original MARC representation of the item (e.g., from the item editor) that are not mapped to C columns directly but should instead be stored in C and included in the biblio items tag for display and indexing. =cut sub AddItem { my $item = shift; my $biblionumber = shift; my $dbh = @_ ? shift : C4::Context->dbh; my $frameworkcode = @_ ? shift : GetFrameworkCode( $biblionumber ); my $unlinked_item_subfields; if (@_) { $unlinked_item_subfields = shift }; # needs old biblionumber and biblioitemnumber $item->{'biblionumber'} = $biblionumber; my $sth = $dbh->prepare("SELECT biblioitemnumber FROM biblioitems WHERE biblionumber=?"); $sth->execute( $item->{'biblionumber'} ); ($item->{'biblioitemnumber'}) = $sth->fetchrow; _set_defaults_for_add($item); _set_derived_columns_for_add($item); $item->{'more_subfields_xml'} = _get_unlinked_subfields_xml($unlinked_item_subfields); # FIXME - checks here unless ( $item->{itype} ) { # default to biblioitem.itemtype if no itype my $itype_sth = $dbh->prepare("SELECT itemtype FROM biblioitems WHERE biblionumber = ?"); $itype_sth->execute( $item->{'biblionumber'} ); ( $item->{'itype'} ) = $itype_sth->fetchrow_array; } my ( $itemnumber, $error ) = _koha_new_item( $item, $item->{barcode} ); $item->{'itemnumber'} = $itemnumber; ModZebra( $item->{biblionumber}, "specialUpdate", "biblioserver" ); logaction("CATALOGUING", "ADD", $itemnumber, "item") if C4::Context->preference("CataloguingLog"); return ($item->{biblionumber}, $item->{biblioitemnumber}, $itemnumber); } =head2 AddItemBatchFromMarc ($itemnumber_ref, $error_ref) = AddItemBatchFromMarc($record, $biblionumber, $biblioitemnumber, $frameworkcode); Efficiently create item records from a MARC biblio record with embedded item fields. This routine is suitable for batch jobs. This API assumes that the bib record has already been saved to the C and C tables. It does not expect that C and C are populated, but it will do so via a call to ModBibiloMarc. The goal of this API is to have a similar effect to using AddBiblio and AddItems in succession, but without inefficient repeated parsing of the MARC XML bib record. This function returns an arrayref of new itemsnumbers and an arrayref of item errors encountered during the processing. Each entry in the errors list is a hashref containing the following keys: =over =item item_sequence Sequence number of original item tag in the MARC record. =item item_barcode Item barcode, provide to assist in the construction of useful error messages. =item error_code Code representing the error condition. Can be 'duplicate_barcode', 'invalid_homebranch', or 'invalid_holdingbranch'. =item error_information Additional information appropriate to the error condition. =back =cut sub AddItemBatchFromMarc { my ($record, $biblionumber, $biblioitemnumber, $frameworkcode) = @_; my $error; my @itemnumbers = (); my @errors = (); my $dbh = C4::Context->dbh; # We modify the record, so lets work on a clone so we don't change the # original. $record = $record->clone(); # loop through the item tags and start creating items my @bad_item_fields = (); my ($itemtag, $itemsubfield) = &GetMarcFromKohaField("items.itemnumber",''); my $item_sequence_num = 0; ITEMFIELD: foreach my $item_field ($record->field($itemtag)) { $item_sequence_num++; # we take the item field and stick it into a new # MARC record -- this is required so far because (FIXME) # TransformMarcToKoha requires a MARC::Record, not a MARC::Field # and there is no TransformMarcFieldToKoha my $temp_item_marc = MARC::Record->new(); $temp_item_marc->append_fields($item_field); # add biblionumber and biblioitemnumber my $item = TransformMarcToKoha( $dbh, $temp_item_marc, $frameworkcode, 'items' ); my $unlinked_item_subfields = _get_unlinked_item_subfields($temp_item_marc, $frameworkcode); $item->{'more_subfields_xml'} = _get_unlinked_subfields_xml($unlinked_item_subfields); $item->{'biblionumber'} = $biblionumber; $item->{'biblioitemnumber'} = $biblioitemnumber; # check for duplicate barcode my %item_errors = CheckItemPreSave($item); if (%item_errors) { push @errors, _repack_item_errors($item_sequence_num, $item, \%item_errors); push @bad_item_fields, $item_field; next ITEMFIELD; } _set_defaults_for_add($item); _set_derived_columns_for_add($item); my ( $itemnumber, $error ) = _koha_new_item( $item, $item->{barcode} ); warn $error if $error; push @itemnumbers, $itemnumber; # FIXME not checking error $item->{'itemnumber'} = $itemnumber; logaction("CATALOGUING", "ADD", $itemnumber, "item") if C4::Context->preference("CataloguingLog"); my $new_item_marc = _marc_from_item_hash($item, $frameworkcode, $unlinked_item_subfields); $item_field->replace_with($new_item_marc->field($itemtag)); } # remove any MARC item fields for rejected items foreach my $item_field (@bad_item_fields) { $record->delete_field($item_field); } # update the MARC biblio # $biblionumber = ModBiblioMarc( $record, $biblionumber, $frameworkcode ); return (\@itemnumbers, \@errors); } =head2 ModItemFromMarc ModItemFromMarc($item_marc, $biblionumber, $itemnumber); This function updates an item record based on a supplied C object containing an embedded item field. This API is meant for the use of C; for other purposes, C should be used. This function uses the hash %default_values_for_mod_from_marc, which contains default values for item fields to apply when modifying an item. This is needed beccause if an item field's value is cleared, TransformMarcToKoha does not include the column in the hash that's passed to ModItem, which without use of this hash makes it impossible to clear an item field's value. See bug 2466. Note that only columns that can be directly changed from the cataloging and serials item editors are included in this hash.

The first argument is a hashref mapping from item column names to the new values. The second and third arguments are the biblionumber and itemnumber, respectively. The fourth, optional parameter, C<$unlinked_item_subfields>, contains an arrayref containing subfields present in the original MARC representation of the item (e.g., from the item editor) that are not mapped to C columns directly but should instead be stored in C and included in the biblio items tag for display and indexing.
