Wordpress 嵌套项-可视化编写器

我尝试为VisualComposer versrion 5.2创建新的小部件

我找到了这个

因此，我创建了一些示例小部件：

    <?php
/*
Plugin Name: Example nested item
Plugin URI: http://wpbakery.com/vc
Description:
Version: 0.1.1
Author: PG
License: GPLv2 or later
*/


// don't load directly
if (!defined('ABSPATH')) die('-1');

class ExampleNested {

    public function __construct()
    {
        // We safely integrate with VC with this hook
        add_action('vc_before_init', [$this, 'initVC']);

        // Use this when creating a shortcode addon
        add_shortcode('your_gallery', [$this, 'renderGallery']);
        add_shortcode('single_img', [$this, 'renderSingleImg']);
    }

    public function renderGallery()
    {
        /**
         *
         */
    }

    public function renderSingleImg()
    {
        /**
         *
         */
    }

    public function initVC() {
        vc_map( array(
            "name" => __("Your Gallery", "my-text-domain"),
            "base" => "your_gallery",
            "as_parent" => array('only' => 'single_img'), // Use only|except attributes to limit child shortcodes (separate multiple values with comma)
            "content_element" => true,
            "show_settings_on_create" => false,
            "is_container" => true,
            "params" => array(
                // add params same as with any other content element
                array(
                    "type" => "textfield",
                    "heading" => __("Extra class name", "my-text-domain"),
                    "param_name" => "el_class",
                    "description" => __("If you wish to style particular content element differently, then use this field to add a class name and then refer to it in your css file.", "my-text-domain")
                )
            ),
            "js_view" => 'VcColumnView'
        ) );
        vc_map( array(
            "name" => __("Gallery Image", "my-text-domain"),
            "base" => "single_img",
            "content_element" => true,
            "as_child" => array('only' => 'your_gallery'), // Use only|except attributes to limit parent (separate multiple values with comma)
            "params" => array(
                // add params same as with any other content element
                array(
                    "type" => "textfield",
                    "heading" => __("Extra class name", "my-text-domain"),

                    "description" => __("If you wish to style particular content element differently, then use this field to add a class name and then refer to it in your css file.", "my-text-domain")
                )
            )
        ) );
    }
}

new ExampleNested();

//Your "container" content element should extend WPBakeryShortCodesContainer class to inherit all required functionality
if ( class_exists( 'WPBakeryShortCodesContainer' ) ) {
    class WPBakeryShortCode_Your_Gallery extends WPBakeryShortCodesContainer {
    }
}
if ( class_exists( 'WPBakeryShortCode' ) ) {
    class WPBakeryShortCode_Single_Img extends WPBakeryShortCode {
    }
}
