Question

我使用Jquery和ajax将数据插入数据库，但无法使用ajax，jquery和php将任何记录插入数据库。我认为ajax的一部分正在工作，只是它无法将数据保存到数据库中，而php出了什么问题。

 <!-- JavaScript and Ajax code -->
 <script>
  $(document).ready(function(){
  $('#addrecord').click(function(event){
  event.preventDefault();
  $.ajax({
   url: "new.php",
   type:"post",
   data: $("#addnewteamform").serialize(),
   success: function(data){
    $('form').trigger("reset");
   }
   });
   });
   });
   </script>

    $sql="INSERT INTO ourteam(id, name, position, image, facebook, 
    twitter, googleplus) VALUES 
    ('$id','$name','$position','$image','$fblink','$twlink','$gplink')";

   $result=mysqli_query($db,$sql);
   if($result)
   {
      echo "true";
   }else
   { 
    echo "false"; 
   }
   ?>

请明确问题所在。谢谢。

您的表单中没有ID为$（'＃addrecord'）。click（function（event）{}）的元素
只有一个id，name，position由ajax发送的元素，但是在php中您试图访问。您尚未在文档中定义这些元素。如果您需要这些元素，请尝试先添加，然后尝试将数据发送到服务器。

另一方面，您正在使用ajax并发送仍然不存在的图像二进制文件，但是您正在使用这些$ image = $ _ FILES ['teamimage'] ['name'];

在最坏的情况下，请尝试控制台记录您的ajax返回消息，并尝试查看php实际发送的错误。

$fblink=$_POST['fblink'];
$twlink=$_POST['twlink'];
$gplink=$_POST['gplink'];
$image=$_FILES['teamimage']['name'];
$imagetmpname=$_FILES['teamimage']['tmp_name'];

仅尝试使用三个元素即可。
