SYNOPSIS

   my $e = $form->element( { type => 'Token' } );
   
   my $p = $form->element( { plugin => 'Token' } );
 
 

DESCRIPTION

This field can prevent CSRF attacks. It contains a random token. After submission the token is checked with the token which is stored in the session of the current user. See ``USING TOKENS'' in Catalyst::Controller::HTML::FormFu for a convenient way how to use it.

Value of the stash key for the Catalyst context object ($c). Defaults to "context".

expiration_time

Time to life for a token in seconds. Defaults to 3600.

session_key

Session key which is used to store the tokens. Defaults to "__token".

METHODS

expire_token

This method looks in the session for expired tokens and removes them.

get_token

Generates a new token and stores it in the stash.

remove_token

Removes a specific token from the session. Returns 1 if the key was found. 0 otherwise.

verify_token

Checks whether a given token is already in the session. If it exists it is removed and "verify_token" returns 1. 0 otherwise.
