Condition to check Product Type

In order to confirm, i have did

print_r($product);

and it shows product_type as null.
There is no value for product_type;
Here is complete array.

WC_Product Object
(
    [id] => 37
    [post] => WP_Post Object
        (
            [ID] => 37

Plz help..

Rather than call WC_Product directly, use the wc_get_product() function. Then try again.

Thanks mike, it worked but i am unable to understand that why WC_Product is not getting product type?

Because WC_Product has no type. It’s an abstract class.

The problem is likely that get_the_ID() isn’t returning the ID of a product.

$product_id = 10; // the ID of the product to check
$_product = wc_get_product( $product_id );
if( $_product->is_type( ‘simple’ ) ) {
// do stuff for simple products
} else {
// do stuff for everything else
}
