Answer 1

你有

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

语法错误标题后删除多余的,

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

注：你只是右括号}的连接，假设这只是一个错字

编辑

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