Dynamic pricing

[WStefanko]

Hello all, I am working on a jewelry manufacturing site. Since my prices are based on a daily gold market and weight of an item, is it possible to have Prestashop pricing reference an external site that would be updated daily? I know I could do a mass change but I would have to do that everyday by percentage. Right now I have all of my products on a very complicated excel file that I did not make.

 

Thank you,

Wes

@elpatron, I have figured out away to update my pricing directly to the DB at ps_product_shop in the "price" field. I had some help from my brother. My next question has to do with php/js. Would you know where to edit the "impact on price" files that would allow me to change my attribute by percentage(* or /) instead of (+ or -). I believe this is the last step before I import my products.

Thank you,

Wes

I looked at this, if you wanted to change all products by a flux rate (i.e. not have a flux rate by product/category).

 

you could do it this way:

 

create a file call FluxRate.php add the following code and file --> classes/FluxRate.php

<?php
 if ((!$specific_price OR $specific_price['price'] == 0) AND $id_currency != (int)(Configuration::get('PS_CURRENCY_DEFAULT')))
 {
  $fluxrate = 10;
  $price = $price * (1 + ($fluxrate / 100));
 }

 

$fluxrate above is set at 10%.

only does it for products, i.e. no attributes and only when in default currency

 

then find the following code (around line 1851 for 1.4) in classes/Product.php

 if (!$specific_price OR !($specific_price['price'] > 0 AND $specific_price['id_currency']))
  $price = Tools::convertPrice($price, $id_currency);

and add the folloing after these two lines

 if (!$specific_price OR !($specific_price['price'] > 0 AND $specific_price['id_currency']))
  $price = Tools::convertPrice($price, $id_currency);
 include('PriceFlux.php');

 

note: this is just a hack with very little testing...but basically it worked on my test machine.

 

of course then you would just change $fluxrate to fit suit your needs

If I have the products portion figured out for pricing, what about attributes by percentage? I saw a post in the past that they were working on it in 1.4. http://www.prestasho...ntage-increase/

Any thoughts on 1.5?

basically the code could be applied later in Product.php....i.e. before tax calculation but after attributes...

 

I have a module in development in this area...but not specifically for your requirement. Though (that I may in the future if there isn't another module that already does this...

 

have you researched one of the many mass update modules?

p.s. I looked at the link...what a mess...would take time to sort it out...

 

personally I like to do things simple...that just seems like a lot of work...

 

not knowing how you want to specifically fluctuate prices, the example I gave was for product base price...there are many ways to skin a cat.

Thanks for the help. My products cannot be adjusted by percentage once uploaded to the server(too much involved). My attributes change by percentage off of the price I upload. So in the products-combination generator you can put a value in the "impact on price:) field that either adds or subtracts to the base price. I am looking for where that is stored in the core. I would think you should just have to change the signs from +- to */ somewhere.

Thanks again

I have been looking at this (as opposed to doing my main work).

 

Can you be 'very' specific how you want this to work. I understand how to do it but I need to know how you want to manage the attribute values...
