Looks like the first problem is this line:
$rss = $this->set('news', $this->GoogleNews->find('all'));
You're setting the $rss variable to the return value of the $this->set method.
Checking the documentation for Controller::set...
http://book.cakephp.org/view/427/set
...nowhere does this suggest that $this->set provides a return value (and
looking at the source code in cake/libs/controller/controller.php confirms it
does not return anything). So it's no surprise your foreach loop complains when
trying to iterate over an empty variable.
It seems like you should instead write:
// Get the data from Google News
$newsItems = $this->GoogleNews->find('all');
// Put the news items into the view
$this->set('news', $newsItems);
// Do other things with the news items
foreach ($newsItems as $newsItem) {
...
}
I renamed $rss to $newsItems since $rss isn't the raw RSS XML data (which is
what I thought you were talking about initially) but simply an array of values,
much as you would get from any other data source. If I were retrieving news
items from a database, I wouldn't call the variable $db either.
