WordPress multi-site, how to select other sites that are not the main one

Question

I'm working in WordPress... and I need to show different post on the footer. The thing is... I had a multi-site with two sites, so It was easy to customize as I want each footer with

if(is_main_site()) {

} else {

}

But now I have added another site, how can I select, with php one site or other?

I have checked WordPress codex, but I can only find is_main_site referring to multi-site.... does anyone has an idea about what can I use?

Thank you

You should use a conditional function.

WordPress provides the get_current_blog_id() function, using this function you can create a switch statement to add your custom footer.

Also, you can check the get_blog_details function to retrieve the current site details.
