Wordpress - 如果沒有為單個類別顯示帖子

Question

如果某個類別沒有帖子，我會嘗試顯示一條消息

<?php $recent = new WP_Query("cat=9&showposts=10");
     while($recent->have_posts()) : $recent->the_post();?>
        <?php the_title(); ?>
        <?php the_content();?>
<?php endwhile; ?>

但是當我添加一個“else”時，我得到了空白屏幕

<?php else: ?>
message ////
<?php endif; ?>

Use the following code to get rid of your problem
   <?php
      $recent = new WP_Query("cat=9&showposts=10");
       /*condition for having post*/   
       if ( have_posts() )
        {   
            /*Loop start */
            while($recent->have_posts()) : $recent->the_post();
                 the_title();
                 the_content();
            endwhile;
            /*Loop end*/
        }
         /*No post found to show the following message*/
        else {
                echo  'No Post found';
              }
    ?>

你可以做這樣的事情<?php if ( have_posts() ) { while ( have_posts() ) : the_post(); // Your loop code endwhile; } else { echo 'Sorry, no posts were found'; } ?> <?php if ( have_posts() ) { while ( have_posts() ) : the_post(); // Your loop code endwhile; } else { echo 'Sorry, no posts were found'; } ?>
