How to add applied VAT and link for shipping costs to product page

Hi,

Regarding the display of the price on the product page, you can change it thanks to the option "show taxed prices" setting of the HikaShop configuraiton to either have the price with or without taxes or both.
You can also use translation overrides if you want to add the tax rate after the price display:

Regarding the shipping costs, If you activate the "shipping price per product" of your shipping methods and set prices per product when you edit them, you can have these shipping costs directly display on the product page thanks to a setting inthe price per product plugin that you can find when you edit it via the Joomla plugins manager.
Otherwise, if you want something more static, there are several solutions based on what you really want.
It could be a custom field of the table "product" where you could select some text in each product configuration page to be displayed on the product page.
Or a fixed text you would add to all the product pages either with a custom HTML module, or a modification in the view file "show_default" via the menu Display>Views.

Hi,

In $this->element->prices you have an array of price objects (because a product can have several prices).
Then, in each price object you have attributes like price_value, price_value_with_tax and a taxes attribute which is an array of tax rates (because a price can have several tax rates applied to it. Each tax rate object has several attributes like tax_rate, tax_namekey or tax_amount.

Hi,

Where in my message did I said that ?
I said the exact opposite.
As I said, you can access the tax_rate attribute in the tax objects of the taxes array of the price object in the $this->element->prices variable. So there is nothing to calculate. Just use the variable like I explained.

Hi,

Your code is wrong.
You're using the key '0' to access the first element of the arrays, but it's not always the case.
For the prices array, the key correspond to the minimum quantity of the price. So you usually have 0 (so that you can purchase a quantity of 1, 2, etc) and thus it should work.
However, for the taxes array, the key is not 0.
Hence, your code should be:

<br /> (inkl. <?php
$firstTax = reset($this->row->prices[0]->taxes);
 echo $firstTax->tax_rate*100.0; ?>% MwSt) </span>
