I wish to remind to my plugin customers that the plugin is enabled however solely on product web page (dashboard), i’ve got here throughout the $pagenow international variable:

international $pagenow;
$pagenow != 'publish.php'; // This shall be proven on "regular posts" too

How am i able to add a discover alert solely on product web page? That is what i’ve for the time being:

add_action('admin_notices', operate () {
    if (!is_admin()) {
        return;
    }

    $title = __e('Your plugin is enabled');
    $div = '<div class="discover notice-info is-dismissible"><p>%s</p></div>';

    $pluginPath = 'path-to/my-plugin.php';
    if (is_plugin_active($pluginPath)) {
        echo sprintf($div, $title);
    }
});
