Question

PHP

Hello!
Help the old man please.
How to make a share/repost/retweet button.
In the social I don’t know much about networks, it’s clear that you need to take and copy-paste the code.
But I also need the link/path of the article to be present in the code, which I will insert with the Joomla code.
On VKontakte it worked, on the rest it doesn’t work.

Answer 1

<div class="ya-share2" data-services="collections,vkontakte,facebook,twitter" data-url="http://site.ru/news/$1" data-counter=""></div></div>

I did everything with one code
