Show parts of template to specific roles

Mano

I want to show parts of a template to specific roles.

I'm able to retrieve the user role with user.roles however I can't find a function in twig like in_array to check the roles of a user against a list of allowed roles.

my code just so far is:

{% for role in user.roles %}
{% if role == 0 or role ==7 or role == 9 %}
{# restricted content #}
{% endif %}
{% endfor %}

however the problem with this code (besides being not very elegant I think) is that if the current user has multiple roles (like admin has the root and everyone roles), the content will be shown "n" times for every assigned role.

Is there a (better) solution?
Thanks

ok I partially solved the issue by creating a variable flag that is set to true if the role in the if loop is true.
I know it isn't very nice but it works.

here's the new code

{% set flag = false %}
{% for role in user.roles %}
{% if role == 0 or role ==7 or role == 9 %}
{% set flag = true %}
{% endif %}
{% endfor %}

{% if flag == true %}
{# restricted content #}
{% endif %}

I corrected the if loop because I thought I accessed keys instead by default the for loop access to values, and the if wasn't correct.

the correct if is the following (and it works really, this time):

{% if role == "root" or role == "developer" or role == "portal-admin" %}

I think you do not need to iterate over the roles array with

{% for role in user.roles %}
    ....

I think you can just check if one of your roles is in the roles array

{% if "root" in user.roles or "developer" in user.roles or "portal-admin" in user.roles %}
    {# restricted content #}
{% endif %}

thank you. indeed this is a better solution.
