How to get the field name?
This is fairly easy. The field name is what goes in the URL when you perform a search. So if I performed a search using categories and tags my URL might look like:
http://www.yoursite.com/?sfid=1526&_sf_s=searchterm&_sft_post_tag=extra-large&_sft_category=shorts
So in this case, the field names for my Category Field and Tag fields are:
_sft_post_tag
_sft_categoryThis is taken from:
http://www.yoursite.com/?sfid=1526&_sf_s=searchterm&_sft_post_tag=extra-large&_sft_category=shorts
