FrameworkBundle Configuration (“framework”)¶

The FrameworkBundle contains most of the “base” framework functionality and can be configured under the framework key in your application configuration. When using XML, you must use the http://symfony.com/schema/dic/symfony namespace.

This includes settings related to sessions, translation, forms, validation, routing and more.

Tip

The XSD schema is available at http://symfony.com/schema/dic/symfony/symfony-1.0.xsd.

secret¶

type: string required

This is a string that should be unique to your application and it’s commonly used to add more entropy to security related operations. Its value should be a series of characters, numbers and symbols chosen randomly and the recommended length is around 32 characters.

In practice, Symfony uses this value for generating the CSRF tokens, for encrypting the cookies used in the remember me functionality and for creating signed URIs when using ESI (Edge Side Includes).

This option becomes the service container parameter named kernel.secret, which you can use whenever the application needs an immutable random string to add more entropy.

As with any other security-related parameter, it is a good practice to change this value from time to time. However, keep in mind that changing this value will invalidate all signed URIs and Remember Me cookies. That’s why, after changing this value, you should regenerate the application cache and log out all the application users.

http_method_override¶

New in version 2.3: The 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 method gets called automatically. It becomes the service container parameter named kernel.http_method_override.

See also

For more information, see How to Use HTTP Methods beyond GET and POST in Routes.

Caution

If you’re using the AppCache Reverse Proxy with this option, the kernel will ignore the _method parameter, which could lead to errors.

To fix this, invoke the enableHttpMethodParameterOverride() method before creating the Request object:

// web/app.php

// ...
$kernel = new AppCache($kernel);

Request::enableHttpMethodParameterOverride(); // <-- add this line
$request = Request::createFromGlobals();
// ...

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.

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

YAML

# app/config/config.yml
framework:
    trusted_proxies:  [192.0.0.1, 10.0.0.0/8]

XML

<!-- 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 trusted-proxies="192.0.0.1, 10.0.0.0/8" />
</container>

PHP

// app/config/config.php
$container->loadFromExtension('framework', array(
    'trusted_proxies' => array('192.0.0.1', '10.0.0.0/8'),
));

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 use PHPstorm on the Mac OS platform, you will do something like:

YAML

# app/config/config.yml
framework:
    ide: "phpstorm://open?file=%%f&line=%%l"

XML

<!-- 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="phpstorm://open?file=%%f&line=%%l" />
</container>

PHP

// app/config/config.php
$container->loadFromExtension('framework', array(
    'ide' => 'phpstorm://open?file=%%f&line=%%l',
));

Tip

If you’re on a Windows PC, you can install the PhpStormProtocol to be able to use this.

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 setting 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).

See also

For more information, see Testing.

default_locale¶

type: string default: en

The default locale is used if no _locale routing parameter has been set. It is available with the Request::getDefaultLocale method.

See also

You can read more information about the default locale in Setting a Default Locale.

trusted_hosts¶

type: array | string default: array()

A lot of different attacks have been discovered relying on inconsistencies in handling the Host header by various software (web servers, reverse proxies, web frameworks, etc.). Basically, everytime the framework is generating an absolute URL (when sending an email to reset a password for instance), the host might have been manipulated by an attacker.

See also

You can read “HTTP Host header attacks” for more information about these kinds of attacks.

The Symfony Request::getHost() method might be vulnerable to some of these attacks because it depends on the configuration of your web server. One simple solution to avoid these attacks is to whitelist the hosts that your Symfony application can respond to. That’s the purpose of this trusted_hosts option. If the incoming request’s hostname doesn’t match one in this list, the application won’t respond and the user will receive a 500 response.

YAML

# app/config/config.yml
framework:
    trusted_hosts:  ['acme.com', 'acme.org']

XML

<!-- 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>
        <trusted-host>acme.com</trusted-host>
        <trusted-host>acme.org</trusted-host>
        <!-- ... -->
    </framework>
</container>

PHP

// app/config/config.php
$container->loadFromExtension('framework', array(
    'trusted_hosts' => array('acme.com', 'acme.org'),
));

Hosts can also be configured using regular expressions (e.g. .*\.?acme.com$), which make it easier to respond to any subdomain.

In addition, you can also set the trusted hosts in the front controller using the Request::setTrustedHosts() method:

// web/app.php
Request::setTrustedHosts(array('.*\.?acme.com$', '.*\.?acme.org$'));

The default value for this option is an empty array, meaning that the application can respond to any given host.

See also

Read more about this in the Security Advisory Blog post.

form¶

enabled¶

type: boolean default: false

Whether to enable the form services or not in the service container. If you don’t use forms, setting this to false may increase your application’s performance because less services will be loaded into the container.

This option will automatically be set to true when one of the child settings is configured.

Note

This will automatically enable the validation.

See also

For more details, see Forms.

csrf_protection¶

See also

For more information about CSRF protection in forms, see CSRF Protection.

enabled¶

type: boolean default: true if form support is enabled, false otherwise

This option can be used to disable CSRF protection on all forms. But you can also disable CSRF protection on individual forms.

