Using Arrays as Field Names

[eluser]thomasp[/eluser]
With the fix posted above, default value does not apply when postdata is NULL.
So, a best fix for this issue seem to be :

Code:

function set_value($field = '', $default = '') {
        if (!isset($this->_field_data[$field])) {
            return $default;
        }
        $field = &$this->_field_data[$field]['postdata'];
        if(!isset($field)) {
            return $default;
        }
        else if (is_array($field)) {
            $current = each($field);
            return $current['value'];
        }else {
            return $field;
        }
    }
