Quantity upgrade with 0.2 instead of 1

[Webbart]

Hi,

 

I already searched but couldn't find how I can increase or decrease the quantity in the shopcard with 0.2 instead of 1

Is there any possibility?

I use prestashop 1.6

 

Thanks a lot

Prestashop can deal only with whole numbers. There are a lot of commercial modules available that can deal with fractions.

I'm sure it can be done with the code somehow.

But I don't know how and where exactly

If you are sure it can be done - your are correct.

If you don't know where - let it be as it is. You had to change approximately 10 to 15 files to achieve that.

I would never do that work if a modules is available which does it good.

I've no problem to make changes to files and database tables

I'm a programmer

But I have to know what and where

Can somebody help me please

[Scully]

If you are a programmer - do a recursive full text search on all PHP and TPL files with the search term "quantity". But I am willing to assist with a little help.

 

Database tables to change (might be more than i found in quick search)

 

- ps_discount
- ps_orders
- ps_order_detail
- ps_order_return_detail
- ps_order_slip_detail
- ps_pack
- ps_product
- ps_product_shop
- ps_product_attribute
- ps_product_sale
- ps_specific_price
- ps_stock_mvt

 

Core Files:

- prestashop/classes/Attribute.php
- prestashop/classes/Cart.php
- prestashop/classes/Customization.php
- prestashop/classes/Discount.php
- prestashop/classes/Order.php
- prestashop/classes/OrderDetail.php
- prestashop/classes/OrderHistory.php
- prestashop/classes/OrderReturn.php
- prestashop/classes/Product.php
- prestashop/classes/ProductSale.php
- prestashop/classes/QuantityDiscount.php
- prestashop/classes/StockMvt.php
- prestashop/controllers/CartController.php
- prestashop/controllers/OrderController.php
- prestashop/order.php
- prestashop/cart.php

 

TPL Files

product.tpl

product-list.tpl eventually

 

And don't forget to tell us how much time it needed to change all.

You might spend some time searching the forum. I remember vaguely that someone was busy with this some time ago but I am not sure how far he came.

it might be possible it it would be very difficult (and it will change alot in Prestashop core files + database) to have quantity like 0.2

My recommendation is to keep the quantity as it is (an int value) but try to change the unit that you are using to measure your product quantity (eg: instead of 0.2m, say it 20cm)
