PHP實作簽到功能的方法

這篇文章主要介紹了PHP實作簽到功能的方法,實例分析了mysql資料表的構造及thinkPHP簽到功能的具體實作技巧,需要的朋友可以參考下

具體如下：

資料表：

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(&#39;DB_PREFIX&#39;);
        // 日历列表
    $monthSign = $this->getMonthSign();
    $dayList = $this->showDays($monthSign);
    // 今天签到
    $data = $this->todayData();
    if($data[&#39;is_sign&#39;] == 1){
      $this->assign(&#39;isSign&#39;,true);
    }
    $this->display();
  }
  /**
  * 执行当天签到
  * @return json 签到成功返回 {status:1,info:&#39;已签到&#39;}
  */
  public function sign(){
    $todayData = $this->todayData();
    if($todayData[&#39;is_sign&#39;] == 1){
      $this->successMsg(&#39;已签到&#39;);
    }else{
      $data = $this->getInsertData($this->uid);
      // 无今天数据
      if($todayData == NULL){

        $this->successMsg(&#39;已签到&#39;,array(&#39;score&#39; => $score,&#39;days&#39;=>$data[&#39;days&#39;]));
      }else{
        $this->errorMsg(&#39;签到失败，请刷新后重试！&#39;);
      }
    }
  }
