Call to a member function on a non-objec

[nicdp]

The last return line doesn't work... what's wrong with it?

function addNews($db,$titolo,$sommario,$testo,$data_disp,$data_ord,$data_end,$foto_num){
$insert = sprintf("INSERT INTO milanobici_news (titolo,sommario,testo,data_disp,data_ord,data_end,foto_num) VALUES ($titolo,$sommario,$testo,$data_disp,$data_ord,$data_end,$foto_num)");
return $db->query($insert);
}

Judging from the error you at least put in the subjectline (it helps if you tell us what you're doing and what's going wrong) I'd say that $db is not an object.
