Subtotal cart variable php WooCommerce

Question

Does anyone know what $variable to use in php to get the subtotal of the cart?
Subtotal = total value of cart BEFORE discount or taxes.

It would help me a lot. I want to add an extra fee if the subtotal is above 250 euro.

Thanks in advance.

Answer 1

I kept getting an incorrect subtotal (a little high, but could not determine why) using Loic's code snippets. I tried every similar variant and eventually found the following code:

WC()->cart->get_subtotal();

Using this snippet above, I get precisely the amount expected which matches the actual subtotal displayed in the cart.

Now my 'free shipping' upsell calculation is working perfectly.
