Hi Michael

Yup Trevor is correct.

So for the first question 1)

S&F works great with post type archives (you can see this as a display method in display results) but it does not yet fully support taxonomy archives (hence no option).

So, when you submit a search, you will find that S&F redirects to a search results page, as opposed to searching within the current taxonomy archive.

There is 1 workaround which you can do to achieve something similar but you have to do 2 things (and to be honest, you need some coding skills):

a) tell S&F to affect/modify the queries on your taxonomy archives
To do this you need to modify your taxonomy archive query, and attach search_filter_id to the query (this tells S&F it is allowed to change these queries according to filtering selections)… so you will need to use the WP filter pre_get_posts.. something like:

function add_sf_taxonomy_archive( $query ) {
    if ( $query->is_tax("taxonomy_name") && $query->is_main_query() ) {
        $query->set( 'search_filter_id', '1234' );
    }
}
add_action( 'pre_get_posts', 'add_sf_taxonomy_archive');

(replace taxonomy_name with your taxonomy slug, and 1234 with your search form ID)

b) tell S&F which page it should display the results on rather than the default search result page (so, your tax term archive), as
Trevor mentioned you need use our filter to dynamically change this:

function update_sf_url( $url,  $sfid) {
  // Process URL here
  $termname = "termname"; //this needs to by dynamic based on current term
  //this url structure may not be correct for your setup but it will be something similar
  return home_url("/taxonomyname/".$termname ); 
}
add_filter( 'sf_results_url', 'update_sf_url', 10, 2 );
add_filter( 'sf_ajax_results_url', 'update_sf_url', 10, 2 );

The url that is returned needs to point to the current taxonomy term URL, what I wrote above is psuedocode really…

I would also recommend to test the above with Ajax disabled for now, if that works then enable and carry on…

I hope that makes sense, if you are not a programmer though, I would say the above is very very difficult to achieve…

Best

Do you let us know how you get on (and maybe post any code you make that works for you so that others can see and use?). I will leave this thread open waiting for you to confirm if the issue is resolved.
