Hi
I have created a web form, but what I would like it to do (and I'm not
sure if this is possible with Coldfusion?) is when a user enters their
employee number into a text field without a page refresh it runs a
database lookup and populates other fields in the form with that
employees
It is definitely possible and rather easy using CF (or just plain
javascript) - all you need to do is make an ajax request to a cfc/cfm on
your server passing entered employee number as data/argument, which will
return necessary data based on emp number. You then populate necessary
fields
Hi
We are on CF7, not sure if this restricts the amount of functionality
available to me?
So how would it work - when a user types in their employee number in the
text field how would ajax call a SQL query to lookup the data in the db
table to populate the rest of the fields in the form.

Ian,
on CF7 you do not have the built in CFAJAX stuff, so it simply means you
have to do a little more work using CF + JQuery to make ajax calls.
Here is a quickstart using CF7

You will find plenty more examples on google.
even
This will take some research on your part, and there are thousands of
resources out there on the web. I would suggest using JQuery for this.
Basically, user fills in their userid, hits a button (or something) that
triggers the ajax call back to the server. On the server you have a CFC
with a
Basically the easiest way to do ajax, is the following...
1. download jquery libraries, or in your source code refer to different hosting
of the jquery libraries. jquery fyi, is javascript libraries, that work
cross-browser and make it easier to do things like ajax, and millions of other
Hi Craig et al
Thanks for this
So download JQuery and link to the file on your server

Here is a brief tutorial on writing a CFC (Google is your friend)

You would put your query in a method in the CFC.
You would use the success handler of your ajax call to populate the

Does anyone have a fix for this?
Coldfusion is inserting an html comment before any other markup in a
cfcache'd page. This is fine unless you are using IE. IE will go
into quirks mode if the very first line of the page is not the doctype
declaration. Some have suggested to use cfcontent

No, it doesn't have to be a CFC. You could write a CFM file that
accepts inputs and generates JSON or XML output directly. But CFCs are
preferred

Now I did mention that Flex says it REQUIRES RDS to be enabled in order
to use Flex data services.
This is only required to use the wizards in Flash Builder, just like
you need RDS to do things in CF Builder. Once your code is written,
you can deploy it to servers without RDS enabled.

Way back in the day I was told RDS was horribly insecure and I wrote it
off and never looked back.
Neither RDS nor the CF Administrator should be exposed to untrusted
clients. They're both password protected with no auditing of failed
authentication events.
Dave Watts, CTO, Fig Leaf Software
Dreamweaver aso needs RDS for a lot of its features, but RDS is not
supposedly to be installe don production servers.
If you run CF enterprise, then you can sandbox RDS access and give each user
their own login and limit what folders they have access to.

I wouldn't expect that the delete or truncate would still be running,
but if they are, wrapping all of the cfquery tags in a cftransaction
might help, or wrapping the delete/truncate in a transaction, then
calling the insert in a separate cftransaction?

no data is imported.
You say import, so I suppose you INSERT records from another SELECT.
I also suppose that you have checked if this SELECT actually returns records?
Also, do you have an auto-increment field in this

The import is not being done via SQL. It's reading an excel file then doing
a SQL insert.

I don't have any experience with MySQL, but I've heard that there's a

First, you need to move the Truncate query outside the loop. Otherwise
it is being called on each loop iteration, and erasing any records you
inserted on the previous iteration.
Second, close your table with a /table tag after the /tr

I agree, Dave... once I understood the issue and possibilities
