Scenario:页面显示具有选定“类别”（在分类法中称为主题）的自定义帖子类型（视频）的标题列表。例如，主题为“创意”的视频

Problem如果存在符合条件的标题，则列表将正确显示，但如果没有标题，则页面上不会显示消息“未找到标题”。换句话说，echo语句失败了。

My Code

<?php $subject = $_GET[\'subject\'];

if ($subject=="") $subject = \'creativity\';?><?php /*If there is no value returned then the loop defaults to searching for items beginning with \'Creativity\' since its the first term.*/ ?>
<h2>Video Titles For <span class="colorBlack"><?php echo $subject ?></span></h2> <?php     /*This needs to be outside of the loop*/?>

<?php
$loop = new WP_Query( array( \'post_type\' => \'video\', \'subject\' => $subject,     \'posts_per_page\' => 10 ) ); ?>
<?php if (have_posts() ):?>
    <?php while ( $loop->have_posts() ) : $loop->the_post();?>
                            <div class="glossarybody">
                                <h2><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h2>
                             </div>
            <?php endwhile;
      else: echo \'No Titles Found\';
endif;
 ?>

查看法典，“if-else”的形式如下所示：

<?php
if ( have_posts() ) :
while ( have_posts() ) : the_post();
    // Your loop code
endwhile;
else :
echo wpautop( \'Sorry, no posts were found\' );
endif;
?>

因此，我似乎有正确的语法，由于“if”部分功能正确，我假设它有正确的语法。

如果有人能告诉我哪里出了问题，我将不胜感激。

谢谢

$args=array(
  \'subject\' => $subject,
  \'post_type\' => \'video\',
  \'post_status\' => \'publish\',
  \'posts_per_page\' => 10
);

$videos = get_posts( $args );

$has_video = true;

// Loop through the posts
foreach ($videos as $video) :  setup_postdata($video); ?> 

  // We assume  that all posts have a title.
  if(!empty(get_the_title()) {
    <div class="glossarybody">
      <?php the_title(); ?>   
      <?php the_excerpt(); ?>
    </div>
  } else {
    $has_video = false;   
  }
endforeach; 

if(!$has_video)
  _e(\'Sorry, no posts were found\');
