 $twitter_title  = get_the_title();

 $twitter_desc   = get_the_excerpt();

   $twitter_thumbs = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), full );

    $twitter_thumb  = $twitter_thumbs[0];

      if(!$twitter_thumb) {

      $twitter_thumb = 'http://share-ask.com/wp-content/uploads/popular-debate-topics-for-high-school-students.jpg';

    }

  $twitter_name   = str_replace('@', '', get_the_author_meta('twitter'));

Where does this function get its data from?

get_the_excerpt();

The description value is appearing empty.

<meta
name="twitter:description" value="" />
