PHP Kirby Use 2 variables in 1 Snippet

Question

I'm really new to Kirby and PHP and I try to use 2 variables in a Snippet. This is my Code right now

<div class="container">

<h2><?= $variable1 ?></h2>


<?php
foreach (page('blogs')
  ->children()
  ->listed()
  ->filterBy('tags', 'variable2', ',')
  ->flip() as $subpage) :

  snippet('blogkarte', ['subpage' => $subpage]);
?>

<?php endforeach ?>

I understand how to use the $title method for Variable1, but it don't work with Variable2

<?php snippet('blogkarten', ['variable1' => 'MYTEXT"', 'variable2' => "MYTEXT"]) ?>

This is the way I tried, but it didn't worked...

I hope somebody can help me

Answer 1

Right now, the second parameter of your filterBy() method is a hard-coded string literal: PHP is not seeing is as a 'variable named $variable2', but rather as the literal string "variable2".

If you're correctly passing a variable named $variable2 to your snippet, and you want to use it as the second parameter in your filterBy() method, you just need to do this:

->filterBy('tags',$variable2,',')
