Accessing array values using array key from Twig

问题:

Does anyone know how (of if it's even possible!) to do this in Twig? I can't see anything in the documentation as to whether it's possible.

The PHP array is structured as below:

$data['data']['a']['title'] = 'Title 1'; $data['data']['a']['title'] = 'Title 2'; $data['data']['b']['title'] = 'Title 3';

Twig template code below:

{% for letter in 'a'..'z' %}     {{ letter }}     
         {% for key, item1 in data %}             {% for item2 in item1 %}                  
{{ item2[key].title }}
              {% endfor %}         {% endfor %}                     
 {% endfor %}

Edit: After further investigation, it appears the attribute (see http://twig.sensiolabs.org/doc/functions/attribute.html) function should do the job but I am unsure as to how to use it in these circumstances.

Many thanks

Have you just tried this:

attribute(item2, key).title
