PHP : Custom pagination in Wordpress - php

Question

I use this code for my custom paging :
global $wpdb, $table_prefix, $current_user;
get_currentuserinfo();
$umail = $current_user->user_email;
$paged = $wpdb->get_results("SELECT * FROM {$table_prefix}comments WHERE comment_author_email = '$umail'");
$page = isset($_GET['page']) ? (int) $_GET['page'] : 1;
$pages = COUNT($paged);
$pages = ceil($pages / 2);
$querystring = "";
foreach ($_GET as $key => $value) {
if ($key != "page") $querystring .= "$key=$value&";
}
// Pagination
for ($i = 1; $i <= $pages; $i++) {
echo "<a " . ($i == $page ? "class=\"selected\" " : "");
echo "href=\"?{$querystring}page=$i";
echo "\">$i</a> ";
}
This code paginate my comments look like this : 1 2 3 4 5 6 7 8 9 10 11
How can change code to get paginate look like this: 1 2 3 ... 11
Thanks for any help.

Try the following loop:
$page = 8;//current page
$pages = 15;//count of all pages
$batch_middle = 5;//the approximate number of pages in the middle links to display. Current page will be in the middle
$batch_lr = 1;//number of pages in the left and right links
for($i = 1; $i <= $pages;$i++)
{
//display first links
if ($i <= $batch_lr)
{
echo $i . ' ';
continue;
}
//display last links
if ($i > $pages-$batch_lr)
{
echo $i . ' ';
continue;
}
//display middle links
if ($i>=($page-floor($batch_middle/2)) && $i<=($page+floor($batch_middle/2)))
{
echo $i . ' ';
continue;
}
//placeholder
echo ' ... ';
//move the pointer
$i = ($i < $page) ? ($page-floor($batch_middle/2)-1) : ($pages-$batch_lr) ;
}
//output example 1: 1 2 ... 14 15
//output example 2: 1 2 ... 7 8 9 ... 14 15
//output example 3: 1 2 3 4 5 ... 14 15
//output example 4: 1 ... 6 7 8 9 10 ... 15
Replace $page and $pages with your logic with getting a current page and count of total pages.
Replace the $batch_middle and $batch_lr to configure a number of links in the first, second and third batches of the links
