Behavior

Actually, I can’t even make it work (latest Woocommerce).
The yoursite.com/your-single-product/?colore=blu (where colore is the attribute and blu a variation of the product) method doesn’t do anything. I just see the default product page.

As the official support suggested me, adding “pa_” in front of the attribute (from “colore” to “pa_colore” worked.

Thanks for the hint.
Where exactly should the “pa_” be?
It’s not really clear to me.

Before the attribute (ie. color, size, whatever you name it)

tried this but it didn’t work. just to be sure i did it right the “pa_” should go before the attribute name? ie. if my attribute is named “Color” than i should name it “Pa_Color”?

Exactly.
In this example, the attribute is “colore”.

Thanks for using the plugin.

The most recent update 1.0.2 optionally removes the need to use ‘pa_’ in front of your attribute title. Now you can use pa_color=xxx or color=xxx.

Hope you enjoy!
