WordPress - 自定義訂單功能不起作用

Question

我在這個網站上工作，我在那裏爲產品建立了一個自定義的發佈類型。我想讓客戶決定如何訂購瀏覽類別時顯示的產品。我已經在WordPress默認主題上測試了以下腳本並且它可以工作，但是現在，當我將其移至我自己的主題時，它不起作用。我得到的是一條消息，說沒有帖子找不到。

這裏是我的代碼的外觀：

<?php 

get_header(); 

$order_by = $_GET['order_by']; 
$order = $_GET['order']; 

switch ($order_by) { 
    case 't': 
     $ob = 'title'; 
     break; 

    case 'i': 
     $ob = 'ID'; 
     break; 

    case 'r': 
     $ob = 'rand'; 
     break; 

    default: 
     $ob = 'date'; 
     break; 
} 

switch ($order) { 
    case 'a': 
     $o = 'asc'; 
     break; 

    default: 
     $o = 'desc'; 
     break; 
} 

global $query_string; 
$cat_posts = new WP_Query($query_string.'&orderby='.$ob.'&order='.$o); 

?> 

<?php if ($cat_posts->have_posts()) : ?> 

    <div class="container margin-top"> 

      <div class="row"> 

        <div class="col-md-12 breadcrumbs"> 
         <div class="pull-right bread"> 
          Du er her: 
          <?php if(function_exists('bcn_display')) 
          { 
           bcn_display(); 
          } 
          ?> 
         </div> 
         </div> 

       <div class="col-md-12">

      </div> 

      <div class="row"> 
      <div class="col-md-12">

        <?php 

        while($cat_posts->have_posts()) : $cat_posts->the_post(); 

        ?> 

        <div class="col-md-3 col-sm-6 col-xs-12 pos-box2"> 
         <a href="<?php the_permalink(); ?>"><img src="<?php print_custom_field('primary_img:to_image_src'); ?>" class="img-responsive pos-box-img"></a>

         <?php the_excerpt(); ?> 
         <p><a href="<?php the_permalink(); ?>">Læs mere/rekvirer tilbud</a></p> 
        </div> 

        <?php endwhile; // end of the loop. ?> 

       </div> 
      </div> 
      </div> 

      <div class="row"> 
      <div class="col-md-12">

       $cat = get_query_var('cat'); 
       $categories=get_categories('include='.$cat); 
       if ($categories) { 
        foreach($categories as $category) { 
        echo $category->count . '<span>Produkter i denne kategori</span>'; 
        } 
       } 
       ?> 
      </p> 
       <div class="pull-right" id="pagination"> 
        <?php wp_simple_pagination(); ?> 
       </div> 
       <div class="clearfix"></div> 

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

<?php else: ?> 

<div class="container margin-top"> 

      <div class="row"> 
       <div class="col-md-12"> 
       <div id="productbar" > 
        <h4 id="up"><?php single_cat_title('', true); ?></h4> 
       </div> 
       </div> 
      </div> 

      <div class="row"> 
       <div class="col-md-12">

        <p>Der er ikke blevet tilføjet nogle produkter i denne kategori.</p> 
        </div> 
       </div> 
      </div> 
</div> 

<?php endif; ?> 

<?php get_footer(); ?> 

，這裏是我的代碼看起來如何，當我試圖在默認WordPress主題：

<?php

global $query_string; 

$order_by = $_GET['order_by']; 
$order = $_GET['order']; 

switch ($order_by) { 
    case 't': 
     $ob = 'title'; 
     break; 

    case 'i': 
     $ob = 'ID'; 
     break; 

    case 'r': 
     $ob = 'rand'; 
     break;

     break; 
} 

switch ($order) { 
    case 'a': 
     $o = 'asc'; 
     break; 

    default: 
     $o = 'desc'; 
     break; 
} 

$cat_posts = new WP_Query($query_string.'&orderby='.$ob.'&order='.$o); 
/*LEONIDAS KICKS SOMEONE DOWN A WELL - ALSO THIS IS THE END OF SPARTA */ 

get_header(); ?> 

    <section id="primary" class="content-area">

        */ 
        get_template_part('content', get_post_format()); 

        endwhile; 
        // Previous/next page navigation. 
        twentyfourteen_paging_nav(); 

       else :

Answer 1

的東西，它可以使差哪裏你叫get_header(); - 看看默認的WP主題和你的。 的get_header();應後

$cat_posts = new WP_Query($query_string.'&orderby='.$ob.'&order='.$o);

也將global $query_string;在你的頁面的最開始。
