FrameworkBundle Configuration ("framework")

FrameworkBundle Configuration ("framework")

This reference document is a work in progress. It should be accurate, but all options are not yet fully covered.

The FrameworkBundle contains most of the "base" framework functionality and can be configured under the framework key in your application configuration. This includes settings related to sessions, translation, forms, validation, routing and more.

Configuration

secret

type: string required

This is a string that should be unique to your application. In practice, it's used for generating the CSRF tokens, but it could be used in any other context where having a unique string is useful. It becomes the service container parameter named kernel.secret.

http_method_override

2.3The http_method_override option was introduced in Symfony 2.3.

type: Boolean default: true

This determines whether the _method request parameter is used as the intended HTTP method on POST requests. If enabled, the Request::enableHttpMethodParameterOverride gets called automatically. It becomes the service container parameter named kernel.http_method_override. For more information, see How to Use HTTP Methods beyond GET and POST in Routes.

ide

type: string default: null

If you're using an IDE like TextMate or Mac Vim, then Symfony can turn all of the file paths in an exception message into a link, which will open that file in your IDE.

Symfony contains preconfigured urls for some popular IDEs, you can set them using the following keys:

  • textmate
  • macvim
  • emacs
  • sublime

New in version 2.3.14: The emacs and sublime editors were introduced in Symfony 2.3.14.

You can also specify a custom url string. If you do this, all percentage signs (%) must be doubled to escape that character. For example, if you have installed PhpStormOpener and use PHPstorm, you will do something like:

  • YAML
    1
    2
    3
    # app/config/config.yml
    framework:
        ide: "pstorm://%%f:%%l"

    <!-- app/config/config.xml -->
    <?xml version="1.0" encoding="UTF-8" ?>
    <container xmlns="http://symfony.com/schema/dic/services"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:framework="http://symfony.com/schema/dic/symfony"
        xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd
            http://symfony.com/schema/dic/symfony http://symfony.com/schema/dic/symfony/symfony-1.0.xsd">
    
        <framework:config ide="pstorm://%%f:%%l" />
    </container>
    
  • PHP

    // app/config/config.php
    $container->loadFromExtension('framework', array(
        'ide' => 'pstorm://%%f:%%l',
    ));
    

Of course, since every developer uses a different IDE, it's better to set this on a system level. This can be done by setting the xdebug.file_link_format in the php.ini configuration to the url string. If this configuration value is set, then the ide option will be ignored.

test

type: Boolean

If this configuration parameter is present (and not false), then the services related to testing your application (e.g. test.client) are loaded. This setting should be present in your test environment (usually via app/config/config_test.yml). For more information, see Testing.

trusted_proxies

type: array

Configures the IP addresses that should be trusted as proxies. For more details, see How to Configure Symfony to Work behind a Load Balancer or a Reverse Proxy.

2.3CIDR notation support was introduced in Symfony 2.3, so you can whitelist whole subnets (e.g. 10.0.0.0/8, fc00::/7).

form

csrf_protection

session

name

type: string default: null

This specifies the name of the session cookie. By default it will use the cookie name which is defined in the php.ini with the session.name directive.

gc_probability

type: integer default: 1

This defines the probability that the garbage collector (GC) process is started on every session initialization. The probability is calculated by using gc_probability / gc_divisor, e.g. 1/100 means there is a 1% chance that the GC process will start on each request.

gc_divisor

type: integer default: 100

See gc_probability.

gc_maxlifetime

type: integer default: 1440

This determines the number of seconds after which data will be seen as "garbage" and potentially cleaned up. Garbage collection may occur during session start and depends on gc_divisor and gc_probability.

save_path

type: string default: %kernel.cache.dir%/sessions

This determines the argument to be passed to the save handler. If you choose the default file handler, this is the path where the session files are created. For more information, see Configuring the Directory where Session Files are Saved.

You can also set this value to the save_path of your php.ini by setting the value to null:

        ),
    ));
    

serializer

enabled

type: boolean default: false

Whether to enable the serializer service or not in the service container.

For more details, see How to Use the Serializer.

templating

assets_base_urls

default: { http: [], ssl: [] }

This option allows you to define base URLs to be used for assets referenced from http and ssl (https) pages. A string value may be provided in lieu of a single-element array. If multiple base URLs are provided, Symfony will select one from the collection each time it generates an asset's path.

