Re: [Cppcms-users] form validation

[Rodrigo E. <rod...@gm...>]

Hi Mawan,

I don't have yet a complete knowledge about the api of CppCms. But I use it
in very simple form. When you have a validation error in an element (aka: a
subclass of cppcms::widgets::base_widget), the state of this element become
invalid. This invalidity may occur in a manual validation overloading of
the validate() method, or automatic validation, when you use   a method
like cppcms::widgets::base_widget::base_text.non_empty(), and the element
is submited blank.
In the view you can access the method cppcms::base_form.valid() of
cppcms::widgets::base_widget like that:

<% if not form.name.valid() %>
    Message error here
<% end %>

I hope that could be  useful for your doubt and sorry about my English.
