I have a method in Categories controller that gets path in catalog of goods
recursively, like that:
function get_path($cat_id, $path = null) {
$path_tmp = $path;
$this->Category->recursive = 0;
$cat = $this->Category->findById($cat_id);
if ($cat['Category']['parent_id'] != 0) {
$cat = $this->Category->findById($cat_id);
$path_tmp[] = $cat;
$this->get_path($cat['Category']['parent_id'], $path_tmp);
}
else {
$cat = $this->Category->findById($cat_id);
$path_tmp[] = $cat;
/*
* PAY ATTENTION HERE!!!
*/
if (isset($this->params['requested']) ){
return $path_tmp;
}
}
}
If I write it this way, I can not get result form function, althouth function
works(but doesn't return result).
And if I modify bottom it in this way:
else {
$cat = $this->Category->findById($cat_id);
$path_tmp[] = $cat;
/*
* I TOOK if ($this->params['requested'] out of last 'else'!!!
*/
}
if (isset($this->params['requested']) ){
return $path_tmp;
}
}
it returns walue, but no recursion can be done this way.
Any help?
