如何将wordpress循环与网格系统引导程序一起使用？

我想显示一个带两列的条形行，其中包含wordpress循环内容（标题，以绿色块表示），每行都有白色和灰色背景的列，这些列在每行中反转，就像国际象棋检查器一样。

我相信这就是您正在寻找的。这会循环浏览您拥有的所有帖子，然后按照草图的外观对它们进行排序。

<div class='container'>
    <?php
       $args = array(
           'post_type' => 'post' // Get only posts
       );

       $the_query = new WP_Query ( $args ); // build query

       $count = $the_query->post_count; // Check number of posts

   <style>
       .row:nth-child(even) .col-5:nth-child(even) { /* Select every even row and and even post */
           background: #ddd;
       }

       .row:nth-child(odd) .col-5:nth-child(odd) { /*  Select every odd row and odd post*/
           background: #ddd;
       }
   </style>
       <?php
           while ( $the_query -> have_posts() ) : $the_query -> the_post();
               $post_index = $the_query->current_post + 1; // $current_post = gets the post index in loop

               if ( $post_index % 2 != 0 ) { // Open div if post is odd
                    echo '<div class="row" style="border: 2px solid red; padding: 20px; margin:30px;">';
               }

               if ( $post_index % 2 != 0) { // If post is odd then give one class
       ?>                
                   <div class="col-xs-5 <?php echo "post_$post_index" ?>" style="border: 1px solid green;">
                       <h2><?php the_title(); ?></h2>
                       <p><?php the_excerpt(); ?></p>
                   </div>
          <?php
               } else {
          ?>
                   <div class="col-xs-5 col-xs-push-2 <?php echo "post_$post_index" ?>" style="border: 1px solid green;">
                       <h2><?php the_title(); ?></h2>
                       <p><?php the_excerpt(); ?></p>
                   </div>
          <?php } // End if ( $post_index % 2 != 0)

              if ( $post_index % 2 == 0 ) { // Close div if post is even
                  echo "</div>";
              }                      

       endwhile;
       wp_reset_postdata();
   ?>


        </div>
        <!-- /.container -->

原答案

这就是您要寻找的 html。只需更改类名称即可满足您的需要。由于它是 WordPress 循环，因此您必须执行 if else 语句来确定何时开始新行以及何时使用不同的背景颜色。

.row {
  border: 2px solid red;
  padding: 10px 20px;
  margin: 30px 0;
}

.col-xs-5 {
  border: 1px solid green;
  height: 100px;
}

.gray-bg {
  background: #ccc;
}
