我正在尝试在存档页面上创建一个搜索框，该页面显示自定义帖子类型。
我按照此指南实现了归档页面上的搜索框：
http://wpsnipp.com/index.php/template/create-multiple-search-templates-for-custom-post-types/
所以我创建了一个搜索。php文件，我在其中输入了以下代码：
<?
/* Template Name: Search Results */
$search_refer = $_GET["post_type"];
if ($search_refer == \'spec-needs-res\') { load_template(TEMPLATEPATH . \'/template_search_spec_needs.php\'); }
else { load_template(TEMPLATEPATH . \'/template_search_default.php\'); };
?>
我已经创建了所需的模板\\u search\\u spec\\u。php文件，我将以下代码（循环）放入其中：
<?php
$args = array( \'post_type\' => \'spec-needs-res\', \'posts_per_page\' => -1, \'s\' => $s, \'paged\' => $paged );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
?>
<div class="span4 spec-needs-list-single">
<div class="spec-needs-title"><?php the_title(); ?></div>
<div><?php the_excerpt(); ?></div>
<div class="plus-btn-spec-needs-cont"><a href="<?php the_permalink(); ?>"><button class="plus-btn-spec-needs">+</button></a></div>
</div>
<?php
endwhile;
wp_reset_query();
?>
我在archive-spec-needs-res.php中添加了此代码
<form id="searchform" action="<?php bloginfo(\'home\'); ?>/" method="get">
<input id="s" maxlength="150" name="s" size="20" type="text" value="" class="txt" />
<input name="post_type" type="hidden" value="spec-needs-res" />
<input id="searchsubmit" class="btn" type="submit" value="Search" />
</form>
这个过程似乎很好，但每次我尝试搜索某个内容时，我都会得到一个空页面，模板会被选中，但我没有帖子，所以我永远不会得到结果。
我已经一步一步地跟着导游走了，有什么建议吗？
使现代化
我注意到，搜索框只在我搜索时给出结果，但没有参数，显然，我得到了所有的帖子，但一旦我输入了参数，我就再也得不到结果了，所以搜索框似乎起作用了，但当我使用关键字搜索自定义帖子时，我就不起作用了。
这是我用“webinar”这个词搜索时得到的URL：
http://www.matrix-test.com/edtech3/?s=webinar&post_type=spec-needs-res
URL是否正确？
我有一个自定义的帖子类型，标题是“Webinar”，另一个标签是“Webinar”，我也把Webinar放在文本中的某个地方。
下面是我用来创建自定义帖子类型的代码：

add_action(\'init\', \'spec_needs_cat_register\');
function spec_needs_cat_register() {
$labels = array(

}
