Payment fees and discounts are not shown correctly

This modification fixes bug when you see different Totals generated from ro_basket.php (read - only basket used at many places of VirtueMart, checkout.index, checkout.confirm). In user order total the payment fees and discounts are calculated by percent of order Total including VAT. If you want both to show correct percentual discount or fee (without VAT) you have to modify your ro_basket.php in /administrator/components/com_virtuemart/html/ro_basket.php

We fixed it this way:
Search for $payment_discount = $ps_checkout->get_payment_discount(.... in your ro_basket.php in html folder and remove second parameter $total so it says only:


$payment_discount = $ps_checkout->get_payment_discount($payment_method_id);

The problem is that $total is incl. VAT and it should not be. There should be subtotal there.

How to preselect VAT in product form in VirtueMart

We are very glad to run our own servers, so we can use Midnight Commander in Putty over SSH console and search all the files in matter of couple seconds. How do we debug VirtueMart? We have FireBug installed in Mozzila and if any form doesn't seem to show what we would like, we search all VirtueMart for css class of the element. And than search for appropriate functions and classes.

To the point of this article:

Modify your ps_tax.php in /administrator/components/com_virtuemart/classes/ps_tax.php, search for function list_tax_value( ... and right after $db = new ps_DB( ); around line 235 and insert following line if your tax ID is 3.

 

if (!isset($selected_value_id)) $selected_value_id = 3;

 

How to get your Tax Id? It is shown in product form when adding products in VAT listbox as "3 (19 %)" where 3 is the ID.

 

This will show your default VAT for every form which gives you the option. We know, this is not a nice hack but works.

Speeding up Virtuemart

One of the common problems with VirtueMart is it's speed. Here we provide advices how you can make your site with 5 thousand products and more to load from 50 to 500 milliseconds (from localhost) depending on actual hardware configration of your server.

 

Firstly it will work only if you don't have any legacy mode plugins in your Joomla installation. The problem with legacy mode plugins is that they don't support caching top speed caching. Therefore,  if you see that all of your plugins are compatible you can disable Lagacy mode in Joomla. How to find out if everything is compatible? Go to Extensions - Install/Uninstall - Components and you will see column Compatiblity. If all your components are checked, than everything is all right.
