How to fetch account data from a provider with LightOpenID?

Question

I'm having problems with a small OpenID-library called LightOpenID . I can authenticate to almost all providers, but I don't know how to fetch the data from the provider. I only get Array(), even with print_r().

We need more information... how about telling us exactly what you've tried (as in, copy and paste your code) and then tell us the results (as in, copy and paste). – Leverrier

Sorry, here is the code: pastebin.com/kS9S4WVk Everything works pretty well, but on line 39-41 I try to print the email of the current account. The result is "Array()". – Propolis

Is error reporting / display errors on? Have you checked your PHP error log? – Leverrier

Answer 1

You need to call getAttributes() after $openid->validate() not before.

Remember:

Note that it does not guarantee that any of the required/optional parameters will be present

I've done like this now: pastebin.com/ULsLvhxp So to display the email, do I use $foo['email']? – Propolis

It'll be $foo['contact/email'] - as per the docs, the attributes are mapped to the AX format. – Bagasse

Also, $openid->required = array('contact/email'); needs to be called before $openid->validate() – Bagasse

pastebin.com/Xrhh7Ukb - Still not working, I'm pretty sure it should show some nickname or email. – Propolis

You've got $openid->validate(); twice. Also, as mentioned, there's no guarantee that the OP or user exchanges the information. – Bagasse

Answer 2

This is how I use it. This is the file openid.php in the folder lightopenid. In the class make the following additional functions -

class LightOpenID
{
    public $returnUrl
         , $required = array()
         , $optional = array()
         , $verify_peer = null
         , $capath = null
         , $cainfo = null;

    // these are the variables which store the data about the user...
    public function ret_fname() { return $this->data['openid_ext1_value_namePerson_first']; }
    public function ret_lname() { return $this->data['openid_ext1_value_namePerson_last']; }
    public function ret_email() { return $this->data['openid_ext1_value_contact_email']; }
    public function ret_lang() { return $this->data['openid_ext1_value_pref_language']; }
}

Now make your file example login.php which is called when you want to authenticate. There might be several copies of this file for different authentication domains etc.

<?php
# Logging in with Google accounts requires setting special identity, so this example shows how to do it.
session_start();
require 'lightopenid/openid.php';
include_once('config.php');                // initial setting file

try {

    $openid = new LightOpenID;                            // akshat - declared an object of class lightopenid.. this is listed in openid.php
    if(!$openid->mode) {

        if(isset($_GET['login'])) {

            $openid->identity = 'https://www.google.com/accounts/o8/site-xrds?hd=YourDomain.in'; //this can be changed as you know...       

            $openid->required = array('namePerson/friendly', 'contact/email' , 'contact/country/home', 'namePerson/first', 'pref/language', 'namePerson/last'); // akshat - line added by me from after reading from the net....

            header('Location: ' . $openid->authUrl());    
        }
?>
<script type="text/javascript" src="js/jquery-1.4.2.min.js" language="javascript"></script>
<script type="text/javascript">
    $(document).ready(function() {
            document.form.submit();
    });

</script>
<form name="form" action="?login" method="post"> </form>
<?php
    } elseif($openid->mode == 'cancel') {
        echo 'User has canceled authentication for Your Domain !';
    } else {                                                // FETCH USER INFO HERE
                $fname = $openid->ret_fname();              // fetching user first name...
        $lname = $openid->ret_lname();                  // fetching user last name...
        $email = $openid->ret_email();                  // fetching user email...
        $lang = $openid->ret_lang();                    // fetching user language...
                session_start();

                // use it as required. I set them in session !
                $_SESSION['admin']['emailID'] = $email;          //put email id in session.
                $_SESSION['admin']['fname'] = $fname;            //put first name also in session.
                $_SESSION['admin']['lname'] = $lname;            //put last name also in session.
                $rurl = $_SESSION['redirect'];                   // you can ignore this. Go to your own page now...
                header("Location:$rurl");               // Go back to the calling application !

    }
} catch(ErrorException $e) {
    echo $e->getMessage();
}
?>
