Game Help

[Luke_Watson]

Hi guys I am working on a small project for my site, the site of mine sells digital codes so I thought it would be fun to have a section where my customers can go and gamble for the chance to win a code..

 

So I have the main bulk of the application, currently the game works like the slots, you click play and 3 numbers are generated, each number = a prize you can win match 3 prizes and win a ... prize!

 

So the codes will be stored in a database and be shown on screen, and probably emailed to the winner, obviously I cant have the code sent out twice so I have a row called active, the code starts at 1 which is active and when it is sent out it is set to 0 inactive.

 

The codes are showing up fine but I need help setting the code to inactive, this is my first php project and I have little programming experience so I apologize if this seems quite a simple question 

 

So anyway here is my code for retrieving the code from the database

 

$results = $conn -> query('SELECT code FROM orders WHERE active = 1 LIMIT 1 SET active = 0');

 

so as you can see if takes a code from orders if the code is set as active, but the last lin SET active = 0 gives me the error

 

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET active = 0' at line 1' in C:\xampp\htdocs\Learning\0Casino\win.php:9 Stack trace: #0 C:\xampp\htdocs\Learning\0Casino\win.php(9): PDO->query('SELECT code FRO...') #1 {main} thrown inC:\xampp\htdocs\Learning\0Casino\win.php on line 9

 

 

Which I understand is due to poor syntax, can anyone tell me how to properly use the SET/ACTIVE properties?

 

Should I be doing this in another line or is it okay to have the code retrieved and deactivated on the same line?

 

Thanks in advance

Hi guys I have fixed the problem, I made a new line under the above which is as follows

 

$conn -> query('UPDATE codes SET Available = 0 WHERE ItemID = ' . $conn->quote($id));

 

This UPDATES the codes table and SETS Available to 0 where the ItemID is equal to that of the product ID

 

I'm just working on a way to test if a code is Available or not
