如果图库存在，则从 WooCommerce 图库中删除特色图片

Question

I'm trying to remove the featured image from woocommerce gallery, but only if gallery exist.

I have tried " Remove featured image from the WooCommerce gallery " answer code to remove the image, but also removes from other products too that don't have gallery, leaving the product without the main image.

I know that Wordpress has a function get_post_gallery() to check this, but what about woocommerce?

So, my main question is: How to check if a product gallery exist to implement this code?

Answer 1

Just add follows code snippet -

function woocommerce_single_product_image_thumbnail_html( $html, $attachment_id ) {
    global $product;
    $attachment_ids = $product->get_gallery_image_ids();

    return ( $attachment_ids && $product->get_image_id() == $attachment_id ) ? '' : $html;
}
add_filter( 'woocommerce_single_product_image_thumbnail_html', 'woocommerce_single_product_image_thumbnail_html', 99, 2 );
