ofcourse php..
well. I have the folowing page contruction.
index.php -> on first line it has 'require' for start.inc.php
 I'm trying to use this code:
if (isset($_GET['myNewSize'])){
$newSize = $_GET['myNewSize'];
} else {
$newSize=125;
}
where $newSize located on config.inc.php which is required from start.inc.php after this code
And to the problem : When i'm using this code in the index file $newSize get a value as I wish but has no effect in config.inc.php.
and when using it in start.inc.php I alway get 'false'.
So what i'm asking for is something that will combine these two solution that I will get a real value from $newSize and it'll have effect where i need it.

If you like to get these files  - ftp site: ftp.oris.ws    username :public@oris.ws  password :public  
Thanx .
Ori.

Seems like a global problem.
Before using any global variable call session_start()
use $_SESSION[] array instead to pass variables between php files.

should it look something like that:
if (isset($_GET['myNewSize'])){
$_SESSION['newSize'] = $_GET['myNewSize'];
} else {
$_SESSION['newSize']=125;
}

--?

Asumming that myNewSize comes from a <FORM> and you want to save this value for many pages to use it, I guess it is OK, don't forget to call session_start() before using $_SESSION[]

Sorry. used session_start() on start.inc.php before anything else but I still get flase.
Is there any known limitation on using poseted vars in the required page? 'cause when i use it in index.php where actully it's still located logicly at the same place I get the right value.
thanx.

Then assign it to a $_POST variable where you know it has a valid value.
