I have an WooCommerce installation that I’m using as a dealer inventory feed that syncs twice a day though an API feed using WebToffee’s Import/Export Pro. To prevent the media gallery from blowing up to a crazy size, I use this little snippet to delete the product and the products images when the product is no longer in the product csv import. Handy.
add_action( 'before_delete_post', 'delete_product_images', 10, 1 );
function delete_product_images( $post_id )
{
$product = wc_get_product( $post_id );
if ( !$product ) {
return;
}
$featured_image_id = $product->get_image_id();
$image_galleries_id = $product->get_gallery_image_ids();
if( !empty( $featured_image_id ) ) {
wp_delete_post( $featured_image_id );
}
if( !empty( $image_galleries_id ) ) {
foreach( $image_galleries_id as $single_image_id ) {
wp_delete_post( $single_image_id );
}
}
}
