    Hi everybody,

    I'm trying to save data from my custom meta boxes, this can be one meta box, but also multiple. With the following code:

    function image_attachments_init() {
    	if($types = get_option('image_attachments_post_types')) {
        $fields = array();
        foreach ($types as $type)  {
    
          $image_size_name = get_option('image-size-name');
          $image_size_slug = get_option('image-size-slug');
          for($i = 0; $i <= count($image_size_name[$type]); $i++) {
            if($image_size_slug[$type][$i] != '' && $image_size_name[$type][$i] != '') {
              $settings[$image_size_slug[$type][$i]] = $image_size_name[$type][$i];
            }
          }
          //E.G: $settings['test'] => 'test1', $settings['test2'] => 'test2'
          foreach($settings as $slug => $name) {
            $fields[] = $slug;
            add_meta_box($slug, $name, 'image_attachments_setup', $type, 'normal', 'high', array('slug' => $slug, 'name' => $name));
          }
        }
      }
    
      //Must be executed once, right? Not in a loop...
      add_action('save_post','image_attachments_save', 5, 3);
      //Fields is now an array(2) { [0] => 'test1', [1] => 'test2' }, let's send them to image_attachments_save
      do_action_ref_array('save_post', $fields);
    }
    add_action('admin_init','image_attachments_init');

    the 'image_attachments_save' function is the following

    function image_attachments_save($fields) {
      global $post_id;
      echo $post_id;
      $post_id = $post->ID;
      /**
        *
        * The fields are defined in the function image_attachments_init(), so check if it's
        * array(2) { [0] => 'test1', [1] => 'test2' }
        * Ok, here we go, var_dump($fields);
        * Only gives string('test1') and int(788) and this is the post_id.... :confused:.
        * Just want to get array(2) { [0] => 'test1', [1] => 'test2' }
        */
      var_dump(fields);
    	return $post_id;
    }

    If i'm doing a var_dump($fields) in image_attachments_save, i'm not getting the values in my $fields array.
    How can this be done, and how can i get the new post id in the 'image_attachments_save' function.
