Problem
In navbar.html.twig I have a block that looks like this:
//navbar.html.twig
{% block back_link %}{% endblock %}
This navbar is included by my base.html.twig.
//base.html.twig
{% include navbar.html.twig %}
And then my page template extends the base.
//page.html.twig
{% extends base.html.twig %}
...
{% block back_link %} Things i want in the navbar. {% endblock %}
But the things I want in the navbar don't show up in the navbar, because it's included by the base, so there's no parent/child relationship there.
Question
What's a good (or any) way to let me override a block in an included template in an extended template?
if you understand your idea right, you want to have some reusable content for a navbar, separated to navbar.html.twig that will possible to use in several templates?
So you can do it with "use" http://twig.sensiolabs.org/doc/tags/use.html
In navbar.html.twig
//navbar.html.twig
{% block back_link %}{% endblock %}
In base.html.twig.
//base.html.twig
{% use '::navbar.html.twig' %}
{{ block('back_link') }}
In page.html.twig
{% extends '::base.html.twig' %}
{% block back_link %} Things i want in the navbar. {% endblock %}

It is something pretty simple to be done outside of twig but here I am not even sure it is possible. This is the case:
Have base.html.twig. header.html.twig, home.html.twig.
#home.html.twig
{% extends 'base.html.twig' %}
{% block body %}
<h1>MY HTML</h1>
{% endblock %}
#base.html.twig
....some html here
{% block header%}{% endblock %}
{% block body %}{% endblock %}
....some more html here
#header.html.twig
{% extends 'base.html.twig' %}
{% block header %}
some here things that have to shown on every page through base.html.twig
{% endblock %}
I think it is pretty straight forward scenario but still my header doesn't show anywhere. As I understood from the documentation it is not working because this is how blocks work. It renders the page i am calling from my controller (home.html.twig) and the extended by it (base.html.twig). But wont call the header as well. So! How should I call the header on every page ?
To add the header on all pages just put include see example
{% block header %}
{% include 'header.html.twig' %}
{% endblock %}
I have a base.html.twig with the basic html.
In the 'base' I have a {% block body %}{% endblock %} and a {% block javascript %}{% endblock %}
I call a 'form.html.twig' file from the Controller and the template extends the base.html.twig.
The 'form' contains the <form> and </form> tags and can contain a random numbers of sub templates/form elements:
'{% block body %}
{% for template in templates %}
{% embed template %}{% endembed %}
{% endfor %}
{% endblock %}'
The 'template' is perhaps a customer.html.twig, confirm.html.twig, vehicle.html.twig etc. etc. and they all have {% block body %} and {% block javascript %} - now for the question:
The content in the template files aren't moved to the blocks body/javascript. How do I get twig/symfony to move the content in the template files to the respective areas in the 'base.html.twig'?
Thank you for your time.
You want to use the use twig tag instead of the embed tag like this
{% use template %}

I have a simple Twig template, were I wan to override a block from the include.
base.html.twig:
{% block razem %}
{% include '_ga.code.html.twig' %}
{% endblock %}
_ga.code.html.twig:
{% block wspolny %}
should be common
{% endblock %}
{% block googleAnalitics %}
for overridden
{% endblock %}
success.html.twig
{% extends 'base.hmtl.twig' %}
{% block razem %}
{{ parent('wspolny') }}
{% block googleAnalitics %}
overriding part
{% endblock %}
{% endblock %}
Where is the error? http://twigfiddle.com/jsuk6a
I expected to render something like this:
should be common
overriding part
In twig you can not override blocks in a include. For this you have to use embed, but have to do this in the using template, not in the base one.
base.html.twig:
{% block razem %}{% endblock %}
_ga.code.html.twig:
{% block wspolny %}
should be common
{% endblock %}
{% block googleAnalitics %}
for overridden
{% endblock %}
success.html.twig
{% extends 'base.hmtl.twig' %}
{% block razem %}
{% embed '_ga.code.html.twig' %}
{% block googleAnalitics %}
overriding part
{% endblock %}
{% endembed %}
{% endblock %}
I think that the best way to override a block and reuse some others is to extend the base template where you want to perform an overriding (maybe adding some code to the pre-existing one) and to apply the so called horizontal reuse:
Horizontal reuse is an advanced Twig feature that is hardly ever needed in regular templates. It is mainly used by projects that need to make template blocks reusable without using inheritance.
Starting from that point, you should simply use the base.html.twig template and extend _ga.code.html.twig as follows:
success.html.twig
{% extends '_ga.code.hmtl.twig' %}
{# Simply use base - without overriding #}
{% use 'base.hmtl.twig' %}
{% block googleAnalitics %}
overriding part
{% endblock %}
If you want to make an overload of a single block you could also use the parent() function; so, you can add some other information to an extended block.
If you need something more complex you should go for dynamic inheritance.
{% extends ['base.html.twig', '_ga.code.html.twig'] %}
Is it possible to add a javascript block in a Sonata Block View like this ?
{% extends sonata_block.templates.block_base %}
{% block block %}
<!-- html -->
{% endblock %}
{% block javascripts %}
// javascript code
{% endblock %}
I couldn't make it works in this way as javascript block doesn't exist in template block base but present in my layout.
i have a lot of time programming in PHP, but im doing my first steps in Symfony.
Im try write Twigg templates, i have a public template in app/Resources/view/public.html.twig.
This file contains: http://pastebin.com/T1KGMfXL.
Now, in CloudBundle, have a base.html.twig:
{% extends '::public.html.twig' %}
{% block main %}
<div class="login_page">
<div class="login_box">
{% block content %} {% endblock %}
</div>
</div>
{% endblock %}
And the content in another twig file. For example, login.html.twig
{% extends 'base.html.twig' %}
{% block content %}
....
{% endblock %}
In the Controller, when an user try http://cloud.man.local/app.php/login:
public function staticAction($sitio)
{
// in this case, $sitio contains "login"
return $this->render("CloudBundle:Default:$sitio.html.twig");
}
So, the problem is that, only shows the footer, not show the content.
Any ideas ?.
You want to override a block which is inside another block, so in your case I think you should try this in the another twig files:
{% block main %}
{{ parent() }}
{% block content %} YOur content {% endblock %}
{% endblock %}
see http://twig.sensiolabs.org/doc/functions/parent.html
Hope it's helpful.
Best regard.
