WordPress自定义表单在管理面板上提交数据视图？

我在网站上创建了一个自定义表单, 其中包含2个字段和一个提交按钮。

看一下我的表格：

<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> 

站点访问者提交表单时, 我想将提交的数据显示到我的WordPress管理面板上, 以便我可以分别删除它们。

我想这样：

那么, 没有任何插件怎么办呢？

你需要使用” WP_List_Table”类

<?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 {

        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 );

    }
