美好的一天!问题是:在模板类别(存档)中,当您单击404错误的第2页时,分页不起作用。 请帮忙不明白如何解决它,已经全部破了
我的循环:
<?php
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$arg = array(
'cat' => get_queried_object_id(),
'post_type'=>'post',
'posts_per_page'=>9,
//'order'=>'desc',
'paged' => $paged,
);
$query = new WP_query($arg);
if($query->have_posts()) : ?>
<section class="blog">
<?php
echo '<div class="row">';
$i=0;
$formcreated=false;
while( $query->have_posts() ) :
$query->the_post();
// display post
endwhile;
wp_reset_postdata();
endif;
?>
<div class="pagination">
<?php
if (function_exists('custom_pagination')) {
custom_pagination($query->max_num_pages,"",$paged);
}
?>
<?php wp_reset_postdata(); ?>
</div>
我的自定义分页:
function my_post_queries( $query ) {
// do not alter the query on wp-admin pages and only alter it if it's the main query
if (!is_admin() && $query->is_main_query()){
// alter the query for the home and category pages
if(is_category()){
$query->set('posts_per_page', 1);
$query->set('post_type','product');
}
}
}
add_action( 'pre_get_posts', 'my_post_queries' );
function custom_pagination($numpages = '', $pagerange = '', $paged='') {
if (empty($pagerange)) {
$pagerange = 2;
}
/**
* This first part of our function is a fallback
* for custom pagination inside a regular loop that
* uses the global $paged and global $wp_query variables.
*
* It's good because we can now override default pagination

* and custom queries.
*/
global $paged;
if (empty($paged)) {
$paged = 1;
}
if ($numpages == '') {
global $wp_query;
$numpages = $wp_query->max_num_pages;
if(!$numpages) {
$numpages = 1;
}
}
/**
* We construct the pagination arguments to enter into our paginate_links
* function.
*/
$pagination_args = array(
'base' => get_pagenum_link(1) . '%_%',
'format' => 'page/%#%',
'total' => $numpages,
'current' => $paged,
'show_all' => False,
'end_size' => 1,
'mid_size' => $pagerange,
'prev_next' => True,
'prev_text' => __('<'),
'next_text' => __('>'),
'type' => 'plain',
'add_args' => false,
'add_fragment' => ''
);
$paginate_links = paginate_links($pagination_args);
if ($paginate_links) {
echo "<nav class='custom-pagination'>";
echo $paginate_links;
echo "</nav>";
}
}

由于最近有两个不同的论坛,我正在回答这个问题。
如果您使用自定义分页,例如您使用的分页似乎来自http://callmenick.com/post/custom-wordpress-loop-with-pagination,但它也会出现在Genesis子主题中,因为父编号分页是人们所喜欢的。
为什么会有404页面? callmenick.com和Genesis(genesis_posts_nav)中的自定义分页是针对主查询的,所以如果你的分页是不同查询位于您阅读设置中的每页帖子下(为主查询设置),然后您将在第2页获得404.
WordPress网站上的每个前端页面请求都会生成一个主页 查询。 WordPress决定加载的模板基于 该主查询的结果(您可以看到WordPress的顺序 通过查看Action Reference页面来了解这些事情。尽管 事实上,你永远不会输出该查询的结果,它仍然运行, 对于分页存档,如果你这样做,这就是一个问题 试图将该分页用于不同的查询。 - Milo https://wordpress.stackexchange.com/a/120963/64742
你很多时候都没有看到这个问题,因为许多人只是为那个循环构建分页而不是从functions.php文件或父主题中重新使用它。您可以在此处了解到:https://codex.wordpress.org/Function_Reference/paginate_links
让我们从顶部开始,无论何时编码,打开wp-config.php中的调试
我的cpt档案中的基本自定义循环。
<?php $paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$product_args = array(
'post_type' => 'product',
'posts_per_page' => 2, //the same as the parse_query filter in our functions.php file
'paged' => $paged,
'page' => $paged
);
$product_query = new WP_Query( $product_args ); ?>
<?php if ( $product_query->have_posts() ) : ?>
<!-- the loop -->
<?php while ( $product_query->have_posts() ) : $product_query->the_post(); ?>
<article class="loop">
<h3><?php the_title(); ?></h3>
<div class="content">
<?php the_excerpt(); ?>
</div>
</article>
<?php endwhile; ?>
<!-- end of the loop -->
<!-- pagination here -->
<?php
if (function_exists( 'custom_pagination' )) :
custom_pagination( $product_query->max_num_pages,"",$paged );
endif;
?>
<?php wp_reset_postdata(); ?>
<?php else: ?>

在wp-include / functions.php
添加这些行
function my_pagination_rewrite() {
add_rewrite_rule('([a-z]+)/page/?([0-9]{1,})/?$', 'index.php?category_name=$matches[1]&paged=$matches[2]', 'top');
}
add_action('init', 'my_pagination_rewrite');
答案 2 :(得分:0)
我在我的网站上遇到了同样的问题 https://chronodivers.com 我有 3 个类似的网站,它们都运行相同的主题、插件、WP 版本 (5.6) 等。只有这个网站有问题。
所有网站都使用 PERMALINK 格式 /%category%/%postname%/
我尝试了插件 ( https://wordpress.org/support/view/plugin-reviews/category-pagination-fix) 对我不起作用。
然后我执行了这些简单的前端任务
将固定链接格式更改为 PLAIN 并保存。
刷新缓存
将固定链接格式改回 /%category%/%postname%/ 并保存 40 刷新缓存
我从 YOAST 插件中收到了一个“警告”,建议由于永久链接结构的变化,可能需要重建索引数据库(记不清确切的措辞)并且它提到了 WP CLI...< /p>
我只是去了 YOAST > 工具 > 优化 SEO 数据
5 完成后清除缓存
它可以工作。我已经检查了所有类别,它们都有效
这次我没有更改 PHP 文件、htaccess 等
