how can i get $dynamic_template_folder from database in config file

Answer 1

That's rather an odd question. Normally your config is defined before you do any logic, so the only way of doing that in the config file is to open a connection to your database, get the value and append it to the /../../app/views/templates/.

A much better way of doing that would be in you DI, when you define you view service. Also consider caching the database calls or storing the data in a session if possible to avoid unnecessary calls.

$di->setShared('view', function () use ($di, $configuration) {
    $templateDir = $di->db->…; // Load the necessary details from the db.

    $view = new View();
    $view->setViewsDir($configuration->viewsDir . $templateDir);
    $view->registerEngines([…]);
    return $view;
});
