=head1 NAME

SL::Form.pm - main data object.

=head1 SYNOPSIS

This is the main data object of kivitendo.
Unfortunately it also acts as a god object for certain data retrieval procedures used in the entry points.
Points of interest for a beginner are:

 - $form->error            - renders a generic error in html. accepts an error message
 - $form->get_standard_dbh - returns a database connection for the

=head1 SPECIAL FUNCTIONS

=head2 C<redirect_header> $url

Generates a HTTP redirection header for the new C<$url>. Constructs an
absolute URL including scheme, host name and port. If C<$url> is a
relative URL then it is considered relative to kivitendo base URL.

This function C<die>s if headers have already been created with
C<$::form-E<gt>header>.

Examples:

  print $::form->redirect_header('oe.pl?action=edit&id=1234');
  print $::form->redirect_header('http://www.lx-office.org/');

=head2 C<header>

Generates a general purpose http/html header and includes most of the scripts
and stylesheets needed. Stylesheets can be added with L<use_stylesheet>.

Only one header will be generated. If the method was already called in this
request it will not output anything and return undef. Also if no
HTTP_USER_AGENT is found, no header is generated.

Although header does not accept parameters itself, it will honor special
hashkeys of its Form instance:

=over 4

=item refresh_time

=item refresh_url

If one of these is set, a http-equiv refresh is generated. Missing parameters
default to 3 seconds and the refering url.

=item stylesheet

Either a scalar or an array ref. Will be inlined into the header. Add
stylesheets with the L<use_stylesheet> function.

=item landscape

If true, a css snippet will be generated that sets the page in landscape mode.

=item favicon

Used to override the default favicon.

=item title

A html page title will be generated from this

=back

=cut
