Twig how to check the existence of an array key?

Question

symfony

I check as follows

{% if myKey in items|keys %}
        {{ items[myKey].name }}
{% endif %}

The problem is that if there is no such key, then it refers to it in the if body, and gives an error that the access to a non-existent key. How to avoid it?

Answer 1

Try{% if items[myKey] is defined %}

Answer 2

{% if items[myKey]|default(false) %}
