使用分类过滤自定义帖子 - 添加所有按钮

问题描述

我正在通过分类法设置带有前台显示过滤器的自定义帖子。经过几个小时的研究和测试，我终于得到了我想要的东西，但我仍然有两个小东西让我卡住了......如果我们点击，我希望添加一个 ALL 按钮来重新显示我的所有档案之前在另一个过滤器上。 当我的过滤器按钮被激活时，我也无法向我的过滤器按钮添加一个类......你有线索可以推荐我吗？ 下面是我所做的：

archive-work.PHP

<div id="work-filter" class="col-md-12">
<?PHP get_work_filters(); ?>
</div>
<div class="work-results animated fadeIn">
<?PHP $res = my_get_posts();
echo $res['response']; ?>
</div>

functions.PHP

/***************** filter work ****************/
function ajax_filter_posts_scripts() {
  // Enqueue script
  wp_register_script('afp_script',get_template_directory_uri() . 
      '/assets/js/work.js',false,null,false);
  wp_enqueue_script('afp_script');

  wp_localize_script( 'afp_script','afp_vars',array(
        'afp_nonce' => wp_create_nonce( 'afp_nonce' ),// Create nonce which we later will use to verify AJAX request
        'afp_ajax_url' => admin_url( 'admin-ajax.PHP' ),)
  );
}
add_action('wp_enqueue_scripts','ajax_filter_posts_scripts',100);

$result = array();

// Script for getting posts
function ajax_filter_get_posts( $work_item ) {

      // Verify nonce
      if( !isset( $_POST['afp_nonce'] ) || 
          !wp_verify_nonce( $_POST['afp_nonce'],'afp_nonce' ))
        die('Permission denied');

         $work_item = $_POST['expertises'];
         $result = json_encode(my_get_posts($work_item,true));
         echo $result;

         die();

    }
