Hi Remi.
There's an uptade for the function to check if a product is a digital variation of a standard product.
https://gist.github.com/Katamo/10243188

I can confirm this is working! Just at line 54, remove "". So it becomes:

  $is_virtual = get_post_meta( $product_id, '_virtual', true );

@worldsdrream is right, but it wasn't clear to me what the character he was referring to was.

There's a character in there that doesn't render in the view above, but this gist breaks when copy pasted, it appears as

$is_virtual = get_post_meta( $product_id, ' _virtual', true );

which results in no metadata being retrieved.

Hi! I'm not good with code... but I added the above code to the functions.php of a site with WooCommerce, and when I just have a virtual product in my cart, I still see all the address options, phone number etc. I'm probably doing something wrong here ;-) Any ideas?

I have LearnDash installed, and it comes with a new "Course" option in the Product Data / Product Type section:

(as seen in this screenshot)

When I select Course as the product type, the ability for me to check the "Virtual" checkbox disappears.

Since the Course is technically a product that doesn't need to be shipped, how would I make hide the fields in the same way it does with virtual products? I want to hide the shipping fields and such the same way it would if I had selected "Virtual", as seen here:

I'm not sure if it a new function, but why not use the is_virtual() function for the WC_Product_Simple Object ? For instance if you look at https://gist.github.com/mattpramschufer/957039753ea7a0bc3344e2f817304156 I simply have

function woo_cart_has_virtual_product() {
	foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
		if($cart_item['data']->is_virtual()){
			return true;
		}
	}
	return false;
}

mattpramschufer your code works, but I made some improvements for case if we have both product types in a cart
function woo_cart_has_virtual_product() {
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
return $cart_item['data']->is_virtual() ? true : false;
}
return false;
}
