Display pagination links in groups...

My total pages is stored in the variable $total_pages
The current page is stored in the variable: $page
The total records are stored in the variable $total_records

I want to display pagination links but do not want more then 12 links

So for example:

I have 1001 total records with 10 records per page, and say for example I am viewing page 1.

I need the code to show the following

[1] .. [2].. [3].. [4].. [5].. [20]..  [40].. [60].. [80]..  [101]

If I'm on page 10, I would see (always show page 1):

[1]..[8]..[9]..[10]..[11]..[12]..[13]..[20]..[40]..[60]..[80]..[101]

The math is not exact but I think anyone reading this would get the picture (php does the divison and displays at much as it can within a maximum number of pagination links)..

Also, I just need an example (I'm an advanced PHP programmer but this is getting to me ..). The examples I saw online just show like [1] [2] [3] [100]

Here is the code I am trying:

	public function create_pagination_links($records, $limit, $current_page_num, $rsection, $view='') {
	
		$pages = ceil($records / $limit);
		$page = $current_page_num;
		$current = $page;
		
		$pagebefore = $page-1;
		$pageafter = $page+1;
		
		$output = '<ul class="pagination">';

		if($pagebefore>0) $output .="<li><a href='{$this->create_pagination_link($rsection,$pagebefore,$view)}'>&laquo;</a></li>";
		else $output .= "<li class='disabled'><span>&laquo;</span></li>";
		
		$links = array();

		if ($pages > 3) {
			// this specifies the range of pages we want to show in the middle
			$ind = 2;
			$min = max($current - $ind, $ind);
			$max = min($current + $ind, $pages-1);
			#echo $min.'-'.$max;

			// we always show the first page
			$links[] = "1";

			// we're more than one space away from the beginning, so we need a separator
			if ($min > 2) {
				$links[] = "...";
			}

			// generate the middle numbers
			for ($i=$min; $i<$max+1; $i++) {
				$links[] = "$i";
			}

			// we're more than one space away from the end, so we need a separator
			if ($max < $pages-1) {
				$links[] = "...";
			}
			// we always show the last page
			$links[] = "$pages";
		} 
		
		else {
			$links = array("1", "2", "3");
		}
		
		foreach($links AS $pagelinknum) {

			if($pagelinknum=='...') {
				$output .= "<li><span>...</span></li>";
			}
		
			else if($page==$pagelinknum) { 
				$output .= "<li class='active'><a href='{$this->create_pagination_link($rsection,$pagelinknum,$view)}'>{$pagelinknum}</a></li>";
			}
			
			else {
				$output .= "<li><a href='{$this->create_pagination_link($rsection,$pagelinknum,$view)}'>{$pagelinknum}</a></li>";
			}		
		
		}
		
		if($page<$pages) {
			$output .= "<li><a href='{$this->create_pagination_link($rsection,$pageafter,$view)}'>&raquo;</a>";
		}

		else {
			$output .= "<li class='disabled'><span>&raquo;</span></li>";
		}
		
		$output .= '</ul>';
		
		return $output;

	}
	
	public function create_pagination_link($rsection,$pagenum,$view='') {
		return "?section={$rsection}&page={$pagenum}&view={$view}";	
	}

With 876 records displaying 10 per page, this is the output I am getting:

«123...88»

I would like it to show:

1 2 3 .. 10 .. 30 .. 60 .. 80 .. 100

Figured it out:

	public function paginationHTML($page, $start_limit, $limit, $records, $URL, $RecordName) {

		$lastPage = ceil($records/$limit);
		$LINKS_PER_STEP = 5;
		
		$startofrecords = $start_limit+1;
		$endofrecords = $start_limit+10;
		if($endofrecords>$records) $endofrecords = $records;
		$showingrecords = "Page $page: Showing $RecordName Records {$startofrecords}-{$endofrecords} Of $records";

		// Nav buttons
		
		$result = '<ul class="pagination pagination-lg">';

		if ($page>1) $result .= "<li><a href='{$URL}1'>&lt;&lt;</a></li><li><a href='{$URL}{$this->ret($page-1)}'>&lt;</a></li>";
		else $result .= "<li class='disabled'><span>&lt;&lt;</span></li><li class='disabled'><span>&lt;</span></li>";

		$result .= "<li><span>&nbsp;&nbsp; $showingrecords &nbsp;&nbsp;</span></li>";
		if ($page<$lastPage) $result .= "<li><a href='{$URL}{$this->ret($page+1)}'>&gt;</a></li><li><a href='{$URL}{$lastPage}'>&gt;&gt;</a></li>";
		else $result .= "<li class='disabled'><span>&gt;</span></li><li class='disabled'><span>&gt;&gt;</span></li>";
		
		$result .= "</ul><br>";

		// Now calculate page links...

		$lastp1 = 1;
		$lastp2 = $page;
		$p1 = 1;
		$p2 = $page;
		$c1 = $LINKS_PER_STEP+1;
		$c2 = $LINKS_PER_STEP+1;
		$s1 = '';
		$s2 = '';
		$step = 1;
		while (true) {
		
			if ($c1>=$c2) {
				$s1 .= $this->paginationGap($lastp1,$p1) . $this->paginationLink($p1,$page,$URL);
				$lastp1 = $p1;
				$p1 += $step;
				$c1--;
			}
			else {
				$s2 = $this->paginationLink($p2,$page,$URL) . $this->paginationGap($p2,$lastp2) . $s2;
				$lastp2 = $p2;
				$p2 -= $step;
				$c2--;
			}
			
			if ($c2==0) {
				$step *= 10;
				$p1 += $step-1;         // Round UP to nearest multiple of $step
				$p1 -= ($p1 % $step);
				$p2 -= ($p2 % $step);   // Round DOWN to nearest multiple of $step
				$c1 = $LINKS_PER_STEP;
				$c2 = $LINKS_PER_STEP;
			}
			
			if ($p1>$p2) {
				$result .= $s1 . $this->paginationGap($lastp1,$lastp2) . $s2;
				if (($lastp2>$page)||($page>=$lastPage)) return "<ul class='pagination'>$result</ul>";
				$lastp1 = $page;
				$lastp2 = $lastPage;
				$p1 = $page+1;
				$p2 = $lastPage;
				$c1 = $LINKS_PER_STEP;
				$c2 = $LINKS_PER_STEP+1;
				$s1 = '';
				$s2 = '';
				$step = 1;
			}
		}
	}
	
		private function paginationLink($pagenumforlink, $currentpage, $URL) {
		  if ($pagenumforlink==$currentpage) return "<li class='active'><a href='{$URL}{$pagenumforlink}'>{$pagenumforlink}</a></li>";
		  return "<li><a href='{$URL}{$pagenumforlink}'>{$pagenumforlink}</a></li>";
		}	
		
		private function paginationGap($p1, $p2) {
			$x = $p2-$p1;
			if ($x==0) return false;
			else if ($x==1) return false;
			else if ($x<=10) return "<li><span> .. </span></li>";
			else if ($x<=100) return "<li><span> ... </span></li>";
			else return "<li><span> .... </span></li>";
		}
