Answer 1

The query() function returned something that is not an object.

You should always check for errors.

$res = $idconnex->query($req);
if ( ! $res) {
    echo 'This is not an object:
';
    var_dump($res);
    die;
}

You should also always read the manual when you run into problems:

Return Values

PDO::query() returns a PDOStatement object, or FALSE on failure.
