=head1 NAME
Vend::Table::Editor -- Interchange do-all HTML table editor
=head1 SYNOPSIS
[table-editor OPTIONS]
[table-editor OPTIONS] TEMPLATE [/table-editor]
=head1 DESCRIPTION
The [table-editor] tag produces an HTML form that edits a database
table or collects values for a "wizard". It is extremely configurable
as to display and characteristics of the widgets used to collect the
input.
The widget types are based on the Interchange C<[display ...]> UserTag,
which in turn is heavily based on the ITL core C<[accessories ...]> tag.
The C<simplest> form of C<[table-editor]> is:
[table-editor table=foo]
A page which contains only that tag will edit the table C<foo>, where
C<foo> is the name of an Interchange table to edit. If no C<foo> table
is C<defined>, then nothing will be displayed.
If the C<mv_metadata> entry "foo" is present, it is used as the
definition for table display, including the fields to edit and labels
for sections of the form. If C<ui_data_fields> is defined, this
cancels fetch of the view and any breaks and labels must be
defined with C<ui_break_before> and C<ui_break_before_label>. More
on the view concept later.
A simple "wizard" can be made with:
[table-editor
wizard=1
ui_wizard_fields="foo bar"
mv_nextpage=wizard2
mv_prevpage=wizard_intro
]
The purpose of a "wizard" is to collect values from the user and
place them in the $Values array. A next page value (option mv_nextpage)
must be defined to give a destination; if mv_prevpage is defined then
a "Back" button is presented to allow paging backward in the wizard.
