    I am coding a program that uses the id value from a url variable with a query to eventually replace data in a table. It is a program from a coding assignment I have using PHP & MySQL.

    In the details. php file there is a customer id that is passed in that I need to create a new variable for. I need also to write a conditional statement that checks to see if any value was passed in. If not, I need to echo out an error. I need to write a query to the query that uses a WHERE clause that looks for the customer id that is equal to the id variable. I need to return only one result using the bind_param() to get the results with. I also need to replace the data in the first box.

    I have googled and read through the posts that were in the first page of the search results and tried another query or two through google and read some of those results that might have matched some of the program I was trying to write but didn't have too much luck with any of those queries. And that is why I am looking for help with this coding assignment.


    details.php:
    Code:
    <?php
    
       include 'connection.php'; // includes the connection.php file to connect
       to the database
    
       // query to database and prepares and executes
       $query = "SELECT id, first_name, last_name, city, state_id, postal_code
       FROM customers ORDER BY last_name asc";
       $stmt = $db->prepare($query);
       $stmt->execute();
       $stmt->store_result();
       $stmt->bind_result($id, $first_name, $last_name);
    
       $custID = $_GET[$id];
    
       if ($custID == NULL)
           echo "<p>"You have not entered search details."</p>";
    
    ?>
