'1' 数字出现在 wordpress 网站的侧边栏下

Question

下午早些时候，我曾要求解决如何在 Wordpress 的不同类别页面上呼应不同侧边栏的解决方案。现在我面临的问题是所有类别页面的侧边栏下都显示一个连续的“1”。但是，当我切换回在所有类别页面上仅显示一个侧边栏的旧代码时，这并没有发生。这是最初在 sidebar.php 文件中的代码，它在所有页面上只回显一个侧边栏：

<?php  if ( is_active_sidebar( 'main_sidebar' ) ) :  ?>

     <div id="main_sidebar" class="widget-area">
               <?php dynamic_sidebar( 'main_sidebar' ); ?>
     </div><!-- #first_sidebar .widget-area -->

<?php endif; ?>

这是我放在 sidebar.php 文件中的修改后的代码，它在不同类别页面上呼应不同的侧边栏：

<?php  if ( is_active_sidebar( "main_sidebar" ) ) :  ?>

     <div id="main_sidebar" class="widget-area">
               <?php
               if ( is_category( '7' )) {
               echo dynamic_sidebar( 'category_fashion' );
               }
               elseif ( is_category( '1' )) {
               echo dynamic_sidebar( 'category_music' );
               }
               elseif ( is_category( '5' )) {
               echo dynamic_sidebar( 'category_tastemakers' );
               }
               elseif ( is_category( '11' )) {
               echo dynamic_sidebar( 'category_film' );
               }
               elseif ( is_category( '9' )) {
               echo dynamic_sidebar( 'category_model' );
               }
               elseif ( is_category( '6' )) {
               echo dynamic_sidebar( 'category_sports' );
               }
               elseif ( is_category( '8' )) {
               echo dynamic_sidebar( 'category_round' );
               }
               elseif ( is_category( '10' )) {
               echo dynamic_sidebar( 'category_cool' );
               } 
               else 
               {
               echo dynamic_sidebar( 'main_sidebar' );
               }   
               ?>
     </div><!-- #first_sidebar .widget-area -->

<?php endif; ?>

当我使用原始代码时，数字“1”不会出现在侧边栏下方，但是当我切换到我修改过的代码时，数字“1”开始出现在所有页面的侧边栏下方.访问此链接可以看到此行为：http://ignoremusic.com/category/sports/

我还检查了archive.php 文件以及functions.php 文件，但似乎没有任何问题。这是我放在functions.php文件中注册侧边栏的部分代码：

这是与侧边栏相呼应的archives.php文件中的代码：

<div id="sidebar" class="grid_3">
                    <?php get_sidebar(); ?>
            </div><!-- #sidebar-->

我尝试在互联网上搜索问题，但找不到任何东西，所以我期待收到你们的来信。谢谢你。

Answer 1

根据https://codex.wordpress.org/Function_Reference/dynamic_sidebar应该是

dynamic_sidebar( 'category_fashion' );

而不是 echo dynamic_sidebar( 'category_fashion' );
该函数可能返回 true； echo 接受一个字符串； true->string=1，因此附加了1。

Answer 2

多余的echo，由混淆引起，由愚蠢的 Wordpress 函数打印而不是返回它们引起。

在你的情况下，以下是错误的：

<?php echo dynamic_sidebar( 'category_fashion' ); ?>

对比你之前正确的用法：

<?php dynamic_sidebar( 'main_sidebar' ); ?>
