Ok Im feeling dumb also now *hehe* What I said about putting the $number
line below the printf line.. Donšt listen to me :) Now that I know what you
want.. I know there is cleaner and better code, but it works :)
if ($num_pages >= 2) {
for ($i=1; $i<=$num_pages; $i++) {
$j = ($i==1) ? $i : $j+20;
echo "| <a href=\"test.php?page=$j\">Page $i</a> | ";
}
}
