Hi karolwebtec89,
Are the inputs in your screenshot already there, or did you add those in manually via PS or just editing HTML?
It is possible to add custom fields underneath a payment gateway. To do it on the “Cash on Delivery” option though, you’ll probably need to override the default method and make your own.
I’d suggest giving this a read: https://docs.woothemes.com/document/payment-gateway-api/, and then looking at how we did this in the Stripe extension: https://github.com/woothemes/woocommerce-gateway-stripe/blob/master/includes/class-wc-gateway-stripe.php#L190
I have a Inputs via javascript. It is a omniva shipping widget.
Ehh, yea that won’t work – not by itself at least. You need to add and save the fields using the payments api.
How I can use payments api?
Requires PHP/WooCommerce knowledge to code: https://docs.woothemes.com/document/payment-gateway-api/
