Email All Site Admins

Not really, since there’s not a setting on usermeta that says ‘This ID is an admin’ – The admins are a per-site settings.

You could do something like this: https://wplifeguard.com/how-to-add-custom-alerts-to-a-wordpress-dashboard/

And I think there are plugins out there that do that too.

Thanks! The custom alerts says it’s multisite capable, but the code provided says to add to the theme’s function file. Am I missing something? I haven’t found any plugins for this.

With my WordPress multisite I need to be able to alert subsite admins with updates and changes.

Put it in a file in your mu-plugins folder ??

I’ve never created my own file for the mu-plugins folder before. Can I create a file called whatever.php and place a code solution from https://wplifeguard.com/how-to-add-custom-alerts-to-a-wordpress-dashboard/?

https://halfelf.org/2012/mu-plugins-are-good/ can explain it ??

I added a file called admin_alert.php to my mu-plugins directory and put the following code in it. When I refresh the site page the page displays white in FF and I get an unknown server error in Chrome.

<?php
if (current_user_can('administrator')) {
	function addDashboardAlert() { ?>
	<script type="text/javascript">
	$j = jQuery;
	$j().ready(function(){
		$j('.wrap > h2').parent().prev().after('<div class="update-nag">This is a test alert for admins only. Do with it what you want.</div>');
	});
	</script>
	<?php } add_action('admin_head','addDashboardAlert');
}
?>

I tried the first code on wplifeguard’s site and it works. Any idea to why the alert based on user level does not work (code above)?
