我使用bootstrap为边栏小部件创建面板，我可以设置小部件的容器标记以及面板标题的标记，但我无法为面板内容提供标记。到目前为止，我有：

register_sidebar(array(
    \'name\' => __(\'Right Sidebar\'),
    \'id\' => \'home_right_1\',
    \'before_widget\' => \'<div class="panel panel-default">\',
    \'after_widget\' => \'</div>\',
    \'before_title\' => \'<div class="panel-heading"><h3 class="panel-title">\',
    \'after_title\' => \'</h3></div>\'
));

引导面板需要如下所示：

<div class="panel panel-default">
  <div class="panel-heading">Panel heading without title</div>
  <div class="panel-body">
    Panel content
  </div>
</div>

如何添加“<；div class=“面板主体”>###</div>；\'到每个小部件？

function my_widget_content_wrap($content) {
    $content = \'<div class="panel-body">\'.$content.\'</div>\';
    return $content;
}
add_filter(\'widget_text\', \'my_widget_content_wrap\');
