本文实例讲述了thinkPHP实现签到功能的方法。分享给大家供大家参考，具体如下：
数据表：
CREATE TABLE `members_sign` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `uid` int(11) unsigned NOT NULL COMMENT '用户id', `days` tinyint(2) unsigned NOT NULL DEFAULT '0' COMMENT '连续签到的天数', `is_share` tinyint(1) unsigned NOT NULL DEFAULT '0' COMMENT '是否分享过', `is_sign` tinyint(1) unsigned NOT NULL DEFAULT '0' COMMENT '是否签到过', `stime` int(11) unsigned NOT NULL DEFAULT '0' COMMENT '签到的时间', `atime` int(11) unsigned NOT NULL DEFAULT '0' COMMENT '添加时间', PRIMARY KEY (`id`), KEY `index_uid` (`uid`) USING BTREE ) ENGINE=InnoDB AUTO_INCREMENT=162 DEFAULT CHARSET=utf8 COMMENT='签到分享表';
Controller：
<?php
namespace MemberController;
use MemberControllerMController;
class IndexController extends MController {
/**
* 用户中心
* @param
*/
public function index(){
$pre = C('DB_PREFIX');
// 日历列表
$monthSign = $this->getMonthSign();
$dayList = $this->showDays($monthSign);
// 今天签到
$data = $this->todayData();
if($data['is_sign'] == 1){
$this->assign('isSign',true);
}
$this->display();
}
/**
* 执行当天签到
* @return json 签到成功返回 {status:1,info:'已签到'}
*/
public function sign(){
$todayData = $this->todayData();
if($todayData['is_sign'] == 1){
$this->successMsg('已签到');
}else{
$data = $this->getInsertData($this->uid);
// 无今天数据

// 为该用户添加积分

$this->successMsg('已签到',array('score' => $score,'days'=>$data['days']));
}else{
$this->errorMsg('签到失败，请刷新后重试！');
}
}
}
