Image Gallery 2.0 by Notepad - Pagination Function
Hi there,
I am using this fantastic script by notepad.
As my gallery is growing now I was wondering if anybody else using the script has changed the pagination function to include page numbers? ie:
prev 123456 next

I am not a coder myself so wouldnt know where to begin but if anybody knows of a way to do this please let us know.

Ross

RE: Image Gallery 2.0 by Notepad - Pagination Function
you'd want to focus on the navigate_images() function. which for reference i've included below.
php Code:
Original - php Code 
  1.  
  2. // draw previous and next links for images
  3. function navigate_images($total) {
  4.     global $section, $file, $prev, $next, $end, $pg;
  5.     $query = !empty($file) ? '?file='.rawurlencode($file).'&pg=' : '?pg=';
  6.     $pages = $total <= $section ? 1 : ceil($total / $section);
  7.     $p = '<<-<a href="'.SELF.$query.$prev.'">prev</a>';
  8.     $n = '<a href="'.SELF.$query.$next.'">next</a>->>';
  9.     $c = ' : page '.$pg.' of '.$pages.' : ';
  10.     
  11.     print('<div class="navigate_images">'."rn");
  12.     if(($pg == 1 && $end >= $total))
  13.         print('<<-prev'.$c.'next->>');
  14.     elseif($pg == 1)
  15.         print('<<-prev : '.$c.' : '.$n);
  16.     elseif($end < $total)
  17.         print($p.' : '.$c.' : '.$n);
  18.     else
  19.         print($p.' : '.$c.' : next->>');
  20.         
  21.     print("rn".'</div>'."rn");
  22. }

now while i won't make the changes for you, cause i don't have time, here is a similar function i wrote which does what you want. you should be able figure out how to use this example to modify the code above to your liking.
php Code:
Original - php Code 
  1.  
  2. function paginate($display, $pg, $total) {
  3.     $pages = $total <= $display ? 1 : ceil($total / $display);
  4.     $query = isset($_SERVER['QUERY_STRING']) ? '?'.$_SERVER['QUERY_STRING'].'&pg=' : '?pg=';
  5.     $first = '<a href="'.$_SERVER['PHP_SELF'].$query.'1">«</a>';
  6.     $prev = '<a href="'.$_SERVER['PHP_SELF'].$query.($pg - 1).'">‹</a>';
  7.     $next = '<a href="'.$_SERVER['PHP_SELF'].$query.($pg + 1).'">›</a>';
  8.     $last = '<a href="'.$_SERVER['PHP_SELF'].$query.$pages.'">»</a>';
  9.     
  10.     echo '<div><p align="center">';
  11.     echo $pg > 1 ? "$first : $prev :" : '« : ‹ :';
  12.     
  13.     // i want to display a max of 9 links
  14.     $begin = $pg < 6 ? 1 : $pg - 4;
  15.     $end = $begin + 8;
  16.     while($end > $pages)
  17.         $end--;
  18.     for($i=$begin; $i<=$end; $i++)
  19.         echo $i == $pg ? ' ['.$i.'] ' : ' <a href="'.$_SERVER['PHP_SELF'].$query.$i.'">'.$i.'</a> ';
  20.     
  21.     echo $pg < $pages ? ": $next : $last" : ': › : »';
  22.     echo '</p></div>'."rn";
  23. }
  24. $display = 25;
  25. $pg = isset($_REQUEST['pg']) && ctype_digit($_REQUEST['pg']) ? $_REQUEST['pg'] : 1;
  26. $start = $display * $pg - $display; // defined for database query's using LIMIT
  27. $total = count($news);

RE: Image Gallery 2.0 by Notepad - Pagination Function
okay i changed my mind and did it for you. also corrected a few of my own mistakes O_O just replace the old function with this one.
php Code:
Original - php Code 
  1.  
  2. function navigate_images($total) {
  3.     global $section, $pg; // we no longer need $file, $prev, $next, or $end
  4.     $pages = $total <= $section ? 1 : ceil($total / $section);
  5.  
  6.     if(trim($_SERVER['QUERY_STRING']) != '') {
  7.         if(stristr($_SERVER['QUERY_STRING'], 'pg='))
  8.             $query = '?'.preg_replace('/pg=d+/', 'pg=', $_SERVER['QUERY_STRING']);
  9.         else
  10.             $query = '?'.$_SERVER['QUERY_STRING'].'&pg=';
  11.     } else
  12.         $query = '?pg=';
  13.  
  14.     $first = '<a href="'.$_SERVER['PHP_SELF'].$query.'1">«</a>';
  15.     $prev = '<a href="'.$_SERVER['PHP_SELF'].$query.($pg - 1).'">‹</a>';
  16.     $next = '<a href="'.$_SERVER['PHP_SELF'].$query.($pg + 1).'">›</a>';
  17.     $last = '<a href="'.$_SERVER['PHP_SELF'].$query.$pages.'">»</a>';
  18.     
  19.     echo '<div class="navigate_images">';
  20.     echo $pg > 1 ? "$first : $prev :" : '« : ‹ :';
  21.     
  22.     // this is to display a max of 9 links
  23.     $begin = $pg < 6 ? 1 : $pg - 4;
  24.     $end = $begin + 8;
  25.     while($end > $pages)
  26.         $end--;
  27.     for($i=$begin; $i<=$end; $i++)
  28.         echo $i == $pg ? ' ['.$i.'] ' : ' <a href="'.$_SERVER['PHP_SELF'].$query.$i.'">'.$i.'</a> ';
  29.     
  30.     echo $pg < $pages ? ": $next : $last" : ': › : »';
  31.     echo '</div>'."rn";
  32. }

Question Please help with this pagination for image gallery
I am new to coding php and have used this image gallery. I love it, because it is easy to use. But I came across this pagination edit for it and followed the directions to have the different pages at the top and bottom. I would like to have this feature for the image gallery, but after clicking on two or three pages all of the thumbnails go away. I can't even get back to the first page by using the arrow. Please help, I inserted just like it said and am having issues getting the code to work.

Thank you in advance
Carrie
