本文實例講述了thinkPHP實現簽到功能的方法。分享給大家供大家參考，具體如下：

數據表：

CREATE TABLE `members_sign` (
 `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
 `uid` int(11) unsigned NOT NULL COMMENT '用戶id',
 `days` tinyint(2) unsigned NOT NULL DEFAULT '0' COMMENT '連續簽到的天數',
 `is_share` tinyint(1) unsigned NOT NULL DEFAULT '0' COMMENT '是否分享過',
 `is_sign` tinyint(1) unsigned NOT NULL DEFAULT '0' COMMENT '是否簽到過',
 `stime` int(11) unsigned NOT NULL DEFAULT '0' COMMENT '簽到的時間',
 `atime` int(11) unsigned NOT NULL DEFAULT '0' COMMENT '添加時間',
 PRIMARY KEY (`id`),
 KEY `index_uid` (`uid`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=162 DEFAULT CHARSET=utf8 COMMENT='簽到分享表';

Controller：

<?php
namespace MemberController;
use MemberControllerMController;
class IndexController extends MController {
  /**
  * 用戶中心
  * @param
  */
  public function index(){
    $pre = C('DB_PREFIX');
        // 日歷列表
    $monthSign = $this->getMonthSign();
    $dayList = $this->showDays($monthSign);
    // 今天簽到
    $data = $this->todayData();
    if($data['is_sign'] == 1){
      $this->assign('isSign',true);
    }
    $this->display();
  }
  /**
  * 執行當天簽到
  * @return json 簽到成功返回 {status:1,info:'已簽到'}
  */
  public function sign(){
    $todayData = $this->todayData();
