WordPress的自定义字段设置

Question

在我的wordpress主题，我创建像

cp_street，cp_city，cp_mobile_no，cp_company_name

等等一些自定义字段。这是显示在single_ad_listing.php页面和代码是

cp_get_ad_details($post->ID, $cat_id); 

和主题function.php页面代码是

// display all the custom fields on the single ad page, by default they are placed in the list area 
if (! function_exists('cp_get_ad_details')) { 
    function cp_get_ad_details($post_id, $category_id, $location = 'list') { 
     global $wpdb; 

     // see if there's a custom form first based on category id. 
     $form_id = cp_get_form_id($category_id); 

     $post = get_post($post_id); 
     if (! $post) 
      return; 

     // if there's no form id it must mean the default form is being used 
     if (! $form_id) { 

      // get all the custom field labels so we can match the field_name up against the post_meta keys 
      $sql = "SELECT field_label, field_name, field_type FROM $wpdb->cp_ad_fields"; 

     } else { 

      // now we should have the formid so show the form layout based on the category selected 
      $sql = $wpdb->prepare("SELECT f.field_label, f.field_name, f.field_type, m.field_pos FROM $wpdb->cp_ad_fields f " 
       . "INNER JOIN $wpdb->cp_ad_meta m ON f.field_id = m.field_id WHERE m.form_id = %s ORDER BY m.field_pos ASC", $form_id); 

     } 

     $results = $wpdb->get_results($sql); 

     if (! $results) { 
      _e('No ad details found.', APP_TD); 
      return; 
     } 

     // allows to hook before ad details 
     cp_action_before_ad_details($results, $post, $location); 

     foreach ($results as $result) { 

      // external plugins can modify or disable field 
      $result = apply_filters('cp_ad_details_field', $result, $post, $location); 
      if (! $result) 
       continue; 

      $disallow_fields = array('cp_price', 'cp_currency'); 
      if (in_array($result->field_name, $disallow_fields)) 
       continue; 

      $post_meta_val = get_post_meta($post->ID, $result->field_name, true); 
      if (empty($post_meta_val)) 
       continue; 

      if ($location == 'list') { 
       if ($result->field_type == 'text area') 
        continue; 

       if ($result->field_type == 'checkbox') { 
        $post_meta_val = get_post_meta($post->ID, $result->field_name, false); 
        $post_meta_val = implode(", ", $post_meta_val); 
       } 

       $args = array('value' => $post_meta_val, 'label' => $result->field_label, 'id' => $result->field_name, 'class' => ''); 
       $args = apply_filters('cp_ad_details_' . $result->field_name, $args, $result, $post, $location); 

       if ($args) 
        echo '<li id="' . $args['id'] . '" class="' . $args['class'] . '"><span>' . esc_html(translate($args['label'], APP_TD)) . ':</span> ' . appthemes_make_clickable($args['value']) . '</li>'; 

      } elseif ($location == 'content') { 
       if ($result->field_type != 'text area') 
        continue; 

       $args = array('value' => $post_meta_val, 'label' => $result->field_label, 'id' => $result->field_name, 'class' => 'custom-text-area dotted'); 
       $args = apply_filters('cp_ad_details_' . $result->field_name, $args, $result, $post, $location); 

       if ($args) 
        echo '<div id="' . $args['id'] . '" class="' . $args['class'] . '"><h3>' . esc_html(translate($args['label'], APP_TD)) . '</h3> ' . appthemes_make_clickable($args['value']) . '</div>'; 

      } 
     } 

所有字段显示顺序，但我想喜欢的地址cp_street, cp_city顶部的页面和手机号码（cp_mobile_no）的页面右侧和其他字段显示相同的地方。

请帮我...
