Question

我有一个从Ajax接收数据的PHP文件但是在收到数据后我使用json_encode从php发送成功消息，但是即使SQL查询成功，也会收到消息error is hit 。这个过程适用于localhost，但是当我将它上传到主服务器时出现错误。

这是我的JS文件： $（function（）{ $（“＃userReg_btn”）。click（function（e）{ //用户注册

            var array = [];
            var flag = false;

            var firstName = $("#uFn").val();
            var lastName = $("#uLn").val();
            var email = $("#uEa").val();
            var pass = $("#uPn").val();
            var mobile = $("#uMn").val();
            var nID = $("#uNm").val();
            var age = $("#uAn").val();
            var prof = $("#uPc").val();


            if (firstName == "" || lastName == "" || email == "" || pass == "" || mobile == "" || nID == "" || age == "" || prof == "") {
                e.preventDefault();
                alert("Please provide some input");
                flag = false;
            } else if (mobile.length != 11 || nID.length != 17) {
                e.preventDefault();
                alert("Please provide correct input");
                flag = false;
            } else {
                array.push(firstName);
                array.push(lastName);
                array.push(email);
                array.push(pass);
                array.push(mobile);
                array.push(nID);
                array.push(age);
                array.push(prof);

                alert(array);
                console.log(array);
                flag = true;
            }

            if (flag == true) {
                $.ajax({
                    url: "http://demoname.co/CustomerRegistration.php",
                    data: {
                        firstName: array[0],
                        lastName: array[1],
                        email: array[2],
                        pass: array[3],
                        mobile: array[4],
                        nID: array[5],
                        age: array[6],
                        prof: array[7]
                    },
                    type: "POST",
                    dataType: "json",
                    success: function(suc) {
                        alert("in success");
                        alert(suc);
                        console.log("success");
                    },
                    error: function(err) {
                        alert("error is hit");
                        alert(err);
                        console.log(err);
                    }
                });
            } else {
                alert("Form error");
            }
            alert("USer Reg");

        });

这是我的PHP文件：

<?php

        header('Cache-Control: no-cache, must-revalidate');
        header('Expires: Mon, 01 Jan 2016 00:00:00 GMT');

        // The JSON standard MIME header.
              header('Content-type: application/json');
             $con=mysql_connect("localhost","username", "password");
             mysql_select_db("database name",$con);

                $fname = $_POST['firstName'];
                $lname=$_POST['lastName'];
                $username=$_POST['email'];
                $password=$_POST['pass'];
                $phone=$_POST['mobile'];
                $nid=$_POST['nID'];
                $age=$_POST['age'];
                $profession=$_POST['prof'];

                $query="INSERT INTO customerregistration(FirstName,LastName,Username,password,PhoneNumber,NID,Age,Profession) VALUES('$fname','$lname','$username','$password','$phone','$nid','$age','$profession');";




           if(mysql_query($query))
           {
              $suc= 'success';
              echo json_encode($suc);
           }
        else
    {
           echo  mysql_error();

    }

?>

从PHP发送到Ajax成功后出错？
