An integration of open source social sign on php library HybridAuth into MODX Revolution.

The main goal of HybridAuth library is to act as an abstract api between your application and various social apis and identities providers such as Facebook, Twitter, MySpace, LinkedIn, Google and Yahoo.

HybridAuth enable developers to easily build social applications to engage websites vistors and customers on a social level by implementing social signin, social sharing, users profiles, friends list, activities stream, status updates and more.

In MODX we can log in to site and link our accounts on remote services to one user profile.

Installation¶

1. Register and get api keys from needed services. For example, create twitter application - https://dev.twitter.com/apps/new 2. Open system settings in manager, switch to hybridauth and make\update ha.keys.Servicename. In our example it will be ha.keys.Twitter 3. You need to set your keys as json string with array.

{"key":"your key from twitter","secret":"secret from twitter"}

It is needed for proper initialization of the library ( http://hybridauth.sourceforge.net/userguide/Configuration.html).

4. Now you can run snippet [[!HybridAuth?providers=Twitter]] on any page.

If there are any errors on library initialization - it will be logged in system log.

Known issues¶

Error " You cannot access this page directly" occurs when user session is cached by opcode-cacher, such as php-apc. For example, at MODXCloud this error always occurs.

For solving this, you need to add to the /index.php at the root of site this line for disabling apc caching:

ini_set('apc.cache_by_default', 0);

Otherwise, your session will be cached and snippet will not working properly.
