A simple pagination in a few lines of code

Create a custom pagination

<?php
/* ------------------------------------------------------------------*/
/* PAGINATION */
/* ------------------------------------------------------------------*/

//paste this where the pagination must appear

global $wp_query;
$total = $wp_query->max_num_pages;
// only bother with the rest if we have more than 1 page!
if ( $total > 1 )  {
     // get the current page
     if ( !$current_page = get_query_var('paged') )
          $current_page = 1;
     // structure of "format" depends on whether we're using pretty permalinks
     if( get_option('permalink_structure') ) {
	     $format = '&paged=%#%';
     } else {
	     $format = 'page/%#%/';
     }
     echo paginate_links(array(
          'base'     => get_pagenum_link(1) . '%_%',
          'format'   => $format,
          'current'  => $current_page,
          'total'    => $total,
          'mid_size' => 4,
          'type'     => 'list'
     ));
}
?>

// CSS Code - add this to the style.css file
.navigation { list-style:none; font-size:12px; }
.navigation li{ display:inline; }
.navigation li a{ display:block; float:left; padding:4px 9px; margin-right:7px; border:1px solid #efefef; }
.navigation li span.current { display:block; float:left; padding:4px 9px; margin-right:7px; border:1px solid #efefef; background-color:#f5f5f5;  }	
.navigation li span.dots { display:block; float:left; padding:4px 9px; margin-right:7px;  }
