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：
<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( $args );
?>
<?php if ( have_posts() ) : ?>
<?php while ( have_posts() ) : the_post(); ?>
...
<?php endwhile; pagenavi(); endif; wp_reset_query();
?></code>Functions.php 加了这些：
<code class="php"><?php add_filter('pre_get_posts', 'query_post_type');
function query_post_type($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 && $pages_to_show '.$first_page_text.'';
echo '<span class="extend">...</span>';
}
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 '<a href="'.esc_url(get_pagenum_link(%24i)).'" title="'.$page_text.'">'.$page_text.'</a>';
}
}
next_posts_link("»", $max_page);
if ($end_page '."...".'';
$last_page_text = str_replace("%TOTAL_PAGES%", number_format_i18n($max_page), "最后 »");
echo '<a href="'.esc_url(get_pagenum_link(%24max_page)).'" title="'.$last_page_text.'">最后 »</a>';
