105 =head2 getpatroninformation
107 ($borrower, $flags) = &getpatroninformation($env, $borrowernumber, $cardnumber);
109 Looks up a patron and returns information about him or her. If
110 C<$borrowernumber> is true (nonzero), C<&getpatroninformation> looks
111 up the borrower by number; otherwise, it looks up the borrower by card
114 C<$env> is effectively ignored, but should be a reference-to-hash.
116 C<$borrower> is a reference-to-hash whose keys are the fields of the
117 borrowers table in the Koha database. In addition,
118 C<$borrower-E<gt>{flags}> is a hash giving more detailed information
119 about the patron. Its keys act as flags :
121 if $borrower->{flags}->{LOST} {
122 # Patron's card was reported lost
125 Each flag has a C<message> key, giving a human-readable explanation of
126 the flag. If the state of a flag means that the patron should not be
127 allowed to borrow any more books, then it will have a C<noissues> key
130 The possible flags are:
136 Shows the patron's credit or debt, if any.
144 (Gone, no address.) Set if the patron has left without giving a
153 Set if the patron's card has been reported as lost.
161 Set if the patron has been debarred.
169 Any additional notes about the patron.
177 Set if the patron has overdue items. This flag has several keys:
179 C<$flags-E<gt>{ODUES}{itemlist}> is a reference-to-array listing the
180 overdue items. Its elements are references-to-hash, each describing an
181 overdue item. The keys are selected fields from the issues, biblio,
182 biblioitems, and items tables of the Koha database.
184 C<$flags-E<gt>{ODUES}{itemlist}> is a string giving a text listing of
185 the overdue items, one per line.
193 Set if any items that the patron has reserved are available.
195 C<$flags-E<gt>{WAITING}{itemlist}> is a reference-to-array listing the
196 available items. Each element is a reference-to-hash whose keys are
197 fields from the reserves table of the Koha database.

365 ($dotransfer, $messages, $iteminformation) = &transferbook($newbranch, $barcode, $ignore_reserves);
367 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
369 C<$newbranch> is the code for the branch to which the item should be transferred.
371 C<$barcode> is the barcode of the item to be transferred.
373 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
374 Otherwise, if an item is reserved, the transfer fails.
376 Returns three values:
380 is true if the transfer was successful.
384 is a reference-to-hash which may have any of the following keys:
390 There is no item in the catalog with the given barcode. The value is C<$barcode>.
394 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.
396 C<DestinationEqualsHolding>
398 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.
402 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.
406 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>.
410 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.
421 # FIXME - This function tries to do too much, and its API is clumsy.
422 # If it didn't also return books, it could be used to change the home
423 # branch of a book while the book is on loan.

431 # or failure, and set $C4::Circulation::Circ2::errmsg in case of
432 # failure. Or this function could return undef if successful, and an
