Twig check elements of array are in another array

Question

I'm trying to check in twig if any element of one array are set in other array. Example:

I have user.roles with ['ROLE_ADMIN','ROLE_MANAGER'] and I have the product.roles with ['ROLE_ADMIN','ROLE_USER'].

I want to check (in Twig) if any user.roles are in product.roles, like:

{{ user.roles[0] is product.roles|keys }}

But with each element of user.roles in the same function.

Does anyone know how?

You could use the filter filter to do this, but guessing it would be better to move this to PHP / TwigExtension

{% if user.roles |filter((role) => role in product.roles) | length > 0 %}
    Can do something with the post
{% else %}
    Access denied
{% endif %}

Thanks @DarkBee!, that works! But finally I make a Symfony Voter to can use the is_granted in twig and in the controller :). But your solution works so well too :)

Glad to hear you solved it this way. The aproach you took is a far better one than doing this in pure twig

Use a for loop:

{% for role in user.roles %}
  {% if role in product.roles|keys %}
    do something...
  {% endif %}
{% endfor %}

If two or more roles are granted you would have multiple output with this
