function _return_type in BF_Model

[cysunshine]

According to the comments "If the type is 'array' or 'json', simply use the array version", but it seems that the return statement does not.

protected function _return_type($multi = false)
{
$method = $multi ? 'result' : 'row';

    // If the type is 'array' or 'json', simply use the array version of the
    // function, since the database library doesn't support json directly.
    return $this->temp_return_type == 'array' ? "{$method}_array" : $method;
}
