form_for being submitting by 2 links, how to I tell which was used when I am back in the controller?

Question

I putting a form together, but for design reason the form must be submitted by a link. I found out how to perform that:

= link_to_function \"Next >>\", \"$         


        

Answer 1

= link_to_function "Next >>", "$('#hidden_field').value = 1;$(this).up('form').submit()"
= link_to_function "Next 2 >>", "$('#hidden_field').value = 2;$(this).up('form').submit()"

Assuming you're using jquery, set a hidden field to different values depending on which link was clicked. The 2nd parameter to link_to_function is merely javascript, after all.
