Adding all quantity of a specific lbc_type in cart

问题

i need to add all the quantity of all the product in the cart that have a lbc_type = pouch.

example:

add to cart apple(lbc_type = pouch) user inputted quantity 2
add to cart orange(lbc_type = box) user inputted quantity 2
add to cart grapes(lbc_type = pouch) user inputted quantity 3

so i should get all the product in cart that have lbc_type = pouch then sum up all the quantity which based on the example the overall quantity of lbc_type = pouch is equal to 5. Because apple have quantity 2 and grapes have quantity 3

NOTE: Each product in the product table have column name lbc_type which must contain either Pouch or Box

MY CODES:

foreach($this->cart->contents() as $item)
{
        $name = $item['name']; //product name
        echo "<br>";

        $id = $item['id'];

        print_r($id); //print product_id
        echo " ";

        print_r($name); //print product name
        $data['product'] = $this->PaymentModel->getLBCType($name);
            foreach ($data['product'] as $lbctype) 
            {
                $getLBC = $lbctype->lbc_type;
                    if($getLBC == 'Pouch') //check product if lbc_type pouch
                    {

                        $qty = $item['qty']; //inputted quantity

                        echo " The Quantity of this Product is" .$qty;


                    }
            }

}
        echo "<br/>";  
        //$increment++; 
        die;

Let me try :). First when you add item to cart, you can add any value you define. So use this possibility to store lbc_type:

$data = array(
        'id'      => 'sku_123ABC',
        'qty'     => 1,
        'price'   => 39.95,
        'name'    => 'T-Shirt',
        'lbc_type' => 'Pouch'
);

$this->cart->insert($data);

Then you just simple iterate cart contents:

$pouch_qty = 0;
foreach($this->cart->contents() as $item)
{
    $name = $item['name']; //product name
    echo "<br>";
    $id = $item['id'];
    print_r($id); //print product_id
    echo " ";
    print_r($name); //print product name

    if ($item['lbc_type']=='Pouch') {
       $pouch_qty += $item['qty'];
    }

}
echo "<br/>";
echo " The Quantity of this Product is" .$pouch_qty;
die;
