NAME

       HTML::FormFu::Plugin - base class for plugins

   DESCRIPTION
       Plugins can be added to a form or any element to modify their behaviour.  Some plugins should only be added to either a form, or an
       element, depending on their design.

METHODS

       Plugins can override any of the following method stubs.

   process
       Only plugins added to a form or a field element inheriting from HTML::FormFu::Element::_Field will have their "process" method run.

       For form plugins, is called during "process" in HTML::FormFu, before "process" is called on any elements.

       For field plugins, is called during the field's "process" call.

   pre_process
       For form plugins, is called immediately after "pre_process" is run on the elements.

       For element plugins, is called before "pre_process" is run on form plugins.

   post_process
       For form plugins, is called immediately before "process" in HTML::FormFu returns.

       For element plugins, is called before "post_process" is run on form plugins.

   render
       Only plugins added to a form will have their "render" method run.

       Is called during "render" in HTML::FormFu before the "render_method" in HTML::FormFu is called.

   post_render
       Only plugins added to a form will have their "post_render" method run.

       Is called during "render" in HTML::FormFu immediately before "render" in HTML::FormFu return.

       Is passed a reference to the return value of "render_method" in HTML::FormFu.

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 "request_token_enable" 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".

   limit
       Limit the number of tokens which are kept in the session. Defaults to 20.

   constraints
       Defaults to HTML::FormFu::Constraint::RequestToken and HTML::FormFu::Constraint::Required.

   message
       Set the error message.

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.

   verify_token
       Checks whether a given token is already in the session. Returns 1 if it exists, 0 otherwise.
