Total number of Facebook group members

No...the override all depends on the actual web server. Your host probably has it configured to not be user changeable.

However, the problem isn't the include directly. It's how you're including the file. You need to use relative path...not the full directory. The ability to include cross-domain files creates huge security holes in any online development.

Changed the path to this:

<div>
  <?php
  require_once('/home/zardmediagroup/wp-content/themes/romeo_e_giulietta/fb_api/facebook.php');
  $config = array(
    'appId' => 'MYAPPID',
    'secret' => 'MYSECRETID',
    'cookie' => true
  );
  $facebook = new Facebook($config);
  $query = urlencode("SELECT uid FROM group_member WHERE gid = MYGROUPID");
  try {
    $fbData = $facebook->api("/fql?q={$query}");
    echo count($fbData['data']);
  } catch (FacebookApiException $e) {
    echo 'Errore:<br />';
    var_dump($e->getResult());
  };

?>
</div>

But this time I'm having a "Headers already sent" errors:


Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/zardmediagroup/wp-includes/class.wp-scripts.php:65) in /home/zardmediagroup/wp-content/themes/romeo_e_giulietta/fb_api/facebook.php on line 37

All header data must be setup before any output. In this case, you have a <div> starting out. I'm guessing that when creating a new instance of Facebook() that it includes header information. So put that PHP code at the top of your page.

<?php
  require_once('/home/zardmediagroup/wp-content/themes/romeo_e_giulietta/fb_api/facebook.php');
  $config = array(
    'appId' => '350224611710644',
    'secret' => 'a604150d3b8184002d1f04448724d17c',
    'cookie' => true
  );
  $facebook = new Facebook($config);
  $query = urlencode("SELECT uid FROM group_member WHERE gid = 457030854323270");
  try {
    $fbData = $facebook->api("/fql?q={$query}");
    $member_count =  count($fbData['data']);
  } catch (FacebookApiException $e) {};
?>
<div><?php echo $member_count; ?></div>

Ok I see, thx

For some reason this script doesn't return anything (error nor the desired result).... why? I placed the first bit right after the doctype is opened.

[PeejAvery]

Place the PHP code above EVERYTHING else. Then insert the echoing of the $member_count wherever you want it in the page.

[Mad_Griffith]

Still not showing anything...

[PeejAvery]

Are there any PHP errors being outputted? If not, are you using some sort of CSS reset? In that case, you're going to have to style the <div>. Right now, it may just have the text being a size 0 or the same color as the background.

Edit: View the source. I'm sure you'll see that it is there...just stylized to not be visible in HTML/CSS output.

[Mad_Griffith]

mmmh yeah I made a reset stylesheet but DIV are set as display block (the "member count" div as well)
