[frozzare]

Example using Sage theme.

// Today
remove_filter('template_include', 'papi_template_include');
add_filter('template_include', function ($orginal) {
    $new = papi_template_include($orginal);

    if ($orginal === $new) {
        return $orginal;
    }

    echo template($new);
    return get_stylesheet_directory().'/index.php';
});

// After (example)
// $template = 'pages/video.php'
add_filter('papi_template_include', function ($orginal) {
    $new = papi_template_include($orginal);

    if ($orginal === $new) {
        return $orginal;
    }

    echo template($new);
    return get_stylesheet_directory().'/index.php';
} );
