Chapter 1: ColdFusion Tags

CFSET

Use the CFSET tag to define a ColdFusion variable. If the variable already exists, CFSET
resets it to the specified value.
Syntax
<CFSET variable_name=expression>

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>
