How to make protection from flood attack in laravel?

Question

Laravel

There is a button on it hangs the output agent on pressing this button. In the POST ajax request handler.
The problem is that if you have time to click on this button several times, then the request will be sent several times (only 2 requests were always counted).
The request itself makes an entry in the table - it charges money and it turns out that it charges 2 times to the same account. After the request is completed, the status of the account changes to "enrolled" and it cannot be executed anymore, but those 2 times pass.
Is there any solution, for example, to generate a token, but only somehow do it globally for the entire framework - all requests.

Answer 1

1. It is necessary to block the button after the click
2. It is necessary to lock the record in the database before the update (google select for update)
