Question

我的“会员”数据库中有3个表，其中包含有关其所属成员名称和团队的信息。我正在尝试构建2个插件。

   One that lists all of my members, with the exception of a "master" member 
   which is a member of all teams. with the ability to bulk add or delete to 
   or from a team.

   The second is a list of all teams, with the ability to bulk add or delete 
   to or from a members profile.

“members”具有成员名称。它还包含一个“主”成员，拥有所有团队的成员资格。它还包含其余成员。

“团队”包含所有团队信息

“members_team”包含成员的ID，并将这些ID连接到与团队关联的ID。每个团队协会一排。

我一直在试验我将在下面添加的现有代码。此时我甚至无法显示表格的内容，更不用说进入批量编辑了。当它与我的编辑一起运行时，我不断得到一个空表或错误。

   if ( ! class_exists( 'WP_List_Table' ) ) {
 require_once( ABSPATH . 'wp-admin/includes/class-wp-list-table.php' );
}

class Members_List extends WP_List_Table {

/** Class constructor */
public function __construct() {

parent::__construct( [
    'singular' => __( 'member', 'sp' ), //singular name of the listed records
    'plural'   => __( 'members', 'sp' ), //plural name of the listed records
    'ajax'     => false //does this table support ajax?
] );

}


/**
 * Retrieve members data from the database
 *
 * @param int $per_page
* @param int $page_number
*
* @return mixed
*/
public static function get_members( $per_page = 5, $page_number = 1 ) {

global $wpdb;

$sql = "SELECT * FROM {$wpdb->prefix}name";

if ( ! empty( $_REQUEST['orderby'] ) ) {
    $sql .= ' ORDER BY ' . esc_sql( $_REQUEST['orderby'] );
    $sql .= ! empty( $_REQUEST['order'] ) ? ' ' . esc_sql( $_REQUEST['order'] ) : ' ASC';
}

$sql .= " LIMIT $per_page";
$sql .= ' OFFSET ' . ( $page_number - 1 ) * $per_page;


$result = $wpdb->get_results( $sql, 'ARRAY_A' );

return $result;

}

使用wp_list_table不列出记录
