Hi,
I thought I'd ask this here. (see why below)
How do I write afterFind() to modify a field.
For example just something simple like this (just an example):
function afterFind($data) {
foreach ($data as $key => $val) {
if ( isset($val[$this->alias]['name']) ) {
$data[$key][$this->alias]['name2'] = $val[$this->alias]
['name'];
}
}
debug($data);
return $data;
}
What I want to know is how to pick out the field from the passed data
array. There are so many different ways the data is formatted that I
end up with a quite messy series of for's and if's and I still don't
fell 100% sure I got them all. I feel there must be some sure-fire way
to write these.
The Cookbook is not complete compared to what I get.
http://book.cakephp.org/view/681/afterFind
The API does not mention much about this.
I did not find any test in the core that helped me.
I did not find anything on Google that dealt with anything but basic
"primary" data.
I noticed that sometimes afterFind() is called more than once with
different data-structure each time. I asked about that here:

I'd love some clarification of this callback. Thans in advance.
