PDO更新不更新数据

Question

I know an answer like this has been written countless amounts of time but honestly after spending about 4 hours on this, I can't seem to find whats wrong. My PDO Update is not updating. It was working a few days ago and maybe I have changed something but it doesn't work at all now.

 try {
     $query_update = $db->db_connection->prepare('UPDATE ghl_users SET user_last_reset_code = :user_password_reset_hash,
                                                           user_last_reset_request = :user_password_reset_timestamp
                                                           WHERE user_name = :user_name');
     $query_update->bindValue(':user_password_reset_hash', $user_password_reset_hash, PDO::PARAM_STR);
     $query_update->bindValue(':user_password_reset_timestamp', $temporary_timestamp, PDO::PARAM_STR);
     $query_update->bindValue(':user_name', $user_name, PDO::PARAM_STR);
     $query_update->execute();
}catch( PDOException $Exception ) {
   throw new MyDatabaseException( $Exception->getMessage( ) , (int)$Exception->getCode( ) );
}

all variables are set (eg when I echo it shows me the values)

 echo $user_name. "<br />";
 echo $temporary_timestamp. "<br />";
 echo $user_password_reset_hash. "<br />";

Values are:

You only need to parameterise unsafe values , $user_password_reset_hash , to stop injection. You can use SQL NOW() to update

Try

 try {
 $query_update = $db->db_connection->prepare('UPDATE ghl_users 
                                    SET user_last_reset_code = :user_password_reset_hash,
                                                       user_last_reset_request = NOW()
                                                       WHERE user_name = :user_name');
 $query_update->bindValue(':user_password_reset_hash', $user_password_reset_hash, PDO::PARAM_STR);
 $query_update->bindValue(':user_name', $user_name, PDO::PARAM_STR);
 if ($query_update->execute())
      {
      // success
       echo "Updated record";
     }
    else
    {
      // failure

   }



}catch( PDOException $Exception ) {
   throw new MyDatabaseException( $Exception->getMessage( ) ,  (int)$Exception->getCode( ) );
}

Also Ensure ERRMODE_EXCEPTION is set
