How do I check if the user is a site owner in a network?

Question

I was accidentally using is_admin() to check if a user was an admin and found out that function is not checking that. So I looked for another one and I found is_super_admin() but that checks if you are a admin of a network of sites or owner of a single WordPress install. I have a network site and I want to know if the user is the owner of the blog. I do not want to use roles. I want to check if the user is the owner of the blog.

Answer 1

I have had similar issues with this in the past, WordPress really does need a is_user_admin() function.

In the meantime I think the best way to do this is to test if the user has certain capabilities.

function is_user_admin(){
    if(!is_super_admin() && current_user_can('activate_plugins'){
        // User is an admin
    }
}

Reference:

• Administrator roles
• current_user_can()

Answer 2

The 'activate_plugins' roll only works if superadmin has enabled that privilege in network settings, which they often don't -- it's disabled by default. The proper way is to use the 'administrator' role.

if(current_user_can('administrator')) {echo "User is admin!";}
