How to filter custom post type by multiple Taxonomies

On the project there is a filter:

enter image description here

It should filter the custom post ty recipes. Selected items are checkboxes. So, several values for filtering can be selected at any time. But in my case, filtering works only on one selected element. For example, I chose ‘Lorem inpus1’ the recipes were filtered by it. Now I choose any other element ‘Lorem inpus3’ for example and previous results removed. Here is my code. I think the reason is in it, but I cannot solve this issue.

add_action('wp_ajax_myfilter', 'vicso_filter_function'); // wp_ajax_{ACTION HERE}
add_action('wp_ajax_nopriv_myfilter', 'vicso_filter_function');

function vicso_filter_function(){
   //I think problem is here all every time when I make a selection, the function takes a new value
   $products_filter = $_POST['products'];
   $types_food_filter = $_POST['types_food'];

   if( isset( $products_filter ) && !empty( $products_filter) ){
    $products_data = array(
        'taxonomy' => 'products',
        'terms' => $products_filter

 } else{
    $products_filter = '';

 if( isset(  $types_food_filter ) && !empty(  $types_food_filter ) ){
    $types_food_data = array(
        'taxonomy' => 'types_food',
        'terms' =>  $types_food_filter
  } else{
    $types_food_filter = '';

  $args = array (
    'post_type' => 'recipes',
    'posts_per_page' => -1,
    'order' => 'DESC',
    'tax_query' => array(

  $recipes = new WP_Query( $args );


I don’t think the reason could be the javascript code, but here is the code that I call the function above.


let filter = $('#recipes-filter');

return false;
