Ben sosyal ağ sitesi RenRen de Çinli izleyici için bir uygulama oluşturmak çalışıyorum.

Ben bu hataları alıyorum kendi PHP API kullanarak:

Notice: Undefined index: xn_sig_session_key in C:\renren_test_app\xiaonei.class.php on line 21

Notice: Undefined index: xn_sig_user in C:\renren_test_app\header.php on line 61

That's coming from the example PHP app. All I changed in code (at header.php) is the API key/secret.
I'd like to know how to fix this as this looks very fundamental.............. and if someone willing to be more helpful - how do I get; User's name/pic/id.

I do not understand Chinese at all so it makes things a lot harder on me. I'd appriciate if someone posts some code!
I hope someone smarter than me can help here (:

Edit:
Got the PHP API from: http://wiki.dev.renren.com/wiki/%25E4%25B8%258B%25E8%25BD%25BD%25E4%25B8%2593%25E5%258C%25BA
