);DESCRIPTION
This Perl 5 object class is part of a demonstration of CGI::Portable in use. It is one of a set of "application components" that takes its settings and user input through CGI::Portable and uses that class to send its user output. This demo module set can be used together to implement a web site complete with static html pages, e-mail forms, guest books, segmented text document display, usage tracking, and url-forwarding. Of course, true to the intent of CGI::Portable, each of the modules in this demo set can be used independantly of the others.
SYNTAX
This class does not export any functions or methods, so you need to call them using object notation. This means using Class->function() for functions and $object->method() for methods. If you are inheriting this class for your own modules, then that often means something like $self->method().
PUBLIC FUNCTIONS AND METHODS
main( GLOBALS )
You invoke this method to run the application component that is encapsulated by this class. The required argument GLOBALS is an CGI::Portable object that you have previously configured to hold the instance settings and user input for this class. When this method returns then the encapsulated application will have finished and you can get its user output from the CGI::Portable object.
PREFERENCES HANDLED BY THIS MODULE
This POD is coming when I get the time to write it.
custom_fd # if true, we use a custom list of
# questions in the form; otherwise, we simply have a "message" field.
field_defn # instruc for how to make form fields
# If array ref, this is taken literally as list of definitions.
# Otherwise, this is name of a file containing the definitions.
# Field definitions are processed by HTML::FormTemplate, so please see
# its POD to know what options you have in your forms.
fd_in_seqf # if true, above file is of the
# format that is a simplified form of Boulder; else it is Perl code
email_subj # if set, use when sending e-mails
msg_new_title # custom title for new messages
msg_new_head # custom heading for new messagesAUTHOR
