我通过扩展WP\\u widget类，在标准WP文本小部件的基础上创建了一些自定义小部件。我非常希望将小部件的标题强制添加到管理部分侧栏摘要区域的新行。

我在考虑使用一个换行html标记，这样标题就不会被截断或截断。我注意到WordPress向小部件添加了一个span元素。php文件。该文件位于wp admin/includes/widgets中。php。通过在第188行的此处添加换行标记

<div class="widget-title"><h4><?php $widget_title ?><br><span class="in-widget-title">  </span></h4></div>

然而，结果并不令人满意，因为css显然不能适应内容的高度。

问题是，我不确定在哪里放置这样的html标记，以便在下面的实际小部件代码中使更改生效？我可以自己更改wordpress文件，但更新会删除我所做的更改。任何帮助都将不胜感激。

代码随附。
