Customisation not applied when changing Varient

-- HikaShop version -- : 3.2.0
-- Joomla version -- : 3.8.2
-- PHP version -- : 7.1.11
-- Browser(s) name and version -- : all

I have customised the display so some categories don't display the VAT amount, this works correctly when the product is displayed. When the variant is changed however it ignores the customised display.

Is there another file I need to override in order to achieve this? or is it possible in a future release the ability to display prices including VAT or excluding VAT can be set at the category level?

Dave

Hi Nicolas,

I have double checked this evening the process that I used which is:
I copied the product / show_ to create a new file product / show_inc_vat.php
I then edited the link to the prices to product / listing_inc_vat.php from product / listing_price.php
I have made all my edits to the product / listing_inc_vat.php file

I have attached my listing_inc_vat.php file and for reference price with tax = 2 in options

I just copied my edit and pasted it over the default product / listing when this is in place it works as expected, however, I need to display some products with VAT and others without VAT and all of them have variants.
This says to me that the variants aren't following the custom file but reverting to the standard version. How do I stop this behavior? I would expect the variants to follow the display file that's selected in the product options.

Hi,

So editing the 'show.php' file has a global effect which can't be overridden for certain views?

The requirement I have is some products are business to business which the clients don't want VAT showing, other products are to the general public which expect to see the VAT amount. Up till this point the overrides appeared simple and intuitive.

from show.php is the following is it possible to change the if statements to take the required listing_ file dependant on what is set on the Product - Display - Page Layout section?

201	<div id="hikashop_product_price_<?php echo $variant_name; ?>" style="display:none;"><?php
202		if((int)$this->params->get('show_price', -1) == -1) {
203			$this->params->set('show_price', (int)$this->config->get('show_price'));
204		}
205		if ($this->params->get('show_price')) {
206			$this->setLayout('listing_inc_vat');
207			echo $this->loadTemplate();
208		}
209	?></div>

Hi Nicolas,

Thanks for your help so far, having read the code I thought the below would have worked, can you correct the error in my logic please

	<div id="hikashop_product_price_<?php echo $variant_name; ?>" style="display:none;"><?php
		if((int)$this->params->get('show_price', -1) == -1) {
			$this->params->set('show_price', (int)$this->config->get('show_price'));
		}
        if ($this->params->get('show_price')) {
            if ($this->element->main->product_layout('show_inc_vat')){
              $this->setLayout('listing_inc_vat');
                echo $this->loadTemplate();
        }
            if ($this->element->main->product_layout('show_exc_vat')){
              $this->setLayout('listing_exc_vat');
                echo $this->loadTemplate();
        }
            else
              $this->setLayout('listing_price');
                echo $this->loadTemplate();
        }
	?></div>
