I use Symfony 2 with Twig and my question is pretty straightforward:
In a view I want to extend one of the layouts based on a variable. If the variable is false
I want to extend UdoWebsiteBundle::layout.html.twig
and if it's true
I want to extend UdoWebsiteBundle::layout_true.html.twig
.
Here is the code I tried:
{% block layout_extender %}
{% if intro == 'false' %}
{% extends 'UdoWebsiteBundle::layout.html.twig' %}
{% else %}
{% extends 'UdoWebsiteBundle::layout_true.html.twig' %}
{% endif %}
{% endblock %}
I get this error:
Multiple extends tags are forbidden in "UdoWebsiteBundle:home:home.html.twig" at line 7
Is there any other way to achieve this?
Try this one:
{% extends intro == 'false'
? 'UdoWebsiteBundle::layout.html.twig'
: 'UdoWebsiteBundle::layout_true.html.twig' %}
