Using the product attribute values into the formula?

Wasn’t possible (as [product_meta] shortcode automatically converted the value to number), however, I have just added new convert_to_numeric shortcode attribute to [product_meta] in our development version, so now you should use:

[if_value value="{product_meta key='attribute_pa_media-type' convert_to_numeric='no'}" compare_operator="equal" compare_to_value="paper"]x*4.9[/if_value]

Yes, it will work with variable products (i.e. will set different prices for each variation depending on variation’s attributes). Small fix in formula is needed though:

[if_value value="{product_meta key='attribute_pa_media-type' convert_to_numeric='no'}" compare_operator="equal" compare_to_value="paper"]
	(x+0.2)*[product_meta key="attribute_pa_number-of-prints"]
[/if_value]
[if_value value="{product_meta key='attribute_pa_media-type' convert_to_numeric='no'}" compare_operator="equal" compare_to_value="cardboard"]
	(x+0.5)*[product_meta key="attribute_pa_number-of-prints"]
[/if_value]

I.e. { and } brackets are only used inside shortcodes attributes, and inside shortcode’s content you need to use normal (i.e. square) brackets ([ and ]) for shortcodes.

If anyone else has similar tasks – we’ve just released new plugin v2.2.1, where we have:

1. added [product_attr] shortcode, which would be the correct way of retrieving the product’s attributes, e.g.:

[product_attr attribute="number-of-prints"]

You can also get product attribute’s value as suggested earlier by:

[product_meta key="attribute_pa_number-of-prints"]

However it seems that this way only works for variations, but not for simple type product’s attributes, while [product_attr] shortcode works for all types of products.

2. added convert_to_numeric attribute to the [product_meta] shortcode (attribute defaults to yes).
