没有帖子时，Wordpress循环不显示“ else”

Question

When no posts exist I'm used to seeing the message after the else, and I'm not sure why it's not showing it now?

Code:

<?php
     $args = array( 'post_type' => 'event', 'posts_per_page' => 1, 'post_status' => 'future', 'order' => 'ASC' );
     $loop = new WP_Query( $args );
     if ( have_posts() ) : while ( $loop->have_posts() ) : $loop->the_post();
  ?>
  <div class="event_preview_title"><?php the_title(); ?></div>
  <div class="event_details">
    <div class="event_date"><?php the_time('m/d/y'); ?></div>
    <div class="event_time"><?php the_time('g:i A'); ?></div>
  </div>
  <?php the_post_thumbnail( array(65,65) ); ?>
  <a class="clickthrough" href="<?php bloginfo('wpurl'); ?>/events"></a>
  <?php endwhile; else: ?>

  <?php endif; ?>

Thanks!

Answer 1

You made a special WP_Query , but are checking for the wrong posts

if ( have_posts() )

Should be

if ( $loop->have_posts() )

Answer 2

I'm not exactly sure what happens when you use the weird if/while syntax, but:

endwhile;

I think your endwhile is ending the while loop, and the ; is ending the if statement. I suggest using the standard { and } syntax so this sort of thing will be easier to read:

<?php
    $args = array( 'post_type' => 'event', 'posts_per_page' => 1, 'post_status' => 'future', 'order' => 'ASC' );
    $loop = new WP_Query( $args );
    if (have_posts()) {
        while ( $loop->have_posts() ) {
            $loop->the_post();
?>
  <div class="event_preview_title"><?php the_title(); ?></div>
  <div class="event_details">
    <div class="event_date"><?php the_time('m/d/y'); ?></div>
    <div class="event_time"><?php the_time('g:i A'); ?></div>
  </div>
<?php
            the_post_thumbnail( array(65,65) );
?>
  <a class="clickthrough" href="<?php bloginfo('wpurl'); ?>/events"></a>
<?php
        }
    } else {
?>
