这篇文章给大家介绍如何在php项目中使用mysql和jquery实现一个日历签到功能，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。
1.日历签到样式：
2.本次签到只记录本月签到数，想要查询可以写其他页面，查询所有签到记录。（功能有，非常麻烦，古没有做。）
3.前台代码
<include file="Public:menu" />
<style type="text/css">
*{margin:0;padding:0;font:14px/1.8 "Helvetica Neue","microsoft yahei";}
</style>
<div class="ser_bx">
<div class="ser_bxc">
<span >签到记录</span>
<if condition="$res['0']['points'] eq '5'">
<div class="already btn_center">已签到</div>
<else />
<div class="ser_mbx btn_center">立即签到</div>
</if>
<div class="already btn_center" >已签到</div>
<!--<div class="minein">积分 : <span >{$poin.points}</span></div>-->
</div>
</div>
<div class="check_box">
<div >
<div id="calendar"></div>
</div>
</div>
<script type="text/javascript">
$(document).ready(function(){
$(".ser_mbx").click(function(){
$.ajax({
url:"{:U('Index/Checkin')}",

MonthSign();

</script>

<include file="Public:footer" />4.后台代码：查询今天是否签到：
$points = M('points_log');
$userid=session('user.id');
$begintime=date("Y-m-d H:i:s",mktime(0,0,0,date('m'),date('d'),date('Y')));
$endtime=date("Y-m-d H:i:s",mktime(0,0,0,date('m'),date('d')+1,date('Y'))-1);
$where=array(
'points'=>'5',
'user_id'=>$userid,
'createtime' => array(array('gt',$begintime),array('lt',$endtime)),
);
$res=$points->where($where)->order("createtime desc")->select();
//var_dump($res['0']['points']);
$this->assign('res',$res);5.查询积分：
/*查询积分*/
$jfen=M(cuser);
$list=$jfen->where(array('id'=>$userid))->field('points')->find();
$preg = '/[0]*/';
$poin = preg_replace($preg, '', $list, 1);
$this->assign('poin',$poin);6.签到写入数据库：
/*签到*/
if(IS_AJAX){
$userid=session('user.id');
$type='签到';
$typename='checkin';
$id_status='up';
$date=Date('Y-m-d H:i:s');
$dataList=array(
'user_id'=>$userid,
'type'=>$type,
'typename'=>$typename,
'id_status'=>$id_status,
'points'=>'5',
'createtime'=>$date,
'remark'=>'奖励5积分'
);
$points = M('points_log');
if($points->add($dataList)){
$log=session('user.id');
$user=M('cuser');
$user->where(array('id'=>$log))->setInc('points',5);
}
$this->ajaxReturn($status);
}7. /*查询本月签到天数，并以json格式返回*/
public function MonthSign(){
$userid=session('user.id');
$points = M('points_log');
$res=$points->where(array('user_id'=>$userid))->select();
$sign='[';
foreach($res as $key=>$value){
$first=explode(' ', $value['createtime']);
$second=explode('-', $first['0'])['2'];
if($key==0){
$sign .= '{"signDay":"'.$second.'"}';
}else{
$sign .= ',{"signDay":"'.$second.'"}';
}
}
$sign .=']';
$this->ajaxReturn($sign,'json');
}
