check for duplicate entry vs use PDO errorInfo result

Question

I have a MySQL table which has a field for email addresses which is defined as unique. For this example, let\'s say that all my form does is allow a user to insert their em

Answer 1

A simpler way that works for me is to check the error code against an array of duplicate status codes.That way you dont have to worry what PDO returns.

$MYSQL_DUPLICATE_CODES=array(1062,23000);
try {
   $prep->execute($values);
   // do other things if successfully inserted
} catch (PDOException $e) {
   if (in_array($e->getCode(),$MYSQL_DUPLICATE_CODES)) {
      // duplicate entry, do something else
   } else {
      // an error other than duplicate entry occurred
   }
}

Thanks! :-)
