WooCommerce：类别产品循环奇怪的问题

  很难从你的图像中看出，但我几乎是100％你没有正确关闭表标签，你所描述的正是在这种情况下会发生什么 .

  问题是你在一个迭代点（foreach）上打开一个表标记，然后在下一个迭代点添加2行，ok，到目前为止，在open table标记内添加一个h2标记，依此类推 .

  浏览器将尝试通过关闭标记为您修复这些标记，但它不会为您重新排列html，因此h标记在渲染视图中的表格上方可见 .

  见下文：只有有帖子才会打开表格 . 如果你想在没有帖子时打开一个，你需要在宣布“找不到帖子”等之前关闭 table

  <?php
  
  $args2 = array( 'taxonomy'  =>   'product_cat', 'parent' => 9 );
  $sub_cats = get_categories( $args2 );
  
  foreach( $sub_cats as $sub_category ) { ?>
  
      <div class="treatments-description col-md-9" id="<?php echo $sub_category->term_id;?>">
  
          <h2 class="section-heading">
              <span class="line-behind-text"><?php echo $sub_category->name;?></span>
          </h2>
  
          <p class="section-text">
              OPIS: <?php echo category_description(); ?> //this part does not work too, not sure why
          </p>
  
          <h3 class="section-heading"><p class="line-behind-text">Dostepne zabiegi</p></h3>
          <?php
  
              $name = $sub_category->name;
              $args = array( 'post_type' => 'product', 
                             "product_cat" => $sub_category->term_id //PROBLEM HERE
                      );
  
               $loop = new WP_Query( $args );
  
               if ( $loop->have_posts() ) {
                  //only include the table if we have posts???
  
                      echo '<table class="treatments-table table products">';
  
                      echo '<tr class="table-heading">

                   while ( $loop->have_posts() ) : $loop->the_post();
  
                       $product = new WC_Product(get_the_ID()); ?>

                           <td><button class="button-product materialbutton">Rezerwuj</button> </td>

                  echo '</table>'; 
  
  
               } 
               else {
  
                   echo __( 'No products found' );
               } ?>
  
               <h1>THE END</h1> <?php
  } //ALL UNCLOSED TAGS ARE GETTING CLOSED AFTERWARDS -- must close tags in the loop, otherwise multiple open tags!!

  • 对于您的第一个问题，我很确定您需要将 category_description(); 替换为 $sub_category->description; （在下面的代码中是 $sub_cat->description; ）

  • 对于你的第二个问题，我无法测试它，我不完全确定，但你需要更多的东西（ see in here ）......

  • 您还需要使用 </table> （接近结尾）和 </div> （结尾）关闭表格

  <?php
  
      $args2 = array( 'taxonomy'  =>   'product_cat', 'parent' => 9 );
      $sub_cats = get_categories( $args2 );
  
      foreach( $sub_cats as $sub_cat ) { ?>
          $sub_cat_name = $sub_cat->name;
          $sub_cat_description = $sub_cat->description; // <= Here (1)
          $sub_cat_id = $sub_cat->term_id;
  
      <div class="treatments-description col-md-9" id="<?php echo $sub_category->term_id;?>">
  
          <h2 class="section-heading">
              <span class="line-behind-text"><?php echo $sub_cat_name; ?></span>
          </h2>
  
          <p class="section-text">
              OPIS: <?php echo $sub_cat_description; ?>
          </p>
  
          <h3 class="section-heading"><p class="line-behind-text">Dostępne zabiegi</p></h3>
  
          <table class="treatments-table table products">
  
              <tr class="table-heading">

              global $post; // Here (2)
              $terms = get_the_terms( $post->ID, 'product_cat' );
              foreach ($terms as $term) {
                  $product_cat_id = $term->term_id;
                  // $product_cat_name = $term->name;

              $loop = new WP_Query( $args );
  
              if ( $loop->have_posts() ) {
  
                  while ( $loop->have_posts() ) : $loop->the_post();
  
                      $product = new WC_Product(get_the_ID()); ?>

                  endwhile; ?>
          </table>
          <?php

              else {

           <h1>THE END</h1> 
           <?php
           } 
           ?>
       </div>
