<p>Admin Notice is a very simple plugin that allows you to display custom notices in the WordPress admin that is visible to all users.</p>
<p>Control over the notice text and styling is available from the plugin’s settings page.</p>
<p>Developers can use the <code>admin_notice_enable</code> hook to control the notice’s visibility on a more granular level. The following example demonstrates how to show the notice only in the “Posts” area of the admin.</p>
<pre><code>add_filter('admin_notice_enable', function($enabled) {

    $screen = get_current_screen();

    if (isset($screen->post_type) && $screen->post_type !== 'post') {
        $enabled = false;
    }

    return $enabled;

}, 10, 1);
</code></pre>
