WooCommerce: Allow to “Pay for Order” Without Login

Some plugins such as “deposit” and “subscription” payments send customers to the “Pay for Order” page in order to complete a pending WooCommerce order. In certain cases, also, customer is forced to log in and this really affect sales conversion rate – instead of the checkout form customers see this notice: “Please log in to your account below to continue to the payment form“.

Here’s a quick snippet to make sure customers do not have to log in when on the “Pay for Order” page, so that they can immediately go ahead with the payment. The WooCommerce function in question is wc_customer_has_capability, and thankfully we can override this with the user_has_cap filter. Enjoy!
