Пользовательская форма WordPress для представления данных на панели администратора?

Question

Я создал пользовательскую форму на своем сайте с двумя полями и кнопкой отправки.
Посмотрите на мою форму:

<div class="control-group"> 
    <label class="control-label" for="name">Name</label> 
    <div class="controls"> 
    <input type="text" name="name" placeholder="Your Name" class="form-control"> 
    </div> 
</div> 
<div class="control-group"> 
    <label class="control-label" for="number">Mobile</label> 
    <div class="controls"> 
    <input type="number" name="number" placeholder="017xxxxxxxx" class="form-control"> 
    </div> 
</div> 
<button type="submit" value="sub" name="sub" class="btn btn-success btn-block btn-sm marTop15">Submit!</button> 

Когда посетитель сайта отправить форму, я хочу, чтобы отобразить данные, представленные на мой WordPress панели администратора, так что я могу удалить их по отдельности.

Я хочу сделать так:

Так как я могу сделать это без каких-либо плагинов?

Вы должны использовать «WP_List_Table» класса

<?php 

if(!class_exists('WP_List_Table')) { 

    require_once(ABSPATH . 'wp-admin/includes/class-wp-list-table.php'); 

} 



class TT_Orders_List_Table extends WP_List_Table { 

    function __construct() { 

     parent::__construct(array(

      'singular' => 'ID', 

      'plural' => 'ID', 

      'ajax'  => false 

     )); 

    } 



    function column_default($item, $column_name) { 

     switch($column_name) { 

      case 'user_firstname': 

      case 'user_login': 

      case 'user_email': 

      case 'paid_charge': 

      case 'additional_member': 

      case 'date': 

       return $item->$column_name; 

      default: 

       return print_r($item,true); //Show the whole array for troubleshooting purposes 

     } 

    } 

    function column_user_firstname($item) { 
     $actions = array(
      'delete' => sprintf('<a href="users.php?page=%s&action=delete&id=%s&wp_http_referer=%s">Delete</a>', $_REQUEST['page'], $item->id, 'wp-admin/users.php?page='.$_REQUEST['page']), 
     ); 

     return sprintf('%1$s <span style="color:silver">(ID:%2$s)</span>%3$s', /*$1%s*/ $item->user_firstname, /*$2%s*/ $item->id, /*$3%s*/ $this->row_actions($actions)); 

    } 



    function column_cb($item) { 

     return sprintf('<input type="checkbox" name="%1$s[]" value="%2$s" />', /*$1%s*/ $this->_args['singular'], $item->ID); 

    }
