Everything you see in EasyAdmin, from the layout of this table, to even how each individual field is rendered, is controlled by a template. EasyAdmin has a bunch of templates and we can override all of them!

We looked at these a bit earlier. Let's dive back into vendor/easycorp/easyadmin-bundle/src/Resources/views/. There's a lot of good stuff here, like layout.html.twig. This is the base layout file for every page. A few minutes ago, we also saw content.html.twig. This is a nice layout template that you can extend if you're creating a custom page inside of EasyAdmin.

In crud/, we see the templates for the individual pages and in field/, there's a template that controls how every field type is rendered.

In many of these templates, you'll see things like ea.templatePath('layout'). To understand that more deeply, hit "shift+shift" and open up a core class that we explored earlier called TemplateRegistry.

Internally, EasyAdmin maintains a map from a template "name" to an actual template path. So when you see something like ea.templatePath('layout'), that's going to use TemplateRegistry to figure out to load @EasyAdmin/layout, where @EasyAdmin is a Twig alias that points to this views/ directory.

Overriding a Core Template

With that in mind, here's our goal: I want to add a footer to the bottom of every page. Look again at layout.html.twig. Near the bottom, let's see... search for "footer". There we go! This has a block called content_footer. So if you define a content_footer, then it will get dumped right here. Let's override the layout.html.twig template and do that!

There are two ways to override a template. The first is to use Symfony's normal system for overriding templates that live inside of a bundle. You do that by creating a file in a very specific path. Inside of templates/, create a directory called bundles/... and inside of that, another directory with the name of the bundle: EasyAdminBundle. Now, match whatever path from the bundle that you want to override. Since we want to override layout.html.twig, create a new file called layout.html.twig.

But, hmm. I don't really want to override this entirely. I want to extend it. And, we can do that! Add {% extends %}, with @EasyAdmin/layout.html.twig. The only problem is that, by creating a templates/bundles/EasyAdminBundle/layout.html.twig file, when Symfony looks for the @EasyAdmin/layout.html.twig template, it will now use our file! In other words, we're extending ourselves!

To tell Symfony that we want to use the original template, add an exclamation point in front.

{% extends '@!EasyAdmin/layout.html.twig' %}
// ... lines 2 - 6

Perfect! Below, add {% block content_footer %} and {% endblock %}... with a nice little message inside.

// ... lines 1 - 2
{% block content_footer %}
Made with 🤍 by the guys and gals at SymfonyCasts
{% endblock %}

Let's try it! Refresh any page and... hello footer!

Overriding a Field Template

So that's the first way to override a template. The second is even more powerful because it allows us to control exactly when we want our overridden templates to be used. Like, you can override a template across your entire admin or just for one crud section. Let me close a few files.

So for our next trick, let's override the template that's used to render id fields. We're going to add a little key icon next to the ID.

Open up IdField.php. Ok, it sets its template name to crud/field/id. In the template registry... here it is... that corresponds to this template. So the template that renders IdField is Resources/views/crud/field/id.html.twig.

Instead of using the first method to override this - which would work - let's do something different.

Copy this template and create our override template... which could live anywhere. How about in templates/admin/field/... and call it id_with_icon.html.twig. Paste the contents... and I'll put the icon right before the id.

{# @var ea \EasyCorp\Bundle\EasyAdminBundle\Context\AdminContext #}
{# @var field \EasyCorp\Bundle\EasyAdminBundle\Dto\FieldDto #}
{# @var entity \EasyCorp\Bundle\EasyAdminBundle\Dto\EntityDto #}
{# this template is used to display Doctrine entity primary keys #}
<span class="fa fa-key"></span> {{ field.formattedValue }}

At this moment, this will not, yet be used. To activate it globally, go to DashboardController: you can configure template override paths down in configureCrud(). Check it out: ->overrideTemplate() where the first argument is the name of the template: that's the thing you see inside TemplateRegistry or IdField. So whenever EasyAdmin renders crud/field/id, we'll now have it point to admin/crud/field/id_with_icon.html.twig.

// ... lines 1 - 24
class DashboardController extends AbstractDashboardController
// ... lines 27 - 79
public function configureCrud(): Crud
return parent::configureCrud()
// ... lines 83 - 85
->overrideTemplate('crud/field/id', 'admin/field/id_with_icon.html.twig');
// ... lines 88 - 126

How cool is that? Let's try it! Refresh and... whoops... let me get rid of my extra crud/ path. Now let's try it! And... yes! Awesome! We see the key icon across the entire system.

Re-Using the Parent Template

But we can make this even better. The id template is super simple... since it just prints the formatted value. But sometimes the original template might do more complex stuff. Instead of repeating all of that in our template, we can include the original template. So quite literally include()... and I'll start typing id.html.twig... and let that autocomplete.

// ... lines 1 - 4
<span class="fa fa-key"></span>
{{ include('@EasyAdmin/crud/field/id.html.twig') }}

At the browser... we get the same result.

Next, let's talk about permissions: How we can deny access to entire CRUD controllers or specific actions based on the user's role.
