带有嵌套中继器的 Wordpress Elementor 自定义小部件

Question

最终目标是在 Wordpress 中为 Elementor 提供一个小部件，可以在选项卡内创建多个按钮。所以我想要一个中继器内部的中继器。

我还没有所有的功能或样式，只有列出页面上每个输入的非常基本的设置。我的代码不起作用。插件显示正确，但所有元素或控件都消失了。

代码如下：

<?php
namespace Elementor;

if ( ! defined( 'ABSPATH' ) ) {
 exit; // Exit if accessed directly.
}

/**
 * Elementor iatabs widget.
 *
 * Elementor widget that displays vertical or horizontal iatabs with different
 * pieces of content.
 *
 * @since 1.0.0
 */
class Widget_AltTabs extends Widget_Base {

     /**
  * Get widget name.
  *
  * Retrieve iatabs widget name.
  *
  * @since 1.0.0
  * @access public
  *
  * @return string Widget name.
  */
 public function get_name() {
  return 'alttabs';
 }

 /**
  * Get widget title.
  *
  * Retrieve tabs widget title.
  *
  * @since 1.0.0
  * @access public
  *
  * @return string Widget title.
  */
 public function get_title() {
  return __( 'AltTabs', 'elementor' );
 }

 /**
  * Get widget icon.
  *
  * Retrieve tabs widget icon.
  *
  * @since 1.0.0
  * @access public
  *

 public function get_icon() {
  return 'eicon-tabs';
 }

这是我收到的错误消息的示例：

我对编写 Elementor 还很陌生 widget/plugins 所以我在这里被难住了。我将不胜感激任何帮助。谢谢！

转发器控件不支持嵌套转发器

我的解决方案

创建两个中继器并用键绑定它们。祝你好运

protected function _register_controls() {
    $this->start_controls_section(
        'section_categories',
        [
            'label' => __( 'Categories', 'elementor' ),
        ]
    );

    $repeater = new Repeater();

    $repeater->add_control(
        'category_slug',
        [
            'label'       => __( 'Category Slug', 'elementor' ),
            'type'        => Controls_Manager::TEXT,
            'default'     => __( 'category-name', 'elementor' ),
            'label_block' => true,
        ]
    );

    $repeater->add_control(
        'category_title',
        [
            'label'       => __( 'Category Title', 'elementor' ),
            'type'        => Controls_Manager::TEXT,
            'default'     => __( 'Category Title', 'elementor' ),
            'label_block' => true,
        ]
    );

    $this->add_control(
        'categories',
        [
            'label'       => __( 'Contacts', 'elementor' ),
            'type'        => Controls_Manager::REPEATER,
            'fields'      => $repeater->get_controls(),
            'title_field' => '{{{ category_title }}}',
        ]
    );

    $this->end_controls_section();

    $this->start_controls_section(
        'section_prices',
        [
            'label' => __( 'Prices', 'elementor' ),
        ]
    );

    $serviceRepeater = new Repeater();

    $serviceRepeater->add_control(
        'category_slug',
        [
            'label'       => __( 'Category Slug', 'elementor' ),
            'type'        => Controls_Manager::TEXT,
            'default'     => __( 'category-name', 'elementor' ),
            'label_block' => true,
        ]
    );

    $serviceRepeater->add_control(
        'service_title',
        [
            'label'       => __( 'Service Title', 'elementor' ),
            'type'        => Controls_Manager::TEXT,
            'default'     => __( 'Service Title', 'elementor' ),
            'label_block' => true,
        ]
    );

    $serviceRepeater->add_control(
        'service_price',
        [
            'label'       => __( 'Price', 'elementor' ),
            'type'        => Controls_Manager::TEXT,
            'default'     => __( '40,00', 'elementor' ),
            'label_block' => true,
        ]
    );

    $this->add_control(
        'services',
        [
            'label'       => __( 'Services', 'elementor' ),
            'type'        => Controls_Manager::REPEATER,
            'fields'      => $serviceRepeater->get_controls(),
            'title_field' => '{{{ service_title }}}',
        ]
    );

    $this->end_controls_section();
}

添加到渲染

foreach ($settings['categories'] as $category) {
    echo $category['category_title'];

    foreach($settings['services' as $service) {
        if ($category['category_slug'] === $service['category_slug'] {
            echo $category['service_title'];
        }
    }
}
