Karen,
I'm assuming that when you say:
> For some reason,
> when Previous/Next are clicked, the value passed is still 15
> even though the pulldown says something else (5 or 15 or
> whatever)
you're drawing that conclusion because 15 images (or whatever) are displayed
on the resulting page regardless of what you select in the pulldown. Does
the actual URL say 15 or does it say something else (e.g. 20)?
If the URL shows that pagesize=15, but the resulting page displays 20
images, it's possible the problem is that you're not checking the actual
value passed in the URL.
Your current code:
If(!$pagesize)
{
$pagesize=15;
}
Should read:
If(!$_GET["pagesize"]){
$pagesize=15;
}
Else{
$pagesize = $_GET["pagesize"];
}
This is assuming that you have register globals turned off (I think that's
right). Because, otherwise, each time the page loads with your current code,
$pagesize would never be set and would always default to 15.
Hope this helps.
