I don’t quite understand which part of the code is used to transfer the data entered by the user to the database
$insert_sql="insert into user(username,password)values(? , ? )";
$stmt=mysqli_prepare($link,$insert_sql);
mysqli_stmt_bind_param($stmt,'ss',$name,$pwd);
$result_insert=mysqli_stmt_execute($stmt);

$insert_sql="insert into user(username,password)values(? , ? )";

$result_insert=mysqli_stmt_execute($stmt);
