我想创建一个 elementor 小部件并将其添加到基本 elementor 菜单中。我根据本教程找到并执行此操作，但它不起作用（未出现在基本菜单中）：https://develowp.com/build-a-custom-elementor-widget/。 任何人都可以帮我解决这个问题或者任何人都可以正确运行其他代码吗？

Elementor 测试扩展：我用一个短视频制作了一个演示，以演示测试插件及其工作原理。 Github 存储库：https://github.com/robinwpdeveloper/elementor-test-extension-robin
Elementor 文档： 这是来自 elementor 的文档链接，介绍如何创建自己的 elementor 插件（作为插件）：https://developers.elementor.com/docs/getting-started/first-addon/
在您的代码中：确保 test-widget.php 放置在正确的路径中：插件目录 => widgets 文件夹 => test-widget.php （因为您需要这样的文件：
require_once( __DIR__ . '/widgets/test-widget.php' );注意：插件开发手册 - https://developer.wordpress.org/plugins/plugin-basics/header-requirements/
原始代码对我有用。
您的问题可能是因为您的文件路径不正确。 在这种情况下，您必须将其放入子主题中。
我也有同样的问题。可能是你没有激活你的插件。
嗯...我知道已经过去三年了，但改变主题对我来说很有效... :-|
