I can not give the values just by using $link = $enclosure->get_link();. this statement gives me nothing.

~~~~~~~~~~~~~~~
daos/mysql/Items.php:
~~~~~~~~~~~~~~~

public function add($values) {

$en_link = *** enclosures link needed here. but how? ***;

\F3::get('db')->exec('INSERT INTO items (
x,
en_link,
z
) VALUES (
:x,
:en_link,
:z
)',
array(
':x' => $x,
':en_link' => $en_link,
':z' => $z
));
} }

}

selfoss uses SimplePie for fetching the RSS feed. get_enclosure is a function from SimplePie and returns a SimplePie_Enclosure object. This offers following functions:

You have to check whether the enclosure object is available. I'm not sure, but I think some podcast feed just offers a simple link. In this case you don't get any further information without downloading the mp3/video file.

I hope this helps
