在网站开发过程中我们会经常用到签到功能来奖励用户积分,或者做一些其他活动。这次项目开发过程中做了日历签到,因为没有经验所有走了很多弯路,再次记录过程和步骤。
1.日历签到样式:使用的是calendar日历插件
前台代码
插件calendar.js 修改如下:
var calUtil = {
//当前日历显示的年份 showYear:2015,
//当前日历显示的月份 showMonth:1,
//当前日历显示的天数 showDays:1,
eventName:"load",
//初始化日历 init:function(signList,s=''){
calUtil.setMonthAndDay();
if (typeof(s) == 'undefined'){
}else{
signList.splice('','',s);
}
calUtil.draw(signList);
calUtil.bindEnvent(signList);
},
draw:function(signList){
//绑定日历 //alert(signList.length); // console.log(signList); if(signList.length > 21){
//alert(21); $("#sign_note").empty();
$("#sign_note").html('');
}
var str = calUtil.drawCal(calUtil.showYear,calUtil.showMonth,signList);
$("#calendar").html(str);
//绑定日历表头 var calendarName=calUtil.showYear+"/"+calUtil.showMonth+"";
$(".calendar_month_span").html(calendarName);
},
//绑定事件 bindEnvent:function(signList){
// //绑定上个月事件 // $(".calendar_month_prev").click(function(){ // //ajax获取日历json数据 // //var signList=[{"signDay":"10"},{"signDay":"11"},{"signDay":"12"},{"signDay":"13"}]; // calUtil.eventName="prev"; // calUtil.init(signList); // }); // //绑定下个月事件 // $(".calendar_month_next").click(function(){ // //ajax获取日历json数据 // //var signList=[{"signDay":"10"},{"signDay":"11"},{"signDay":"12"},{"signDay":"13"}]; // calUtil.eventName="next"; // calUtil.init(signList); // }); $(".calendar_record").click(function(){
//ajax获取日历json数据 // console(typeof(signList)+"yxy"); //var signList=[{"signDay":"10"},{"signDay":"11"},{"signDay":"12"},{"signDay":"13"}]; //var tmp = {"signDay":$(this).html()}; //if (typeof(signList) == 'undefined'){ //不做处理 //}else{ // signList.splice('','',tmp); // console.log(signList); // calUtil.init(signList); // } //alert($(this).html()); var tmp = {"signDay":$(this).html()};
console.log(tmp.signDay)
// if(tmp.signDay==11){ //执行签到 $.ajax({
type:'POST',
url:"checksign.html",
data:{day:tmp.signDay},
dataType:'json',
success:function(res){
// if(res.result==1){ // calUtil.init(signList,tmp); // }else{ alert(res.msg);
location.reload(true);
// } }
})
// }else{ // alert("请签到当天日期") // } });
},
//获取当前选择的年月 setMonthAndDay:function(){
switch(calUtil.eventName)

calUtil.showMonth=parseInt(nowMonth)+1;
if(calUtil.showMonth==13)

PHP代码的实现
//签到(status=1) public function sign(){
//当月累计签到 $sign = $this->model->table('praise')->where('uid='.$_SESSION['user']['uid'].' and time>'.strtotime(date("Y-m-01",time())))->select();
if($sign){
foreach($sign as $k=>$v){
$sign[$k]['day']=date('d',$v['time']);
}
}
//所有签到 $allsign = $this->model->table('praise')->where('uid='.$_SESSION['user']['uid'].' and status=1')->select();
$this->assign('allsign', $allsign);
$this->assign('sign', $sign);
$this->assign('user', $_SESSION['user']);
$this->display('member_sign');
} //点击签到 public function checksign(){
if($_POST['day']){
$day=intval($_POST['day']);
}else{
$day=date("d",time());
}
if($day!=date("d",time())){
$data['msg']="请在当前日期点击签到";
echo json_encode($data);
return;
}
$condition2 = 'uid='.$_SESSION['user']['uid'];
$condition2 .= " AND DATE_FORMAT(FROM_UNIXTIME(time),'%Y-%m-%d') = '".date("Y-m-d",time())."'";
$sign = $this->model->table('praise')->where($condition2)->find();
//判断是否已经签到 if (empty($sign)) {
//新增积分 $this->model->table('member')->data('integral=integral+'.$this->config['site_praise'].',allintegral=allintegral+'.$this->config['site_praise'])->where('uid='.$_SESSION['user']['uid'])->update();//增加积分 $arr['subject']="签到赠送积分";
$arr['uid'] = $_SESSION['user']['uid'];
$arr['integral'] = $this->config['site_praise'];
$arr['time']=time();
$this->model->table('member_integral')->data($arr)->insert();
$updateuser = $this->model->table('member')->where('uid='.$_SESSION['user']['uid'])->find();//购物后更新session积分 $_SESSION['user']['integral'] = $updateuser['integral'];
$_SESSION['user']['allintegral'] = $updateuser['allintegral'];
$data['uid'] = $_SESSION['user']['uid'];
//$data['pid'] = $item; $data['status'] = 1;
$data['time'] = time();
$this->model->table('praise')->data($data)->insert();
//$this->model->table('post')->data("digg=digg+1")->where('id='.$id)->update(); //$this->model->table('member_comment')->data("praise=praise+1")->where('id='.$item)->update(); $this->jssuccess('签到成功!');
} else {
$this->jserror('已经签过到了。');
}
