WooCommerce: Open External Product Link In New Tab

Today I start a personal WooCommerce customization marathon as I try to relaunch my personal project A Piece of Sicily (a Sicilian products marketplace, WPML friendly, with products uploaded by vendors and external (affiliate) products).

Each week I will share a snippet I’ve personally coded, so that you can follow me along the going-live path and actually see the results on the live site.

This time, we’ll talk about External Products, and specifically at how to Open the external add to cart URL in a new tab, so that users stay on your WooCommerce website even after visiting the affiliate link. Enjoy!

You can test the “link opening in a new tab for WooCommerce external products” functionality at https://www.apieceofsicily.com/en/shop/sicilian-wine/orestiadi-il-bianco-di-ludovico-riserva-2017/

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101

  1. Thank you very much!! Why did the button turn purple? My newspaper theme’s CSS works on all product pages except the woocommerce button

    1. Try removing the “alt” class from the button

  2. Thank you very much !! I’ve been looking for something like this for a long time in the form of a plugin or something else. Works great!
    I have a question, could you help with Sticky Footer external affiliate link? for add to cart it works ok but for external tools it is impossible for me.
    I think this problem also comes back to the YITH Wishlist (probably to others as well) for affiliate/external link products the link cannot be configured and for normal products they can be added to the basket directly from the wishlist.
    Thank you in advance.

    1. Hello Rafael, thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

  3. The above snippet works perfectly in WooCommerce Single Product Page!!

    But how about in WooCommerce shop/category Page?

    1. Hi Ana thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

      1. Hi, you can try this code, it works for me on Kadence theme

        function ns_open_in_new_tab($args, $product) 
            if( $product->is_type('external') ) {
                // Inject target="_blank" into the attributes array
                $args['attributes']['target'] = '_blank';
            return $args;
        add_filter( 'woocommerce_loop_add_to_cart_args', 'ns_open_in_new_tab', 10, 2 );
  4. Cannot redeclare function woocommerce_external_add_to_cart.

    What am I missing?

    1. Hi Shane, where did you add this code?

      1. As a snippet

        1. Gotcha! Instead, try adding that to your child theme’s functions.php. Redeclaring a function won’t work with Code Snippets or similar plugins

          1. Is there a way so we’re able to add this to snippets.
            Functions.php works until a theme is updated. Thats why snippets are so nice to work with.

            1. Nope, can’t overwrite pluggable functions via Code Snippets

              1. how about a specific product to open in a new tab?
