woocommerce add_to_cart function not add two different products in cart

Question

i am creating a custom button to add products to cart using add_to_cart($product_id, $quantity) function. It's working well for the single property but when I change product_id with another product id then it shows error.

$cart = $woocommerce->cart->add_to_cart($product_id, $quantity);

when I try same with different product_ids it stops working. any solution?

What is the value of new $product_id that you change to? Does it really exist? — user4055330

Okay, thanks for the help. Finally, the problem is solved. Actually, 93 product_id product is out of stock that's why it returns false. add_to_cart() function does not work with a product out of stock.

If you enable stock management at product level (option in inventory tab) and you "allow backorders" (option), add_to_cart() function will work…
