When I sign in to StackOverflow using Google, I get the following message:

Stackoverflow.com is asking for some information from your Google Account example@gmail.com

• Email address: example@gmail.com

However, on my own site, when I log in with OpenID I can't ask for the e-mail address. Instead, I get this message:

You are signing in to example.com with your Google Account example@gmail.com

I am also finding it difficult to understand at what step I need to request the e-mail address. Here is the code that I think the step should be built into:

/**
 * Authenticates the given OpenId identity.
 * Defined by Zend_Auth_Adapter_Interface.
 *
 * @throws Zend_Auth_Adapter_Exception If answering the authentication query is impossible
 * @return Zend_Auth_Result
 */
public function authenticate() {
    $id = $this->_id;
    $consumer = new Auth_OpenID_Consumer($this->_storage);
    
    if (!empty($id)) {
        $authRequest = $consumer->begin($id);
        
        if (is_null($authRequest)) {
            return new Zend_Auth_Result(
                Zend_Auth_Result::FAILURE,
                $id,
                array("Authentication failed", 'Unknown error')
            );
        }
        
        if (Auth_OpenID::isFailure($authRequest)) {
            return new Zend_Auth_Result(
                Zend_Auth_Result::FAILURE,
                $id,
                array("Authentication failed", "Could not redirect to server: " . $authRequest->message)
            );
        }
        
        $redirectUrl = $authRequest->redirectUrl($this->_root, $this->_returnTo);
        
        if (Auth_OpenID::isFailure($redirectUrl)) {
            return new Zend_Auth_Result(
                Zend_Auth_Result::FAILURE,
                $id,
                array("Authentication failed", $redirectUrl->message)
            );
        }
        
        Zend_OpenId::redirect($redirectUrl);
    } else {
        $response = $consumer->complete(Zend_OpenId::selfUrl());

        switch($response->status) {
            case Auth_OpenID_CANCEL:
            case Auth_OpenID_FAILURE:
                return new Zend_Auth_Result(
                    Zend_Auth_Result::FAILURE,
                    null,
                    array("Authentication failed. " . @$response->message)
                );
                break;
            case Auth_OpenID_SUCCESS:
                return $this->_constructSuccessfulResult($response);
                break;
        }
    }
}

This seems like it should be so obvious... but I'm having a hard time Googling it and combing through the code to figure it out. Any help would be greatly appreciated!

You can ask for an email address using Zend Simple Registration Extension 

$sreg = new Zend_OpenId_Extension_Sreg(array(
    'nickname'=>true,
    'email'=>false,
    'fullname'=>false), null, 1.1);
$consumer = new Zend_OpenId_Consumer();
if (!$consumer->login($_POST['openid_identifier'],
                      'example-6_3.php',
                      null,
                      $sreg)) {
    die("OpenID login failed.");
}

If you want to use Janrain library, you can add extensions to the request like this:

$sreg_request = Auth_OpenID_SRegRequest::build(
                                 // Required
                                 array('nickname'),
                                 // Optional
                                 array('email'));

if ($sreg_request) {
    $authRequest->addExtension($sreg_request);
}

Have a look at the consumer example: https://github.com/openid/php-openid/blob/master/examples/consumer/
