thinkphp5 数据库查询之paginate: 同时获取记录总数和分页数据

thinkphp5中要想同时获得查询记录的总数量以及分页的数据, 可以用paginate(), 真的非常方便!

表结构:

CREATE TABLE `t_users` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `email` varchar(128) COLLATE utf8mb4_bin NOT NULL DEFAULT \'\' COMMENT \'登录账号\',
  `passwd` varchar(128) COLLATE utf8mb4_bin NOT NULL DEFAULT \'\',
  `nickname` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL COMMENT \'昵称\',
  `company` varchar(256) COLLATE utf8mb4_bin DEFAULT NULL COMMENT \'公司\',
  `contact` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL COMMENT \'联系人\',
  `address` varchar(256) COLLATE utf8mb4_bin DEFAULT NULL COMMENT \'详细地址\',
  `city` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL COMMENT \'城市\',
  `country` varchar(128) COLLATE utf8mb4_bin DEFAULT NULL COMMENT \'国家\',
  `province` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL COMMENT \'省/州\',
  `zip_code` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL COMMENT \'邮政编码\',
  `phone` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL COMMENT \'电话\',
  `token` varchar(128) COLLATE utf8mb4_bin DEFAULT NULL COMMENT \'登录唯一凭证, 登录时更新\',
  `check` tinyint(1) DEFAULT \'0\' COMMENT \'0-未通过, 1-通过\',
  `check_time` timestamp NULL DEFAULT NULL COMMENT \'审核时间\',
  `time` timestamp NULL DEFAULT CURRENT_TIMESTAMP COMMENT \'创建时间\',
  PRIMARY KEY (`id`),
  UNIQUE KEY `email` (`email`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin COMMENT=\'注册用户表\';

获取记录总数和分页数据:

public function test()
    {
        $r = db(self::TABLE)->paginate(3, false);
//        $r = model(self::TABLE)->paginate(3, false);
        print_r($r);

        $data = [
            \'total\'     => $r->total(),         // 总记录数
            \'cur\'       => $r->currentPage(),   // 当前页码
            \'size\'      => $r->listRows(),      // 每页记录数
            \'list\'      => $r->items()          // 分页数据
        ];

        print_r($data);
    }

 ===============================================

另外, paginate中第3个参数里可以配置请求的页码, 即请求指定页数据, 示例如下:

public function test()
    {
        $r = db(self::TABLE)->alias(\'a\')
            ->join(\'users_good b\', \'b.uid = a.id\')
            ->field(\'uid, a.check,b.chinese,b.math\')
            ->paginate(3, false, [
                \'page\'  => 2                    // 指定请求的页码
            ]);
        print_r($r);

        $data = [
            \'total\'     => $r->total(),         // 总记录数
            \'cur\'       => $r->currentPage(),   // 当前页码
            \'size\'      => $r->listRows(),      // 每页记录数
            \'list\'      => $r->items()          // 分页数据
        ];

        print_r($data);
    }
