Wordpress搜索显示空结果的空白页

我必须整理一个自定义搜索，根据用户填写的表单将用户发送到不同的搜索结果页面，搜索也已设置为搜索自定义帖子类型 .

当搜索找到结果时，所有内容都会正确显示，但是当它执行空搜索时，它似乎不会运行content-none.php模板 . 而不是“抱歉，但没有与您的搜索字词匹配 . 请使用其他一些不同的关键字再试一次 . ”它只是一个带页眉和页脚的空白页面 .

例如，您可以转到：http://biozymeconnect.ev-labs.com/reseller/，在第二个输入中使用"tx"进行搜索结果，然后使用随机搜索没有结果的搜索 .

细节：

• 基本主题：下划线

• 框架：Zurb的基金会

使用此代码进行自定义帖子类型搜索更改http://adambalee.com/search-wordpress-by-custom-fields-without-a-plugin/

/**
 * Extend WordPress search to include custom fields
 *
 * http://adambalee.com
 */

/**
 * Join posts and postmeta tables
 *
 * http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_join
 */
function cf_search_join( $join ) {
    global $wpdb;

    if ( is_search() ) {    
        $join .=' LEFT JOIN '.$wpdb->postmeta. ' ON '. $wpdb->posts . '.ID = ' . $wpdb->postmeta . '.post_id ';
    }

    return $join;
}
add_filter('posts_join', 'cf_search_join' );

/**
 * Modify the search query with posts_where
 *
 * http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_where
 */
function cf_search_where( $where ) {
    global $pagenow, $wpdb;

    if ( is_search() ) {
        $where = preg_replace(
            "/\(\s*".$wpdb->posts.".post_title\s+LIKE\s*(\'[^\']+\')\s*\)/",
            "(".$wpdb->posts.".post_title LIKE $1) OR (".$wpdb->postmeta.".meta_value LIKE $1)", $where );
    }

    return $where;
}
add_filter( 'posts_where', 'cf_search_where' );

/**
 * Prevent duplicates
 *
 * http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_distinct
 */
function cf_search_distinct( $where ) {
    global $wpdb;

    if ( is_search() ) {
        return "DISTINCT";
    }

    return $where;
}
add_filter( 'posts_distinct', 'cf_search_distinct' );

要自定义搜索结果，我使用了本教程http://wpgarage.com/code-snippets/how-to-customize-multiple-search-result-pages-in-wordpress/

编辑了search.php

<?php
/* Template Name: Search Results */
$search_refer = $_GET["site_section"];
if ($search_refer == 'reseller') { load_template(TEMPLATEPATH . '/reseller-search.php'); }
elseif ($search_refer == 'site-search') { load_template(TEMPLATEPATH . '/dealer-search.php'); }; ?>

我编辑了reseller-search.php和dealer-search.php .

<?php

 *
 * @link https://developer.wordpress.org/themes/basics/template-hierarchy/#search-result
