Hi trustnoone!

Welcome to SS.

The most simple way to do this is to extend MemberAuthenticator, create a new class such as MyMemberAuthenticator and create a static function called get_login_form that accepts 1 parameter ($controller). then return a new form with the fields you want. They will need to have the same names for the username and password.

You then have to register that authenticator in your _config and unregister the existing one. So in the end you want something like this:


class MyMemberAuthentcator extends MemberAuthenticator {
public static function get_login_form(Controller $controller) {
				$fields = new FieldSet(
					new HiddenField("AuthenticationMethod", null, $this->authenticator_class, $this),
					//Regardless of what the unique identifer field is (usually 'Email'), it will be held in the 'Email' value, below:
					new TextField("Email", $label, Session::get('SessionForms.MemberLoginForm.Email'), null, $this),
					new PasswordField("Password", _t('Member.PASSWORD', 'Password'))
				if(Security::$autologin_enabled) {
					$fields->push(new CheckboxField(
						_t('Member.REMEMBERME', "Remember me next time?")
//push your custom fields in here
$fields->push( ... )
return new MemberLoginForm($controller, 'MemberLoginForm',$fields);



And that should be the ground work done. Validation may be the only problem here, but you can just extend the authenticate method if you need to.

thanks for the reply...

sorry for the late respond. i didn't tried your method yet, yesterday i tried extend MemberLoginForm class. and the functionality is running as i want. when the user tried to login 3 times (wrong login), the MathSpamProtection will show. and the validation i did in dologin function.

i still trying to notice, what is the different with your method...

I found this

If you need only to change the template, you need to put in your templates/Layout folder under your theme
