We talked about using return parameter with the entry_id redirection in the EE forums: http://expressionengine.com/forums/viewthread/166104/

This works for next buttons, how do you do prev buttons?

I could paginate the form with jQuery accordion, but I would like to save it along the way instead of at the end because it is such a long form. Is this the right approach or does it matter?

I’d do a prev button in the same way.

But the return parameter is specified for the whole form, you can’t have 2.

I was just thinking of using a straight link.

<a href="{path=form/page_1/{entry_id}">Prev</a> 

Or something like that. I suppose that the PREV button wouldn’t submit the data though. I knew we’d used PREV buttons somehwere, but when I went to check it out, it had the same limitation.

<a href="{path='client/payment/{segment_3}'}" class="prev_bttn">Previous</a>
<button id="checkout_next" class="next_bttn">Next</button>

{/exp:cartthrob:checkout_form} 

I suppose you could use jquery to change the return value on the fly when the previous button is pressed. You could have a prev button change the return value, AND submit the form after that. 

<input type="hidden" name="return_url" value="safecracker/ENTRY_ID" />
<input type="hidden" name="return" value="safecracker/ENTRY_ID" />

Here’s a jQuery snippet that might help someone out to change the value attributes of the hidden input fields when the previous button is clicked.

$('#prev').click(function() {
            $("input[name~=return_url]").attr('value', 'case-evaluation/step6/ENTRY_ID');
            $("input[name~=return]").attr('value', 'case-evaluation/step6/ENTRY_ID');
        });
