[RESOLVED] Newbie : Link not working correct in the LOOP

[phpmaddog]

Hello community :

I have created a for loop to be able to display the link to another page once there is 9 rows displayed on one page t will create a another link to go to page 2 and then page 3 and then page ..... so on.

But when I'm in on page 1 and then click on page 2 it gives error.

The link to where it points and gives error to page 2 is :
http://www.fakedomain.com/product.php?catid=&subcatid=&page=2

When I manually put in the URL of the web browser the numbers 8 21 it works fine
http://www.fakedomain.com/product.php?catid=8&subcatid=21&page=2

Seems the loop is not processing it.

Here is the for loop code :

for($page = 1; $page <= $totalPage; $page++)
{
if ($page == $pageNum)
{
$nav .= " $page "; // no need to create a link to current page
}
else
{
$nav .= " <a href=\"$self?catid=$catid&subcatid=$subcatid&page=$page\">$page</a> ";
}
}
if($totalPage > 1) {
echo "<tr><td colspan=3 class=subcategory align=right width='100%'>";
echo $nav;
echo"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</td></tr>";
}
?>

I truly appreciate the help. I have been looking all around in this code and no luck so far.

Thanks.

$catid and $subcatid are obviously not defined

Thanks dagon. You rock a million.

I did add this to the code and is working smoothly and faster . I feel good and happy now.

$catid = $row['categoryid'];
$subcatid = $row['subcategoryid'];
