Cakephp Hash combine concatenate two fields - cakephp

Question

How can I concatenate two fields inside a select box using cakephp 2.5 and Hash:combine ?
Today I have name:
$banks = Hash::combine($banks, '{n}.Bank.id', '{n}.Bank.name');
I need name and identifier, I tried this:
$banks = Hash::combine($banks, '{n}.Bank.id', '{n}.Bank.name {n}.Bank.identifier');
But it return NULL.
How can I have : name - identifier ?
Also try to concatenate the two fields at the model but could not add an hiffen between name and identifier.

You can provide array’s for both $keyPath and $valuePath. If you do this, the first value will be used as a format string, for values extracted by the other paths:
$result = Hash::combine(
$a,
'{n}.User.id',
array('%s: %s', '{n}.User.Data.user', '{n}.User.Data.name'),
'{n}.User.group_id'
);
/* $result now looks like:
Array
(
[1] => Array
(
[2] => mariano.iglesias: Mariano Iglesias
)
[2] => Array
(
[14] => phpnut: Larry E. Masters
)
)
*/
$result = Hash::combine(
$a,
array('%s: %s', '{n}.User.Data.user', '{n}.User.Data.name'),
'{n}.User.id'
);
/* $result now looks like:
Array
(
[mariano.iglesias: Mariano Iglesias] => 2
[phpnut: Larry E. Masters] => 14
)
*/
