here is an explanation of what we have:
multiple simple products for each t-shirt, we use an attribute set with color, size and sex.
The end product is a designed t-shirt, it has a pattern image and must take the t-shirts from the inventory (that's why we use a configurable product)
So, we have around 100 different simple products – but even more configurable products (each pattern gets it's own so the number is huge).
But what when we create a new simple product – let's say a blue t-shirt L sized which we didn't have prior to creating the configurable products. Is there a way to add the associated product to multiple configurable products at once – and not have to go into all products to add it?
Best Answer
So what you need is the way to add the simples to the configurable?
Then you can hook into saving of a product. Before save you check wether an ID is given, if not, add a flag. In after_save you check for the flag, if it is set, you load loop over all configurable products and add the new simple one.
