How to get current template name in a TWIG function

Question

let\'s say I have created a custom twig function: templateName.

$twig = new Twig_Environment($loader);
$twig->addFunction(\'templateName\', new Twig_Func         


        

Answer 1

For everyone who needs an answer to the initial question, I found a solution that twig itself is using in the Twig_Error class.

protected function guessTemplateInfo()
{
    $template = null;
    foreach (debug_backtrace() as $trace) {
        if (isset($trace['object']) && $trace['object'] instanceof Twig_Template && 'Twig_Template' !== get_class($trace['object'])) {
            $template = $trace['object'];
        }
    }

    // update template filename
    if (null !== $template && null === $this->filename) {
        $this->filename = $template->getTemplateName();
    }

    /* ... */

best regards!
