Found a better way:
Only the value name pair of the button you click on gets submitted.
---
elements:
- type: submit
name: submit_next
value: Localized Value + next
- type: submit
name: submit_back
value_loc: Localized Value + back
if ( $form->param( 'submit_next' ) ) {
# go on
}
elsif ( $form->param( 'submit_back' ) ) {
# go back
}
Does the Job pretty good
Thanks anyway!

Thanks - I'm glad it's useful.
But I ran into one problem. I want to use multiple submit buttons. The
common way is, to set a value on each and check that value later to
determine which has been clicked.
That's fine asa long as your page is in only one language.
Could you not do something like:
if ( $form->param( 'submit_1' ), eq $form->loc( 'submit_1' ) ) {
# submit_1 pressed
}
elsif ( $form->param( 'submit_2' ), eq $form->loc( 'submit_2' ) ) {
# submit_2 pressed
}
That's assuming the form is created something like this:
---
elements:
- type: submit
name: submit_1
value_loc: submit_1
- type: submit
name: submit_2
value_loc: submit_2
The only potential problem I think think of with this approach is if:
* you're storing the user's language choice using a session or cookie
* after viewing the page containing the form, but before submitting the form...
* ...the user uses a 2nd browser window to change their language choice
You could prevent this by also storing the language choice in a hidden
field, and then doing $form->languages([ $form->param('lang') ])
before doing the 'eq' checks.
I thought of a hidden field whose value is being changed on submitting
(by JS).
If there is no better way I will write an element for that and publish it.
I'd like to make sure that nothing in the core relies on JS for
functionality - so make sure you pick an appropriate namespace if you
write something like that.
For example, I've created a couple of elements in the
HTML::FormFu::Element::Dojo::* namespace which use the dojo javascript
library (although even these degrade gracefully and are usable without
JS).
See http://html-formfu.googlecode.com/svn/trunk/HTML-FormFu-Dojo/