For your convenience, assets_base_urls can be set directly with a string or array of strings, which will be automatically organized into collections of base URLs for http and https requests. If a URL starts with https:// or is protocol-relative (i.e. starts with //) it will be added to both collections. URLs starting with http:// will only be added to the http collection.

assets_version

type: string

This option is used to bust the cache on assets by globally adding a query parameter to all rendered asset paths (e.g. /images/logo.png?v2). This applies only to assets rendered via the Twig asset function (or PHP equivalent) as well as assets rendered with Assetic.

For example, suppose you have the following:

  • Twig
    1
    <img src="{{ asset('images/logo.png') }}" alt="Symfony!" />
    
  • PHP
    1
    <img src="<?php echo $view['assets']->getUrl('images/logo.png') ?>" alt="Symfony!" />
    

By default, this will render a path to your image such as /images/logo.png. Now, activate the assets_version option:

  • YAML
    1
    2
    3
    4
    # app/config/config.yml
    framework:
        # ...
        templating: { engines: ['twig'], assets_version: v2 }

    13
    <!-- app/config/config.xml -->
    <?xml version="1.0" encoding="UTF-8" ?>
    <container xmlns="http://symfony.com/schema/dic/services"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:framework="http://symfony.com/schema/dic/symfony"
        xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd
            http://symfony.com/schema/dic/symfony http://symfony.com/schema/dic/symfony/symfony-1.0.xsd">
    
        <framework:templating assets-version="v2">
            <!-- ... -->
            <framework:engine>twig</framework:engine>
        </framework:templating>
    </container>
    
  • PHP
    1
    2
    3
    4
    5
    6
    7
    8
    // app/config/config.php
    $container->loadFromExtension('framework', array(
        // ...
        'templating'      => array(
            'engines'        => array('twig'),
            'assets_version' => 'v2',
        ),
    ));
    

Now, the same asset will be rendered as /images/logo.png?v2 If you use this feature, you must manually increment the assets_version value before each deployment so that the query parameters change.

It's also possible to set the version value on an asset-by-asset basis (instead of using the global version - e.g. v2 - set here). See Versioning by Asset for details.

You can also control how the query string works via the assets_version_format option.

assets_version_format

type: string default: %%s?%%s

This specifies a sprintf pattern that will be used with the assets_version option to construct an asset's path. By default, the pattern adds the asset's version as a query string. For example, if assets_version_format is set to %%s?version=%%s and assets_version is set to 5, the asset's path would be /images/logo.png?version=5.

Note

All percentage signs (%) in the format string must be doubled to escape the character. Without escaping, values might inadvertently be interpreted as Service Parameters.

Tip

Some CDN's do not support cache-busting via query strings, so injecting the version into the actual file path is necessary. Thankfully, assets_version_format is not limited to producing versioned query strings.

The pattern receives the asset's original path and version as its first and second parameters, respectively. Since the asset's path is one parameter, you cannot modify it in-place (e.g. /images/logo-v5.png); however, you can prefix the asset's path using a pattern of version-%%2$s/%%1$s, which would result in the path version-5/images/logo.png.

URL rewrite rules could then be used to disregard the version prefix before serving the asset. Alternatively, you could copy assets to the appropriate version path as part of your deployment process and forgot any URL rewriting. The latter option is useful if you would like older asset versions to remain accessible at their original URL.

profiler

enabled

default: true in the dev and test environments

The profiler can be disabled by setting this key to false.

2.3The collect option was introduced in Symfony 2.3. Previously, when profiler.enabled was false, the profiler was actually enabled, but the collectors were disabled. Now, the profiler and the collectors can be controlled independently.

collect

default: true

This option configures the way the profiler behaves when it is enabled. If set to true, the profiler collects data for all requests. If you want to only collect information on-demand, you can set the collect flag to false and activate the data collectors by hand:

1
$profiler->enable();

translator

enabled

type: boolean default: false

Whether or not to enable the translator service in the service container.

fallback

default: en

This option is used when the translation key for the current locale wasn't found.

For more details, see Translations.

logging

2.6The logging option was introduced in Symfony 2.6.

default: true when the debug mode is enabled, false otherwise.

When true, a log entry is made whenever the translator cannot find a translation for a given key. The logs are made to the translation channel and at the debug for level for keys where there is a translation in the fallback locale and the warning level if there is no translation to use at all.

property_accessor

magic_call

type: boolean default: false

When enabled, the property_accessor service uses PHP's magic __call() method when its getValue() method is called.

throw_exception_on_invalid_index

type: boolean default: false

When enabled, the property_accessor service throws an exception when you try to access an invalid index of an array.
