Thank You content very good

Risingson Carlos said...

Thank you so much... In case I didn't said it before, your 9lessons site has been the BASIS of my understanding of Oauth :)

Chris Cagle said...

This is great. have you thought about adding Twitter support into this as well to make it a full suite for social media connection? If you do that, I would surly consider making the purchase.

Mziro said...

It's very useful app , thanks

Damien Norris said...

I hope it works better than the Google Facebook login script you sold earlier

Steve said...

Great job! But you should not work that way to merge or create new accounts. I mean, a lot of people have more than one e-mail address, if the e-mail on Facebook is not the same on the website he's trying to merge the accounts, your script will create a new account for him.

After getting the permission from Facebook, the script should always ask the user what he want to do: merge accounts or create a new account.

Would you mind telling what do you use for making those diagrams? I really like the way they look both clear and sketchy.

Thanks in advance.

Just bought this, can't wait to implement it.

Ken Greenwood said...

Just bought and installed the script. Super easy.

One question - in testing, I added and then removed the app link from my Facebook account. Noticed that there is no logic to update the user table in the database. Would be very useful to have the removal action on the social accounts update the user record in the database to inactive or something... otherwise, any applications will still think the user is associated with their app.

Ken Greenwood said...

Looks like you need to implement the Deauthorize Callback functionality to remove the user from the database (under Advanced settings in FB at least)

Ken Greenwood said...

If figured it out.

if ($found){
$rec->deauth= 1;
//echo "ok";

function parse_signed_request($signed_request, $secret) {
list($encoded_sig, $payload) = explode('.', $signed_request, 2);

// decode the data
$sig = base64_url_decode($encoded_sig);
$data = json_decode(base64_url_decode($payload), true);

if (strtoupper($data['algorithm']) !== 'HMAC-SHA256') {
error_log('Unknown algorithm. Expected HMAC-SHA256');
return null;

// check sig
$expected_sig = hash_hmac('sha256', $payload, $secret, $raw = true);
if ($sig !== $expected_sig) {
error_log('Bad Signed JSON signature!');
return null;

return $data;

function base64_url_decode($input) {
return base64_decode(strtr($input, '-_', '+/'));


Ken Greenwood said...

Last thing - I changed the deauth code to do an update to a new field on the users table called "active". I changed the OuthLogin.php to set that value to 1 when the authorization is occurring and set that value to 0 when the user deauthorizes the app.

That way, you don't lose the users info if you had transactions in your app associated with the user.

How about twitter login.....?

TyYalniz said...

I cannot get the google to work.. I was able to create a client ID and secret for OAuth2 at https://code.google.com/apis/console/ >>> APIs >>> CREDENTIALS .. but when I copy and paste the Client ID and Secret to the google_lib >>> config.php it does not work. b/c I must be missing a step. The written instructions and video instructions seems not so similar and outdated :(

Hostcollate said...

Thanks for the manual! Everything turned out!
