hi quoc,
{n} is a place holder for "index number". CakePHP will automatically
replace it with the appropriate index number. Consider if you have
data in this format and you want to extract all the tiles
// Data
$data = Array([0] =>
array("Post" =>
array('title' => "hello world")
),
[1] =>
array("Post" =>
array('title' => "My First Post")
)
)
//Using Set Class of CakePHP to extract title
Set::extract($data, "{n}.Post.title");
So, as you can see {n} is just a place holder for index number
(0,1,....)
Regards,
bingo
