   Sorry if this issue has already been addressed and answered, but I can't find it anywhere.

   How do I/Can I fetch the current site's ID?
   (Or blogs? sorry, not sure which terminology is being used)

   I would like to set up a check whether you are currently viewing the main site or a sub site, something like;

   if ( blog_ID = 1 ) {
   You are on the main site
   } else {
   You are on a sub site
   }

   I found this code in the codex;

   <?php
   $blog_details = get_blog_details(1);
   echo 'Blog '.$blog_details->blog_id.' is called '.$blog_details->blogname.'.';
   ?>

   So what I need is to get the ID and insert it where that code suggests a check for Blog ID 1's details.

   Thanks in advance!

   / Carl-Johan

   <?php
   global $blog_id;
   if ($blog_id == 1) {
      //do something
   } else {
      //do something else
   }
   ?>

   A, cheers man!

   Now I feel really embarrassed :)

   Is there a list of the globals anywhere that I've missed? I haven't been using MU at all, and I'm building my first MS.

   Thanks again!

   This should probably help:
   http://codex.wordpress.org/WPMU_Global_Variables

   If you need to retrieve multiple variables all at once, use the $current_site or $current_blog objects. For example:
   

   global $current_site;
   if($current_site->id == 1) {
      echo $current_site->path;
   }

   Hi,
   I'm trying to use the code above
   

   <?php
   global $blog_id;
   if ($blog_id == 4) {
      //First blog links
   } else {
      //Default links <a href="http:\\example.com>example</a>
   }
   ?>

   Does it work in WP3 as well?

   I would like to display different links on the top for each blog in my Network, but it's not displaying anything.

   Please help!!! Thanks

   If you have exactly what you've pasted, jumust, you actually need to include some links after the comment
   

   //First blog links
   echo '<a href="http://example.com>example</a>';

   and so on.

   Thanks David but I can't display what I want.
   Here it is what I have:
   

   <div id="header" class="col-full">
   
    <div class="toplinks">
   <?php
   global $blog_id;
   if ($blog_id == 4) {
      //First blog links
   echo '<a href="http://example.com>custom link</a>';
   } else {
      //Default links <a href="http:\\example.com>dafault</a>
   }
   ?>
   </div>

   So "toplinks" tag goes above the logo, but I get this: see here
   I assume it displays the blog title and tagline because of global $blog_id; but it doesn't display any links above the logo within the "toplinks" tag.

   Any helps is much appreciate

   Hi,
   I think I had just missed " after example.com and also the \\ after the http: are definitely wrong.
   Anyway thanks so much
