SetVariable

This function is no longer required in well-formed ColdFusion pages.

Sets a variable in the name parameter to the value of the value parameter.

The new value of the variable.

Dynamic evaluation functions

SetVariable(name, value)

DE, Evaluate, IIf

Before this function is called, the client variable must exist, and the cfapplication tag ClientManagement attribute must be set to "Yes".

You can use direct assignment statements in place of this function to set values of dynamically named variables. To do so, put the dynamically named variable in quotation marks and pound signs (#); for example:

<cfset DynamicVar2 = "ABD"> 
<cfset "#DynamicVar2#" = "Test Value2"> 

Also, the following lines are equivalent:

<cfset "myVar#i#" = myVal>
SetVariable("myVar" & i, myVal)

<h3>SetVariable Example</h3>

<cfif IsDefined("FORM.myVariable")>
<!--- strip out url, client., cgi., session., caller. --->
<!--- This example only lets you set form variables --->
<cfset myName = ReplaceList(FORM.myVariable,
 "url,client,cgi,session,caller", "FORM,FORM,FORM,FORM,FORM")>

<cfset temp = SetVariable(myName, FORM.myValue)>
<cfset varName = myName>
<cfset varNameValue = Evaluate(myName)>
<cfoutput>
   <p>Your variable, #varName#
   <p>The value of #varName# is #varNameValue#
</cfoutput>
</cfif>
