WordPress 在首页使用 query_posts() 分页 404？

小弟在开发时遇到个问题，思路大概是这样的：

• 设置四种文章类型('pos本#文来源gaodai$ma#com搞$$代**码网$搞代gaodaima码t','detail','jingyan','haitao)，相当于与后台的「文章」同级。

• 在首页调取四种文章类型中的所有内容，如下：

<code class="php"><?php    $paged = get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1;    $sticky = get_option( 'sticky_posts' );    $notcat = explode(',',zm_get_option('not_cat_n'));    $args = array(        'category__not_in' => $notcat,        'post__not_in' => $sticky,        'post_type'=>array( 'post','detail','jingyan','haitao'),        'posts_per_page' => 15,        'paged' => $paged    );    query_posts( $args );?><?php if ( have_posts() ) : ?><?php while ( have_posts() ) : the_post(); ?>...<?php     endwhile; pagenavi(); endif; wp_reset_query(); ?></code>

• Functions.php 加了这些：

<code class="php"><?phpadd_filter('pre_get_posts', 'query_post_type');function query_post_type($query) {  if(is_category() || is_tag()) {    $post_type = get_query_var('post_type');    if($post_type)        $post_type = $post_type;    else        $post_type = array( 'post','detail','jingyan','haitao');        $query->set('post_type',$post_type);        $query->set('posts_per_page', 15);    return $query;    }}</code>

问题来了： 按照这样的方法输出内容后，分页仅按照文章数显示。例如，「Post」下有 60 篇文章，「detail」、「jingyan」、「haitao」各 10 篇。按照想法应分 (60+10*3)/15 = 6 页。然而实际情况为翻至 60/15 = 4 页结束后，第 5、6 页均显示 404.

Copy 别人的 pagenavi()：

<code class="php"><?php // 分页显示function pagenavi($before = '', $after = '') {    global $wpdb, $wp_query,$pagenavi_options;    if (!is_single()) {        $request = $wp_query->request;        $posts_per_page = intval(get_query_var('posts_per_page'));        $paged = intval(get_query_var('paged'));        $numposts = $wp_query->found_posts;        $max_page = $wp_query->max_num_pages;        if(empty($paged) || $paged == 0){            $paged = 1;        }        $pages_to_show = intval($pagenavi_options['num_pages']);        $pages_to_show = intval(4);        $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 - $half_page_start;        if($start_page  $max_page) {            $start_page = $max_page - $pages_to_show_minus_1;            $end_page = $max_page;        }        if($start_page  1 || intval($pagenavi_options['always_show']) == 1) {            $pages_text = str_replace("%CURRENT_PAGE%", number_format_i18n($paged), "共 %TOTAL_PAGES% 页");            $pages_text = str_replace("%TOTAL_PAGES%", number_format_i18n($max_page), $pages_text);            echo $before.'<div class="pagenavi">'."\n";            if(!empty($pages_text)) {                echo '<span class="pages">'.$pages_text.'</span>';            }                               if ($start_page >= 2 && $pages_to_show < $max_page) {                $first_page_text = str_replace("%TOTAL_PAGES%", number_format_i18n($max_page), "« 第一页");                echo ''.$first_page_text.'';                echo '<span class="extend">...</span>';            }            previous_posts_link("«");            for($i = $start_page; $i  <= $end_page; $i++) {                                       if($i == $paged) {                    $current_page_text = str_replace("%PAGE_NUMBER%", number_format_i18n($i), "%PAGE_NUMBER%");                    echo '<span class="current">'.$current_page_text.'</span>';                } else {                    $page_text = str_replace("%PAGE_NUMBER%", number_format_i18n($i), "%PAGE_NUMBER%");                    echo ''.$page_text.'';                }            }            next_posts_link("»", $max_page);            if ($end_page < $max_page) {                echo '<span class="extend">'."...".'</span>';                $last_page_text = str_replace("%TOTAL_PAGES%", number_format_i18n($max_page), "最后 »");                echo '最后 »';            }            echo '</div>'.$after."\n";        }    }} ?></code>
