How to use in_array and isset in twig template?

Question

This part:

<?php if (isset($quantity_taxation_curr) && in_array($currency['code'], $quantity_taxation_curr)) { ?>

to become in twig format, I tried with this:

{% if isset(quantity_taxation_curr) AND in_array(currency['code'], quantity_taxation_curr) %}

But it's not correct.

Answer 1

Try this:

{% if quantity_taxation_curr is defined and currency['code'] in quantity_taxation_curr %}

Answer 2

Try this out

{% if quantity_taxation_curr is defined and 'code' in quantity_taxation_curr %}
...
{% endif %}
