RenRen social network app issues! Getting PHP errors... Any chinese to help? :)
<p>I'm trying to build an app for the Chinese audience at the social networking site RenRen.</p>

<p>Using their PHP API I'm getting these errors:</p>

<blockquote>
  <p>Notice: Undefined index:
  xn_sig_session_key in
  C:\renren_test_app\xiaonei.class.php
  on line 21</p>
  
  <p>Notice: Undefined index: xn_sig_user
  in C:\renren_test_app\header.php on
  line 61</p>
</blockquote>

<p>That's coming from the example PHP app. All I changed in code (at header.php) is the API key/secret.<br>
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.</p>

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

<p><strong>Edit</strong>:<br>
Got the PHP API from: <a href="http://wiki.dev.renren.com/wiki/%25E4%25B8%258B%25E8%25BD%25BD%25E4%25B8%2593%25E5%258C%25BA" rel="nofollow">http://wiki.dev.renren.com/wiki/%25E4%25B8%258B%25E8%25BD%25BD%25E4%25B8%2593%25E5%258C%25BA</a></p>
