Custom tag variables
Any ColdFusion custom tag returns the following variables:
ThisTag
.ExecutionMode
ThisTag
.HasEndTag
ThisTag
.GeneratedContent
ThisTag
.AssocAttribs[
index
]
A custom tag can also set a Caller variable to provide infor-
mation to the caller. The Caller variable is set as follows:
<CFSET Caller.
variable_name
= "value">
The calling page can access the variable with the <CFOUT-
PUT> tag:
<CFOUTPUT>#Caller.
variable_name
#</CFOUTPUT>
Request variable
Request variables store data that pertains to the processing
of a single page request. Request variables allow you to store
data in a structure that can be passed to nested tags, such as
Custom Tags, and processed once.
Set a Request variable to provide information to nested tags.
The Request variable is set as follows:
<CFSET Request.
field_name1
= "value">
<CFSET Request.
field_name2
= "value">
<CFSET Request.
field_name3
= "value">
...
Each nested tag can access the variable with the <CFOUT-
PUT> tag:
<CFOUTPUT>#Request.
field_name1
#</CFOUTPUT>
Form variable
ColdFusion supports the Form variable FieldNames. Field-
Names returns the names of the fields on a form. You can
use it on the action page associated with a form.
