Wordpress Loop問題

Question

我遇到了在Wordpress中創建自己的搜索循環的問題。我想實現的是，某些情況下，只顯示某些信息：

<?php while (have_posts()) : the_post(); echo '<div>'; ?> 

     <?php if (in_category('property')) { ?> 
      <h3><?php the_title(); ?></h3> 
      <?php the_field('main-image-description'); ?> 
      <span class="launch"> 
       <a href="<?php the_permalink(); ?>" title="<?php printf(esc_attr__('Permalink to %s', 'boilerplate'), the_title_attribute('echo=0')); ?>" rel="bookmark"> 
        <span class="link">click to launch</span> 
        <span class="launch-icon"></span> 
       </a> 
      </span> 
     <?php } ?> 

     <?php if (in_category('all-developments')) { ?> 
      <h3><?php the_title(); ?></h3> 
      <?php the_field('property-description'); ?> 
      <span class="launch-brochure"> 
       <a href="<?php the_field('pdf-download-all-developments'); ?>" target="_blank"> 
        <span class="link">Download Brochure</span> 
        <span class="launch-icon"></span> 
       </a> 
      </span> 
     <?php } ?> 

     <?php if (is_page()) { ?> 
      <h3><?php the_title(); ?></h3> 
      <?php the_content(); ?> 
      <span class="launch"> 
       <a href="<?php the_permalink(); ?>" title="<?php printf(esc_attr__('Permalink to %s', 'boilerplate'), the_title_attribute('echo=0')); ?>" rel="bookmark"> 
        <span class="link">click to launch</span> 
        <span class="launch-icon"></span> 
       </a> 
      </span> 
     <?php } ?> 

    <?php echo '</div>'; endwhile; ?> 

即出現的問題，是永遠呈現在最上面的一個或兩個空標籤，這廢墟它的風格，每個div都有一個虛線邊框。有沒有告訴Wordpress如果不符合這些條件的方法，那麼不要顯示<div>？

在此先感謝您的幫助！

你能只移動條件語句裏面<div>？像這樣：

<?php while (have_posts()) : the_post(); ?> 

    <?php if (in_category('property')) { ?> 
     <div> <!-- Open div here !--> 
     <h3><?php the_title(); ?></h3> 
     <?php the_field('main-image-description'); ?> 
     <span class="launch"> 
      <a href="<?php the_permalink(); ?>" title="<?php printf(esc_attr__('Permalink to %s', 'boilerplate'), the_title_attribute('echo=0')); ?>" rel="bookmark"> 
       <span class="link">click to launch</span> 
       <span class="launch-icon"></span> 
      </a> 
     </span> 
     </div> <!-- Close div here !--> 
    <?php } ?> 

    <?php if (in_category('all-developments')) { ?> 
     <div> <!-- Open div here !--> 
     <h3><?php the_title(); ?></h3> 
     <?php the_field('property-description'); ?> 
     <span class="launch-brochure"> 
      <a href="<?php the_field('pdf-download-all-developments'); ?>" target="_blank"> 
       <span class="link">Download Brochure</span> 
       <span class="launch-icon"></span> 
      </a> 
     </span> 
     </div> <!-- Close div here !--> 
    <?php } ?> 

    <?php if (is_page()) { ?> 
     <div> <!-- Open div here !--> 
     <h3><?php the_title(); ?></h3> 
     <?php the_content(); ?> 
     <span class="launch"> 
      <a href="<?php the_permalink(); ?>" title="<?php printf(esc_attr__('Permalink to %s', 'boilerplate'), the_title_attribute('echo=0')); ?>" rel="bookmark"> 
       <span class="link">click to launch</span> 
       <span class="launch-icon"></span> 
      </a> 
     </span> 
     </div> <!-- Close div here !--> 
    <?php } ?> 

<?php endwhile; ?>

重新安排你的代碼，以便您在輸出之前計算的條件，像這樣的內容：

<?php 
    while (have_posts()) : the_post(); 

    $propertyCategory  = in_category('property'); 
    $allDevelopmentsCategory = in_category('all-developments'); 
    $isPage     = is_page(); 

    $output = ($propertyCategory || $allDevelopmentsCategory || $isPage); 

    if($output){ 
     echo '<div>'; 
    } 


?> 

    <?php if ($propertyCategory) { ?> 
     <h3><?php the_title(); ?></h3> 
     <?php the_field('main-image-description'); ?> 
     <span class="launch"> 
      <a href="<?php the_permalink(); ?>" title="<?php printf(esc_attr__('Permalink to %s', 'boilerplate'), the_title_attribute('echo=0')); ?>" rel="bookmark"> 
       <span class="link">click to launch</span> 
       <span class="launch-icon"></span> 
      </a> 
     </span> 
    <?php } ?> 

    <?php if ($allDevelopmentsCategory) { ?> 
     <h3><?php the_title(); ?></h3> 
     <?php the_field('property-description'); ?> 
     <span class="launch-brochure"> 
      <a href="<?php the_field('pdf-download-all-developments'); ?>" target="_blank"> 
       <span class="link">Download Brochure</span> 
       <span class="launch-icon"></span> 
      </a> 
     </span> 
    <?php } ?> 

    <?php if ($isPage) { ?> 
     <h3><?php the_title(); ?></h3> 
     <?php the_content(); ?> 
     <span class="launch"> 
      <a href="<?php the_permalink(); ?>" title="<?php printf(esc_attr__('Permalink to %s', 'boilerplate'), the_title_attribute('echo=0')); ?>" rel="bookmark"> 
       <span class="link">click to launch</span> 
       <span class="launch-icon"></span> 
      </a> 
     </span> 
    <?php } ?> 

    <?php 
    if($output){ 
     echo '</div>'; 
    } 

    endwhile; 
?> 

這使您可以檢測是否有任何將被輸出，然後使用div酌情。
