Php 如何在codeigniter中显示应用于电子商务站点产品的过滤器数量？

我已经在我的站点中为产品添加了一些过滤器（如价格、品牌、类别等），现在我想显示应用了多少个过滤器

这是查看页面：

<div class="btn btn-info" data-toggle="modal" data-target="#myModal"  style="width:130px;">
   <div class="list-updtr__img"></div>
   <div class="list-updtr__lbl" style="font-size:12px;">FILTER BY</div>
   <div class="list-updtr__val" style="font-size: 10px;margin-left: 18px;">0 filters applied</div>
</div>

---

在上面的代码中，我在哪里添加过滤器计数，我需要设置计数需要增加的标志，当应用过滤器时，首先，在实际控制器开始像这样工作之前，您需要声明会话变量

$_SESSION['filters_counter'] = 0;

现在，每当任何用户应用任何过滤器时，只要像这样增加控制器中的

filter\u计数器

变量

if ($this->input->get_post('deal_type')) {
    $this->data['current_deal_type'] = explode('-', $this->input->get_post('deal_type'));
    $filters['deals.deal_type'] = $this->data['current_deal_type'];
    $_SESSION['filters_counter'] += 1;
}
if ($this->input->get_post('tags')) {
    $this->data['current_tags'] = explode('-', $this->input->get_post('tags'));
    $filters['deals.tags'] = $this->data['current_tags'];
    $_SESSION['filters_counter'] += 1;

    $filters['deals.deal_title'] = $this->input->get_post('s');

$filters['deals.deal\u price您可以在会话中存储筛选器计数。@Ropalimunsi我不知道如何计数筛选器的数目每当您在代码中应用任何筛选器时，只需增加会话值。@Ropalimunsi请查看上述代码，您能告诉我在哪里添加筛选器吗session@Prajakta很高兴知道它帮助了你，如果你不介意的话，你可以爬起来投票决定答案。
