Form Fields Update Each Other

[redbarron]

Using DWMX and CFMX 7 to build a drill-down application:

I've checked the forums and other sites and need some guidance as to how I can
make my form such that when a value from the first (drop-down) field is
selected, the next form field changes to reflect the choice made in the first
one, and then again to a third drop-down field. The queries are fairly
straight-forward, but I'm thinking that I need to get the code/query on the
second and third fields to recognized the choices from the previous fields.
How to do that....? Thanks in advance.:confused;

Are they all dropdown/select fields? Try CF_3SelectsRelated, a neat custom tag that does all the heavy lifting for you.

HTH,

Yes, all 3 will be drop-downs. I've looked at CFAjax, but the code is more
than I need or have time to figure out. How would I use that tag (sorry, still
a bit new to CF)? Thanks for your quick reply!

Ok, I did a quick review of Custom Tags. Is the "3SelectsRelated" tag something you've devised, or is that something availabe in CFMX 7 (Custom Tags directory)? Thanks again for the help with this.

Sorry, Red, the correct name is CF_ThreeSelectsRelated, and you should be able to find it in the Developers' Exchange.

Philh,

Thanks again...I got the zip and will try to implement it. I used the
ThreeSelectsRelated name without the cf_ because isn't that the name of the cfm
page when you create a custom tag (and you add the cf_ only on the page that
calls the custom tag)? Anyway, thanks for the help!
