Also deals with stocktaking. =head1 FUNCTIONS =head2 barcodedecode =head3 $str = &barcodedecode( barcode => $barcode, [str => $barcode], # synonymn for barcode [filter => $filter], [prefix => $prefix], [itembarcodeprefix => $prefix], # synonymn for prefix [branchcode => $branchcode], ); =over 4 =item Generic filter function for barcode string. Called on every circ if either System Pref B<itemBarcodeInputFilter> or B<itembarcodelength> is set, applying one or both modifications as appropriate. Will do some manipulation of the barcode for systems that deliver a barcode to circulation.pl that differs from the barcode stored for the item. For proper functioning of this filter, calling the function on the correct barcode string (items.barcode) should return an unaltered barcode. Per branch barcode prefixes are inserted AFTER the filter function is applied to fix the barcode at branches.itembarcodelength characters IFF C<C4::Context->preference('itembarcodelength')> exists and is longer than C<length($barcode)>. The optional $filter argument is to allow for testing or explicit behavior that ignores the System Pref. Valid values are the same as the System Pref options. =back =cut # FIXME -- the &decode fcn below should be wrapped into this one. # FIXME -- these plugins should be moved out of Circulation.pm # sub barcodedecode { my %g = @_; $g{barcode} ||= $g{str} || return ''; $g{filter} = C4::Context->preference('itemBarcodeInputFilter') unless $g{filter}; my $filter_dispatch = { 'whitespace' => sub { $g{barcode} =~ s/\s//g; return $g{barcode}; }, 'trim' => sub { $g{barcode} =~ s/^\s+|\s+$//g; return $g{barcode}}, 'T-prefix' => sub { if ($g{barcode} =~ /^[Tt]\D*(\d+)/) { my $t = $1; ($t) = $t =~ /(\d)$/ if length($t) < 7; return sprintf("T%07d", $t); } else { return $g{barcode}; } }, 'cuecat' => sub { chomp($g{barcode}); my @fields = split( /\./, $g{barcode} ); my @results = map( decode($_), @fields[ 1 .. $#fields ] ); if ( $#results == 2 ) { return $results[2]; } else { return $g{barcode}; } }, }; my $filtered = ($g{filter} && exists($filter_dispatch->{$g{filter}})) ? $filter_dispatch->{$g{filter}}() : $g{barcode}; ## handle negative numbers my $testnum = sprintf("%d",$filtered); if (($testnum == $filtered) && $filtered <0) { return $filtered; } ## pull it out for running on commandline, esp. *.t my %userenv = %{C4::Context->userenv || {}}; my $branchcode = $g{branchcode} || $userenv{branch} || '_TEST'; my $bclen = $branchcode eq '_TEST'? length($filtered) : C4::Context->preference('itembarcodelength'); if($bclen && (length($filtered) < $bclen)) { my $prefix = $g{prefix} || $g{itembarcodeprefix} || ''; if ($prefix) { # do nothing } elsif ($branchcode) { $prefix ||= $branchcode eq '_TEST' ? 12345 : GetBranchDetail($branchcode)->{'itembarcodeprefix'}; $prefix ||= ''; } ## relax this #else { # die "No library set and/or no branchcode passed to barcodedecode()"; #} ####### my $padding = C4::Context->preference('itembarcodelength') - length($prefix) - length($filtered); $filtered = $prefix .

C<$barcode> is the barcode of the item to be transferred. If C<$ignore_reserves> is true, C<&transferbook> ignores reserves. Otherwise, if an item is reserved, the transfer fails. Returns three values: =head3 $dotransfer is true if the transfer was successful. =head3 $messages is a reference-to-hash which may have any of the following keys: =over 4 =item C<PendingTransfer> Item already has a pending transfer; cannot do a parallel transfer at the same time. Message returns a hashref of tobranch, frombranch, and datesent. =item C<BadBarcode> There is no item in the catalog with the given barcode. The value is C<$barcode>. =item C<IsPermanent> The item's home branch is permanent. This doesn't prevent the item from being transferred, though. The value is the code of the item's home branch. =item C<DestinationEqualsHolding> The item is already at the branch to which it is being transferred. The transfer is nonetheless considered to have failed. The value should be ignored. =item C<WasReturned> The item was on loan, and C<&transferbook> automatically returned it before transferring it. The value is the borrower number of the patron who had the item. =item C<ResFound> The item was reserved. The value is a reference-to-hash whose keys are fields from the reserves table of the Koha database, and C<biblioitemnumber>. It also has the key C<ResFound>, whose value is either C<Waiting> or C<Reserved>. =item C<WasTransferred> The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored. =back =cut sub transferbook { my ( $tbr, $barcode, $ignoreRs ) = @_; my $messages; my $dotransfer = 1; my $branches = GetBranches(); my $itemnumber = GetItemnumberFromBarcode( $barcode ); my $issue = GetItemIssue($itemnumber); my $biblio = GetBiblioFromItemNumber($itemnumber); # bad barcode.. if ( not $itemnumber ) { $messages->{'BadBarcode'} = $barcode; $dotransfer = 0; } # get branches of book... my $hbr = $biblio->{'homebranch'}; my $fbr = $biblio->{'holdingbranch'}; if ($fbr ~~ $tbr) { $messages->{'SameBranch'} = $tbr; $dotransfer = 0; } # if using Branch Transfer Limits if ( C4::Context->preference("UseBranchTransferLimits") == 1 ) { if ( C4::Context->preference("item-level_itypes") && C4::Context->preference("BranchTransferLimitsType") eq 'itemtype' ) { if ( !
