如何使用购物车会话Codeigniter删除项目

Question

I am currently developing an ecommerce system and I am already in the part of ordering module. I am using the shopping cart of Codeigniter and it is my first to do it.

Done in a part of add to cart but having problem in remove single item in cart session. When I clicked the Remove, everything in my cart will be remove.

Question: How can I remove a single item in my cart?

View

<?php foreach ($this->cart->contents() as $items): ?>
        <tr>
              <td><?= $items['name']?></td>
              <td><?= $items['qty']?></td>
              <td style="text-align:center"><span>&#8369;<?= $this->cart->format_number($items['price'])?></span></td>
              <td style="text-align:center"><span>&#8369;<?= $items['subtotal']?></span></td>
              <td><a href="<?= base_url().'user/remove_cart'?>"><button class="btn btn-primary btn-sm"><i class="fa fa-times" aria-hidden="true"><?= $this->cart->remove($items['rowid'])?>REMOVE</i></button></a></td> 
        </tr>
<?php endforeach; ?>

Controller

public function remove_cart($rowid)
    {
        $removed_cart = array(
            'rowid'         => $rowid,
            'qty'           => 0
        );
         $this->cart->update($removed_cart);
    }
}

Answer 1

This code removes the cart items

<td><a href="<?= base_url().'user/remove_cart'?>"><button class="btn btn-primary btn-sm"><i class="fa fa-times" aria-hidden="true"><?= $this->cart->remove($items['rowid'])?>REMOVE</i></button></a></td>

this part

<?= $this->cart->remove($items['rowid'])?>

Here it gets removed

remove the code and you can try like this.

<td>
      <a href="<?= base_url().'user/remove_cart/'.$items['rowid']; ?>">
          <button class="btn btn-primary btn-sm"><i class="fa fa-times" aria-hidden="true">REMOVE</i></button>
      </a>
