【问题描述】：
我在 WordPress 中创建了这个 PHP 代码来将图像添加到菜单中，但是它复制了一个 div，其中有一个添加按钮，我不知道为什么，我需要它只是一个而不是两个结果div，以防我只想要左边的 div……我会添加一张关于我在说什么的图片，这样你就可以分析我的问题了！
结构放置在函数wp_post_thumbnail_only_html内
我只留下了传递按钮的动作以方便。

-
你能提供所有的代码吗？你放在这里的只是它的一部分
-
代码很多，但我还是更新了问题...谢谢
-
能分享一下生成的HTML的相关部分吗？另外，您确定这是 PHP 问题而不是 JavaScript 问题吗？到目前为止，你做了什么来调试这个？你能确认一下
wp_post_thumbnail_html被调用了多少次，每次调用的参数值（$item_id）是多少？ -
@WOUNDEDStevenJones 所有代码都已匹配，什么都不做，并且在代码中调用按钮
<? php echo $this->wp_post_thumbnail_html($content);?>在 js 我只调用功能，除非是因为没有 Ajax 的 html -
从外观上看，这个函数正在输出类似
<p>image<br><a><img /></a></p>的东西。但是您的示例还包括上面的单词Menu，这似乎不在您的PHP代码中。那么<? php echo $this->wp_post_thumbnail_html($content);?>是否有可能从您的模板中被调用两次？请包含调用此函数的相关模板代码。
