此功能是用于wordpress首页分页的函数，闲话少说了，这篇文章是为前一篇文章准备的。
首先在主题functions.php里面加入分页功能函数：
function pagination($query_string){
global $posts_per_page, $paged;
$my_query = new WP_Query($query_string .”&posts_per_page=-1″);
$total_posts = $my_query->post_count;
if(empty($paged))$paged = 1;
$prev = $paged – 1;
$next = $paged + 1;
$range = 8; // 如果你想展示更多分页链接，修改它！
$showitems = ($range * 2)+1;
$pages = ceil($total_posts/$posts_per_page);
if(1 != $pages){
echo “<div class=’pagination’>”;
echo ($paged > 2 && $paged+$range+1 > $pages && $showitems < $pages)? “<a href='”.get_pagenum_link(1).”‘>最前一页</a>”:””;
echo ($paged > 1 && $showitems < $pages)? “<a href='”.get_pagenum_link($prev).”‘>上一页</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>”; } }
echo ($paged < $pages && $showitems < $pages) ?”….<a href='”.get_pagenum_link($next).”‘>下一页</a>” :””;
echo ($paged < $pages-1 && $paged+$range-1 < $pages && $showitems < $pages) ? “<a href='”.get_pagenum_link($pages).”‘>最后一页</a>”:””;
echo “</div>\n”; }} ?>
然后在首页调用分页函数：<?php pagination($query_string); ?>
ok，完成，你可以在首页查看到分页了，修改红色的数字8，8代表这默认展示8个分页数字链接。
