Testing for items in cart

How would I test for the presence of items in the cart? For example I have this in my product display template:

<li><a class="btn  btn--checkout" href="/cart">View Cart</a></li>

Can I do something like this:

<perch:if exists="test-for-items-in-cart">
    <li><a class="btn  btn--checkout" href="/cart">View Cart</a></li>
</perch:if>

Do you want to test for specific items, or just if there's anything at all in the cart?

Hello Winston,

If you want to check whether there's anything in the cart, you can use perch_shop_cart_item_count() to get the number of items in your cart and if there is any, pass a variable into your template.

In your page.php:

$cart_count = perch_shop_cart_item_count([], true); 
if($cart_count) {
    PerchSystem::set_var('items_in_cart', true);
}

And in your template.html:

<perch:if exists="items_in_cart">
    <li><a class="btn btn--checkout" href="/cart">View Cart</a></li>
</perch:if>

Just if theres anything in the cart. I discovered perch_shop_cart_item_count() but wasn't sure how to use that within template files. Thanks for the help.
