How to get the number of items from the cart in Woocommerce by id?

Question

PHP

Hello.
Tell me how in Woocommerce you can get the number of products in the cart, on the store page, knowing the id of each product.
Have a function

woocommerce_quantity_input( $args = array( 'input_value'   =>  0 ) );

It looks something like

this. At the moment, I am passing 0 to the input field. And I want to transfer the number of goods from the basket. There is a product id.
Those. I'm looking for a function like:

$получить_количество_товаров_в_корзине( $id_товара );

And I want to get this

. I hope I explained it clearly. Thank you all in advance!

Mustafo, thanks for your reply. Here's a function I wrote in case it's useful to someone.

function erd_get_cnt_products( $product_id ) {
    $cart_content = WC()->cart->cart_contents;

    $cnt_products = 0;
    if ( $cart_content ) {
        foreach ( $cart_content as $cart_item ) {
            if ( $cart_item['product_id'] == $product_id ) {
                $cnt_products += $cart_item['quantity'];
            }
        }
    }

    return $cnt_products;
}

Now I call the function like this:

woocommerce_quantity_input( $args = array( 'input_value'   =>  erd_get_cnt_products( $product->id ) ) );

Although it seems to me that in Woocommerce this can be obtained in one line.

Try like this:

global $woocommerce;
$items = $woocommerce->cart->get_cart();

Here, the $items array should contain all the information about the items in the cart. In my field 'quantity' is what you need
