Woocommerce cart page default to one - php

Question

I have my woocommerce page to sell a single product. I need to to go to the cart page with default value of 1 in cart page, so that when users click
www.test.com/cart
it never says "cart is Empty"!
Any ways to do that?
What do I need to do? Any ideas?

Answer 1

It sounds like you want to add a product to the user's cart even if they haven't actually added it themselves:
So that when users click www.test.com/cart it never says "cart is Empty"
For what it's worth, I don't think that's a fantastic idea from a UX point of view (or pretty much any other). However, it is possible.
Be warned: This code is largely untested, and it's triggered to run on init (although it should only run each time the cart is visited). Generally, I would advise against this - but it should do what you want:
function vnm_addThingToCart() {
// Check we're not in admin
if (!is_admin()) {
// Only do this on the cart page
if (is_page('cart')) {
global $woocommerce;
// You're only selling a single product, so let's make sure we're not going to add the same thing over and over
$myProductID = 22; // Or whatever
$productToAdd = get_product($myProductID);
// Make sure the product exists
if ($productToAdd) {
// Make sure there's stock available
$currentStock = $productToAdd->get_stock_quantity();
if ($currentStock > 0) {
// Add the product
$woocommerce->cart->add_to_cart($myProductID);
}
}
}
}
}
add_action('init', 'vnm_addThingToCart');
