145 ($borrower, $flags) = &getpatroninformation($env, $borrowernumber, $cardnumber);
147 Looks up a patron and returns information about him or her. If
148 C<$borrowernumber> is true (nonzero), C<&getpatroninformation> looks
149 up the borrower by number; otherwise, it looks up the borrower by card
152 C<$env> is effectively ignored, but should be a reference-to-hash.
154 C<$borrower> is a reference-to-hash whose keys are the fields of the
155 borrowers table in the Koha database. In addition,
156 C<$borrower-E<gt>{flags}> is a hash giving more detailed information
157 about the patron. Its keys act as flags :
159 if $borrower->{flags}->{LOST} {
160 # Patron's card was reported lost
163 Each flag has a C<message> key, giving a human-readable explanation of
164 the flag. If the state of a flag means that the patron should not be
165 allowed to borrow any more books, then it will have a C<noissues> key
168 The possible flags are:
174 Shows the patron's credit or debt, if any.
182 (Gone, no address.) Set if the patron has left without giving a
191 Set if the patron's card has been reported as lost.
199 Set if the patron has been debarred.
207 Any additional notes about the patron.
215 Set if the patron has overdue items. This flag has several keys:
217 C<$flags-E<gt>{ODUES}{itemlist}> is a reference-to-array listing the
218 overdue items. Its elements are references-to-hash, each describing an
219 overdue item. The keys are selected fields from the issues, biblio,
220 biblioitems, and items tables of the Koha database.
222 C<$flags-E<gt>{ODUES}{itemlist}> is a string giving a text listing of
223 the overdue items, one per line.
231 Set if any items that the patron has reserved are available.
233 C<$flags-E<gt>{WAITING}{itemlist}> is a reference-to-array listing the
234 available items. Each element is a reference-to-hash whose keys are
235 fields from the reserves table of the Koha database.

403 ($dotransfer, $messages, $iteminformation) = &transferbook($newbranch, $barcode, $ignore_reserves);
405 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
407 C<$newbranch> is the code for the branch to which the item should be transferred.
409 C<$barcode> is the barcode of the item to be transferred.
411 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
412 Otherwise, if an item is reserved, the transfer fails.
414 Returns three values:
418 is true if the transfer was successful.
422 is a reference-to-hash which may have any of the following keys:
428 There is no item in the catalog with the given barcode. The value is C<$barcode>.
432 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.
434 C<DestinationEqualsHolding>
436 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.
440 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.
444 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>.
448 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.
459 # FIXME - This function tries to do too much, and its API is clumsy.
460 # If it didn't also return books, it could be used to change the home
