Custom Tags
Custom Tags
ColdFusion custom tags are ColdFusion templates just like any other CFML file but are designed to be reused. Coders can save much time by packaging code that is used frequently or can easily add functionality by using free or inexpensive custom tags. There are two general categories of custom tags, one uses only ColdFusion's CFML code. The other packages C++, Java, or other languages into a custom tag that is used by ColdFusion. We'll cover only CFML based tags in this article. For our discussion we will be using CF_States from www.AspiringGeek.com.

Scope
We all start out learning ColdFusion by outputing variables using CFOUTPUT and some pound signs. A variable with an name like myvariable was passed to the page by a form or a link and output as #myvariable#. By not understanding and using scope, we unwittingly add inefficiencies to our code and overlook a lot of advantages that come with using scopes.

CFPARAM and How to Uncheck a Checkbox
CFPARAM and How to Uncheck a Checkbox
For anyone new to application development, you may be perplexed when you create your form for editing some data that should allow a user to uncheck a checkbox and update a record to a status of not checked. You will sooner or later discover an oddity about HTML forms. HTML forms won't allow you to uncheck like you think you should be able to. If you uncheck the checkbox, the value becomes NULL and the form doesn't bother to pass the field. You will find that ColdFusion does have a simple solution and much more with the CFPARAM tag.
