I am creating a woocommerce theme and I have product variations i.e. size which is displayed on product details page but problem is that I want to get all variations in my custom php page by using product id, can any one help me.
Thanks in advance.
You can use: $available_variations = $product->get_available_variations();
If this is a single style template, make sure you add global $product;
near the top.
From there, you can foreach through the variations and do as you wish... since you didn't have any specific output I hope that this sets you on the right track.
