Question

I am working on a project which allows me to create a customer database. I have made an Create.php and Delete.php but am having issues with the basic structure for an Edit page.

My initial idea is to create a populated drop down box (Which I can do) which on click will take the user to domain.com/Customer.php?Customer_name=”JohnD”

I am having a few issues with regards to this as it is doing 2 things.

1. It is printing out ALL of the data in my table into the echo.
2. It isn’t taking the values from the URL, However I know that I have missed something but am unsure of what I need to search for.

Here is my snippet so far:

               <h2>
                <?Php
                $sql="SELECT id,customer_name FROM Customers";
                $result =mysql_query($sql);
                while ($data=mysql_fetch_assoc($result)){
                ?>
                <?Php echo $data['customer_name']; } ?>
                </h2>

As of yet I am getting this in the header:

John Doe Jimmy Timmy Test

These are all the values inside my rows for the table Customers.

Sorry if the question seems all over the place. I will correct if it is not easy to understand.

Thanks in advance

Answer 1

use this url

domain.com/Customer.php?CID=1

and the code should look like

<?php

            $customer_id = (int) $_GET['CID'];

            $query = "SELECT id, customer_name FROM Customers 
                           WHERE id = {$customer_id}";

            $result = mysql_query($query) or die('<p>' . $query . '</p><div>' . 
                                   mysql_error() . '</div>');

            $customer = mysql_fetch_assoc($result);  

?>
 <h2><?php echo $customer['customer_name'] ?></h2>
