希望一切顺利。我编写了一个小部件，它显示来自自定义帖子类型“Staff”的帖子。每当客户添加新员工时，都会显示他们的姓名和特征图像。我的问题是：如何让这些“帖子”填充列？理想情况下，我希望有2行4列。以下是我的小部件代码：

public function widget($args, $instance) {

    //Arguments that you can pass through the widget function. We are displaying only the CPT \'News\' in our widget

    $args = array(
        \'post_type\' => \'Staff\',
        \'posts_per_page\' => -1,
    );

    //Loop through Custom Post Type in there are posts and if we are currently on a single Program page. (\'program\' must be lowercase) EDIT is_singular is now empty to show on all singular pages in general

    $loop = new WP_Query($args);

    if($loop->have_posts() && is_singular(\'\')):
        while($loop->have_posts()) {

            $loop->the_post();

            //What will be displayed physically in the widget for each item

            echo \'<br />\';
            the_title();
            echo \'<div class="entry-content">\';
            the_post_thumbnail(\'thumbnail\');
            the_content();
            echo \'</div>\';


        }endif;


    wp_reset_postdata();
}
