Using Arrays as Field Names

[eluser]bkirkman[/eluser]
Since the above link is dead, here's the fix that worked for me. I take no credit. It was posted in the bug fix. This is what the set_value function should look like. It can be modified in the Form_validation library, but it is recommended to override it in the custom project library MY_Form_validation. Here goes.

Code:

function set_value($field = '', $default = '')
{
    if ( ! isset($this->_field_data[$field]))
    {
        return $default;
    }

    $field = &$this->_field_data[$field]['postdata'];

    if (is_array($field))
    {
        $current = each($field);
        return $current['value'];
    }

    return $field;
}

Hope this helps.
