Blog ID always returns 1

If I remember it correctly, WP developers have some discussions on the site id that always return to 1 for some reason.

Have you tried using $blog_id as global?

Yes I have. Still can’t figure this out.

You can get the current blog id:

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

Works fine.

Yeah, that works for me too, but the function I am using is within the functions.php file in a parent theme. See code below:

switch_to_blog($blog_id);

Uh. At the risk of not understanding it, why are you saying ‘Get the ID of the blog I’m on, and the SWITCH to that blog ID’?

Because it always returns 1. When I hard code the switch to an ID of 2 it displays the correct content, which is why I was looking for a way for the function to pick up the blog ID I am viewing.

Where are you putting this code? I get the feeling I’m missing something really obvious that solves everything ??

I have a multisite setup. I am using a parent theme for all the sites with my set up. I have set up a ‘product selector’ widget within my parent theme that retrieves parent and child pages using AJAX.

The first drop down within my product selector gets the parent pages, then retrieves the child pages based on the ID of the parent page. The function within my functions.php (in the parent theme) file is used to retrieve the child pages but because the blog_id always returns 1 it is never finding the correct child pages for the correct website/blog.

Try using:

global $wpdb;
switch_to_blog( $wpdb->blogid );
...
restore_current_blog();
