这段代码中echo怎么不执行呢，高手给支个招

Question

Answer 1

if($_POST['action'] ==  'add' ){
条件 $_POST['action'] ==  'add' 不成立，所以 echo 不执行

Answer 2

var_dump($_POST['action']);//输出看看值是什么？确定条件成立？

Answer 3

条件是成立的，$rollback = $this->lottory_record_db->where(array('lid'=>$lid,'wecha_id'=>$wechaid,'id'=>$rid))->save($data);这句代码也是执行了的，数据库中有数据

Answer 4

那你输出的只是一个 json 串，需要 js 代码去解析呀

Answer 5

是js代码解晰的问题？
下面这段代码在同一页面，却又能弹出提示
public function exchange(){
$this->lottory_record_db=M('Lottery_record');
$this->lottory_db=M('Lottery');
$this->lottory_pw_db=M('Lottery_pw');
 if(IS_POST){
  $Lottery_pw = $this->lottory_pw_db->where(array('dpassword'=>trim($_POST['parssword'])))->find();
       
  if ($Lottery_pw['dpassword'] != trim($this->_post('parssword'))){
  echo'{"success":0,"msg":"密码不正确"}';exit;
  }else {
  $data['sendtime'] = time(); 
  $data['sendstutas'] = 1;
                $data['dname'] = $Lottery_pw['dname'];
                $data['dpassword'] = $Lottery_pw['dpassword'];
  $this->lottory_record_db->where(array('id'=> intval($_POST['rid'])))->save($data);
  echo'{"success":1,"msg":"领取成功","changed":1}';
  }
}
}

Answer 7

function alert(title)你在那里调用的？

Answer 8

$("#save-btn").bind("click",
function() {
var btn  = $(this);
var tel  = $("#tel").val();

var wechaid = $("#wechaid").val();
var winprize  = $("#winprize").val();
var sncode  = $("#sncode").val();
var lid  = $("#lid").val();
//var RegPhone = /^([0-9]{11})?$/;
//var falg;
//falg = tel.value.search(RegPhone);
if (!tel) {
alert("请输入正确{pigcms:$lottery.renametel}");
return
}
var submitData = {
sncode  : sncode,
tel  : tel,

wechaid : wechaid,
winprize:winprize,
rid: {pigcms:$Coupon.rid},
lid  : lid,
action  : "add"
};
$.post('index.php?g=Wap&m=Coupon&a=add', submitData,
function(data) {
if (data.success == true) {
alert(data.msg);
window.location.href=location.href;
//$("#zjl").hide("slow");
return
} else {

return
}
},"json")
});$("#save-btnn").bind("click",
function () {
var submitData = {

};
$.post('index.php?g=Wap&m=Coupon&a=exchange', submitData,

Answer 9

有报错误么。$record=$this->lottory_record_db->where(array('id'=>$rid))->find();   看看这条语句有没有出错呢。

Answer 10

没有哦，这条语句支掉，再把下面改成如下，还是弹不出来echo'{"success":1,"msg":"恭喜"}';
            exit;    
        }

Answer 11

if ($Lottery_pw['dpassword'] != trim($this->_post('parssword'))){
   echo'{"success":0,"msg":"密码不正确"}';exit;
   }else {
   $data['sendtime'] = time(); 
   $data['sendstutas'] = 1;
                 $data['dname'] = $Lottery_pw['dname'];
                 $data['dpassword'] = $Lottery_pw['dpassword'];
   $this->lottory_record_db->where(array('id'=> intval($_POST['rid'])))->save($data);
   echo'{"success":1,"msg":"领取成功","changed":1}';
   }
 }
 }昨晚又测试，发现密码错误的时候会提示，输入正确的时候不提示
