where ... like: non funziona

Prova così:

if ($search !== "") {
        $sql = "SELECT * FROM `feed` WHERE `titolo` LIKE '%$search%' ";
        $result = mysql_query($sql);
        $nr = mysql_num_rows($result);
        if ($nr<0) {
                echo "NO SEARCH VALUE";
            } else {
                echo ">> <a href=\"onefeed.php?feed=" . $row["feed_id"] . "\">" . $row["titolo"] . "</a>
";
            }
}
