Guess that's what I get for just typing it in. They should all be the
same, that's not the issue here.
If I'm reading your post right, it would be the same as reworking
common.php to have it check for the session and if it's not there,
start it up. I'm using XAMP right now, as I'm just developing stuff,
so I don't have to worry about timeouts, but I will keep that in mind
for later.
I changed my common.php as I just described, and still get the same
error. It's related to the session somehow, but I'm not sure how yet.
Here's the message I get:
Fatal error: main() [<a href='function.main'>function.main</a>]: The
script tried to execute a method or access a property of an incomplete
object. Please ensure that the class definition "Output" of
the object you are trying to operate on was loaded _before_
unserialize() gets called or provide a __autoload() function to load
the class definition in C:\xampplite\htdocs\game\characterselect.php on
line 16
>From this, you can see that it's trying to run a function from the
Output class (something I'm working on changing actually, it's a little
too cumbersome the way it is now). Line 16 says this $out->clear();
Basicly, $out is mapped to $_SESSION['output'], and clear() just makes
sure the output is empty so I can write new information to it.
Does this give any more clues? I am including my lib/output.php file,
and I just made sure that it was loading it, it is. Here are lines 15
and 16, just as a clarification:
$out = &$_SESSION['output']; // $out is refrenced to the session
variable
$out->clear(); // clear the output
