I have to admit that I am a fan of what Amazon does, and there’s a feature I really like.
You know when you’re looking for a product, you find it, you’re about to buy it and at this moment moment, on the product page, you see a little notice stating that a newer version of the product is available! Wait! What? I was about to buy an already old version of a product I don’t even own yet? ;-)
Here is the result:
Ok, so, to implement this feature within WooCommerce, it’s fairly simple. I wrote the snippet below so that you guys can start selling more than one version of a plugin (an old one and a new one!). Simply paste the code in functions.php in the theme folder and you’re done!
Please note: this code has been tested with WordPress 4.5 and WooCommerce 2.6 Beta 1.
