<CFSET variable_name=expression>

Use the CFSET tag to define a ColdFusion variable. If the variable already exists, CFSET resets it to the specified value.

Arrays

The following example assigns a new array to the variable "months".

<CFSET months=ArrayNew(1)>

This example creates a variable "Array_Length" that resolves to the length of the array "Scores".

<CFSET Array_Length=ArrayLen(Scores)>

This example assigns to index position two in the array "months" the value "February".

<CFSET months[2]="February">

Dynamic variable names

In this example, the variable name is itself a variable.

<CFSET myvariable="current_value">
<CFSET "#myvariable#"=5>

COM objects

In this example, a COM object is created. A CFSET defines a value for each method or property in the COM object interface. The last CFSET creates a variable to store the return value from the COM object's "SendMail" method.

<CFOBJECT ACTION="Create" 
    NAME="Mailer" 
    CLASS="SMTPsvg.Mailer"> 
 
<CFSET MAILER.FromName=form.fromname> 
<CFSET MAILER.RemoteHost=RemoteHost> 
<CFSET MAILER.FromAddress=form.fromemail> 
<CFSET MAILER.AddRecipient("form.fromname", "form.fromemail")> 
<CFSET MAILER.Subject="Testing CFOBJECT"> 
<CFSET MAILER.BodyText="form.msgbody"> 
<CFSET Mailer.SMTPLog="logfile"> 
 
<CFSET success=MAILER.SendMail()> 
 
<CFOUTPUT> #success# </CFOUTPUT>
