Question

我无法在用户使用angular.js和PHP发布后填充数据库。单击提交按钮后，行在MySQL数据库中创建，但没有值。请在下面查看我的代码。

     </form>
  </div>
</body>
</html>

create.js：

var app=angular.module('Add_Data',[]);
app.controller('FrmController',function($scope,$http){
    $scope.errors = [];
    $scope.msgs = [];
    $scope.SignUp=function(){
        $scope.errors.splice(0, $scope.errors.length); // remove all error messages
        $scope.msgs.splice(0, $scope.msgs.length);

        $http.post('php/create.php', {'uname': $scope.username, 'pswd': $scope.userpassword, 'email': $scope.useremail}
               ).success(function(data, status, headers, config) {
                if (data.msg != '')
                    {
                        $scope.msgs.push(data.msg);
                    }
                    else
                      {
                         $scope.errors.push(data.error);
                      }
                    }).error(function(data, status) { // called asynchronously if an error occurs
// or server returns response with an error status.
                        $scope.errors.push(status);
         });
    }
});

create.php：

<?php
$data = json_decode(file_get_contents("php://input"));
$usrname = mysql_real_escape_string($data->uname);
$upswd = mysql_real_escape_string($data->pswd);
$uemail = mysql_real_escape_string($data->email);

$con = mysql_connect('localhost', 'root', '******');
mysql_select_db('AngularTest', $con);

$qry_em = 'select count(*) as cnt from users where email ="' . $uemail . '"';
$qry_res = mysql_query($qry_em);
$res = mysql_fetch_assoc($qry_res);

if ($res['cnt'] == 0) {
    $qry = 'INSERT INTO users (name,pass,email) values ("' . $usrname . '","' . $upswd . '","' . $uemail . '")';
    $qry_res = mysql_query($qry);
    if ($qry_res) {
        $arr = array('msg' => "User Created Successfully!!!", 'error' => '');
        $jsn = json_encode($arr);
        print_r($jsn);
    } else {
        $arr = array('msg' => "", 'error' => 'Error In inserting record');
        $jsn = json_encode($arr);
        print_r($jsn);
    }
} else {
    $arr = array('msg' => "", 'error' => 'User Already exists with same email');
    $jsn = json_encode($arr);
    print_r($jsn);
}

?>

当用户点击注册按钮时，会在数据库中创建一行但三个字段显示为空白。我还在页面上收到消息user created successfully。请帮我解决此错误。
