Is possible in Symfony2 to change the layout (using twig) at runtime?
The layout should change based on a record fetched from a database, so I am thinking to implement a sort of LayoutManager that decides what layout to load for every request, but still I can't find a way to do this at runtime.
Twig template
{% extends myLayoutName %}
{% block my_block_with_content %}
Some content here
{% endblock %}
Controller
public function myAction() {
$layoutName = '...'; // Calculate layout name
return $this->render(
'AcmeAcmeBundle::template_name.html.twig',
['myLayoutName' => $layoutName]
);
}

In my controller, I return the entity so that my twig template can use it like so:
return $this->render('review/index.html.twig',[
"list" => $applications
]);
$applications is a query that returns the object I'm looking for:
$applications = $this->getDoctrine()->getRepository(ApplicationQueue::class)->findBy(
array("assignment_mod_user" => $this->getUser()->getId())
);
And within my twig, I use the dump function to see if it's retrieving what I'm looking for. This is what is returned:
As you can see, there are two entities associated to this entity. In twig when I tired to do this, it failed to retrieve the data within:
{% for application in list %}
{{application.application.[whateverhere]}}
{% endfor %}
How do I access the entities within an entity in twig when the data is already being pushed? The current output returns the error of:
Neither the property "application" nor one of the methods "application()", "getapplication()"/"isapplication()"/"hasapplication()" or "__call()" exist and have public access in class "App\Entity\ApplicationQueue".
You need to add an accessor to get the value of $application. This property is currently not accessible from outside the ApplicationQueue class.
class ApplicationQueue
{
protected $application;
public function getApplication(): CreatorApplication
{
return $this->application;
}
}
You have tu put double curly braces around your variable, like that :
{{ application.application.name }}
Look at the twig doc :
{% for user in users %}
<li>{{ user.username|e }}</li>
{% endfor %}
Im trying my first project using symfony2 + twig. I created basic twig template with defined blocks. It basically looks like this
{% block content %}
some content...
{% endblock %}
{% block footer %}
{{ footer.content}}
{% endblock %}
I want footer to be same for all pages. Footer is loaded from DB and its set in controller. I wanted inherit from template described above to other pages but I have to always set footer in controller otherwise variable is not defined.
My questions is if exists any 'nice' way how to set footer variable for multiple templates inherited from parent template?
The solution : Embedding Controllers
In some cases, you need to do more than include a simple template.
Suppose you have a sidebar in your layout that contains the three most
recent articles. Retrieving the three articles may include querying
the database or performing other heavy logic that can't be done from
within a template.
The solution is to simply embed the result of an entire controller
from your template. First, create a controller that renders a certain
number of recent articles:
Controller
// src/AppBundle/Controller/ArticleController.php
namespace AppBundle\Controller;
// ...
class ArticleController extends Controller
{
public function recentArticlesAction($max = 3)
{
// make a database call or other logic
// to get the "$max" most recent articles
$articles = ...;
return $this->render(
'article/recent_list.html.twig',
array('articles' => $articles)
);
}
}
View
{# app/Resources/views/article/recent_list.html.twig #}
{% for article in articles %}
<a href="/article/{{ article.slug }}">
{{ article.title }}
</a>
{% endfor %}
Layout
{# app/Resources/views/base.html.twig #}
{# ... #}
<div id="sidebar">
{{ render(controller(
'AppBundle:Article:recentArticles',
{ 'max': 3 }
)) }}
</div>
you can do with one of the following, 'write a custom Twig Extension'
<?php
namespace AppBundle\Extension;
class MyTwigExtension extends \Twig_Extension
{
private $em;
private $conn;
public function __construct(\Doctrine\ORM\EntityManager $em) {
$this->em = $em;
$this->conn = $em->getConnection();
}
public function getFunctions()
{
return array(
'users' => new \Twig_Function_Method($this, 'getUsers'),
);
}
public function getUsers()
{
$sql = "SELECT * FROM users ORDER BY accountname";
return $this->conn->fetchAll($sql);
}
public function getName()
{
return 'smproc4_twig_extension';
}
}
Register an Extension as a Service
services:
my.twig.extension:
class: AppBundle\Extension\MyTwigExtension
tags:
- { name: twig.extension }
arguments:
em: "#doctrine.orm.entity_manager"
Using the custom Extension
Hello {{ name }}!
<ul>
{% for user in users() %}
<li>{{ user.accountname }}</li>
{% endfor %}
</ul>

How to Write a custom Twig Extension
Creating an Extension
In my symfony2 application I created a dashboard which currently consists of many navigation elements.
Now I am trying to split those elements into several bundles.
This is the code I have:
{# app/Resources/views/base.html.twig #}
{# ... #}
{% block body %} {% endblock %}
{# ... #}
Then in the ProfileBundle:
{# src/MyApp/ProfileBundle/Resources/views/Dashboard/index.html.twig #}
{% block body %}
<p>Heading</p>
<ul>
{% block dashboardNavi %} {% endblock %}
</ul>
{% block %}
edit: The controller:
class DashboardController extends Controller
{
public function indexAction()
{
return $this->render('MyAppProfileBundle:Dashboard:index.html.twig', array());
}
}
The routing:
pricecalc_profile_dashboad_security:
pattern: /dashboard
defaults: {_controller: MyAppProfileBundle:Dashboard:index }
That template is rendered correctly, when my route "/dashboard" is loaded.
