Calculate Price per Unit automatically from Price and Quantity (Product Feature)

[each1teach1]

Hi Everyone!

 

we  sell bottles of different size.

the bottle size is the product feature with the id# 9.

It is formattet like: "0,7" (in liters)

 

divisions ain't rocket-science

 

I want the price per unit to be calculated automatically when the price is set.

 

like:

read price

read feature id=9 (liters -- replace comma by point?)

divide and save as price per unit.

 

i would highly appreciate any hints!

 

Thank You!

 

(ps 1.6.1.4)

I'm not sure what exactly you need. I wrote module showing price per own define units:

 

 

But i think this is not what you looking for?

[shokinro]

you can set Unit Price of each product at back office - Catalogue - Products - editing product, Prices tab

 

You will see Unit Price field and per field.

So you can enter $1.5 per liter

 

If there is discount, prestaShop will automatically calculated discounted unit price.

Thanks a lot for your quick help.

 

entering the price per unit works fine. it is also displayed correctly.

 

when I change the price of a product, the size e.g. 1 Liter stays the same.

I was wondering if it was possible that the calculation of the price per unit could be automatic.

 

as I am new to prestashop and the programming I dont know how to access the feature id=9 of a product (my bottle size in liters)

also I dont know the command, to write the unit price.

Neither do I know where to place it.

 

or am I missing some vital point?

 

thank you!

when you change product price, should also change price per unit at product management page. I think this is the normal way to handle it.

unless the core does not provide the function then you can consider to modify or customize it, because custom changes will be lost when you upgrade your store.

 

anyway, if you really want to customize it, you will need to learn the Smarty and PrestaShop programming.

 

the data is loaded in product classes in controller class /controllers/front/ProductController.php and passed the data to view(theme file) via Smarty.

and the theme file is in /themes/yourthemefolder/product.tpl

ok thank you 

 

I hope I will manage to find the command myself

 

if so, I will gladly share it, but this could take quite a while.

 Hello everyone I currently have the same problem,

which can be found on the product overview page in the miniatures: Folder tree: /PRS01/templates/catalog/_partials/miniatures/product.tpl
(purchased template)
also the base prices are not shown the product.tpl times appended because strangely enough the {hook} in line 107 is written.

 

But it is not shown and calculated in the frontend.

 

Here the link to the current test page:

www.pritumble-test.de

 

Attention, when you click on the logo or home you will get back to the actual store, I still have to fix the error, so you can screw in the testshop in peace.
