$borrower = &getmember($cardnumber, $borrowernumber);
|
|
|
|
Looks up information about a patron (borrower) by either card number
|
|
or borrower number. If $borrowernumber is specified, C<&borrdata>
|
|
searches by borrower number; otherwise, it searches by card number.
|
|
|
|
C<&getmember> returns a reference-to-hash whose keys are the fields of
|
|
the C<borrowers> table in the Koha database.
