Hello,
In my template I use:
<?php $filteredPages = $page->parent()->children()->listed()->not($page)->filterBy('cat', $category, ',')->limit(3); ?>
(...)
All work correctly, but I’m trying to move all my html in a snippet, and when I do it, have an error: Undefined variable: category
I also tried to use it in a controller, but did not work.
Thank you for advices.
If you move stuff from a template to a snippet, you have to pass your variables along to the snippet, if they are not defined inside the snippet.
<?php
$category = 'whatever'; // the variable is probably define in your controller, just putting it here for clarity
snippet('your_snippet', ['category' => $category]) ?>
Yes, $category is defined in the parent controller, and passing the variable along the snippets works just fine.
Thank you.
