无法插入MySql数据库

Question

我正在使用gsm盾牌并尝试将数据发布到我的服务器，然后将其显示到网站，但在插入表格时出现问题。它只是空（0）。我尝试了我在互联网上找到的所有方法，但仍然无效。这些是我试过的一些代码

<?php

  $server = "localhost";
  $username = "id1342*****nhchuot";
  $password = "*******";
  $dbname = "id134****ta";

  $conn = mysqli_connect($server, $username, $password, $dbname);
  $Data = $_POST['data'];
  $Received = $_POST['received'];

  $query = "INSERT INTO DATA(data, received) 
  VALUES ('".$Data."','".$Received."')";
  mysqli_query($conn, $query);
  if (mysqli_query($conn, $query)) {
    echo "New record created successfully";
    } else {
    echo "Error: " .  $query . "<br>" . mysqli_error($conn);

mysqli_close($conn);?>

和数据库只有0和0
