?>

" onclick="return confirm('确定删除吗');">删除</a>

</td>

<?php

if (isset($_POST['delete-table-submit']) && isset($_GET['id'])) {

$express_id = $_GET['express_id'];

echo esc_html( $express_id );

global $wpdb;

$table_name = $wpdb->prefix . "wp_logistics_express";

$result = $wpdb->delete($table_name, array("express_id" => $express_id));

$home_url='admin.php?page='.$_REQUEST['page'];
