Old input without form package?

Question

symfony

How to get the old data of inputs and selects that the User entered before the error was made?
That is, the user entered: email, login, password and its confirmation, clicked confirm, but he got an error by refreshing the page, thereby resetting all the data that he entered earlier.
Although at the same time errors are still displayed to him.

Answer 1

All data that the user enters access to $request.
As a rule, the data from the request is transferred to the form and does not disappear anywhere.$form->handleRequest();
