您可以使用template_include 过滤器挂钩

add_filter(\'template_include\',\'my_custom_search_template\');

function my_custom_search_template($template){
    global $wp_query;
    if (!$wp_query->is_search)
        return $template;
    
    return dirname( __FILE__ ) . \'/my_search_template.php\';

} /*UPDATE: there was a missing ";" after $template*/
