Placing form inputs into a link_to :method => :post

link_to :method => :post allows me to create a form post that looks like
a link.

Is there a way to add inputs to this form? Basically, I will be posting
this form to another website to perform a search and need to include
some other paramters with the search. Nevertheless, I’d like the whole
thing to look like a link.

Cheers,
Jake
