我有一个运行良好的WC插件。 如果信用卡出错，我的操作“woocommerce_checkout_process”将不会再次运行

Question

I have this WC plugin with another payment method... So far, so good... I put all the data and submit my form... So, the action function for "woocommerce_checkout_process" runs and I check if some of my fields are empty or something like that...

Nothing is empty, so the plugin process the payment... Ok, but now the page returns saying my credit card is without funds, so I can retry the payment with another credit card or change my payment method.

Here is the problem... Let's say I'll not change my method... So, I'll use my plugin again with the same payment method. When I click "Pay for Order", my action function for "woocommerce_checkout_process" doesn't run again and I cannot check any blank fields...

Any suggests why this happens and how to resolve?!

Thanks
