Custom link on product page (with variants)

-- HikaShop version -- : 4.4.3
-- Joomla version -- : 3.9.5
-- PHP version -- : 7.4.14

Hi, I need to make custom link (to demo site) for product and it's variants. What it the better solution: use some standard field or maybe custom field?

I've try do use "product_code" but it shows code in a strange way - while open product page it takes code form php but while switching on variants it takes code from java script (at least that's how I understood the action).

I want to past code to view like it:
<div class="button_cont" align="center">
<a class="butdemo" href=" mywebiste.com/ <?php echo $this->element->product_code; ?>" target="_blank" rel="nofollow"><span>See demo on-line</span></a>
</div>

Thank you in advance
Greg

Thank you for your replay, problem is that your code is not dynamic - it doesn't change while choosing variants (at least on my website).

When I use this code:
<span id="hikashop_product_code_main">
<?php echo $this->element->product_code;?>
</span>
it works perfectly but don't know how make a link from it. - after switching to variant link is breaking. Also notice that without id="hikashop_product_code_main" it's also not dynamic so it works like your code.

Please look on my site: opop.pl/product/43-cosmetica and try to choose color variant, your code doesn't switch.
I'v put there all 3 codes that we are talking about so can touch the problem.

Ps.: I'm new to HikaShop and made many changes in configuration and few in views... is it possible that I'm the reason ?

Hi Nicolas, did you look at my webiste? Please notice that your code is now odded outside of a div with an id finishing by _main and it's not changeing while choosing variants. To explain how it's done on example page here is the code:

<p> Hika Support 1st:
<?php
if(!empty($this->element->main))
echo $this->element->main->product_code;
else
echo $this->element->product_code;
?>
</p>

<p> Hika Support 2nd:
<?php
echo $this->element->product_code;
?>
</p>

<p>Good one, with id="hikashop_product_code_main"
<span id="hikashop_product_code_main">
<?php echo $this->element->product_code;?>
</span>
</p>

Whole problem is that I don't want to use div with an id finishing by _main but only then product code is changing as I want. Hope it's clear now

Regards
Greg

Could you write some example of code in show.php file, please? I don't understand where to put it and how.

As I wrote on my first post maybe it's better to use custom field in my task - what you think about it?

Hi, Nicolas, thak you very much. Code solved the problem.
