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：

namespace Member\Controller;

use Member\Controller\MController;

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

if($todayData == NULL){

$data['uid'] = $this->uid;

$data['atime'] = time();

$id = M('members_sign')->add($data);

}else{

$save = M('members_sign')->where("id = {$todayData['id']}")->save($data);

}

if($id or $save){

$score = $this->getTodayScores($data['days']);

// 为该用户添加积分

addScore($this->uid,$score);

$this->successMsg('已签到',array('score' => $score,'days'=>$data['days']));

}else{

$this->errorMsg('签到失败，请刷新后重试！');

}

}

}

/**

*

if($days){

$days++;

}

}else{

}

return array(
