WordPress搜索栏结果空白页

我的博客侧边栏上有一个简单的搜索表单, 该表单仅搜索博客。

< form action="< ?php echo get_site_url() ?> " method="GET"> < input type="search" name="s" placeholder="Click to Search" class="fld-search" required/> < input type="hidden" name="post_type" value="http://www.srcmini.com/post"> < button class="btn-search"> < i class="fa fa-search" aria-hidden="true"> < /i> < /button> < /form>

这是网站网址：http://dev.wonder.lk/blog/
以下是我应用的搜索类型,

博客中可用的值-对于某些值, 它可以提供结果, 但有时它表示未找到。范例：搜寻你好(但你可以在档案库中看到Hello World网志)
搜索其他post_type值-结果是白页, 即使我看不到页眉或页脚。例如：搜索忍者这是产品类型

这些是代码,
search.php

< ?php while ( have_posts() ) : the_post(); if(isset($_GET['post_type'])) { $type = $_GET['post_type']; if($type == 'product') { get_template_part( 'woocommerce/archive', 'product' ); //working fine } else { get_template_part( 'framework/template-parts/page/search', 'post' ); } } else { get_template_part( 'framework/template-parts/page/search', 'post' ); } endwhile; ?>

search-post.php

< ?phpget_header(); //Page Title Bar $pageTitle = 'Search results for: "'.get_search_query().'"'; echo page_title_bar( $pageTitle, get_template_directory_uri().'/framework/assets/images/pg-title-bar.jpg'); ?> < div class="container blog-wrapper page-container"> < div class="row"> < div class="col-lg-9 col-md-9 col-sm-12 col-xs-12"> < ?php if (have_posts()) : while (have_posts()) : the_post(); ?> < ?php // Include Blog Posts List get_template_part('framework/template-parts/post/blog', 'post-list'); ?> < ?php endwhile; ?> < div class="pagination-wrapper"> < ?php pagination(); ?> < /div> < ?php else: ?> < h3> No results found for: '< ?php echo get_search_query(); ?> '< /h3> < ?php endif; ?> < /div> < div class="col-lg-3 col-md-3 col-sm-12 col-xs-12"> < ?php // Include Blog Sidebar get_template_part('framework/template-parts/post/blog', 'sidebar'); ?> < /div> < /div> < /div> < ?php get_footer(); ?>

blog-sidebar和blog-post-list是HTML结构。
问我是否需要更多详细信息。
#1如下更新search.php后, 它工作正常,

< ?phpget_header(); //Page Title Bar $pageTitle = 'Search results for: "'.get_search_query().'"'; echo page_title_bar( $pageTitle, get_template_directory_uri().'/framework/assets/images/pg-title-bar.jpg'); ?> < div class="container blog-wrapper page-container"> < div class="row"> < div class="col-lg-9 col-md-9 col-sm-12 col-xs-12"> < ?php if (have_posts()) : while (have_posts()) : the_post(); ?> < ?php // Include Blog Posts List get_template_part('framework/template-parts/post/blog', 'post-list'); ?> < ?php endwhile; ?> < div class="pagination-wrapper"> < ?php pagination(); ?> < /div> < ?php else: ?> < h3> No results found for: '< ?php echo get_search_query(); ?> '< /h3> < ?php endif; ?> < /div> < div class="col-lg-3 col-md-3 col-sm-12 col-xs-12"> < ?php // Include Blog Sidebar get_template_part('framework/template-parts/post/blog', 'sidebar'); ?> < /div> < /div> < /div> < ?php get_footer(); ?>

如果我得到一个合理且描述清楚的答案, 我可以为该答案提供赏金。
