Hide "contact seller" and "sold by" button for unregistered users

-- url of the page with the problem -- : www.abierto.uy
-- HikaShop version -- : 4.3.0
-- HikaMarket version -- : 3.1.0
-- Joomla version -- : 3.9.18
-- PHP version -- : 7.3

Hello

Given the characteristics of the site business I'm working on, site visitors need to be unable to see the vendor´s data, or contact the vendors unless they register as users.
In the hikamarket configuration I can hide or show the "sold by" section, but I would hide it for everyone, visitors and users, similar happens with the hikashop configuration, "Show the contact button on the product page" can be hidden , but for everyone, visitors and users.

Is there a way that only registered users can see the "sold by" section and the "contact button"?

Thank you very much, greetings!

Hello, thanks for answering

When it comes to programming, I am quite a novice, but I will try to follow your instructions.
What is the function that I should deactivate, is it a plugin that I find in the extensions manager?

I understand that by canceling that function, I should add the code in view for the HikaShop product page, with which to check if there is a session started on the site, to show or hide a link to the seller page, correct?
In this regard, two questions:
1- in object this->element->vendor do I find the url of the vendor page?
2- I was reviewing joomla documentation and it seems that the user object connected at the moment, I get it as follows

use Joomla\CMS\Factory;
$ user = Factory::getUser();

I understand that if $user is null, it is because there is no user connected, is that so?

I really appreciate your help, regards!

Good Morning

I fully understand and am very happy with the help they have given me.
With this information, I think I can solve my need

Thank you very much for your great help.

Hello, I hope you are very well

I am modifying the view of the product page, following your instructions and everything works as you mentioned.

But I have a problem, in the post you recommended to me, www.hikashop.com/forum/20-market-feature...username.html#175004

in the code to generate the url of the vendor that is published there, in the first line it must be saved in a variable, the user id joomla of the vendor

$joomla_user_id = 0; /* This variable must contain the joomla user id */

Hello

It is true, do not check the messages back and keep the latest.

It worked perfectly, thank you very much, you are very kind.

Cheers!

Hello

I ask you something else about it.
Can you tell me the view corresponding to the items (products) listed? Attached screenshot, to include the same access control to the seller page.

Thanks greetings!
