current_form_number() is from the point of view of $form->process() -
not $form->render().
The reference to javascript makes me suspect that you're trying to use
current_form_number() for the form you're rendering.
Basically, when you render a MultiForm, and the current form-part has
no errors, and there are further forms-parts, render does:
$self->next_form->render()
but this doesn't update current_form_number().
I think you'll need to use a similar logic to figure out which form
you're rendering - something like:
$form_number = $multiform->current_form_number;
if ( $multiform->current_form->submitted_and_valid ) {
$form_number++;
}
To explain in detail the numbers you describe above:
When you first load the MultiForm, it loads form 1, which hasn't yet
been submitted.
current_form_number() == 1
render() displays form 1
User submits form 1 with no errors.
current_form_number() == 1
params() returns data from form 1
render() displays form 2
User submits form 2 with no errors.
current_form_number() == 2
params() returns data from form 2
render() displays form 3
User submits form 3 with no errors - MultiForm is complete.
current_form_number() == 3
params() returns data from form 3
render() display form 3 - though why you'd want to do that, I don't know ;)
Hope this helps,
Carl
