iterable

1.7

The iterable test was added in Twig 1.7.

iterable checks if a variable is an array or a traversable object:

1
2
3
4
5
6
7
8
9
{# evaluates to true if the foo variable is iterable #}
{% if users is iterable %}
    {% for user in users %}
        Hello {{ user }}!
    {% endfor %}
{% else %}
    {# users is probably a string #}
    Hello {{ users }}!
{% endif %}
