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
('post','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：
$notcat,
'post__not_in' => $sticky,
'post_type'=>array( 'post','detail','jingyan','haitao'),
'posts_per_page' => 15,
'paged' => $paged
);
query_posts( $args );
?>
...
Functions.php 加了这些：
set('post_type',$post_type);
$query->set('posts_per_page', 15);
return $query;
}
}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()：
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 $before.''."\n";
if(!empty($pages_text)) {
echo ''.$pages_text.'';
}
if ($start_page >= 2 && $pages_to_show '.$first_page_text.'';
echo '...';
}
previous_posts_link("«");
for($i = $start_page; $i '.$current_page_text.'';
} else {
$page_text = str_replace("%PAGE_NUMBER%", number_format_i18n($i), "%PAGE_NUMBER%");
echo ''.$page_text.'';
}
}
next_posts_link("»", $max_page);
if ($end_page '."...".'';
$last_page_text = str_replace("%TOTAL_PAGES%", number_format_i18n($max_page), "最后 »");
echo '最后 »';
}
echo ''.$after."\n";
}
}
}
