Check if update query was successful [PHP, mysqli] [duplicate]

Answer 1

pass your mysqli connection object ($connection) to mysqli_affected_rows(connection_object) to check affected rows.

connection_object is like - $con=mysqli_connect("localhost","bd_user","db_password","your_db_name");

So , code will be

if(mysqli_affected_rows($con)== 1 ){ 
   header("location: ../index.php"); 
}
