元素或致命错误:找不到类'Elementor\Widget_Base‘

Question

我试图在Elementor中创建基本的小部件。在遵循开发人员文档创建新小部件时，将引发以下错误：

致命错误:找不到类“Elementor\Widget_Base”

这是我的代码(大部分是从官方文档中复制的)

Answer 1

我也有同样的问题。取$this->include()；退出init方法，并将其放入register_widgets方法中：

public function init() {

   ...

   // Include plugin files
   // $this->includes(); // <-- remove this

}

public function register_widgets() {

    $this->includes(); // <- put it here
    \Elementor\Plugin::instance()->widgets_manager->register_widget_type( new \Elementor_oEmbed_Widget() );

}
