Back and cash pending

Hello,

The default function on pay on arrival and bank transfer is to auto-block the dates as you know and this is not what I want, because someone can go to the website and make orders in a row and other users can’t book other rooms.

I need this schema:
Pay on arrival and bank transfer orders should be on hold, the client received a confirmation email and admin also received one and the dates shouldn’t be blocked until admin confirms the booking.

It is not okay to be auto confirmed because someone can make multiple orders and can block the dates.

So what I have achieved in some way cod and bacs set to be on hold by changing on hold on statuses.php but:

A. emails are not triggered and admin doesn’t know that there is a new order only if it manually checks the booking manager.
B. Dates are still blocked even if on backend it appears as pending admin.

I’m also planning to add online payments so confirmation upon payment must be selected.
Many thanks in advance.
