基于TP的每日签到代码

自己写的基于TP的每日签到代码。需要的带走，大牛勿喷
// 每日签到
public function dailySign(){
// 获取用户签到信息
$merArr = M('merchant') -> where("MerID = '$this->UserId'") -> find();
// 判断是否为注册后第一次签到
if($merArr['totalTime'] == 0 && $merArr['totalnum'] == 0){
// 获取签到设置
$signArr = M('sign') -> where("num = 1") -> find();
$Yunbi = $signArr['yun'];
$score['Mertotal'] = array('exp',"Mertotal + $Yunbi");
$score['totalnum'] = 1;
$score['totalTime'] = time();
$result = M('merchant') -> where("MerID = '$this->UserId'") -> save($score);
if($result > 0){
echo "签到成功";
}else{
echo "签到失败";
}
}else{
// 获取登录用户签到信息
$totalTime = $merArr['totalTime']; // 签到时间
$totalnum = $merArr['totalnum']; // 签到次数
$signTime = date('y-m-d',$totalTime); // 格式化签到时间
// 判断今天是否已经签到
if($signTime == date('y-m-d',time())){
echo "已签到";
exit;
}else{
// 判断是否错过连续签到时间
if(time() - $totalTime > 60*60*24){
// 获取签到设置
$signArr = M('sign') -> where("num = 1") -> find();
$Yunbi = $signArr['yun'];
$score['Mertotal'] = array('exp',"Mertotal + $Yunbi");
$score['totalnum'] = 1;
$score['totalTime'] = time();
$result = M('merchant') -> where("MerID = '$this->UserId'") -> save($score);
