Limiting search results to a specific Category

Hi,

I found this article which is exactly what I need – http://wordpress.org/support/topic/limiting-search-results-to-a-specific-category

I noticed that you said drop a line in the pro support forum to get the hook code so is there any chance I can get that code?

Thanks for your help in advance.

Hey Wayne

Sorry for the late reply – there have been so many support requests recently its easy to miss one – to limit your categories add this to your functions.php :

function filter_results( $query )
{
    global $sf_form_data;
    global $wp_query;
    
    if ( $sf_form_data->is_valid_form() && $query->is_main_query() && !is_admin() )
    {
	$query->set('cat', '-1,-2,-3'); //you can use any query modifications from here - http://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts
    }
}
add_action( 'pre_get_posts', 'filter_results', 21 );

Hopefully this works for you 🙂

In the aforementioned post, you mention adding that code to “functions.php”. I am not finding that file in the search-filter-pro plugin directory, and I am a bit hesitant to add it anywhere else. Can you clarify where to put it?

In general my use case is that I have two pages: one for movie reviews and one for book reviews. On the movie page, I want to search across movie posts. On the book page, I want to search across book posts. I think I can do this by simply limiting the category used in the search to “movie” or “book” — depending on which page the search bar is used. (This might be possible by using the “exclude_ids”, but I would rather include one specific category — a white list instead of a black list.)

I think I’m close to being able to get Search and Filter Pro to be able to do this, but I still can’t get the category aspects functioning correctly. I’d love to apply a search filter that would automatically search on only the category of “movie” or “book” respectively.

Hey Matthew

functions.php is the file you will find in the root of your theme directory – this is a common place to add custom code – let me know if you need further info (http://codex.wordpress.org/Functions_File_Explained)

In 2 weeks I will be able to work full time on Search & Filter again, and at that time you can expect a lot of updates and improvements, and setting up default categories etc is a common request and high on my to do list – so expect this to be integrated in the plugin in the near future!

Thanks
