Rule contrib: Redirect to registration form after user has clicked on Facebook connect

Hold on, that does not work yet...

I give up. I don't understand rules. Code in my rule evaluation var_dumps the return value of my condition as FALSE, but the rules debug log evaluates the condition as true. I can't fight that. Nevermind, sorry for disturbing...

I did not give up... :P

Now, it works as I intended... Here's the rule:

array (
  'rules' => 
  array (
    'rules_redirect_facebook_connect' => 
    array (
      '#type' => 'rule',
      '#set' => 'event_init',
      '#label' => 'Redirect to registration from when user connects to facebook',
      '#active' => 1,
      '#weight' => '0',
      '#categories' => 
      array (
      ),
      '#status' => 'custom',
      '#conditions' =>

        0 =>

        ),
      ),
      '#version' => 6003,
    ),
  ),
)

Just out of curiousity: can someone explain why the two following pieces of code do not have the same result, EVEN :


$urlnew = FALSE !== strpos ( request_uri(), \'?_fb_js_fbu=\' );
$urlnew &= FALSE === strpos ( request_uri(), \'?_fb_js_fbu=0\' );

if( $urlnew ) return true;
else return false;


$urlnew = FALSE !== strpos ( request_uri(), \'?_fb_js_fbu=\' );
$urlnew &= FALSE === strpos ( request_uri(), \'?_fb_js_fbu=0\' );

return $urlnew;

Ok, good point! At the moment, I do need extra information, so there still a use case. But maybe I can use rules and FB connect to retrieve them automatically from Facebook...
