This function does something that isn't a major bug, but could be tweaked to function better. First, an example:

If you've got 50 records and use makepagenav(0, 15, 50, 2), you will get four buttons and they'll look like this: [1] [2] [3] ... [4]

If you go to page 4, it will look like: [1] ... [2] [3] [4]

You don't really need the "..." in these cases. They should be there if something is missing, but no page buttons are missing. If I had 65 records instead of 50, then the function shows "..." in the correct place, i.e.: [1] [2] [3] ... [5]

To allow for this kind of exception, I tweaked the function as follows:

In 7.00.05, this function is lines 753-793.
function makepagenav($start, $count, $total, $range = 0, $link = "") {

   global $locale;

   if ($link == "") { $link = FUSION_SELF."?"; }

   $pg_cnt = ceil($total / $count);
   if ($pg_cnt <= 1) { return ""; }

   $idx_back = $start - $count;
   $idx_next = $start + $count;
   $cur_page = ceil(($start + 1) / $count);

   $res = $locale['global_092']." ".$cur_page.$locale['global_093'].$pg_cnt.": ";

   if($idx_back >= 0) {
[color=#ff0000]      if ($cur_page > ($range + 1)) {
         $res .= "<a href='".$link."rowstart=0'>1</a>";
         if ($cur_page != ($range + 2)) {
            $res .= "...";
         }
      }[/color]
   }
   $idx_fst = max($cur_page - $range, 1);
   $idx_lst = min($cur_page + $range, $pg_cnt);
   if ($range == 0) {
      $idx_fst = 1;
      $idx_lst = $pg_cnt;
   }
   for ($i = $idx_fst; $i <= $idx_lst; $i++) {
      $offset_page = ($i - 1) * $count;
      if ($i == $cur_page) {
         $res .= "<span><strong>".$i."</strong></span>";
      } else {
         $res .= "<a href='".$link."rowstart=".$offset_page."'>".$i."</a>";
      }
   }
   if ($idx_next < $total) {
[color=#ff0000]      if ($cur_page < ($pg_cnt - $range)) {
         if ($cur_page != ($pg_cnt - $range - 1)) {
            $res .= "...";
         }
         $res .= "<a href='".$link."rowstart=".($pg_cnt - 1) * $count."'>".$pg_cnt."</a>\n";
      }[/color]
   }
   
   return "<div class='pagenav'>\n".$res."</div>\n";
}


I'm not sure if I made case clearly. Am I on the right track here? I've tested this, but there might something I'm missing. Does anybody want to check my work?

Tried it on a live site with 3000+ records [60 per page], works fine, well done. B)
