Quick start

• Sign-on with OpenID is a 2-step process:

  1. Authentication with the provider:

     $openid = new LightOpenID('my-host.example.org');
     
     $openid->identity = 'ID supplied by user';
     
     header('Location: ' . $openid->authUrl());

  2. Verification:

     $openid = new LightOpenID('my-host.example.org');
     
     if ($openid->mode) {
       echo $openid->validate() ? 'Logged in.' : 'Failed!';
     }

• AX and SREG extensions are supported:

  To use the AX and SREG extensions, specify $openid->required and/or $openid->optional before calling $openid->authUrl(). These are arrays, with values being AX schema paths (the 'path' part of the URL). For example:

  $openid->required = array('namePerson/friendly', 'contact/email');
  $openid->optional = array('namePerson/first');

  If the server supports only SREG or OpenID 1.1, these are automaticaly mapped to SREG names.

Identity selector

If you look for an user interface (identity selector) to use with LightOpenID, check out JavaScript OpenID Selector.
