I want to create simple star rating function.
I want to to write in Twig template {{ star (9) }} and it should show image (or images) and text rating (9/10).
To pass variables to Twig I use in my controller:
$this->get('twig')->addGlobal('current_url', $this->currentUrl);
and it works fine.
So in the same controller I use code:
$function = new \Twig_SimpleFunction('star', function () {
echo "test";
});
$this->get('twig')->addFunction($function);
and in Twig template I use:
{{ star }}
to display it. But it doesn't work at all (no error but also no result).
Question: How should it be written to make it work? And also - is it possible this function this way that I assign some variables to Twig and simple include another Twig file in which stars will be created in loop?
I'm Symfony beginner. I saw How can I create a symfony twig filter? but for me it's to complex at the moment - if possible I don't want to create new services / classes and so on to create simple function.
