Retrieve an arrayref of extended attributes associated with the
|
|
patron specified by C<$borrowernumber>. Each entry in the arrayref
|
|
is a hashref containing the following keys:
|
|
|
|
code (attribute type code)
|
|
description (attribute type description)
|
|
value (attribute value)
|
|
value_description (attribute value description (if associated with an authorised value))
|
|
password (password, if any, associated with attribute
|
|
|
|
If the C<$opac_only> parameter is present and has a true value, only the attributes
|
|
marked for OPAC display are returned.

Given an attribute type and value, verify if would violate

a unique_id restriction if added to the patron. The

optional C<$borrowernumber> is the patron that the attribute

value would be added to, if known.

Returns false if the C<$code> is not valid or the

value would violate the uniqueness constraint.

Takes three arguments. The first two are references to array of hashrefs, each like:

|
[ { code => 'CODE', value => 'value' }, { code => 'CODE2', value => 'othervalue' } ... ]

The third option specifies whether repeatable codes are clobbered or collected. True for non-clobber.

Returns one reference to (merged) array of hashref.
