Menu Missing With Custom Filter

Hi,

I am following the guide at Creating a WP archive with custom field filter.

It’s working great but after filtering, the main menu goes missing. As seen at this link.

The following is the code that I modify

add_action('pre_get_posts', 'my_pre_get_posts');

function my_pre_get_posts( $query){

  //validate
  if (is_admin()){ return; }

  // get original meta query
  $meta_query = $query -> get('meta_query');

  // allow the url to alter the query
  // eg. ?district=1
  // eg. ?district=2
  if (isset($_GET['district']) ){

    $district = $_GET['district'];
    $range = explode(' - ', str_replace('$', '', $_GET['price-range']));

    //add meta query to the original meta queries
    $meta_query[] = array(
        'relation'  => 'AND',
        array(
        'key'       => 'district',
        'value'     => $district,
        'compare'   => 'IN',
        ),
        array(
        'key'       => 'price',
        'value'     => $range[0],
        'type'      => 'NUMERIC',
        'compare'   => '>'
        ),
        array(
        'key'       => 'price',
        'value'     => $range[1],
        'type'      => 'NUMERIC',
        'compare'   => '<'
        )
    );

  }

  // update the meta query args
  $query -> set('meta_query', $meta_query);

  //always return
  return;
}

I read that it is due to is_main_query but I have no idea how to integrate it.

My php skill is alright but I am WordPress amateur.

I have narrowed it down that the district is the problem. When I am filtering without the district the menu appear. Specifically if I remove the district%5B%5D, the menu appear but with it then it will disappear.

Nevermind I found my solution here

I just need to wrap the function with if $query->is_main_query() statement.

 if ($query->is_main_query()){
  // get original meta query
  $meta_query = $query -> get('meta_query');

  // allow the url to alter the query
  // eg. ?district=1
  // eg. ?district=2
  if (isset($_GET['district']) ){

    $district = $_GET['district'];
    $range = explode(' - ', str_replace('$', '', $_GET['price-range']));

    //add meta query to the original meta queries
    $meta_query[] = array(
        'relation'  => 'AND',
        array(
        'key'       => 'district',
        'value'     => $district,
        'compare'   => 'IN',
        ),
        array(
        'key'       => 'price',
        'value'     => $range[0],
        'type'      => 'NUMERIC',
        'compare'   => '>'
        ),
        array(
        'key'       => 'price',
        'value'     => $range[1],
        'type'      => 'NUMERIC',
        'compare'   => '<'
        )
    );

  }

  // update the meta query args
  $query -> set('meta_query', $meta_query);

  //always return
  return;
  }
