Pagination for Twitter Bootstrap

Instructions:

Insert this into your functions.php. This snippet creates a numbered page navigation menu using Twitter Boostrap native CSS classes. Use in your template files by calling the function page_navi();.

<?php

// Numeric Page Navi

$max_page = $wp_query->max_num_pages;

if ( $numposts <= $posts_per_page ) { return; }

if(empty($paged) || $paged == 0) {

$paged = 1;

}

$pages_to_show = 7;

$pages_to_show_minus_1 = $pages_to_show-1;

$half_page_start = floor($pages_to_show_minus_1/2);

$half_page_end = ceil($pages_to_show_minus_1/2);

$start_page = $paged - $half_page_start;
