no way to do that in PHP, afaik. the { } string operators will not
operate on a function.
However if you add something like this to your app_controller;
[code]
function get($data, $member) {
if (!is_array($member)) {
$member = explode('.', $member);
}
foreach($member as $m) {
if (isset($data[$m])) {
$data = $data[$m];
} else {
trigger_error("Oups! There is no '$m' defined!
(req:
'".implode('.',$member)."')",E_USER_NOTICE);
break;
}
}
return $data;
}
[/code]
You'll be able to do something like this;
$foo = $this->get($this->User->findbyId('3'),'User.name');
and.. for efficiency's sake, you could do something like this instead;
extracts only the username... instead of the whole user obj...
$foo = $this->get($this->User-
>findbyId('3',array('name')),'User.name');
Hope this helps!
