Check if post belongs to certain category in Woocommerce

I am trying to display prices next to variations on Woocommerce, which I could do just fine. Now instead of showing prices on ALL variations I just want to show prices next to variations belonging to a specific category.

This is what I have come up with so far and logically it makes sense, but not working on this particular category. Any suggestions on how to troubleshoot?

//get prices of variations
    function display_price_in_variation_option_name( $term ) {
    global $wpdb, $product;

    $result = $wpdb->get_col( "SELECT slug FROM {$wpdb->prefix}terms WHERE name = '$term'" );

    $term_slug = ( !empty( $result ) ) ? $result[0] : $term;

    $query = "SELECT postmeta.post_id AS product_id
    FROM {$wpdb->prefix}postmeta AS postmeta
    LEFT JOIN {$wpdb->prefix}posts AS products ON ( products.ID = postmeta.post_id )
    WHERE postmeta.meta_key LIKE 'attribute_%'
    AND postmeta.meta_value = '$term_slug'
    AND products.post_parent = $product->id";

    $variation_id = $wpdb->get_col( $query );

    $parent = wp_get_post_parent_id( $variation_id[0] );

    if ( $parent > 0 ) {
    $_product = new WC_Product_Variation( $variation_id[0] );

    $itemPrice = strip_tags (woocommerce_price( $_product->get_price() ));
    //this is where you can actually customize how the price is displayed
    return $term . ' (' . $itemPrice . ')';
    }
    return $term;

    //Add prices to variations

    global $post;
    $terms = wp_get_post_terms( $post->ID, 'product_cat' );
    foreach ( $terms as $termItem ) $categories[] = $termItem->slug;

    if ( in_array( 'custom-pet-portrait-painting', $categories ) ) {

      add_filter( 'woocommerce_variation_option_name', 'display_price_in_variation_option_name' );

    } //end function

    }

Or can I use get_terms to wrap the below code in which shows the variations price? I pretty much just need to show the prices for variations pertaining to one category.

if (has_term ('my-category', 'product_cat')) {
    //get prices of variations
        function display_price_in_variation_option_name( $term ) {
        global $wpdb, $product;

        $result = $wpdb->get_col( "SELECT slug FROM {$wpdb->prefix}terms WHERE name = '$term'" );

        $term_slug = ( !empty( $result ) ) ? $result[0] : $term;

        $query = "SELECT postmeta.post_id AS product_id
        FROM {$wpdb->prefix}postmeta AS postmeta
        LEFT JOIN {$wpdb->prefix}posts AS products ON ( products.ID = postmeta.post_id )
        WHERE postmeta.meta_key LIKE 'attribute_%'
        AND postmeta.meta_value = '$term_slug'
        AND products.post_parent = $product->id";

        $variation_id = $wpdb->get_col( $query );

        $parent = wp_get_post_parent_id( $variation_id[0] );

        if ( $parent > 0 ) {
        $_product = new WC_Product_Variation( $variation_id[0] );

        $itemPrice = strip_tags (woocommerce_price( $_product->get_price() ));
        //this is where you can actually customize how the price is displayed
        return $term . ' (' . $itemPrice . ')';
        }
        return $term;
    add_filter( 'woocommerce_variation_option_name', 'display_price_in_variation_option_name' );

    } //end has_term
