How to Add Custom Admin Notices in WordPress: 2 Reliable Methods

As experienced WordPress developers, we've relied on admin notices countless times to communicate critical updates, errors, or tips directly in the dashboard. These built-in alerts from WordPress core, themes, and plugins help users stay informed without disrupting their workflow.

Why Use Admin Notices in WordPress?

Admin notices deliver errors, warnings, successes, and key info right where admins work. Whether you're a site owner guiding clients, a plugin author signaling updates, or managing a multi-author site, they provide targeted guidance.

Pro tip: Use them sparingly to avoid overwhelming users. Now, let's dive into adding your own with authority-backed methods we've tested across hundreds of sites.

Method 1: Add Custom Notices Manually with Code

This hands-on approach offers ultimate flexibility. New to code? See our guide on how to add code snippets to WordPress.

Add this to your theme's functions.php or a custom plugin:

function general_admin_notice() {
    global $pagenow;
    if ( $pagenow == 'options-general.php' ) {
        echo '<div class="notice notice-warning is-dismissible"><p>This notice appears on the settings page.</p></div>';
    }
}
add_action( 'admin_notices', 'general_admin_notice' );

Here's how it looks:

The $pagenow global detects the page. Wrap content in a <div class="notice [type] [is-dismissible]">: use notice-error, notice-warning, notice-success, or notice-info. The is-dismissible class adds a close button.

Customize further with conditions, like showing only to authors on the dashboard:

function author_admin_notice() {
    global $pagenow;
    if ( $pagenow == 'index.php' ) {
        $user = wp_get_current_user();
        if ( in_array( 'author', (array) $user->roles ) ) {
            echo '<div class="notice notice-info is-dismissible"><p>Click on Posts to start writing.</p></div>';
        }
    }
}
add_action( 'admin_notices', 'author_admin_notice' );

Result:

Experiment with roles, capabilities, or plugins for endless variations.
