I'm learning symfony2 and like it very much (migrating from ZendFramework 1.x) but I'm stuck now with twig templating. Can you point me to the right direction?
My application has many customers and each has some customization (mostly templates, but also controllers, etc.).
I try to achieve this by bundle inheritance / I created ClientBundle which inherits from BaseBundle holding all basic code and templates... it works as I need for everything bud templates. When I create template in ClientBundle it overlays the template from BaseBundle and I cannot get access from the ClientBundle template to the original template from BaseBundle. I would like to extend the parent template, not overlay it... is this impossible?
Thank you!
Using the standard Symfony extends notation to reference a parent's bundle template results in fatal error. Symfony interprets your template reference to BaseBundle as ChildBundle as a result of bundle inheritance causing a function nesting level exception.
You can reference the parent's bundle template file directly using the following notation:
{% extends "#Client/Foo/bar.html.twig" %}
in replacement for:
{% extends "ClientBundle:Foo:bar.html.twig" %}
Twig's FilesystemLoader splits the reference string into namespace (Client) and path (Foo/bar.html.twig). Namespace is your bundle name without the Bundle suffix. Full path for each namespace is resolved by concatenating default <bundle_path>/Resources/views/ with supplied path.
The standard command in twig template for extention is:
{% extends 'BaseBundle::yourTemplate.html.twig' %}
You probably use the same name for template in your child bundle (you probably have a yourTemplate.html.twig in both your parent and your child bundle so the child template overrides the parent). In this case, you can rename your child template (yourTemplate2.html.twig) and then extend the child template from parent. More about bundles inheritance and twig templates extentions:

I need to override a template from third-party bundle by following one of the Symfony's built-in conventions. The Symfony documentation talks about them:
To override the bundle template, just copy index.html.twig template from the bundle to app/Resources/AcmeBlogBundle/views/Blog/index.html.twig (the app/Resources/AcmeBlogBundle directory won't exist, so you'll need to create it). You're now free to customize the template.
You can also override templates from within a bundle by using bundle inheritance. For more information, see How to Use Bundle Inheritance to Override Parts of a Bundle.
While this approach may work, it can be overly complicated if you only need to override a small portion of the template (e.g. some blocks). Additionally, if the third-party bundle updates its own template, your version of the template may become outdated and require updates to stay current with the latest changes.
This is what I've tried to do without success:
{# app/Resources/AcmeBlogBundle/views/Blog/layout.html.twig #}
{% extends '#AcmeBlog/Blog/layout.html.twig' %}
{% block title %}My Default Title{% endblock %}
The above code doesn't work. It breaks after reaching the maximum execution time when I've accessed this page and the clear cache command never ends.
Why it doesn't works and how to achieve it without copying the entire parent template from the third-party bundle?

{# app/Resources/AcmeBlogBundle/views/Blog/layout.html.twig #}
{% extends '#AcmeBlog/Blog/layout.html.twig' %}
{% block title %}My Default Title{% endblock %}
The reason comes from Twig's paths and namespaces auto-configuration between bundles, their children and Symfony's path convention. By default Symfony/Bundle/TwigBundle assign the same Twig's namespace (AcmeBlog) for all paths, following this order:
# config.yml
twig:
paths:
# Auto-configuration behind the scenes for TwigBundle extension:
# (1st) if AcmeBlogChildBundle has as parent to AcmeBlogBundle
'src/AcmeBlogChildBundle/Resources/views': AcmeBlog
# (2nd) Path to override bundles (Symfony's convention)
'app/Resources/AcmeBlogBundle/views': AcmeBlog
# (3rd) third-party bundle
'vendor/acme/blog-bundle/Resources/views': AcmeBlog
That means, if you need to render the #AcmeBlog/Blog/layout.html.twig template, Twig try to find it in all paths (in the order has been defined) whose namespace matches AcmeBlog.
So to override it, you had to create this template (/Blog/layout.html.twig) in (1st) or (2nd) paths. But, if you're extending from #AcmeBlog/Blog/layout.html.twig at the same time (thinking about extends from the original template) then Twig performs the same previous procedure, causing a circular template reference (infinite loop) and never reach the (3rd) path.
How to achieve it without copy the entire parent template from the third-party bundle?
Symfony's built-in workaround
Let's define a different Twig's namespace for this third-party bundle in twig paths configuration:
# config.yml
twig:
paths:
# (4th) third-party bundle alias.
# The path can be relative to project or real path
vendor/acme/blog-bundle/Resources/views: AcmeBlogOriginal
Later, use the namespace alias to avoid circular reference when you're overriding a third-party template that extends from the original:
{# app/Resources/AcmeBlogBundle/views/Blog/layout.html.twig #}
{% extends '#AcmeBlogOriginal/Blog/layout.html.twig' %}
{% block title %}My Default Title{% endblock %}
Thus, you're able to override blocks instead the whole template. Even should work out-of-the-box as it's about Twig's paths only.
Since Symfony 3.4 this issue has been solved as built-in feature.

