Ive made this file BassdropMember.php

<?
class BassdropMember extends Member {
   static $db = array(
      "Birthday" => "Date",
   );
   
   function getCMSFields() {
      $fields = parent::getCMSFields();
      $fields->Push(new DateField("Birthday", "Birthday"));
      return $fields;
   }
}
?>

The cms field shows up in the admin form, but theres no field in the database for birthday. I have done a flush and Im sure it said building the date field.

The end result is I put a date in for the members birthday, and it doesnt save....

Have I got it all wrong?

the security-admin doesn't auto-detect different members at the moment, please use this code in _config.php to globally switch to your custom implementation:
Object::useCustomClass('Member','BassdropMember');

if that doesnt help: can you check that the table "BassdropMember" was properly created in your database, with a field "Birthday"?

I've tried to add new fields in Member as described above, but stucked with the problem - newly created users belongs to class Member and so doesn't have new fields in user editing form.
I've resolved this problem by editing MemberTableField.php in cms/code.
(version 2.0.DailyBuild.2007-06-27 and 2.0.1)

in function MemberTableField->addtogroup
replace
$className = $this->stat('data_class');
with
$className = Object::getCustomClass($this->stat('data_class'));

May be this a bug?

test example:

mysite/code/SideMember.php
<?php
class SideMember extends Member {
   static $db = array(
   "PriceLevel" => "Int",
   );
   
   function getCMSFields() {
      $fields = parent::getCMSFields();
      $fields->Push(
         new NumericField("PriceLevel", "PriceLevel")
      );
      return $fields;
   }
}
?>

mysite/_config.php
<?
global $project;
$project = 'mysite';
include(dirname(__FILE__).'/_config_db.php');

Object::useCustomClass('Member','SideMember');
?>

Any hints/doku of your approach to this 'decorating'?
