Colin William template library facebook_connect quirk

#1

hi guys,

SORRY FOR THE LONG POST. I JUST WANT TO BE CLEAR!! :cheese:

I am using the stated template library in my ci setup and everything works great except for when i use Mr. Haughin's facebook_connect!
facebook_connect works beautifully if I call anything in a separate view file in my controller like so:

Code:
function facebookconnect()
    {
      $this->load->library('facebook_connect');
        $data = array(
            'user'        => $this->facebook_connect->user,
            'user_id'    => $this->facebook_connect->user_id
            );
      
      
      $this->template->write_view('content','fbtest',$data);
      $this->template->render();
    }
this works no problem calling it from it's own page and everyone is happy. But when I try to put my facebook interactivity into a div on my homepage with this code:

Code:
function index()
    {
        $this->load->library('facebook_connect');
        
        $data = array(
            'user' => $this->facebook_connect->user,
            'user_id' => $this->facebook_connect->user_id
            );
        $this->template->write_view('content','indexpage',$data);
        $this->template->render();
    }
My homepage loads fine but I have this error:
Code:
A PHP Error was encountered

Severity: Notice

Message: Undefined variable: user_id
Filename: views/indexpage.php
Line Number: 32
This i think is strange as it works with code above. My variables are passed so I don't get it.
What I want to achieve is that on the homepage a list of facebook friends should appear when page loads. Is there anything i should know about this library? I went through the userguide looking for to see if i could write a separate view to the div that should carry the facebook connect results. Here is my view code just incase it will help:

Code:
<div class="entry">
<p>
&lt;?php if ( !$user_id ): ?&gt;
<fb:login-button></fb:login-button>
&lt;?php else: ?&gt;
<img class="profile_square" src="&lt;?=$user['pic_square']?&gt;" />
Hi &lt;?=$user['first_name']?&gt;!<br />
<a href="#">(Logout)</a>
&lt;?php endif; ?&gt;
            
    <h2 class="title">Here's some comments!</h2>
    <fb:comments title="Facebook Connect Test" width="520px"></fb:comments>
[removed]
    FB.init("&lt;?=$this->config->item('facebook_api_key')?&gt;", "/xd_receiver.htm");
[removed]
</p>
</div>

just as an update, i changed the index function to look like this:

Code:
function index()
    {
       $this->load->library('facebook_connect');
            
    $data = array(
            'user'        => $this->facebook_connect->user,
            'user_id'    => $this->facebook_connect->user_id
        );
      
    $this->load->vars($data);
    $this->template->write_view('content','indexpage');
        $this->template->render();
    }

This eliminates the error on my homepage, but nothing from facebook comes through! will still look further into this, any ideas are welcome.

Remove those short tag php code from the view file, so change &lt;?= to be &lt;?php echo
