CakePHP submitting forms: link vs post methods

Question

I'd like to obtain some opinions about using link vs post form method types. For example, if I have a controller searches that finds products at the URL /searches/products, there are two ways to make this work.

With the link method, I can grab the data from $this->params['url'] as an array. With post, I can get them in $this->params['form'] using hidden form elements. This is assuming I am not using the CakePHP Form Helper. With the post method, the search string can be an argument for the action, so it seems like the way to go, but when would you ever go with the link method when submitting data?

Answer 1

If it's actually a search, I would almost always go w/ the URL method. It allows people to bookmark their results.
