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!

	global $product;
	if ( ! $product->add_to_cart_url() ) return;
	echo '<p><a href="' . $product->add_to_cart_url() . '" class="single_add_to_cart_button button alt" target="_blank">' . $product->single_add_to_cart_text() . '</a></p>';

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.

  1. 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 );
  2. 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
