Wordpress 分页在自定义查询中不起作用

Question

我已经使用 front-page.php 设置了我的首页，并在第一部分显示了我最新的 bbpress 主题。我只想显示 5 个帖子和分页。但是分页不起作用。我检查了检查元素，课程即将到来，但没有链接。以下是我的代码

<ul>
                                <?php 
                                    $paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
                                    $args = array( 'post_type' => 'topic', 'posts_per_page' => 2 , 'paged' => $paged);
                                    $loop = new WP_Query( $args );
                                   if($loop->have_posts()):
                                    while($loop->have_posts()):
                                        $loop->the_post();
                                    $topic = get_the_ID();
                                    ?>
                                    <li>

                                   <?php //wp_reset_postdata(); ?>
                            </ul>

请帮我解决这个问题

Answer 1

问题在于您需要替换为$loop 的$post 变量，并且您应该检查paged 参数

如果静态首页上的分页中断，您必须添加 以这种方式“分页”参数：

if ( get_query_var( 'paged' ) ) { $paged = get_query_var( 'paged' ); }
elseif ( get_query_var( 'page' ) ) { $paged = get_query_var( 'page' ); }
else { $paged = 1; }

<ul>
    
    <?php
    if ( get_query_var( 'paged' ) ) { $paged = get_query_var( 'paged' ); }
    elseif ( get_query_var( 'page' ) ) { $paged = get_query_var( 'page' ); }
    else { $paged = 1; }
    $args = array( 'post_type' => 'topic', 'posts_per_page' => 2 , 'paged' => $paged);
    $loop = new WP_Query( $args );
    if( $loop->have_posts()):
        while($loop->have_posts()):
            $loop->the_post();
            $topic = get_the_ID();
            ?>
            <li>
                <div class="bbp_topic_data">
