The problem: get_next_posts_link() 在第4页消失。也就是说，“转到旧帖子”链接会在我进入后消失&paged=4 我的博客。但是，我可以手动键入eg。&paged=5 我确实收到了第五页的帖子（也就是说，帖子在那里，但是get_next_posts_link() 只是没有出现）。

So..

<打印我的帖子总数会返回正确的数量（33），这告诉我所有帖子都被正确查询了next_posts_link() 无济于事

The current code looks like this:

echo \'<ul class="blog-navi">
                <li class="blog-navi-prev">\'.get_next_posts_link($pagi_older_text, 0).\'</li>
                <li class="blog-navi-next">\'.get_previous_posts_link($pagi_newer_text).\'</li>
            </ul>\';

谢谢大家！

The posts query

get_header();

$paged = (get_query_var(\'paged\')) ? get_query_var(\'paged\') : 1;

$blogcats = $era_opts[\'era_opts_blog_thecats\'];
if(!isset($era_opts[\'era_opts_blog_thecats\'])) {
    $blogcats = \'\';
} else {
    $blogcats = implode(\',\', $blogcats);
}

$args = array(
    \'post_type\' => \'post\',
    \'numberposts\' => \'-1\',
    \'paged\' => $paged,
    \'category\' => $blogcats
);
$era_blog_posts = get_posts($args);

The added pre_get_posts function in functions.php

function era_blog_cats_wpse_103587($qry) {
  if ($qry->is_page(122) && is_main_query()) {
    $era_opts = get_option(\'era_theme_panel\');
    $blogcats = $era_opts[\'era_opts_blog_thecats\'];

    if(!empty($era_opts[\'era_opts_blog_thecats\'])) {
      $qry->set(\'category__in\', $blogcats);
    }
  }
}
add_action(\'pre_get_posts\',\'era_blog_cats_wpse_103587\');

function era_blog_cats_wpse_103587($qry) {
  if ($qry->is_page(\'your-page\') && is_main_query()) {
    $era_opts = get_option(\'era_opts\'); // assuming that era_opts are options
    $blogcats = $era_opts[\'era_opts_blog_thecats\'];
    if(!empty($era_opts[\'era_opts_blog_thecats\'])) {
      $qry->set(\'category__in\', $blogcats);
    }
  }
}
add_action(\'pre_get_posts\',\'era_blog_cats_wpse_103587\');
