mysql - mysqli_affected_rows in PHP insert

Question

I have this code:

if(mail($to, $subject, $message, $headers)){
    $insert_member_sql = "INSERT INTO members (id, username) VALUES('$id', '$username')";
    $insert_member_res = mysqli_query($con, $insert_member_sql);
    if(mysqli_affected_rows($con, $insert_member_res)>0){
    echo "1";
    }else{
    echo "0";
    }
};

All is working fine with the sending of an email and inserting the information to a database but the mysqli_affected_rows isn't working - How can I edit this code to echo 1 after running the query?

Answer 1

change this

if(mysqli_affected_rows($con, $insert_member_res)>0)

to

if(mysqli_affected_rows($con)>0)

mysqli_affected_rows only requires connection link object but you passed query object also that was the problem
