thinkPHP实现签到功能的方法


            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 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！');

      }

    }

  }

  /**

  *

  * @param int $uid 用户id

  * @return array(

  *  'days'   =>  '天数',
