我正在尝试在可视化作曲中创建一个自定义元素，用于在单个页面中显示5个帖子，并在接下来的5个页面中使用分页等等 . 这是自定义元素创建的代码 .

class vc_show_post_list extends WPBakeryShortCode
    {  

function __construct() {


    add_action('init', array($this, 'show_post_list_mapping'));
    add_shortcode('vc_show_post_list', array($this, 'vc_show_post_list_callback'));
}
public function show_post_list_mapping() {
    if (!defined('WPB_VC_VERSION')) {
        return;
    }

    vc_map(
        array(
            'name' => __('Show posts list', 'text-domain'),
            'base' => 'vc_show_post_list',
            'description' => __('VC Element For showing posts', 'text-domain'),
            'category' => __('Custom VC Elements for Showing post list', 'text-domain'),
            'params' => array(
                array(
                    'type' => 'textfield',
                    "holder" => "div",
                    "class" => "",
                    "heading" => __("Post count", "my-text-domain"),
                    'param_name' => 'show_post_list_count',
                    'description' => __('Enter No of post to be shown in a page', 'js_composer'),
                    )
                )
            )
        );
}

在前端已经使用此代码来显示帖子的数量

public function vc_show_post_list_callback($atts, $content = null) 
     {
    global $post;

    $atts = extract(
        shortcode_atts(
            array(
                'show_post_list_count' => '',
                ), $atts
            )
        );

    $html = '';
    $post_list = '';
    $paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
    $args = array(
        'post_type' => 'post',
        'numberposts' => $show_post_list_count,
        'paged'          => $paged
        );
    $myposts = get_posts($args);
    $post_date=get_the_date('j.F Y');
    foreach ($myposts as $post) : setup_postdata($post);
    $post_list .= '<div class="col-md-12 border-mark">
    <div class="col-md-4">
        <img src="'.get_the_post_thumbnail_url($post->ID).'"/>
    </div>
    <div class="col-md-8">
        <h3>'.$post->post_title.'</h3>
        <span>'.$post_date.'</span>
        <p>'.$post->post_excerpt.'</p>
        <a href="'.get_post_permalink($post->ID).'">Read More</a>
    </div>
</div>';
$paginate_links ='<div class="pagination">
'.get_the_posts_pagination( array(
  'mid_size' => 2,
  'prev_text' => __( 'Newer', 'textdomain' ),
  'next_text' => __( 'Older', 'textdomain' ),
  ) ).'
 </div>';
endforeach; 
wp_reset_postdata();


 $html = '<div class="post-list">'.$post_list.'</div>
 <div class="paginations">'.$paginate_links.'</div>';
 return $html;

 }

 }

 new vc_show_post_list();

但只有分页没有显示帖子 . 任何想法我做错了什么？先感谢您
