function wpuf_update_product_sku( $post_id ) {
if ( isset( $_POST['_sku'] ) ) {
$user_id = get_current_user_id();
update_post_meta( $post_id, '_sku', $user_id );
}
}
add_action( 'wpuf_edit_post_after_update', 'wpuf_update_product_sku' );
add_action( 'wpuf_add_post_after_insert', 'wpuf_update_product_sku' );
if ( isset( $_POST['_sku'] ) ) {
$user_id = get_current_user_id();
update_post_meta( $post_id, '_sku', $user_id );
}
}
add_action( 'wpuf_edit_post_after_update', 'wpuf_update_product_sku' );
add_action( 'wpuf_add_post_after_insert', 'wpuf_update_product_sku' );
All done, submit a product using frontend product form & check the product SKU in wp-admin. The SKU id will be the user id.
