Why can't get product id in woocommerce?

Question

WooCommerce

Hello.
Can you please tell me why I can't get product id in wordpress(woocommerce)?
I'm using the "contact form 7" plugin and before submitting it, I want to get the product id so that I can send it to the database later.
To do this, there is an action "wpcf7_before_send_mail":

add_action('wpcf7_before_send_mail', 'mysite_before_send_mail');
function mysite_before_send_mail($contact_form) {
global $product;
var_dump($product->get_id()); // Пишет что тут ошибка Uncaught Error: Call to a member function get_id()
}

But if I use the standard wordpress action like wp_footer, then everything works.

add_action('wp_footer', 'mysite_custom_order_form');
function mysite_custom_order_form() {
    global $product;
var_dump($product->get_id());
}

I understand that it's all about the "wpcf7_before_send_mail" action. Is it possible to send an id to it somehow?
Thank you.

Hello.
Contact Form 7 sends form data via AJAX, so there are probably no global variables.
I have not encountered such a task, but I think you can either try to create your own shortcode for CF7 and pass the product ID through it, or use the Contact Form 7 Dynamic Text Extension plugin , it also seems to do something similar.

try dumping just the contents of var_dump($product) and see what you have in the $product variable. Maybe then the reason will become clear.
