Limit Results to Specific Category

Do you mean the default category or custom taxonomy?

Category. I’d like the results to pull from a specific post type (already done) AND category.

For example my custom post type is “listings” and it uses the default categories. I want my search results to only show listing post from a specific category (say for example “lodging”)

I would like to do this per form, so that I can make more than one search form that searches different categories/post types.

Hello, i’m also interested in an answer.

Actually i’m using this system and i need the category ID to be send within the form.

For example when i’m on a specific category the GET value of “cat” is 53

( ?cat=53 )

And when i press search on the form in this specific category, the search is done but “cat” value doesn’t exist anymore in the new page.

I don’t know if such a thing already exist in your plugin ?

You can inject ‘category__not_in‘ parameter to the argument filter.

Depends on the result template, if it is default template, you should use uwpqsf_deftemp_query() filter. If Ajax, use wpqsf_query_args().

Example of use:

add_filter('wpqsf_query_args','exclude_cat_uwpqsf','', 3);
function exclude_cat_uwpqsf($args, $id,$getdata){
  $args['category__not_in'] = array(53,12,45);
  return $args;
}

Not sure I follow, how do I use category_not_in to specify which category the search form uses?

You can use the form id ($id) for conditional check.

Eg.

function exclude_cat_uwpqsf($args, $id,$getdata){
 if($id == '123') //123 is your form id{
  $args['category__not_in'] = array(53,12,45);}
 if($id=='234'){
     $args['category__not_in'] = array(1,2,35);
   }
  return $args;
}
