To by only one item of a product by year - how to do this?

[LuisMP]

Hello

I work in a company that wants the following caracteristics on their webshop:
Suppose that there are 10 itens to sell. Each costumer in each year can only by 1 item of each product.
He can by, for an year, item1,item2,item3...item10, but he cannot by, for exemple, item2 two times in the same year.

When the year ends, everything resets and starts over.

This is because this group of costumers has very special prices, so the restrition.

Can you help please?

Best Regards

Strange requirement. Yet acceptable.

I like it.

May be try with customer group with catalogue rules.

Can´t figure out how to do this. Already tried with groups and rules, can´t make it happen.

 

This is really important for us...any help is welcome:)

 

Thanks

prestashop doesn't allow restriction on product selling on its quantity.

need to fully customize feature.

Although you can achieve by overriding cart controller and add conditions in add and update methods of Cart class.

Quick 

  - Override Cart class

  - Add and update method of Cart.php, put own logic in to check whether customer is eligible or not ?

  - If eligible then grant customer to add item to cart otherwise throw error or something .

i've got maximum product quantity module that works similar to this,

i think that development of option to allow product only one time per year will be very easy

Ok I tried this:

 

Created a column in DB in ps_customer called "article_a"

In this field I put "1" if customer can by the article, "0" if not.

 

Now the bad parte is the code...

 

I´m thinking of something like...

get product reference (lets make this reference also "article_a")

check if column named "article_a" has a 0 or 1 in customer DB

If it has a 0 give error.

 

I really don´t know how to program is php code, so go get a wishy befores reading the code below. Drink afterwards in a row:)

 

 

$a=$this->reference  (get the product reference)

If ($this->->context->product->$a==0) (get value from column with the same name as reference, if it equals 0...)

{$this->errors[] = Tools::displayError('Resuktou!!', !Tools::getValue('ajax'));

}

 

I know, it´s dreadfull...

 

My questions are:

how to get the value of reference of product?

how to get value of new column in customer DB ith the same name as reference?

 

Sorry, I have some notions of old code but this is all to me...

 

Best regards!

oh by the way vekia, if you are thinking to implemente this here are some suggestions:

Ability the quantity each client can by per item. It could be one or two or whatever.

Ability to edit that quantity. For exemple now I want to let the cliente get one more item, I go there and change 0 to 1.

 

Best regards
