钩入load-{screen_id} 并检查$_GET[\'trashed\'] 变量为1或以上。

add_action(\'load-edit.php\',\'wpse_trashed_redirect\');
function wpse_trashed_redirect(){
    $screen = get_current_screen();
    if(\'edit-page\' == $screen->id){
        if( isset($_GET[\'trashed\']) &&  intval($_GET[\'trashed\']) >0){
            $redirect = add_query_arg(array(\'page\'=>\'custom_page_oder\', \'trashed\' => false, \'ids\' => false ));
            wp_redirect($redirect);
            exit();
        }
    }
}
