* how to get page tempalte name by code wordpress 

add_action('wp_head', 'show_template');
function show_template() {
    global $template;
    echo basename($template);
}

or just use it directly in template (I tend to echo in footer.php in HTML comment)


<?php global $template; echo basename($template); ?>
