Whenever a user is selecting a different product attribute I am generating a new photo and setting it for variation. The problem I have is that I do not know how to show a newly generated photo? If I reload the page and select the same attributes I get the needed image, but I want this to happen instantly after the user selects the attributes (and after the photo is generated).
Here are the scarps of the code I am using. Uploading an external link
$upload = wp_upload_bits( basename( $mockImageUrl), null, $response['body'] );
Generating an attachment and returning a new url:
$attachment_id = wp_insert_attachment( $attachment, $upload["file"] );
require_once(ABSPATH . 'wp-admin/includes/image.php');
$attachment_data = wp_generate_attachment_metadata( $attachment_id, $upload["file"]); // we can think about removing this later
wp_update_attachment_metadata( $attachment_id, $attachment_data );
set_post_thumbnail( $variation_id, $attachment_id );
echo json_encode($mockImageUrl);
Now new photo for variation is set, but the user still sees an old photo until refresh.
