通过ajax和php将数据插入数据库中的问题

Question

I used Jquery and ajax to insert data into database, I can't insert any record into database by using ajax, jquery and php. I think the part of ajax is working, just it can't save the data in to database what is the problem with php.

 <!-- 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"; 
   }
   ?>

Please make clear what is the problem. thanks.

Answer 1

1. In your form there is no element with id $('#addrecord').click(function(event){})
2. There is only there element which is id,name,position is sending by ajax but in php you are trying to access. you have not defined these element in you document. If you need these element then try to add first then try to sending to data to the server.

On the other hand you are using ajax and sending image binary file which is still not there but you are using these $image=$_FILES['teamimage']['name'];

In the worst case try to console log your ajax return message and try to see what error actually php sending.

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

Try with only three element it's working.
