Trying to update column value for specific row only? - php

Question

I am having some problems with a script, I am basically inputting data into a MySQL table. This data will be inserted in the table as 1 row.
Upon a row of data being entered into the table I want the current/specific row currently being entered to have the column 'account_type' to be updated from its default value 'member' to 'client'.
It's a long story why I need to do it this way but I do not want to simply just enter the value 'client' it must be updated from 'member' to client.
The script I have (which is the bit at the bottom) is currently doing just this but it is affecting all rows in the table, is there a way I can add a where clause to the update to say only affect the current row being entered and do not update all other rows in the table?
<?php ob_start();
// CONNECT TO THE DATABASE
require('../../includes/_config/connection.php');
// LOAD FUNCTIONS
require('../../includes/functions.php');
$username = $_POST['username'];
$password = $_POST['password'];
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$email = $_POST['email'];
$number = $_POST['number'];
$dob = $_POST['dob'];
$accounttype = $_POST['accounttype'];
$query="INSERT INTO ptb_registrations (
username,
password,
firstname,
lastname,
email,
number,
dob,
accounttype,
date_created )
VALUES(
'".$username."',
'".$password."',
'".$firstname."',
'".$lastname."',
'".$email."',
'".$number."',
'".$dob."',
'".$accounttype."',
now()
)";
mysql_query($query) or die();
$query="INSERT INTO ptb_users (
first_name,
last_name,
email,
password )
VALUES(
'".$firstname."',
'".$lastname."',
'".$email."',
MD5('".$password."')
)";
mysql_query($query) or dieerr();
$result = mysql_query("UPDATE ptb_users SET ptb_users.user_id = ptb_users.id,
ptb_users.account_type = 'Client'");

Answer 1

Please, don't use mysql_* functions in new code. They are no longer maintained and are officially deprecated. See the red box? Learn about prepared statements instead, and use PDO, or MySQLi - this article will help you decide which. If you choose PDO, here is a good tutorial.
You can use the MySQL function LAST_INSERT_ID() to do this.
The old ext/MySQL extension exposes this functionality through mysql_insert_id(), but you can also access it directly, and more cleanly, and safely, in a query.
So you can do something like this:
$result = mysql_query("
UPDATE ptb_users
SET ptb_users.user_id = ptb_users.id,
ptb_users.account_type = 'Client'
WHERE id = LAST_INSERT_ID()
");
I know you say "it's a long story..." But what you are doing makes little-to-no sense. I can only imagine you are doing this because of a trigger - and that demonstrates quite nicely why triggers are generally a bad idea ;-)
Please try and re-think your design if at all possible.

Answer 2

Get the inserted ID after your first query then use it in the update (assuming you have a primary key with auto-increment).

Answer 3

Try With WHERE Condition on unique coloumn
mysql_query("UPDATE ptb_users SET ptb_users.user_id = ptb_users.id,
ptb_users.account_type = 'Client'" WHERE ptb_user.email='$email');
