It's easy, really - for each of the 3 fields (keyPath, valuePath and
groupPath), instead of passing a string, you can pass an array.
The first entry in the array is the format string, the rest are the
parameters (extracted with Set::extract()).
The format is exactly the same as sprintf() [it calls vsprintf()
internally].
So, passing array('%s %s', '{n}.Person.firstname',
'{n}.Person.surname') as the valuePath does the following:
* realizes it's an array, not a string
* grabs the first entry ('%s %s') for the format, remembers the rest
as parameters
* for each parameter, calls Set::extract($data, ...) :
+ Set::extract($data, '{n}.Person.firstname');
+ Set::extract($data, '{n}.Person.last');
* calls vsprintf($format, $parameters)
You can also use "{1} {2}" as the format string instead of the
sprintf() format, if you like. Personally I prefer the sprintf format,
because I'm more used to it. Plus you can do things like padding,
truncating and whatnot:
Slightly more complicated example:
$data = array(
array('User' => array('id' => 1, 'firstname' => 'Joe', 'surname' =>
'Bloggs')),
array('User' => array('id' => 2, 'firstname' => 'Fred', 'surname' =>
'Bloggs')),
array('User' => array('id' => 3, 'firstname' => 'Jim', 'surname' =>
'Beam')),
array('User' => array('id' => 4, 'firstname' => 'Jack', 'surname' =>
'Daniels')),
);
debug(Set::combine(
$data,
'{n}.User.id',
array('%2$s, %1$.1s.', '{n}.User.firstname', '{n}.User.surname'),
'{n}.User.surname.0'
));
result:
Array
(
[B] => Array
(
[1] => Bloggs, J.
[2] => Bloggs, F.
[3] => Beam, J.
)
[D] => Array
(
[4] => Daniels, J.
)
)
neat, no?
