自定义日期事件的回退条件

Question

需要一点帮助来纠正我的后备条件。我有 3 个不同的选项卡事件，正在发生、即将发生和已过期。我这里的当前代码设置为 "happening event"，如果存在 "no current happening event"，则很难理解如何或在何处放置回退。如果我创建后备条件，它最终会复制 "No Current Events Set" 的消息。我应该在哪里放置条件以使回退不复制其消息。

<div role="tabpanel" class="tab-pane active" id="happening">
<?php
  if ( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post();
    // Check event record from ACF
    while ( have_rows('dtl') ) : the_row();
      $date = DateTime::createFromFormat('Ymd', get_sub_field('event_date'));
      $dateA = $date->format('Y-m-d');
      $dateB = date('Y-m-d');
    endwhile; 

    // Compare event record from ACF & current date
    if (strtotime($dateA) == strtotime($dateB)) :
  ?>
  <section class="section-contents"><?php get_template_part( 'templates/events', 'query' ); ?></section>
  <?php else : // fallback if there's no active date ?>
  <section class="section-contents"> <h5 class="text-center text-danger text-uppercase">No Current Events Set</h5> </section>
  <?php endif; // close strtotime
  endwhile; endif; wp_reset_postdata(); 
?>
</div>

你在循环中有你的 else 条件，这意味着它会为你的时间比较失败的每次迭代输出你的消息。您需要将其移出循环

 $x=false;
 if ( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post();
    // Check event record from ACF
    while ( have_rows('dtl') ) : the_row();
      $date = DateTime::createFromFormat('Ymd', get_sub_field('event_date'));
      $dateA = $date->format('Y-m-d');
      $dateB = date('Y-m-d');
    endwhile; 

    // Compare event record from ACF & current date
    if (strtotime($dateA) == strtotime($dateB)) :
        $x= true;
     ?>
        <section class="section-contents"><?php get_template_part( 'templates/events', 'query' ); ?></section>
  <?php endif; // close if strtotime... 
        endwhile;
  ?>
  <?php endif; // close if statement 
  wp_reset_postdata(); 
  if(!$x){ ?>
  <section class="section-contents"> <h5 class="text-center text-danger text-uppercase">No Current Events Set</h5> </section>
  <?php } ?>
