WordPress分页不会切换页面

Posted 2021-05-01

我一直在寻找这个问题的解决方案超过一个星期，我找不到其他人遇到同样的麻烦。

我正在开发一个其他人建立的自定义WP主题。有一个单页模板，我需要为其中一个辅助循环实现分页。我一直在尝试使用内置的paginate_links()函数以及其他方法。分页链接显示，但是当我点击分页链接时，它不会在分页中转到该页面。而是重新加载原始页面（即，不是访问网站http://www.my-page/page/2/，而是重新加载网站http://www.my-page/）。

前面的dev在functions.php中使用了这个过滤器来加载正确的模板：

add_filter('single_template', create_function('$t', 'foreach( (array) get_the_category() as $cat ) { if ( file_exists(TEMPLATEPATH . "/single-{$cat->slug}.php") ) return TEMPLATEPATH . "/single-{$cat->slug}.php"; } return $t;' ));

这是我的模板文件：

<?php
/**
* Template Name: Project Template
*/
get_header('news'); ?>

<article role="main" class="projectpage">
<div class="container">
  <section class="pagecontent">


      <?php if ( have_posts() ) : while ( have_posts() ) : the_post();  ?>
      <section class="overview">
          <h1><?php the_title(); ?></h1>
          <div>
              <?php the_content(); ?>
          </div>
          <div>
              <?php if(get_post_meta($post->ID, 'pagelink', true)): ?>
                  <a href ="<?php echo get_post_meta($post->ID, 'pagelink', true); ?>" class="ctabutton2">  Read the Overview </a>
              <?php endif; ?>
          </div>

</div><!--end row-->

   <?php endwhile ?>

我意识到有一整套WordPress分页教程和线程在那里，但我还没有找到一个解决这个特殊问题。

答案

我认为你的代码应该主要起作用。你不需要担心$wp_query的所有保存和切换 - 你尝试过这个更简单的片段吗？它在我的环境中工作正常（虽然我不得不稍微修改查询args以使其返回任何结果）。

如果这不起作用，你可以发布它生成的html吗？

        <section class="articles">
          <?php
//  THIS IS THE SECTION WHERE I NEED THE PAGINATION
          $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;

          $args = [
            'posts_per_page' => 3,
            'paged' => $paged,
            'post_type' => 'post',
            'order' => 'DESC',
            'post__not_in' => array( $post->ID ),
            'tax_query' => [
            [
                'taxonomy' => 'category',
                'field'    => 'term_id',
                'terms'    => '93',
            ],
          ],
        ];

        $custom_query = new WP_Query( $args );
                            if ( $custom_query->have_posts() ) {
                                while ( $custom_query->have_posts() ) {
                                    $custom_query->the_post(); ?>
                                <div class="row">

另一答案

谢谢，乔！那篇文章指出了我正确的方向。我检查了开发工具，我确实得到了301.我尝试了你指向我的文章中的代码片段，但它不太有效，所以我用Google搜索“修复与redirect_canonical的分页”和this was the first article that popped up。我从那里拿了这个函数，把它扔进了functions.php，etvoilà！它是相同的方法，但我认为，不会将自定义帖子类型传递给条件。我希望这可以帮助将来的某个人。真是太痛苦了。这也提醒我，我对WP的了解非常少，我想了解它多少！再次感谢。

这是代码：

add_filter('redirect_canonical','custom_disable_redirect_canonical');
function custom_disable_redirect_canonical($redirect_url) {
    if (is_paged() && is_singular()) $redirect_url = false;
    return $redirect_url;
}
