Your problem is that you are only exiting if both prepares (of $stmt1
and $stmt2
) fail, where you should exit if either of them fail. Change this line:
if(!mysqli_stmt_prepare($stmt1,$sql1) && !mysqli_stmt_prepare($stmt2,$sql2)){
to
if(!mysqli_stmt_prepare($stmt1,$sql1) || !mysqli_stmt_prepare($stmt2,$sql2)){
You should also use mysqli_error()
to find out why the prepare failed, perhaps adding that to the location you redirect to eg
header("Location: ../register.php?error=sqlerror&msg=" . urlencode(mysqli_error($conn)));
Your other problem is that you have a typo, mysqli_bind_param
should be mysqli_stmt_bind_param
on line 78.
