php - onContentAfterSave トリガーを使用する Joomla Facebook プラグインが機能しない

Question

die('test')関数の最初の行にステートメントを配置して、このトリガーが機能していることを確認しましたonContentAfterSave()。内部の残りのコードが機能しないのはなぜかと思います。

defined('_JEXEC') or die ('Access Deny');

class plgContentMypost extends JPlugin {

    public function onContentAfterSave( $context, $article, $isNew  )
    {
    require_once JPATH_ROOT  . '/plugins/content/mypost/src/facebook.php';

        $appId = '233015226851759';
        $secret = '95daba36aa48679229e';
        $returnurl = 'http://localhost/sample/examples';
        $permissions = 'manage_pages, publish_stream, publish_actions';

        // Create our Application instance (replace this with your appId and secret).
        $fb = new Facebook(array(
          'appId'  => $appId,
          'secret' => $secret,

        ));

        $access_token = $fb->getAccessToken();
        $name = 'LUPIN'; 
        $message = 'this is a message'; 
        $description = 'this is my description';
        $pictureUrl = 'http://rofi.philfire.com.ph/joomla16/images/iphone-4-top-new-1.jpg';
        $link = 'http://rofi.philfire.com.ph/joomla16/'; 

        $attachment =  array(
            'access_token' => $access_token,
            'message' => "$message",
            'name' => "$name",
            'description' => "$description",
            'link' => "$link",
            'picture' => "$pictureUrl",
            // 'actions' => array('name'=>'Try it now', 'link' => "$appUrl")
        );

        $post_id = $fb->api("me/feed","POST",$attachment);

    }

}

このコードをスタンドアロンとして使用すると、問題なく動作し、コンテンツが Facebook に投稿されます。

require_once '/src/facebook.php';

$appId = '233015226851759';
$secret = '95daba36aa48679229e';
$returnurl = 'http://localhost/sample/examples';
$permissions = 'manage_pages, publish_stream, publish_actions';

// Create our Application instance (replace this with your appId and secret).
$fb = new Facebook(array(
    'appId'  => $appId,
    'secret' => $secret,      
));

$access_token = $fb->getAccessToken();
$name = 'LUPIN'; 
$message = 'this is a message'; 
$description = 'this is my description';
$pictureUrl = 'http://rofi.philfire.com.ph/joomla16/images/iphone-4-top-new-1.jpg';
$link = 'http://rofi.philfire.com.ph/joomla16/'; 

$attachment =  array(
    'access_token' => $access_token,
    'message' => "$message",
    'name' => "$name",
    'description' => "$description",
    'link' => "$link",
    'picture' => "$pictureUrl",
    // 'actions' => array('name'=>'Try it now', 'link' => "$appUrl")
);

$post_id = $fb->api("me/feed","POST",$attachment);
