Php 如何在其他帖子中悬停帖子链接时显示包含缩略图和摘录的工具提示

有并没有办法在另一篇wordpress文章中调用缩略图和摘录作为文章的链接？例如，当我在其他帖子中悬停帖子链接时，它会显示包含缩略图、摘录的工具提示。如本网站：

我试过使用插件。 在rb-internal-links.php第114行中 我将此行添加到调用图像：

$image = get_the_post_thumbnail( $post->ID, 'thumbnail' );

但它不起作用

<?php

致以最诚挚的问候。

我不能完全确定我是否理解您的情况。 如果你正在寻找一个插件，让你有html，图像，链接等工具提示

我建议使用工具提示。在这里查找文档和代码：

在阅读了augusto关于使用Tooltipster的建议后，我制作了一个免费的WordPress插件

谢谢你的回答，但我的意思是在wordpress博客上。
