WooCommerce: Edit External Product Image URL

We’ve already seen how to open the External Product “Buy Product” button in a new browser tab – and now it’s time to complete the full picture for External/Affiliate WooCommerce Products: how do we also link the “featured” image to the same external URL?

Our goal is to get the External Product featured image to link to the same “Buy Product” URL

PHP Snippet Part 1: Disable Zoom/Gallery (For External Products)

If we want to link to a URL, we first need to disable the default WooCommerce zoom and lightbox gallery functionalities.

You can use https://businessbloomer.com/woocommerce-disable-zoom-gallery-slider-lightbox-single-product/ for that.

Also, make sure to disable the Product Gallery e.g. that the external product has only 1 featured image.

add_filter( 'woocommerce_single_product_image_thumbnail_html', 'bbloomer_image_link_external_url', 100, 2 );

function bbloomer_image_link_external_url( $html, $post_thumbnail_id ) {
   global $product;
   if ( ! $product->is_type( 'external' ) ) return $html;
   $url = $product->add_to_cart_url();
   $pattern = "/(?<=href=(\"|'))[^\"']+(?=(\"|'))/";
   $html = preg_replace( $pattern, $url, $html );  
   return $html;

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme 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 free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked 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 on PHP 7+.
