Is there a way to check if a value exists in an array in twig?

Question

Done some searching on this but can't quite find what I'm looking for. Most threads are regarding keys.

I want to know if there is a way to test if a value exists in a twig array.

It should be able to check whether the value is a variable, object or an array.

So for example:

{% if value not in array %}
    .... do someting
{% endif %}

Any suggestions welcome.

Answer 1

Like you said, to test if a value exists in a Twig array you'd do:

{% if myValue in ['apples', 'oranges'] %}
    {# do something... #}
{% endif %}

To check whether the value is an array or object you could use the iterable test:

{% if myValue is iterable %}
    {# myValue is an array or object #}
{% else %}
    {# myValue is probably a string #}
{% endif %}

To be certain, you might be best coming out of Twig using a plugin Template Variable and doing it directly in PHP.

Craft 3.7.15 onwards you can use is array twig test. More info https://github.com/craftcms/cms/blob/develop/CHANGELOG.md
