What are ColdFusion custom tags and how do I use them?
Custom tags are a way of encapsulating your code so that you can use it on other ColdFusion pages just like a standard CFML tag.
For example, you could create a customer tag called "cf_hello" as follows:
- First, build a page named hello.cfm with the following code:<cfoutput> Hello#Attributes.Name#! </cfoutput>
- Now, build another page called myapp.cfm (and place it in the same directory as hello.cfm) with the following code:<cf_hello Name="Joe User">
Welcome to my Website! - Browse to myapp.cfm and you will see the results:
Hello, Joe User!
Welcome to my Website!
NOTE: If you plan to use your custom tags across multiple ColdFusion pages in several different directories, you are better off calling your tag using <cfmodule>. This way, you won't have to have a copy of your custom tag page in every directory of your site. For example, the following code will call the custom tag in the parent directory:
<cfmodule template="/hello.dfm" Name="Joe User">
Currently, we do not support the creation of mappings, nor the installation of ColdFusion tags in the cffusionCustom Tags directory on the server.
