[SOLVED] Help with game - variables not working

[ryeman98]

Hey there, I'm making a game and in certain parts of the script the variables aren't working.  I made a Rock, Paper, Scissors game and then just changed the script to make this one.  The rps game works perfectly but this one is having problems.

 

// GLOBAL VARIABLES
$global_id = 4;
$games = mysql_query("SELECT * FROM `games` WHERE id='$global_id'");
$global_row = mysql_fetch_array($games);
$global_name = $global_row['name'];
$global_image = $global_row['img_url'];
$global_cost = $global_row['cost'];
$global_max_prize = $global_row['max_prize'];
$global_description = $global_row['description'];
// END GLOBAL VARIABLES

if ($_GET['act'] == "sessions") {
session_destroy();
$_SESSION['bust_pageview'] = 0;
$_SESSION['bust_prize'] = $global_cost;

 

As you can see, it gets the info about the game from the db and then puts it into variables. Those variables get set but when it goes to bust.php?act=choose, the variables work fine. Once it goes to bust.php?act=result, the variables then become NULL for some reason.

 

And to make matters worse, those Sessions there aren't being set at all. Any ideas?

(Yes, I have session_start(); at the beginning of the script.)

Have you verified that session_start() is at the top of the page that is not getting the data?

 

And, that you're not running the session_destroy() command between those page changes?

It is at the top and it's the exact order that my other game was in and the other game works just fine.

 

No, it's only run before the game starts so that it clears the user's previous game sessions.

If you need more info just let me know, this is pretty confusing.

I hate posting this many times in a row but I've been playing around with it all day and can't get it to work ...

We need to see more of your code.
