Extending the Login Form




Community Member, 101 Posts

the default LoginForm has two(2) text fileds

1. EMAIL ...................................
2. PASSWORD ..................................

Now i want to extend this by adding one or two more text fields basically for the sake of validation. eg like adding a third field for Recapture since the form will be on every page of the site.

after login user have to be redirected to their respective page with relevant content.

i am using CustomeLogin form and the here is the code


class CustomLogin extends MemberLoginForm {

   // this function is overloaded on our sublcass (this) to do something different
   public function dologin($data) {
      if($this->performLogin($data)) {
            //echo 'done';
      } else {
         if($badLoginURL = Session::get("BadLoginURL")) {
         } else {

   public function redirectByGroup($data) {    

      // gets the current member that is logging in.
      $member = Member::currentUser();
      // gets all the groups.
      $Groups = DataObject::get("Group");
      //cycle through each group   
      foreach($Groups as $Group){
         //if the member is in the group and that group has GoToAdmin checked
         if($member->inGroup($Group->ID) && $Group->GoToAdmin == 1)
            //redirect to the admin page
             Director::redirect(Director::baseURL() . 'admin' );
            return true;
         //otherwise if the member is in the group and that group has a page link defined
         elseif($member->inGroup($Group->ID) && $Group->LinkPageID != 0)
            //Get the page that is referenced in the group      
            $Link = DataObject::get_by_id("SiteTree", "{$Group->LinkPageID}")->URLSegment;
            //direct to that page
            Director::redirect(Director::baseURL() . $Link);
            return true;
      //otherwise if none of the above worked return false
      return false;

_congif.php i add these lines

Object::useCustomClass('MemberLoginForm', 'CustomLogin');

//Tells silverstripe to add our extention to the group class
Object::add_extension('Group', 'GroupDecorator');

in the CMS i just create more Groups and specify which pages they go after log in.

The above code is work but it is limited to what i want.
