Woocommerce 产品已放入购物车

Question

I have this code to show when the product is already in the cart I need it to show the quantity of the product also.

    add_filter( 'woocommerce_product_add_to_cart_text', 'wcpt_modify_add_to_cart_text', 9999, 2 );

function wcpt_modify_add_to_cart_text( $text, $product ) {
    
    // if cart is empty return 'Add to Quote'
    if ( WC()->cart->is_empty() ) return 'Add to Quote';

    // otherwise loop through cart items
    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
        $product_id = apply_filters( 'woocommerce_cart_item_product_id', $cart_item['product_id'], $cart_item, $cart_item_key );
        $qty = $cart_item['quantity'];
        
        // if cart contains current product ID return its quantity
        if ( $product->get_id() == $product_id ) {
            return $qty . ' - Already Added';
        }
    }

    // if the cart is not empty but the product is not in the cart...
    return 'Add to Quote';
}

UPDATED CODE ABOVE UPDATED WITH HOOKS ASWELL The Code Above works wonders thanks to @businessbloomer the only problem now is that I have to refresh the page to see anything

Answer 1

Code is a bit messy, this revised version should work. I added some inline comments to explain each new section:

add_filter( 'woocommerce_product_add_to_cart_text', 'wcpt_modify_add_to_cart_text', 9999, 2 );

function wcpt_modify_add_to_cart_text( $text, $product ) {
    
    // if cart is empty return 'Add to Quote'
    if ( WC()->cart->is_empty() ) return 'Add to Quote';

    // otherwise loop through cart items
    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
        $product_id = apply_filters( 'woocommerce_cart_item_product_id', $cart_item['product_id'], $cart_item, $cart_item_key );
        $qty = $cart_item['quantity'];
        
        // if cart contains current product ID return its quantity
        if ( $product->get_id() == $product_id ) {
            return $qty . ' - Already Added';
        }
    }

    // if cart is not empty but product is not in the cart...
    return 'Add to Quote';
}
