Update WooCommerce Delivery cost with condition

Change Delivery price base on what item in cart

 * Add extra price to shipping for a product
add_filter( 'woocommerce_shipping_method_add_rate_args', 'snippet_charge_shipping_extra_per_product', 100, 2 );
function snippet_charge_shipping_extra_per_product( $args, $shipping_method ) {
	// Check that cart contains a product named "Bananas"
	$contains = false;
	foreach ( WC()->cart->get_cart() as $key => $item ) {
		if ( isset( $item['data'] ) && method_exists( $item['data'], 'get_title' ) && $item['data']->get_title() === "Bananas" ) {
			$contains = true;
	// Check that we are processing Economy Shipping method
	if ( $contains && $shipping_method && $shipping_method->get_title() === "Economy Shipping" ) {
		// Add extra of $ 3 to the shipping method. Extra price is added to $args['cost']
		// Taxes will be calculated from the new price.
		$args['cost'] += 3;

	return $args;

When we work with conditions often need to know different values. To check values at the cart page use the code below

// define the woocommerce_before_cart callback 
function action_woocommerce_before_cart( $wccm_before_checkout ) { 
	foreach ( WC()->cart->get_cart() as $key => $item ) {
		echo '<pre>';
		echo '</pre>';
// add the action 
add_action( 'woocommerce_before_cart', 'action_woocommerce_before_cart', 10, 1 );
