Overriding Default FOSUserBundle Templates

As you start to incorporate FOSUserBundle into your application, you will probably find that you need to override the default templates that are provided by the bundle. Although the template names are not configurable, the Symfony2 framework provides two ways to override the templates of a bundle.

  1. Define a new template of the same name in the app/Resources directory
  2. Create a new bundle that is defined as a child of FOSUserBundle

Example: Overriding The Default layout.html.twig

It is highly recommended that you override the Resources/views/layout.html.twig template so that the pages provided by the FOSUserBundle have a similar look and feel to the rest of your application. An example of overriding this layout template is demonstrated below using both of the overriding options listed above.

Here is the default layout.html.twig provided by the FOSUserBundle:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8" />
    </head>
    <body>
        <div>
            {% if is_granted("IS_AUTHENTICATED_REMEMBERED") %}
                {{ 'layout.logged_in_as'|trans({'%username%': app.user.username}, 'FOSUserBundle') }} |
                <a href="{{ path('fos_user_security_logout') }}">
                    {{ 'layout.logout'|trans({}, 'FOSUserBundle') }}
                </a>
            {% else %}
                <a href="{{ path('fos_user_security_login') }}">{{ 'layout.login'|trans({}, 'FOSUserBundle') }}</a>
            {% endif %}
        </div>

        {% for key, message in app.session.getFlashes() %}
        <div class="{{ key }}">
            {{ message|trans({}, 'FOSUserBundle') }}
        </div>
        {% endfor %}

        <div>
            {% block fos_user_content %}
            {% endblock fos_user_content %}
        </div>
    </body>
</html>

As you can see its pretty basic and doesn't really have much structure, so you will want to replace it with a layout file that is appropriate for your application. The main thing to note in this template is the block named fos_user_content. This is the block where the content from each of the different bundle's actions will be displayed, so you must make sure to include this block in the layout file you will use to override the default one.

The following Twig template file is an example of a layout file that might be used to override the one provided by the bundle.

{% extends 'AcmeDemoBundle::layout.html.twig' %}

{% block title %}Acme Demo Application{% endblock %}

{% block content %}
    {% block fos_user_content %}{% endblock %}
{% endblock %}

This example extends the layout template from a fictional application bundle named AcmeDemoBundle. The content block is where the main content of each page is rendered. This is why the fos_user_content block has been placed inside of it. This will lead to the desired effect of having the output from the FOSUserBundle actions integrated into our applications layout, preserving the look and feel of the application.

a) Define New Template In app/Resources

The easiest way to override a bundle's template is to simply place a new one in your app/Resources folder. To override the layout template located at Resources/views/layout.html.twig in the FOSUserBundle directory, you would place you new layout template at app/Resources/FOSUserBundle/views/layout.html.twig.

As you can see the pattern for overriding templates in this way is to create a folder with the name of the bundle class in the app/Resources directory. Then add your new template to this folder, preserving the directory structure from the original bundle.

b) Create A Child Bundle And Override Template

Note:

This method is more complicated than the one outlined above. Unless  you are
planning to override the controllers as well as the templates, it is recommended
that you use the other method.

As listed above, you can also create a bundle defined as child of FOSUserBundle and place the new template in the same location that is resides in the FOSUserBundle. The first thing you want to do is override the getParent method to your bundle class.

// src/Acme/UserBundle/AcmeUserBundle.php
<?php

namespace Acme\UserBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class AcmeUserBundle extends Bundle
{
    public function getParent()
    {
        return 'FOSUserBundle';
    }
}

By returning the name of the bundle in the getParent method of your bundle class, you are telling the Symfony2 framework that your bundle is a child of the FOSUserBundle.

Now that you have declared your bundle as a child of the FOSUserBundle, you can override the parent bundle's templates. To override the layout template, simply create a new file in the src/Acme/UserBundle/Resources/views directory named layout.html.twig. Notice how this file resides in the same exact path relative to the bundle directory as it does in the FOSUserBundle.

After overriding a template in your child bundle, you must clear the cache for the override to take effect, even in a development environment.

Overriding all of the other templates provided by the FOSUserBundle can be done in a similar fashion using either of the two methods shown in this document.

Configuring A Templating Engine Other Than Twig

You can configure a templating engine other than Twig using the bundle's configuration. Below is an example configuration for using the PHP templating engine.

fos_user:
    # ...
    template:
        engine: php

The FOSUserBundle only provides default templates for the Twig templating engine, so you will have to create all of the templates that you are using. The names and locations will be the same except that the file extension will be .php instead of .twig
