php - Wordpress - working search form with multiple taxonomies

one text

I need help with filtering Woocommerce products by taxonomy terms:

<form method="GET" action="<?php echo esc_url( home_url() ); ?>">
    <input type="hidden" value="product" name="post_type">

    <div class="select-wrap">
        <label>Locations</label>

        <select class="select--field">
            <option selected disabled>Select location</option>

            <?php
            $tax_terms = get_terms( 'location', array( 'hide_empty' => '0' ) );

            foreach ( $tax_terms as $tax_term ) :  
                echo '<option value="' . $tax_term->name . '">' . $tax_term->name . '</option>';   
            endforeach;
            ?>

        </select>
    </div>

    <div class="select-wrap">
        <label>Sport services</label>

        <select class="select--field">
            <option selected disabled>Select sport service</option>

            <?php
            $tax_terms = get_terms( 'sport', array( 'hide_empty' => '0' ) );

            foreach ( $tax_terms as $tax_term ) :  
                echo '<option value="' . $tax_term->name . '">' . $tax_term->name . '</option>';   
            endforeach;
            ?>

        </select>    
    </div>

    <div class="select-wrap">
        <label>Services</label>

        <select class="select--field">
            <option selected disabled>Select service</option>

            <?php
            $tax_terms = get_terms( 'service', array( 'hide_empty' => '0' ) );

            foreach ( $tax_terms as $tax_term ) :  
                echo '<option value="' . $tax_term->name . '">' . $tax_term->name . '</option>';   
            endforeach;
            ?>

        </select> 
    </div>

    <button type="submit" class="search-btn btn--lg">Search</button>
</form> 

Results from this form are products with no selected terms.. example.com/?post_type=product. It doesn't take into account selected terms. I will very appreciate, if someone can help with this. Thanks a lot!
