- <H3>CFSET Example</H3>
-
- <P>CFSET allows you to set and reassign values to local or
- global variables within a CF template.
-
- <CFSET NumRecords = GetMessages.RecordCount>
- <P>For example, the variable NumRecords has been declared on
- this template to hold the amount of records returned from
- our query (<CFOUTPUT>#NumRecords#</CFOUTPUT>).
-
- <P>In addition, CFSET can be used to pass variables from other
- pages, such as this example which takes the url parameter
- Test from this link (<a href="cfset.cfm?test=<CFOUTPUT>#URLEncodedFormat("
- hey, you, get off of my cloud")#</CFOUTPUT>">click here</A>) to display
- a message:
- <P><CFIF IsDefined ("url.test") is "True">
- <CFOUTPUT><B><I>#url.test#</I></B></CFOUTPUT>
- <CFELSE>
- <H3>The variable url.test has not been passed from
- another page.</H3>
- </CFIF>
-
- <P>Finally, CFSET can also be used to collect environmental
- variables, such as the time, the ip of the user, or any
- other function or expression possible in Cold Fusion.
-
- <CFSET the_date = #DateFormat(Now())# & " " & #TimeFormat(Now())#>
- <CFSET user_ip = CGI.REMOTE_ADDR>
- <CFSET complex_expr = (23 MOD 12) * 3>
- <CFSET str_example = Reverse(Left(GetMessages.body, 35))>
-
-
- <CFOUTPUT>
- <UL>
- <LI>The date: #the_date#
- <LI>User IP Address: #user_ip#
- <LI>Complex Expression ((23 MOD 12) * 3): #complex_expr#
- <LI>String Manipulation (the first 35 characters of
- the body of the first message in our query)
- <BR><B>Reversed</B> :#str_example#
- <BR><B>Normal</B>: #Reverse("#str_example#")#
- </UL>
