Doing a vimeo transient in PHP

functions.php

<?php

#
# ... Other WP functions
#

function vimeo_transient_title($post) {
  if( false === ($value = get_transient('vimeo_title_' . $post->ID) )) {
      $vid_meta = get_post_meta($post->ID,'cmb_vimeo_id_field',true);
      $url = 'http://vimeo.com/api/v2/video/' . $vid_meta . '.php';
      $response = wp_remote_get( $url, array( 'timeout' => 15 ) );
      if ( !is_wp_error( $response ) ) {
          $data = wp_remote_retrieve_body( $response );
      }
      set_transient( 'vimeo_title_' . $post->ID, $data, 60*60*1 );
      $info = unserialize(trim($data));
  } else {
      $info = unserialize(trim($value));
  }

  # Change this if you need something else out of the array
  return $info[0][title];
}


# Example call
# echo vimeo_transient($wp_query->post);

basically if you wanted the vimeo transient title you would call that function above. If you need some other value, you can duplicate the function or break this down even further with more parameters.
