WooCommerce - Global $product is returning value null

My code is:

function sync_on_product_save($new_status, $old_status, $post) {
     global $post;
     global $product;

 if( 
        $old_status != 'publish' 
        && $new_status == 'publish' 
        && !empty($post->ID) 
        && in_array( $post->post_type, 
            array( 'product') 
            )
        ) {         

        print_R($product);
}
}

add_action('transition_post_status', 'sync_on_product_save', 10, 3);

• What do you need it for? The 3rd argument of your function contains the post data. – Jacob Peattie Commented Nov 26, 2018 at 10:23
• As Jacob mentioned, the $post object is passed via the action and through that you pretty much have access to what you need. However, to answer the question about the $product object specifically, you need to give it a product ID (which is the post ID) to have it contain anything where you're trying to access it. See my answer below which provides a solution using the product object. – butlerblog Commented Nov 26, 2018 at 13:33

The problem is that the $product object does not exist where you're trying to access it (when you're hitting "publish" in the editor).

As Jacob Peattie mentioned in the comments, you could probably get it all from the $post object. But, you can get the $product object from the $post->ID and then use the "get_" methods available in the object to get the values you need.

Here's your revised code for getting these values via $product:

function sync_on_product_save( $new_status, $old_status, $post ) {

    if ( 
        $old_status != 'publish' 
        && $new_status == 'publish' 
        && ! empty( $post->ID ) 
        && in_array( $post->post_type, array( 'product' ) )
    ) {         

        // Get the product object for this ID:
        $product = wc_get_product( $post->ID );

        // Use "get_" methods for values:
        $product_sku   = $product->get_sku();
        $product_name  = $product->get_name();
        $product_price = $product->get_price();
        $product_desc  = $product->get_description();

        // Do what you need for 3rd party here...
    }
}

add_action( 'transition_post_status', 'sync_on_product_save', 10, 3 );
