is_multisite(); Support for WordPress 3.0

4 Views

Looking for a variable to use to differentiate between sites in a WordPress 3.0 Multisite installation. I saw the function “is_multisite();” in some blogs, but not sure if its supported yet. I have one theme I’d like to use on all the Network’s sites, but need a way to use conditions between them.

Thanks for the help.

  1. This article dicusses a few different techniques for determining if the site is in a Multisite installation. Below is a cleaned up version of their custom function:

    function yourtheme_is_multsite() {
    global $wpmu_version;
    if (function_exists('is_multisite'))
        return is_multisite();
    return !empty($wpmu_version));
}
