WordPress Numeric Pagination

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();
