How to acces a fields.char value before the pay now button is clicked on a e-commerce site

Question

Hi, for the plugin i am working on, i need to access the value of one of my fields before the user has click on the "pay now" button.
With my test, i have come to the conclusion that all of my fields i have put in the payment_provider files value are only updated after the order has been created.
What i mean is that when i try to acces the value of my fields on the "/shop/payment" page, i get "False". When i get them after i have clicked on the button i get the value intended.

Is there anyway t

So i found a solution :
In the function
_prepareInlineForm
from the payment_form_mixin.js, get the paymentOptionId argument into your python.
Then with "
request.env['payment.provider'].sudo().browse(paymentOptionId).exists()" you can create an access to your variable and get them like this
request.env['payment.provider'].sudo().browse(provider_id).exists().My_variable
