Issue with “Any Text” Product Add-On

@axelseaa, Is that option created using Our plugin?

I have the “Product Add-Ons” from Woo setup, and am using your plugin to hide those options on all but a single variation on this product. When that variation is selected, it does show the add-ons correctly on the front end, however the text value entered is no longer saved and passed along to the cart / order process.

        
function woocommerce_add_cart_item_data( $cart_item_data, $product_id, $variation_id )
        {
            $add_ons = get_post_meta( $variation_id, '_variable_add_ons', true );
            if( $add_ons == 'no' ) $cart_item_data = '';
            return $cart_item_data;
        }

Based on my review of the plugin, when “add_ons” is true / yes, that essentially means that products add_ons should be disabled for that variation – correct? With that logic, I believe there is a bug and the above function should actually be:

        function woocommerce_add_cart_item_data( $cart_item_data, $product_id, $variation_id )
        {
            $add_ons = get_post_meta( $variation_id, '_variable_add_ons', true );
            if( $add_ons == 'yes' ) $cart_item_data = '';
            return $cart_item_data;
        }

This did correct the issue that I was seeing with my site. Hopefully this helps someone else as well!

Thanks, wee will look into that and see if we need to make any adjustments .
