Add to cart attribute url

The best guide I’ve seen:
https://www.businessbloomer.com/woocommerce-custom-add-cart-urls-ultimate-guide/

It looks like you need the format:
?add-to-cart=88&quantity=1
where 88 is the variation ID, not the product ID.

Yes, it is making additions in that way, but I need to make additions in the format I specified. It works on some websites, but the format I mentioned doesn’t work on my website

function add_product_to_cart_by_slug() {
    if (isset($_GET['add-to-cart'])) {
        $product_slug = sanitize_text_field($_GET['add-to-cart']);

        // Varyasyonlar? yakalamak i?in URL'de "?attribute_pa_" ile ba?layan parametreleri kontrol ediyoruz
        $variation_attributes = array();
        foreach ($_GET as $param => $value) {
            if (strpos($param, 'attribute_pa_') === 0) {
                $attribute = str_replace('attribute_pa_', '', $param);
                $variation_attributes[$attribute] = sanitize_text_field($value);
            }
        }

        $product_args = array(
            'name'             => $product_slug,
            'post_type'        => 'product',
            'posts_per_page'   => 1,
            'post_status'      => 'publish'
        );

        $product_query = new WP_Query($product_args);

        if ($product_query->have_posts()) {
            while ($product_query->have_posts()) {
                $product_query->the_post();
                $product = wc_get_product(get_the_ID());
                $product_id = $product->get_id();

                if ($product->is_type('variable')) {
                    $product_variation_id = find_matching_product_variation($product_id, $variation_attributes);

                    if ($product_variation_id) {
                        WC()->cart->add_to_cart($product_id, 1, $product_variation_id, $variation_attributes);
                        wp_redirect(wc_get_cart_url());
                        exit;
                    } else {
                        // Varyasyon bulunamad?
                        wp_redirect(home_url()); // ?ste?e ba?l? olarak y?nlendirme yapabilirsiniz
                        exit;
                    }
                } else {
                    WC()->cart->add_to_cart($product_id);
                    wp_redirect(wc_get_cart_url());
                    exit;
                }
            }
        }

        wp_reset_postdata();
    }
}
add_action('template_redirect', 'add_product_to_cart_by_slug');

function find_matching_product_variation($product_id, $variation_attributes) {
    $product = wc_get_product($product_id);
    $variations = $product->get_available_variations();

    foreach ($variations as $variation) {
        $variation_data = $variation['attributes'];

        if (array_diff($variation_attributes, $variation_data) === array_diff($variation_data, $variation_attributes)) {
            return $variation['variation_id'];
        }
    }

    return false;
}

I solved the problem by writing a function, guys. If anyone wants to use it, they can add the above code to the functions.php file. We can add items to the cart using the following format: “/?add-to-cart=product-slug&attribute_pa_variation=attribute-slug
