# `sandbox`

Warning

The `sandbox` tag is deprecated as of Twig 3.15. Use the `sandboxed` option of the `include` function instead.

The `sandbox` tag can be used to enable the sandboxing mode for an included template, when sandboxing is not enabled globally for the Twig environment:

    {% sandbox %}
        {% include 'user.html.twig' %}
    {% endsandbox %}

Warning

The `sandbox` tag is only available when the sandbox extension is enabled (see the Twig for Developers chapter).

Note

The `sandbox` tag can only be used to sandbox an include tag and it cannot be used to sandbox a section of a template. The following example won’t work:

    {% sandbox %}
        {% for i in 1..2 %}
            {{ i }}
        {% endfor %}
    {% endsandbox %}
