我的本地系统上有wordpress网站，并且有marketify-child主题，其中搜索项目的搜索框，一切正常，但目前通过帖子名称搜索，我想按标签搜索，我做了它也是主要问题，当我有标签可用时，它会给出正确的结果，如果没有结果，那么它将重定向到404.php，我希望保持在同一页面上没有可用的项目消息。< / strong>
在我的搜索框页面代码
下面 <form role="search" method="get" class="search-form<?php echo '' != get_search_query() ? ' active' : ''; ?>" action="<?php echo esc_url( home_url( '/' ) ); ?>">
