If you enable automatic output escaping, Twig will only consider the
content to be safe when capturing chunks of text.
Note that differently from PHP in Twig loops are scoped, therefore a variable
declared inside a for-in loop isn't accessibile outside the loop itself.
The variable must be declared before the loop to be accessibile elsewhere.
.. code-block:: jinja
.. note::
{% set foo = "" %}
{% for item in list %}
{% set foo = item %}
{% endfor %}
{{ dump(foo) }}
Note that loops are scoped in Twig; therefore a variable declared inside a
``for`` loop is not accessible outside the loop itself:
.. code-block:: jinja
{% for item in list %}
{% set foo = item %}
{% endfor %}
{# foo is NOT available #}
If you want to access the variable, just declare it before the loop:
.. code-block:: jinja
{% set foo = "" %}
{% for item in list %}
{% set foo = item %}
{% endfor %}
{# foo is available #}
