Hi, I wonder if is possibile to pass a variable to a snippet by reference. Something like: snippet('article-snippet', array('playlist' => &$playlist)); Thanks

Äh, why? You pass a variable to a function by reference to be able to modify the variable…

I need to pass $playlist from the main page to a snippet; the snippet should append more values to $playlist and then passing it back to the main page.

Template: <?php $playlist = $pages; snippet('test', ['playlist' => $playlist]) ?> <?php dump($playlist) ?> Snippet: <?php $playlist = $playlist->add(page('somepage')); return $playlist; ?>

Thanks. But it doesn’t work for me. Anyway, I think it’s better (and cleaner) to store the values some other way, sessions for example…

[image] daizumi: snippet(‘test’, [‘playlist’ => $playlist) ?> There’s a typo, should be <?php snippet('test', ['playlist' => $playlist]) ?> For me it still works.

For me it doesn’t. And it’s nothing to do with your typo - I was testing with my own variables. I just get the same old content.

Maybe it only works with that example, I doesn’t seem to work with an array. Why don’t you store the variable in the session?

I was testing with strings anyway. Yes, I could use the session I guess, but why use the session for something that I don’t need throughout the session - only during one page load. Isn’t there a more elegant way?
