所以我有一个博客，按类别过滤，然后按城市过滤。在创建过滤的过程中，我打破了之前似乎工作正常的分页。它在我的主页上不起作用，它应该显示所有帖子，并转到我档案中的404。我正在使用的自定义链接结构/%category%/%postname%/ 在我的索引页中，我有：
<p align="center" id="space">
<?php posts_nav_link(\' - \',__(\'« Newer Posts\',\'ml\'),__(\'Older Posts »\',\'ml\')) ?>
</p>
在我的档案页面上也是一样。我创建了一个过滤所有内容的函数，这就是分页应该发生的地方：
From.phphttp://pastebin.com/d9jikfPq
$testParent = $wp_query->get_queried_object();
function cust_query($city, $cat)// Filter and page everything by city/cat
{
$setCity = false;
$setCat = false;
$paged = get_query_var(\'paged\') ? get_query_var(\'paged\') : 3; // Seperates Posts into Pages
$citySlug = get_category_by_slug($city); // Used to get City && Category CatID
$categorySlug = get_category_by_slug($cat); // ^^^
if(isset($cat) && $cat != null) // Check if $cat is set
{
$category = $categorySlug->cat_ID; // Setting Category CatID
$setCat = true;
}
if(isset($city) && $city != null) // Check if $city is set
{
$city = $citySlug->cat_ID; // Setting City CatID
$setCity = true;
}
if($setCity && $setCat && !$testParent->parent) // If both cat and city are set filter by both
{
/*

*/
if(!$testParent->parent)
{
$args = array(
\'tax_query\' => array(
\'relation\' => \'AND\',
array(
\'taxonomy\' => \'category\',
\'field\' => \'id\',
\'terms\' => $city,
),
array(
\'taxonomy\' => \'category\',
\'field\' => \'id\',
\'terms\' => $category,
)
)
);
$args = array_merge( $args, array( \'paged\' => $paged ) );
return query_posts($args); // Return Query
}
return query_posts(array(category__and => array($category, $city), \'paged\' => $paged)); // Return Query
}
if($setCity) // Filter by City Only
return query_posts(\'cat=\'.$city.\'&paged=\'.$paged); // Return Query
else if($setCat) // Filter by Category Only
return query_posts(\'cat=\'.$category.\'&paged=\'.$paged); // Return Query
else
return query_posts(\'paged=\'.$paged); // Return all posts
}

上述函数通过需要过滤的城市/类别，然后根据是否同时设置了这两个城市/类别或仅设置了一个城市/类别，它将过滤并分页。除了它没有页面。。。有什么建议吗？我还想指出，我的索引文件没有循环，它只使用query\\u posts（）和
changing the number inside $paged = get_query_var(\'paged\') ? get_query_var(\'paged\') : 3; to anything except 1 puts all my pages to 404. If I make it 1 then it shows all posts and pages index fine... 为什么会这样？我可以做些什么来防止这种情况发生？
最合适的回答,由SO网友:Stephen Harris 整理而成
这个posts_per_page 指每页的帖子数量，而不是您正在查看的页面。为此，您需要设置paged 论点看到了吗Codex on WP_Query 还有这个article by Scribu.
使用paged 参数集，它将根据页码返回相应的帖子（第一页的前x篇帖子，第二页的下x篇帖子等）。如果不是，您总是查询前x篇文章，因此每个页面都是一样的。
例如
query_posts($args, \'posts_per_page=\'.$paged);
使用
$args = array_merge( $args, array( \'paged\' => $paged ) );
query_posts($args);
而不是
query_posts(\'posts_per_page=\'.$paged);
使用
query_posts(\'paged=\'.$paged);
