Output variables in October are automatically escape, the |raw
filter marks the value as being "safe" and will not be escaped if raw is the last filter applied.
{# This variable won't be escaped #}
{{ variable|raw }}
Be careful when using the raw
filter inside expressions:
{% set hello = '<strong>Hello</strong>' %}
{% set hola = '<strong>Hola</strong>' %}
{{ false ? '<strong>Hola</strong>' : hello|raw }}
{# The above will not render the same as #}
{{ false ? hola : hello|raw }}
{# But renders the same as #}
{{ (false ? hola : hello)|raw }}