I have Entity Product with productImages. ManyToOne relationship.
I want to override product images twig. To do it, I created easy_admin folder under view and inside ProductImage folder, then edit and new twigs for test.
It is not overriding at all. Product is overridden easily is this way, but ProductImage is not.
Don't you think in theory it should work like this?
If not, please give me some clue how to override, change collection type twig.
I want to have nice bootstrap table instead current one.
Thanks
If anyone is curious how to override collection type:
in config.yml add:
easy_admin:
design:
form_theme: '/custom_form_layout.html.twig'
Then in custom_form_layout.html.twig write:
{% extends 'EasyAdminBundle:form:bootstrap_3_horizontal_layout.html.twig' %}
Or extend your base form whatever it is.
after that override block
{% block collection_row %}<div>I Love Symfony! (or just use parent())</div>{% endblock collection_row %}
I'm trying to override the FOSUserBundle Templates as show here:
https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/doc/overriding_templates.md
I used the second method, I created my own bundle and put the templates in
myBundle/Resources/Views/Security/login.html.twig
and
myBundle/Resources/Views/Registration/register.html.twig.
both templates start with:
{% extends "::nologbase.html.twig" %}
where nologbase.html.twig is defined in app/Resourcer/views.
well, the first one (login) is correctly displayed but the second one (register) shows row html with no css.
I cleared the cache and I also tried to display only the extended template and compared the source code. it is exactly the same!
any idea?
thanks
I've just installed FOSUserBundle and I'm trying to override the templates to use my own custom layout.
I have a bundle, BMCmsBundle, that has a layout.html.twig file in
src/BM/CmsBundle/Resources/views/layout.html.twig
Looking through the docs, I have created the following file:
app/Resources/FOSUserBundle/views/layout.html.twig
How do I then use my own template, i.e. CSS/jS?
I've tried in the FOS layout.html.twig file to use the following:
{% extends 'BMCmsBundle::layout.html.twig' %}
But once again, this doesn't seem to work, any ideas why?
Thanks
After creating your new layout at
app/Resources/FOSUserBundle/views/layout.html.twig
Make sure you also clear your cache:
php app/console cache:clear
It is the opposite.
Your layout in BMCmsBundle has to extend the one in app/Resources with the command :
{% extends "::layout.html.twig" %}
I want to override the default SonataAdmin Template.
I create a standard_layout.html.twig in my Namespace/bundle/resources/views
(same structur, same file name, same content)
I copied all the content of the source template in my target template, i just edit some part of the target off course....and nothing
thanks for your help
Bye
You have the solution of bundle heritance http://symfony.com/doc/current/cookbook/bundles/inheritance.html which allows, not only override templates but methods too.
Or you have http://symfony.com/doc/2.0/book/templating.html#overriding-bundle-templates which focusing only on templates.
With this last, you can try to create :
app/Resources/SonataAdminBundle/views/CRUD/base_show_field.html.twig
