My client needed to be able to have a different image on his main product page to that on his shop page.
This was actually not difficult to do. I created a new image field in Advanced Custom Fields as normal. I created it with a return value of image ID.
Create a new image field in ACF
Create a new directory in your theme
Within my theme directory I created the directories as follows:
wp-content/themes/mytheme/woocommerce/single-product
Copy the template file
Then I copied the file product-image.php from the WooCommerce plugin directory: wp-content/plugins/woocommerce/templates/single product
Edit the template file
All I had to do in the copied template file was edit one line of code!
Simply replace this line:
$post_thumbnail_id = $product->get_image_id();
With this line:
$post_thumbnail_id = get_field('single_product_custom_image');
Remember to change the name of the field (‘single_product_custom_image‘) to whatever your ACF image field is called.
That’s it, pretty easy in the end.
