Pagination Several Pages

[dweb77]

Is there an easy way to adjust this code for pagination that would handle say 100 pages such that the display is only showing 5 or 10 pages at a time then advances to the next set of pages with a next arrow, or shifts the pages to be 6-10 (if the first set was 1-5)? I have the code below which works, but it shows all pages, the next and previous buttons taking the user to each page. The code below has the variables for $start, $display, and $num_pages defined earlier in the script.

 

Thanks.

 

if ($num_pages > 1) {

$current_page = ($start/$display) + 1;

if ($current_page !=1) {

echo '<font face="Verdana" size="1"><a href="schools.php?s=' . ($start - $display) . '&no problem=' . $num_pages . '&user=' . $user . '" target="_self"><b><</b></a> · </font>';

}

for ($i = 1; $i <=$num_pages; $i++) {
if ($i !=$current_page) {

echo '<font face="Verdana" size="2"><a href="schools.php?s=' . (($display * ($i - 1))) . '&no problem=' . $num_pages . '&user=' . $user . '" target="_self"> ' . $i . ' </a> · </font>';

} else {

echo '<font face="Verdana" size="2"><b>' . $i . ' · </b></font>';
}
}


if ($current_page != $num_pages) {

echo ' <font face="Verdana" size="2"><a href="schools.php?s=' . ($start + $display) . '&no problem=' . $num_pages . '&user=' . $user . '" target="_self"><b>></b></a></font>';

}

Short answer is no, it's not easy   Here is my code:

 

<?php
function get_page_numbers($query_count, $rows_per_page, &$page_num, &$num_pages, &$first_link, &$prev_link, &$next_link, &$last_link, &$prevnext) {
  # Page number related calculations and query addition
  # $query_count is the number of items to be paged through
  $num_pages = (($query_count - ($query_count % $rows_per_page))
        / $rows_per_page);
  if ($query_count % $rows_per_page != 0) $num_pages++;
  if (!is_numeric($page_num)) $page_num = 0;
  if ($page_num > $num_pages - 1) { $page_num = 0; }

  # Information for displaying page 1 2 3 4 ... links
  if ($num_pages > 10) {
    if ($page_num >= 5) {
        $prev_link = $page_num - 5;
        $first_link = 0;
        for ($i = 0; $i < 9 && $page_num + $i - 4 < $num_pages; $i++) {
            $prevnext[$i] = $page_num + $i - 4;
        }
    } else {
        $prev_link = -1;
        $first_link = -1;
    }
    if (($num_pages - $page_num) >= 5) {
        $next_link = $page_num + 5;
        $last_link = $num_pages - 1;
        if ($page_num < 5) {
            for ($i = 0; $i < 9; $i++) {
                $prevnext[$i] = $i;
            }
        }
        # If $page_num >= 5, then list was populated earlier
    } else {
        $next_link = -1;
        $last_link = -1;
    }
  }
  if ($num_pages <= 10) {
        $prev_link = $next_link = -1;
        $first_link = $last_link = -1;
        for ($i = 0; $i < $num_pages; $i++) {
                $prevnext[$i] = $i;
        }
  }
}
?>
