Hi,

I have created my own module, in this i have input form on which, depends on the manufacturer selected from 1st drop down i have to fill up the model(2nd) drop down. I did it using AJAX, not an issue. But when i submit the form, i am getting "An illegal choice has been detected. Please contact the site administrator." error.

I had the same problem with Drupal5, but i used DENGEROUS SKIP CHECK and i was through it,
But for Drupal 6, i am not getting what to do.

Please help
Thanks in advance

Are you creating the form yourself or are you using hook_form_alter() or what?

Easiest Solution: add the second select dropdown option when the form is first created, and then hide it. Make sure every possible option is there. From there, do what you've been doing.

Best Solution: load up the form that is cached during the AJAX call, change the select options, and recache the form. I have done this with AHAH before. Here is an example: http://www.nicklewis.org/node/967

yes, am creating the form myself.

When the form initially loaded, I had sql that fetch and fill the Manufacturer dropdown. and 2nd dropdown(model) is there but dont have options in it.
Now on select on 1st dropdown i called ajax to fill up the Model dropdown, till this its working fine. But when i submit the form am getting "An illegal choice has been detected".

Please suggest in this case what i have to do.

Look at my previous response. You need to do one of the two options:

use
'#validated' => TRUE
for the select element. I have been looking for it for a long time and it works.
NOTE, when you added it, empty cache first.
