if(isset($_POST['but_upload'])){
 
  $name = $_FILES['file']['name'];
  $target_dir = "upload/";
  $target_file = $target_dir . basename($_FILES["file"]["name"]);

  // Select file type
  $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

    // Convert to base64 
    $image_base64 = base64_encode(file_get_contents($_FILES['file']['tmp_name']) );
    $image = 'data:image/'.$imageFileType.';base64,'.$image_base64;
