Set Value supports Indexes

This is my first item of contribution, so I might need a bit of guidance. This is a replacement for the default set_value() form helper that supports indexes in form elements. The index must be predefined, so my_field[] will not work, however my_field[2] will.

[code] <?php function set_value($field = '', $default = '') { if (FALSE === ($OBJ =& _get_validation_object())) { if(strpos($field, '[') !== false && strpos($field, ']') !== false){ $f = $field; $field = substr($f, 0, strpos($f, '[')); $index = substr($f, strpos($f, '[')+1, (strpos($f, ']')-1) - strpos($f, '[')); } if ( ! isset($_POST[$field])) { return $default; }

    if( is_array($_POST[$field]) && isset($index) && !empty($index)){
        if ( ! isset($_POST[$field][$index]) )
        {
            return $default;
        }
        
        return form_prep($_POST[$field][$index]);
    }

    return form_prep($_POST[$field]);
}

return form_prep($OBJ->set_value($field, $default));

} ?> [/code]
