Thats EVERYTHING every single bit of code involved in this. Thanks for the help. Any help you can give would be amazing!

There was a CSS file as well but that shouldn't matter right?

doctor-Eggman · « **Reply #32 on:** March 18, 2010, 08:26:52 AM »

Was any of this helpful? Any idea from my mass of code what is causing the problem?

doctor-Eggman · « **Reply #33 on:** March 18, 2010, 10:30:10 AM »

I just noticed you can attach files. Here is all the source files downloaded all ready to go. I havn't touched them at all. They just dont shuffle for me.
Sorry I didn't post this before. I just noticed now that you can include files.

There is obviously something wrong in your code. Attach the files you are using and we can take a look at the full code.

doctor-Eggman · « **Reply #35 on:** March 18, 2010, 11:25:58 AM »

I did attach it. Look at the post directly above that one you posted. There is a zip file that contains everything.

Psycho · « **Reply #36 on:** March 18, 2010, 11:40:09 AM »

Yes, I DID see that. I was responding to your statements "I just noticed you can attach files ... I just noticed now that you can include files." Funny how you just noticed that today when I mentioned it yesterday.

I already copied the code from your post yesterday. I just haven't had the time to sift through it.

doctor-Eggman · « **Reply #37 on:** March 18, 2010, 11:44:20 AM »

I know I am a dofus. I thought by attach you meant just put it down. I dont know why. My head is away these past couple of days. I was posting earlier and noticed the attach thing. Sorry. But I really appreciate the help thanks.

doctor-Eggman · « **Reply #38 on:** March 22, 2010, 09:42:00 AM »

Have you had any luck mjdamato? or had a chance to look over the code at all yet?

Upon initial inspection it did seem to present the same problem, but then after playing around with it for a while it seemed to work correctly. I have to assume that it has something to do with the SESSION variables. I haven't had time to dive into it more. Personally, it wouldn't be worth my time. I could probably rewrite a better solution in less time than it would take to fix that code. But, I just don't have the time right now.

doctor-Eggman · « **Reply #40 on:** March 22, 2010, 11:45:15 AM »

You cant post the code you messed about with to get it working or anything? or what you changed to get it working correctly?
?

Well, I was only modifying the code to output data to the screen so I could see some of the internal variables to see what was going on. When it started to work I undid my changes, and it continued to work. So, the problem was not "fixed" by anything I did. That is why I assume it has something to do with the session variables.

doctor-Eggman · « **Reply #42 on:** March 22, 2010, 12:33:32 PM »

Alrighty. Well thanks for all the help much appreciated.

lynxjava · « **Reply #43 on:** April 27, 2010, 05:18:32 PM »

Hey guys,

I dont know what the big deal is.
The answer is really simple and you guys just missed out a line.
Just copy and paste this code and it would work fine.

I have highlighted in bold the missing line which should of been included.

function shuffle_assoc(&$array) {
   $keys = array_rand($array, count($array));
   shuffle($keys);
   foreach($keys as $key)
   $new[$key] = $array[$key];
     $array = $new;
return true;
   }

I found the answer by looking up some coding on the php.net

Hope this solved your problems
