``iterable`` ============ .. versionadded:: 1.7 The iterable test was added in Twig 1.7. ``iterable`` checks if a variable is an array or a traversable object: .. code-block:: jinja {# 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 %}
