当使用wp_insert_post插入新的博客文章时，如何在另一个表中同时添加一条记录？

function insert_post_hook($post_id, $post, $update){
    // 在这里添加代码来插入记录到另一个表中
}
add_action('wp_insert_post', 'insert_post_hook', 10, 3);

function insert_post_hook($post_id, $post, $update){
    global $wpdb;
    
    // 获取新文章的相关信息
    $title = $post->post_title;
    $content = $post->post_content;
    
    // 插入记录到另一个表中
    $table_name = $wpdb->prefix . 'custom_table';
    $wpdb->insert($table_name, array(
        'post_id' => $post_id,
        'title' => $title,
        'content' => $content
    ));
}
add_action('wp_insert_post', 'insert_post_hook', 10, 3);

function create_custom_table(){
    global $wpdb;
    
    // 定义表名和字段
    $table_name = $wpdb->prefix . 'custom_table';
    $charset_collate = $wpdb->get_charset_collate();
    $sql = "CREATE TABLE $table_name (
        id INT NOT NULL AUTO_INCREMENT,
        post_id INT NOT NULL,
        title VARCHAR(255) NOT NULL,
        content TEXT NOT NULL,
        PRIMARY KEY (id)
    ) $charset_collate;";
    
    // 创建表
    require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
    dbDelta($sql);
}
register_activation_hook(__FILE__, 'create_custom_table');
