Getting variable values from nested twig / symfony custom template

Mar 12, 2015 php symfony

This post is more than 18 months old. Since technology changes too rapidly, this content may be out of date (but that's not always the case). Please remember to verify any technical or programming information with the current release.

Today, I was working with a custom form themed symfony / twig project. The previous developer had developed a bootstrap based theme (yes, this is an older Symfony project at this moment - I think this is a bundled theme now). I was struggling with the block field_row item. Inside of this, there was a call to form_label passing in just the form view again. I was setting a custom label on the form_row() call in the main template, but nothing was happening.

I should mention… I’m just learning this particular integration, plus this is slightly old code, so I may be partially right in my entry. If I have something wrong, please comment! I’d love to learn. But, I wanted to post this because I couldn’t find the answer myself.

I had the following:

edit.html.twig

{{ form_row(form.myItem, {'label': 'My special label'}) }}

It wasn’t grabbing my output in the custom template. The template excerpt looked like this…

{% block field_row %}
  <div class="{{ div_class }}">
    {{ form_label(form) }}
    <div class="controls">
      {{ form_widget(form, _context) }}
      {{ form_errors(form) }}
    </div>
  </div>
{% endblock field_row %}

In this case, the form variable passed to form_label did not have my custom variable on it. Caveat: it looks like its a form render view object, but I don’t quite yet follow why this matters… Anyway, I tried using form.get('label') but that didn’t work.

Turns out, the _context array had the values for this particular element. So, I modified:

{{ form_label(form, _context['label']) }}

Yay! That got the standard label - or the custom label I set. Success.
