我正在使用以下小部件检索自定义帖子类型的列表jobs:

class FeaturedJobsWidget extends WP_Widget
{
  function FeaturedJobsWidget()
  {
    $widget_ops = array(\'classname\' => \'FeaturedJobsWidget\', \'description\' => \'Displays a random post with thumbnail\' );
    $this->WP_Widget(\'FeaturedJobsWidget\', \'Featured Jobs\', $widget_ops);
  }

  function form($instance)
  {
    $instance = wp_parse_args( (array) $instance, array( \'title\' => \'\' ) );
    $title = $instance[\'title\'];
?>
  <p><label for="<?php echo $this->get_field_id(\'title\'); ?>">Title: <input class="widefat" id="<?php echo $this->get_field_id(\'title\'); ?>" name="<?php echo $this->get_field_name(\'title\'); ?>" type="text" value="<?php echo attribute_escape($title); ?>" /></label></p>
<?php
  }

  function update($new_instance, $old_instance)
  {
    $instance = $old_instance;
    $instance[\'title\'] = $new_instance[\'title\'];
    return $instance;
  }

  function widget($args, $instance)
  {
    extract($args, EXTR_SKIP);

    echo $before_widget;
    $title = empty($instance[\'title\']) ? \' \' : apply_filters(\'widget_title\', $instance[\'title\']);

    if (!empty($title))
      echo $before_title . $title . $after_title;;

    // WIDGET CODE GOES HERE
    ?>
      <ul class="featured-jobs">
      <?php // Create and run custom loop
        $custom_posts = new WP_Query();
        $custom_posts->query(\'post_type=jobs&posts_per_page=8\');
        while ($custom_posts->have_posts()) : $custom_posts->the_post();
      ?>
        <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
      <?php endwhile; ?>
      <li class="see-all-positions"><a href="http://www.pixelmatic.com/open-jobs/">See All Positions >></a></li>
      </ul>
    <?php

    echo $after_widget;
  }

}

  <?php // Create and run custom loop
    $custom_posts = new WP_Query();
    $custom_posts->query(\'post_type=jobs&posts_per_page=8\');
    while ($custom_posts->have_posts()) : $custom_posts->the_post();
  ?>

有没有其他方法可以在小部件中显示自定义帖子类型的列表？
