WooCommerce：预先设置购物车页面上的默认付款方式

I am trying to restrict discounts or coupons if a customer selects a specific payment method. To do this, I have used a plugin called WooCommerce Extended Coupon Features.

I have 3 active payment methods: Cheque, Credit Card & PayPal in respective order. I set a coupon to restrict the discount being applied on the order if the payment method "PayPal" is selected.

However, at the Cart Page when I am adding a coupon to my order, I am getting the current error.

The coupon is not valid for the currently selected payment method.

I thought the default payment method for WooCommerce was to be the first one in sequential order yet it gives me that error. There are ways to programmatically un-apply the default payment method but I have not seen a method to apply it on the Cart page which is before the Checkout page.

I have tried the following:

  $available_gateways = $woocommerce->payment_gateways->get_available_payment_gateways();

  $available_gateways['cheque']->chosen = true;

But that only works for the Checkout page.

Any ideas?

I had the same problem and I solved this way:

in woocommerce-auto-added-coupons/includes/WJECF_Controller.php look for this line:

//============================
    //Test restricted payment methods

and add this code before:

if (!isset( WC()->session->chosen_payment_method ) || WC()->session->chosen_payment_method == '' || !is_checkout()) {WC()->session->set('chosen_payment_method', 'paypal');}
