Checkbox selected by default

Hello

Please read this – https://products-filter.com/manipulate-search-data-options

Thanks for your reply. It does work when the page loads (checkbox selected by default) but then is not possible to deactivate. Stays always checked.

Any clue to solve this?

I used this snippet:

add_filter('woof_get_request_data', 'my_woof_get_request_data');

function my_woof_get_request_data($data){
    $data['stock']='instock';
    return $data;
}

Hello

In this case, use the link to this page with a search query. An example: https://your_site.com/this_page/?swoof=1&stock=instock
