Limit Virtual product quantity to one.

[seb776]

Heey,

 

That's a nonsense to have multiple quantities of a virtual product (in most cases).

 

Is there a trick/configuration to do this ? a small module ?

You mean you only want people to download the product once? Or just don't use quantities for it?
If the latter, I'd honestly set an insane number like 9999999999 or simply disable stock management if you're only selling virtual products

[seb776]

oops, sorry I missed your answer.

 

 

 

Or just don't use quantities for it?

That's it.

 

It's not related to stocks quantities, Stock management is disable. It's related to the fact that a customer may add twice the same virtual product in it's cart. So he will it twice for the same product.

 

But now I've just made a small free module ( http://prestashop.seb7.fr/shop/en/modules/2-limit-virtual-products-quantity.html )

oh, good job!

Can you provide me access to code of your module? I'm in this situation at this time.

I override the front controller CartController and listen the function processChangeProductInCart, but if i can see you code i will save many time.

 

I'm not lazy man. My time is very, very short.

 

 

THANKS!!

Forget it.

 

If you want to listen on add or update cart, use the hook actionCartSave and then 

 

$this->context->controller->errors[] = Tools::displayError('Max quantity is 1 for this product.', !Tools::getValue('ajax'));

 

for show errors to the front.

 

Is better than override, if you need to distribute your module.

One simple contribution.

 

There are one hook that is not listed on documentation and is exactly what i need at this moment.

 

It is actionBeforeCartUpdateQty that is called (as the name says) BEFORE  add or update product in cart. Oppose the actionCartSave that is called AFTER.
