Set upload rules to product variations
What if you have a variable product and you want to set different upload rules for every variation?
This is easily doable by activating only a subset of the upload rules for every variation, in this way your customers will be asked to upload a number of files that depends by the variation chosen.
First of all, let’s create all the upload rules that are needed by the single product variation, for example for a ‘notebook’ product we add three upload rules, a ‘Full page’ picture a ‘Centered’ picture and a ‘watermark’ picture:

For every variation we can choose which upload rules could be used, for example we have a variation for the ‘notebook’ product that let the customer to customize the product with a watermark printing and a centered logo, the we will choose a subset of rules to be used, in our example :

Try adding this product with ‘Centered picture’ and ‘Watermark’ to the cart in order to see that these specific file will be asked for this product.
