So ok. Not nice of us to leave these unanswered. form.valid means that you've run form.validates() and that the form contents are valid. It's a property of the form object. The usage in the article is not very clever. You should test if the fields contains the error messages (if I remember correctly, there should be a notes property on each field), and then display the notes as error messages in your template code. Alternatively, if you're using the form.render() method, this is done automatically for you. The real use case scenario for form.valid would be something else, but I'll leave that up to your imagination. I never needed to do that in templates. > Also what is the significance of the ":" in $:form.render(). As per > the documents it is used to avoid escaping of HTML code.

It automatically escapes any HTML tags to prevent XSS attacks. However, sometimes you do want to output HTML, and that's what colon is for. It must appear right after the $ sign. -- Branko Vukelic [email protected] http://www.brankovukelic.com/ -- You received this message because you are subscribed to the Google Groups "web.py" group.
