Thank you in advance for your help on this

  • Thank you for the link, but the very reason of this post is because I previously posted my question on this thread but it has been deleted because it was off topi

  • Just drop it in the same folder as WordPress - that's your root (unless you've got it installed in a subfolder).

  • @theDeadedic thank you for your answer, but in a context of multi site install, what would be considered as root. let say that I have 10 sites under the network belt, where would you put those 10 different favicon?

  • So, just to be clear, each site has a different favicon?

I would use a rewrite to map requests for /favicon.ico to /icons/example.com.ico:

RewriteCond %{REQUEST_URI} ^/favicon\.ico
RewriteCond %{SERVER_NAME} ^(www\.)?([a-z0-9]+)
RewriteCond %{DOCUMENT_ROOT}/icons/%2.ico -f
RewriteRule . /icons/%2.ico [L]

Note the regex for line #2 depends on your set-up - is each website its own domain, or a subdomain/subdirectory of a primary domain?

I would also place a default favicon in the root, which will get pulled if no favicon exists in /icons for the current site.

Another approach is to print the links in the <head>.
The only caveat is that the following is not working in Sub-directory installs, only in Sub-domain.
Somehow get_current_blog_id is only returns the ID 1 in when define('SUBDOMAIN_INSTALL', false);.

<?php
/**
 * Plugin Name: Multisite Favicons
 * Description: Favicons should be stored in http://example.com/icons/domain_name.ico | If the site is subsite.example.com, the favicon should be subsite.ico
 **/

add_filter( 'wp_head', 'multisite_favicons_wpse_38903' );

function multisite_favicons_wpse_38903()
{ 
    // This function returns true if not Multisite
    if( is_main_site() ) 
        return;

    global $current_site;

    $details = get_blog_details( get_current_blog_id() );
    $blogname = 
        ( is_subdomain_install() ) 
        ? str_replace( '.' . $current_site->domain, '', $details->domain ) 
        : $details->path;

    printf(
        "<link rel='shortcut icon' href='%s/icons/%s.ico' type='image/x-icon'/>\n", 
        site_url(),
        $blogname
    );
}
