$servername = "localhost";
$username = "root";

Answer 1

中有语法错误

$sql="INSERT INTO user(applicationtype,surname,givenname,title,) VALUES 
  ('$eta_type','$lastname','$firstname','$title1')";

在标题

之后删除额外的,

$sql="INSERT INTO user(applicationtype,surname,givenname,title) VALUES 
  ('$eta_type','$lastname','$firstname','$title1')";

注意：您只有关闭大括号}，假设这只是一个错误

修改

$query = mysqli_query($con, $sql) or die(mysqli_error($con));
