WooCommerce: Redirect URL With SKU To Single Product Page

Let’s say your WooCommerce product has the following permalink: example.com/shop/t-shirts-tops-and-blouses/t-shirt-casual-v-neck-longsleeve-green-medium-cotton-stretch

Wouldn’t it be shorter, more fun and neater if you could also reach the same exact single product page by using example.com/sku00001 in the browser bar, where “sku00001” is the product SKU?

Well, in today’s snippet we will create a simple redirect from a custom URL that contains the product SKU to the product page, so that you can use the URL “shortener“ in your email marketing, display advertising, blog posts and anywhere you want to show a “pretty link” instead of a full, long, boring product page URL.

Enjoy!

add_action( 'template_redirect', 'bbloomer_redirect_sku_in_url_to_product' );

function bbloomer_redirect_sku_in_url_to_product() {
	if ( is_404() && ( $sku = $GLOBALS['wp']->request ) && ( $id = wc_get_product_id_by_sku( $sku ) ) ) {
		wp_redirect( get_permalink( $id ) );
		exit;
	}
}

• The first line hooks the function bbloomer_redirect_sku_in_url_to_product to the template_redirect action. This means the function will be called whenever a WordPress template is redirected, which is typically on every page load.
• The bbloomer_redirect_sku_in_url_to_product function itself is commented to explain its purpose, which is to redirect URLs containing a Stock Keeping Unit (SKU) to the corresponding product page.
• Inside the function, we first check if the current page is a 404 error page using the is_404() function. This is because we only want to redirect URLs that result in a 404 error, which might be the case if someone types in a product SKU directly in the browser address bar.
• If it is a 404 page, we then try to retrieve the request string from the global $wp object.
• We then use the WooCommerce function wc_get_product_id_by_sku($sku) to try to get the product ID for the SKU in the request string.
• If a product ID is found for the SKU, we use the WordPress function wp_redirect(get_permalink($id)) to redirect the user to the product’s permalink. The get_permalink($id) function retrieves the permanent URL for the product with the given ID.
• Finally, we use the exit function to stop the function from executing any further code after the redirect.
