verify form data

[mkauspe]

Sorry, n00b question here. How do I verify form data? i.e. I have an html form
that passes data to my insert statement, I want to verfiy that certain fields
have been filled out on the form and return an error if they aren't. Thanks for
any help!

You can use the 'required' attribute of the fields you want the user to fill out.

<cfform .............. required="yes" message="Please fill out">

This is generally done with a combination of Javascript on the client
side (check out [url]http://www.javascriptkit.com[/url] for lots of samples and
tutorials on form validation) and CF on the server side. Particularly
if a database is involved, you absolutely can't rely on javascript
alone doing everything for you, but it's a good first pass at the
validation.

Also as rmorgan pointed out you use cfform and cfinput with the
required="yes" attribute in your cfinput tags. This essentially writes
the javascript for you on the client side, or if you're using CFMX 7,
there are new options (validateAt) that allow you specify validation on
the client, server, or both.
