Examples of ColdFusion 9 Script Support

This post is more than 2 years old.

A few weeks ago I posted a simple guide to dealing with features you could not use in ColdFusion 9 script based code. While CF9 went a long way to making the scripting form more powerful, there are still some holes that need patching. One of the things that can be a bit confusing though is figuring out all the new script based forms of tags we've used in the past. While not a deep dive, I decided to write up a quick template that ran through all of these new keywords just so I'd have the syntax handy. I hope this helps.

Doing a dump...
<cfscript> writedump(var=server,top=2,label="You betcha"); </cfscript>

Doing an include...
<cfscript> include "foo.cfm"; //a dynamic version... x = "test2.cfm"; include x; </cfscript>

Doing a cflocation...
<cfscript> location(url="test2.cfm",addtoken=false); </cfscript>

<cfscript> param name="y" default=1 min=1; writeOutput("y is " & y); </cfscript>

Doing a lock...
<cfscript> lock type="exlcusive" name="somelock" timeout="30" { //stuff } </cfscript>

Doing a log...
<cfscript> writelog(file="application", text="beer time?"); </cfscript>

Doing cfsavecontent...
<cfscript> savecontent variable="buffer" { include "test2.cfm"; } </cfscript>

Exception handling...
<cfscript> try { writeoutput("unknown #variablename#"); } catch(any e) { //if(e.errnumber == 0) rethrow; writedump(var=e); } finally { writeoutput("<p>finally...."); } </cfscript>

<cfscript> trace(category="beer",text="my trace"); </cfscript>

<cfscript> thread name="slowthing" priority="low" { sleep(1000); } </cfscript>

<cfscript> transaction action="begin" {


} </cfscript>

Throwing an exception...
<cfscript> throw(message="You smell", detail="No, you REALLY smell"); </cfscript>

Stopping the execution of a request
<cfscript> abort; </cfscript>

I think that covers everything, but if I missed something, let me know.

Shoot - one more just occurred to me. You can set pagencoding for a CFC at the top of the file - but after the component begins, ala:

component car { pageencoding "Cp1252" }

I've yet to use that syntax.

I think the main purpose of ColdFusion is to be a bridge between HTML and the database, so a list of keywords such as this should talk about cfquery vs new query/setSQL. Or you could say it's been replaced by EntityLoad or ORMExecuteQuery.

Comment 2 by Raymond Camden posted on 4/25/2011 at 6:02 PM

I wanted to focus on keywords in the language, not the new components that were built to replace the tag versions.

I would _not_ say ORM has replaced traditional cfquery. It's an option. I'd say - in most cases - I prefer ORM - but the presence of ORM does not mean that normal queries are not used anymore.

Just my two cents. ;)

Would a blog post on the components be useful as well?

You have to ask?
You know, I was just thinking the other day about when I got started in CFML and Raymond Camden was a lone voice in the wilderness. For me, someone who thirsts after ANYTHING related to CF, I am still grateful for every nugget. I remember listening to http://www.helmsandpeters.com/ and perk up when one of them would say "cfset".

I'll whip up some examples. As it stands, I use Snippets in CFB to help me remember the syntax for script based queries. I can't memorize it for some reason.

CFML in 100 minutes has side by side examples of tag versus script. https://github.com/mhenke/C...

@Mike: Nice. I have to admit - I almost didn't click on the .textfile file. I assumed that was some binary format for an app I didn't have. It wasn't obvious at all I could just click and view in the browser.

I'll add that clarification about the textile file in the readme. Also CFML in 100 is also open for anyone to help.

@Mike. Thanks for the link. I was looking for something like this. :)

FINALLY.... Adobe Doc has never been able to capture these clearly.... thanks!

Tried to post cfflush, cfswitch and cfhttp with formfield params, but got flagged as spam.

I think I would die without cfswitch in script these days!

Post a pastebin url. :)

could you add some additional param examples. Namely the version without name value pairs

This was very useful BTW

Comment 14 by Raymond Camden posted on 4/30/2012 at 6:09 PM

Sorry - what? A param w/o name isn't valid. A param w/o a value is just

param name="foo";

Comment 15 by Nathanael Waite posted on 7/29/2014 at 3:50 AM

here is how to call a cfmodule or cftag in cfscript. Comments taken from various other blogs. Hope this save other some time.

module= createObject("java","coldfusion.tagext.lang.ModuleTag");
module.setTemplatePath(expandPath('tagname.cfm')); // cfmodule or cftag location
module.setAttributeCollection({varone="123",vartwo=2,varthree="abc"}); // attributes passed to the tag.

savecontent variable="moduleoutput" {


writeoutput(moduleoutput); // moduleoutput contains tag output

In ColdFusion 11, this is now built in.

Comment 17 by Nathanael Waite posted on 7/29/2014 at 10:49 PM

True but we all don't have CF11 yet :( it takes time to migrate. But good to know.
