I would like to add a custom logo to my entire blog network’s dashboard. I went trough a recipe on smashing magazine and got this code:
//hook the administrative header output
add_action('admin_head', 'my_custom_logo');
function my_custom_logo() {
echo '
<style type="text/css">
#header-logo { background-image: url('.get_bloginfo('template_directory').'/images/custom-logo.gif) !important; }
</style>
';
}
Where do I add it? I think that I should add it in functions.php
. But if so I should add the code to every theme in my mutlinetworks.
Does any one have idea to add it to the entire network?
I should also able to set only for a particular sub and not to entire network If I change my mind in future 🙂
Thank you!
If you want this logo to show up across your network sites regardless of the theme I’d advise you to create a new PHP file inside
wp-content/mu-plugins
(create the directory if it doesn’t exist) and drop that code inside the new file. You can name your file whatever you like – for examplemy-network-tweaks.php
. That file will be loaded automatically as a plugin on all of the sites.And if you’d like to override this image for a particular site you can make that function pluggable. Like this:
Note that I’ve changed the image path because we want it to point to a single file for the whole network. Using
get_bloginfo('template_directory')
would cause it to load the image from the theme directory.If you want to override the image for a single site, just use Tom J Nowell’s code renaming the function to
override_my_custom_logo
You might check out the White Label CMS plugin to automate this for you.
Place this in functions.php and add a file custom-logo.gif ( 32×32 pixels ) in an images subfolder of your theme.
