Twig: set a variable inside a loop, use it outside that loop

Question

I'm trying to define `driverid`, using `set`, as a var in `for driver in assigned.driver` cycle for use later. See below what I'm doing: ``` {% for key, assigned in pgn %} {{ assigned.imei }} {{ assigned.description }} {% for driver in assigned.driver %} {{ driver.driver.id }} {# check if driver.driver.id has values testing purposes - delete me #} {% set driverid = driver.driver.id %} {% if driver.driver.name != "" %} {% if driver.driver.name %} {{ driver.driver.name }} {% else %} - {% endif %} {% endif %} {% endfor %}

Accepted Answer

As they say here, this is not a bug, it's a feature: variables defined inside a loop are scoped to that loop.

But don't worry, you can define the var outside the loop and assign it inside, like this:

```
{% set driverid = '' %} {# <-- add this line: default empty value #}

{% for driver in assigned.driver %}
     ...
     {% set driverid = driver.driver.id %}
```

this should be enough to make it work.
