wordpress分页函数，不是插件！

functions.php中

//分页
function par_pagenavi($range = 9){
    global $paged, $wp_query;
    if ( !$max_page ) {$max_page = $wp_query->max_num_pages;}
    if($max_page > 1){if(!$paged){$paged = 1;}
        if($paged != 1){echo "<a href='" . get_pagenum_link(1) . "' class='extend' title='跳转到首页'> 返回首页 </a>";}
        previous_posts_link(' 上一页 ');
        if($max_page > $range){
            if($paged < $range){for($i = 1; $i <= ($range + 1); $i++){echo "<a href='" . get_pagenum_link($i) ."'";
                if($i==$paged)echo " class='current'";echo ">$i</a>";}}
            elseif($paged >= ($max_page - ceil(($range/2)))){
                for($i = $max_page - $range; $i <= $max_page; $i++){echo "<a href='" . get_pagenum_link($i) ."'";
                    if($i==$paged)echo " class='current'";echo ">$i</a>";}}
            elseif($paged >= $range && $paged < ($max_page - ceil(($range/2)))){
                for($i = ($paged - ceil($range/2)); $i <= ($paged + ceil(($range/2))); $i++){echo "<a href='" . get_pagenum_link

($i) ."'";if($i==$paged) echo " class='current'";echo ">$i</a>";}}}
        else{for($i = 1; $i <= $max_page; $i++){echo "<a href='" . get_pagenum_link($i) ."'";
            if($i==$paged)echo " class='current'";echo ">$i</a>";}}
        next_posts_link(' 下一页 ');
        if($paged != $max_page){echo "<a href='" . get_pagenum_link($max_page) . "' class='extend' title='跳转到最后一页'> 最后一页 

</a>";}}
}

 css中

/* -----------page nav-------*/
.page_navi{width:100%;height:80px;line-height:36px;text-align:center;overflow:hidden;padding-top:1em;}
.page_navi a{padding:3px 8px;margin:2px;text-decoration:none;color:#888;border:1px solid #ccf;}
.page_navi a:hover,.page_navi a.current{border:1px solid #356aa0;color:#356aa0;font-weight:bolder;}

 在页面中category.php中调用

<div class="page_navi"><?php par_pagenavi(); ?></div>
