Hello! Like in Beta Theme on the announcement page, display “Category” as a link. Like in Violet Theme
Violet

Beta

Probably you would go with code:
<a href="<?php echo osc_item_category_url(); ?>"><?php echo osc_item_category()['s_name']; ?></a>
if osc_item_category does not return anything, try osc_item_category_name
if osc_item_category_url does not exists, try osc_search_url('page' => 'search', 'category' => osc_item_category_id())

The page does not load with this code. White background. In the original view on the code, the page ends.
In Violet theme, your code works. No Beta

Read whole message. Check your error log.

[04-Feb-2020 18:15:56 Europe/Moscow] PHP Fatal error:  Call to undefined function osc_item_category_url() in /home/p/www/public_html/oc-content/themes/beta/item.php on line 13

Category without a link is added there

So you see function does not exists, you have alternatives in my post, you must be more proactive when doing customization in your site and test all possibilities.

I tried everything, even this
<a href="<?php echo bet_item_category_url(osc_item_category_id()) ; ?>"></a>

Does not work

@Olime
osc_search_url(array('page' => 'search', 'category' => osc_item_category_id()))


Thank you so much for the quick help. Everything works fine, even the city finds it through this code. Why there used to be an error, that I wrote the code wrong.
 Thank you
