Multistep Forms with Lookup Functions that Change Values
Submitted by John on Tue, 2008-01-29 14:40
A number of people lately have been asking about how to change the values of form fields in multistep forms. So I wrote up an example.
Here we have a simple multistep form that lets you enter the name of a U.S. state, such as Iowa. Note the form has a default value.
Then, upon clicking the Lookup button, the value "Iowa" is replaced with a standardized state abbreviation, IA.
Upon submission both values are available to the submit function.
This example is not intended to do anything useful. It's just a little example that you can poke around with to learn how the sometimes confusing multistep form submission works in Drupal 5. You can download the module here.
