您可以使用admin_notices 为此采取的行动：

function wpa_admin_notice() {
    $screen = get_current_screen();
    if( \'your_post_type\' == $screen->post_type
        && \'edit\' == $screen->base ){
        ?>
        <div class="updated">
            <p>Here is some text</p>
        </div>
        <?php
    }
}
add_action( \'admin_notices\', \'wpa_admin_notice\' );
