Thanking you for your quick and valuable support.
I have confirmed my system with Service Provider. Each service provider has its own Bio page. I would like to make id dynamic. So we have to just change 'provider_id="6"' or worker="6" where "6" can be any.
At the template page we will get current page id, so is any way to determine for what user current page is assigned?
e.g. John is service provider and his bio page has id as "1122"
At the theme page i will get current page id with the help of function "get_the_ID()". I would like to know for which user this page assigned
Can you please help me?
