pagination – Uly.me

Here’s how to add numeric pagination on your WordPress pages.

Add this code to functions.php.

function pagination($pages = '', $range = 4) {
  $showitems = ($range * 2)+1;
  global $paged;
  if(empty($paged)) $paged = 1;
  if($pages == '') {
    global $wp_query;
    $pages = $wp_query->max_num_pages;
    if(!$pages) {
      $pages = 1;
    }
  }
  if(1 != $pages) {
    echo '<p><div class="pagination"><span>Page' . $paged . ' of  ' . $pages . '</span>   ';
    if($paged > 2 && $paged > $range+1 && $showitems < $pages) echo '<a href="' . get_pagenum_link(1) . '"><< First</a>';
    if($paged > 1 && $showitems < $pages) echo '<a href="'.get_pagenum_link($paged - 1).'">< Previous</a>';
    for ($i=1; $i <= $pages; $i++) {
      if (1 != $pages &&( !($i >= $paged+$range+1 || $i <= $paged-$range-1) || $pages <= $showitems )) {
        echo ($paged == $i)? '<span class="current">' . $i . '</span>' : '<a href="' . get_pagenum_link($i) . '"class="inactive">' . $i . '</a>';
      }
    }
    if ($paged < $pages && $showitems < $pages) echo '<a href="' . get_pagenum_link($paged + 1) . '">Next ></a>';
    if ($paged < $pages-1 && $paged+$range-1 < $pages && $showitems < $pages) echo '<a href="' . get_pagenum_link($pages) . '">Last >></a>';
    echo '</div></p>';
  }
}

To display, comment out ‘the_post_navigation’ function and add the ‘pagination’ function instead in your template files.

//the_posts_navigation();
pagination();

I had a little trouble with CodeIgniter pagination today. The pagination function is working fine, but Page 1 is always selected regardless which page I select. The data seems to be correct as I go from one page to another, but the page number doesn’t move at all. Well, after trial and error, the problem turned out to be a configuration issue.

CodeIgniter typically uses the following URI format:

http://domain.com/class/function/id.

The third segment is normally used by the pagination function for navigating from one page to another. By default, CodeIgniter pagination only uses 3 URI segments. If you are using more than 3 segments, then you will need to specify the location of the URI segment in your configuration. In my case, I’m using the fourth segment, I needed to include this setting.

$config [‘uri_segment’] = ‘4’;

If you need help with pagination, please refer to the Pagination class from the CodeIgniter User Guide.
