自从从PHP 7.4更新到PHP 8以来，我的error_log 现在，我使用的一个儿童主题中充满了这样的行：

【2021 10月17日13:30:38 UTC】PHP警告：尝试读取属性；term\\u id；在bool-in/public\\u html/wp内容/主题/主题名子项/函数。php在线181

这是抛出错误的块。它用于修改分页，以便不导航特定类型（链接）的帖子。

// modify pagination to exclude post_format of \'link\' on news/blog posts
function profound_navigation() {
    $previous = ( is_attachment() ) ? get_post( get_post()->post_parent ) : get_adjacent_post( false, \'\', true );
    $next     = get_adjacent_post( false, \'\', false );
    if ( ! $next && ! $previous ) {
        return;
    }
    $link_term = get_term_by(\'slug\' , \'post-format-link\' , \'post_format\');
    $quote_term = get_term_by(\'slug\' , \'post-format-quote\' , \'post-format\');

    the_post_navigation(
            array(
                    \'next_text\' => \'<span class="meta-nav">Next Article <i class="flaticon-right-arrow"></i></span><h3 class="title">%title</h3>\',
                    \'prev_text\' => \'<span class="meta-nav"><i class="flaticon-left-arrow-1"></i> Previous Article</span><h3 class="title">%title</h3>\',
                    // \'taxonomy\' => \'post_format\',
                    \'excluded_terms\' => array($link_term->term_id, $quote_term->term_id, 156),
            )
    );
}
