创建了一个非常简单的插件来显示自定义搜索表单。无错误，但不执行搜索。我可能有些不知所措，遗漏了一个或多个要求。

我的插件代码：

/**
 * Begin Shortcode.
 */
function divilicious_micro_search($atts, $content = null) {
   extract(shortcode_atts(array(\'color\' => \'teal\'), $atts));

   return \'<div id="dlms">
            <form role="search" method="get" action="\' . home_url( \'/\' ) . \'"  class="dlms">
              <input type="search" class="dlms-search-input" placeholder="\'.esc_attr__(\'Search...\',\'dlms\').\'" value="\'.get_search_query().\'" name="s" title="Search for:" >
              \'.get_search_query().\'
              <button style="background:\'.$color.\'" type="submit">
                <span class="fontawesome-search"></span>
              </button>
            </form>
        </div>\';
}

add_shortcode(\'dl-micro-search\', \'divilicious_micro_search\');
