How do I get the URL var string for a particular taxonomy?

Hello @averixus

Thank you for using Filter Everything plugin.

There are two functions that can help you to find all selected filters on a page ‘flrt_is_filter_request’ and ‘flrt_selected_filter_terms’. The first one gives you information if the current page is filter request, the second gives you all data of selected filters:

if ( function_exists('flrt_is_filter_request') ) {
    if( flrt_is_filter_request() ){
        $selected_fitlers = flrt_selected_filter_terms();
        var_dump( $selected_fitlers );
    }
}

This code will show you something like this:

array(2) {
  ["color"]=>
  array(10) {
    ["entity"]=>
    string(8) "taxonomy"
    ["e_name"]=>
    string(8) "pa_color"
    ["slug"]=>
    string(5) "color"
    ["in_path"]=>
    string(3) "yes"
    ["values"]=>
    array(1) {
      [0]=>
      string(5) "black"
    }
    ["founded_in_path"]=>
    string(3) "yes"
    ["logic"]=>
    string(2) "or"
    ["show_chips"]=>
    string(3) "yes"
    ["label"]=>
    string(5) "Color"
    ["used_for_variations"]=>
    string(3) "yes"
  }
  ["brand"]=>
  array(10) {
    ["entity"]=>
    string(8) "taxonomy"
    ["e_name"]=>
    string(8) "pa_brand"
    ["slug"]=>
    string(5) "brand"
    ["in_path"]=>
    string(3) "yes"
    ["values"]=>
    array(1) {
      [0]=>
      string(5) "apple"
    }
    ["founded_in_path"]=>
    string(3) "yes"
    ["logic"]=>
    string(2) "or"
    ["show_chips"]=>
    string(3) "yes"
    ["label"]=>
    string(5) "Brand"
    ["used_for_variations"]=>
    string(2) "no"
  }
}

Where array keys are filter URL variables.
I hope this will help you.