What I now'd like to do, is extend that dashboardNavi-Block in multiple Bundles without changing the route from my ProfileBundle.
Each of those Bundles brings it`s own routes and controllers for custom actions, but all bundles should extend that one block to add links for their custom actions to the dashboard screen.
What I have so far is:
{# src/MyApp/ProfileNewsletterBundle/Resources/views/Dashboard/indexNewsletter.html.twig #}
{% extends 'MyAppProfileBundle:Dashboard:index.html.twig' %}
{% block dashboardNavi %}
{{ parent() }}
<li>Test</li>
{% endblock %}
but that template is never rendered.
edit 2:
Maybe my understanding of how symfony is working in terms of template inheritance is kind of wrong. I'll specify what I am trying to do.
I got one Bundle (DashboardBundle) which consists of an own route, controller, view etc. The view contains two blocks - like navigation and dashboard.
Now, I would like to have those two blocks extended by some other Bundles - just adding new navigation items and shortcuts on that dashboard and navigation block.
I would like to do those enhancements without modifying my Dashboard-Bundle - if that is possible at all.
When finished, I will have 16 Bundles, each providing own functionality in own Controllers - and they should just be linked on that dashboard.
Is it possible to have the dashboard-view extended that way without modifying the view itself?
I finally managed to fix that after having understood how symfony works in extending controllers and views.
I added a new Controller:
{# src/MyApp/ProfileNewsletterBundle/Controllers/DashboardController.php #}
class DashboardController extends Controller {
public function indexAction()
{
return $this->render('ProfileNewsletterBundle:Dashboard:index.html.twig', array());
}
}
modified the bundle ProfileNewsletterBundle to let the method getParent return ProfileBundle,
and modified the view:
{% extends 'ProfileBundle:Dashboard:index.html.twig' %}
{% block dashboardNavi %}
<li>Test</li>
{% endblock %}
That seems to work fine so far.
Thank you all for spending your time on that.
I was wondering how should i approach this problem. In sonata admin dashboard i have users and i would like to preview users profile pictures in thumbnails of a ListMapper. I'm new to symfony and still a bit confused trying to wrap my head around these concepts.
You need to create a custom template where you display the image of your user, i will assume that your Entity User as a Picture Entity which has a path method that gives the image URL :
picture.html.twig
{% extends 'SonataAdminBundle:CRUD:base_list_field.html.twig' %}
{% block field %}
<div>
{% if object.picture != null %}
<img src="{{ object.picture.path }}">
{% else %}
<span>No picture</span>
{% endif %}
</div>
{% endblock %}
You know have to use this template in your list
class UserAdmin extends Admin
{
protected function configureListFields(ListMapper $listMapper)
{
$listMapper
->addIdentifier('id')
->add('picture', null, array(
'template' => 'ApplicationSonataAdminBundle:User:picture.html.twig'
));
}
}
Documentation is available here : http://sonata-project.org/bundles/doctrine-orm-admin/master/doc/reference/list_field_definition.html#custom-template
one separated entity, -no user-, where I have added one media, this for me worked
in admin configureListFields
->add('media', 'string', array('template' => 'SonataMediaBundle:MediaAdmin:list_image.html.twig'))
Is there a way to change default options for form fields globally in symfony2?
More specifically, I want to change the render of ALL datetime fields to use single_text instead of the default choice widget.
Can it be done? Or do I need to implement a custom type and set the default in there, like for example the birthdate type?
I prefer an option that leads to minimal changes in the codebase.
The post is old, but you can use an alternative method, overriding the DateType symfony class ...
service.yml
services:
form.type.date:
class: "YourApp\YourBundle\Form\DateType"
tags:
- { name: "form.type", alias: "date" }
DateType.php
<?php
namespace YourApp\YourBundle\Form;
use Symfony\Component\Form\Extension\Core\Type\DateType as SymfonyDateType;
use Symfony\Component\OptionsResolver\OptionsResolver;
class DateType extends SymfonyDateType
{
/**
* {#inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
parent::configureOptions( $resolver );
$resolver->setDefault( 'widget', 'single_text' );
}
}
You can check if the service is taken by container
$ ./app/console debug:container | grep form.type.date
form.type.date YourApp\YourBundle\Form\DateType
form.type.datetime Symfony\Component\Form\Extension\Core\Type\DateTimeType
You have to define a form theme.
It's very easy and requires only a little bit coding time. First of all, you have to know which block to customize; in that case, you can do something like
{% block my_data_widget %}
{% spaceless %}
{% if type is defined and type == 'date' %}
// do all your customization
{% else %}
// don't know ...
{% endif %}
{% endspaceless %}
{% endblock form_widget_simple %}
Now that you have defined this snippet of code, you can use it into your main template (or whatever you use into your form views) in that way
{% form_theme form 'YourBundle:Form:myDataWidget' %}
Last but not least important, you have to place your form theme into Resources/views folder. In my example, your path will be Resources/views/Form/myDataWidget
Update
Did you tried with
{% set type = type|default('single_text') %}
or something like that?