If you’re using forms, but want to avoid starting your session (e.g. using forms in an API-only website), csrf_protection will need to be set to false.

field_name¶

Caution

The framework.csrf_protection.field_name setting is deprecated as of Symfony 2.4, use framework.form.csrf_protection.field_name instead.

type: string default: "_token"

The name of the hidden field used to render the CSRF token.

esi¶

See also

You can read more about Edge Side Includes (ESI) in Using Edge Side Includes.

enabled¶

type: boolean default: false

Whether to enable the edge side includes support in the framework.

You can also set esi to true to enable it:

YAML

# app/config/config.yml
framework:
    esi: true

XML

<!-- 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>
        <esi />
    </framework:config>
</container>

PHP

// app/config/config.php
$container->loadFromExtension('framework', array(
    'esi' => true,
));

fragments¶

See also

Learn more about fragments in the HTTP Cache article.

enabled¶

type: boolean default: false

Whether to enable the fragment listener or not. The fragment listener is used to render ESI fragments independently of the rest of the page.

This setting is automatically set to true when one of the child settings is configured.

path¶

type: string default: '/_fragment'

The path prefix for fragments. The fragment listener will only be executed when the request starts with this path.

profiler¶

enabled¶

New in version 2.2: The enabled option was introduced in Symfony 2.2. Prior to Symfony 2.2, the profiler could only be disabled by omitting the framework.profiler configuration entirely.

type: boolean default: false

The profiler can be enabled by setting this option to true. When you are using the Symfony Standard Edition, the profiler is enabled in the dev and test environments.

Note

The profiler works independently from the Web Developer Toolbar, see the WebProfilerBundle configuration on how to disable/enable the toolbar.

collect¶

New in version 2.3: The 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.

type: boolean 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 (unless you configure otherwise, like a custom matcher). If you want to only collect information on-demand, you can set the collect flag to false and activate the data collectors manually:

$profiler->enable();

only_exceptions¶

type: boolean default: false

When this is set to true, the profiler will only be enabled when an exception is thrown during the handling of the request.

only_master_requests¶

type: boolean default: false

When this is set to true, the profiler will only be enabled on the master requests (and not on the subrequests).

dsn¶

type: string default: 'file:%kernel.cache_dir%/profiler'

The DSN where to store the profiling information.

See also

See Switching the Profiler Storage for more information about the profiler storage.

username¶

type: string default: ''

When needed, the username for the profiling storage.

password¶

type: string default: ''

When needed, the password for the profiling storage.

lifetime¶

type: integer default: 86400

The lifetime of the profiling storage in seconds. The data will be deleted when the lifetime is expired.

matcher¶

Matcher options are configured to dynamically enable the profiler. For instance, based on the ip or path.

See also

See How to Use Matchers to Enable the Profiler Conditionally for more information about using matchers to enable/disable the profiler.

ip¶

type: string

If set, the profiler will only be enabled when the current IP address matches.

path¶

type: string

If set, the profiler will only be enabled when the current path matches.

service¶

type: string

This setting contains the service id of a custom matcher.

router¶

resource¶

type: string required

The path the main routing resource (e.g. a YAML file) that contains the routes and imports the router should load.

type¶

type: string

The type of the resource to hint the loaders about the format. This isn’t needed when you use the default routers with the expected file extensions (.xml, .yml / .yaml, .php).

http_port¶

type: integer default: 80

The port for normal http requests (this is used when matching the scheme).

https_port¶

type: integer default: 443

The port for https requests (this is used when matching the scheme).

strict_requirements¶

type: mixed default: true

Determines the routing generator behaviour. When generating a route that has specific requirements, the generator can behave differently in case the used parameters do not meet these requirements.

The value can be one of:

true: Throw an exception when the requirements are not met;
false: Disable exceptions when the requirements are not met and return null instead;
null: Disable checking the requirements (thus, match the route even when the requirements don’t match).

true is recommended in the development environment, while false or null might be preferred in production.

session¶

storage_id¶

type: string default: 'session.storage.native'

The service id used for session storage. The session.storage service alias will be set to this service id. This class has to implement Symfony\Component\HttpFoundation\Session\Storage\SessionStorageInterface.

handler_id¶

type: string default: 'session.handler.native_file'

The service id used for session storage. The session.handler service alias will be set to this service id.

You can also set it to null, to default to the handler of your PHP installation.

See also

You can see an example of the usage of this in How to Use PdoSessionHandler to Store Sessions in the Database.

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_divisor¶

type: integer default: 100

See gc_probability.

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_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:

YAML

# app/config/config.yml
framework:
    session:
        save_path: ~

XML

<!-- 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>
        <framework:session save-path="null" />
    </framework:config>
</container>

PHP

// app/config/config.php
$container->loadFromExtension('framework', array(
    'session' => array(
        'save_path' => null,
    ),
));

templating¶

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

<img src="{{ asset('images/logo.png') }}" alt="Symfony!" />

PHP

<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

# app/config/config.yml
framework:
    # ...
    templating: { engines: ['twig'], assets_version: v2 }

XML

<!-- 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

// 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.

Tip

As with all settings, you can use a parameter as value for the assets_version. This makes it easier to increment the cache on each deployment.

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.

hinclude_default_template¶

type: string default: null

Sets the content shown during the loading of the fragment or when JavaScript is disabled. This can be either a template name or the content itself.

See also

See Asynchronous Content with hinclude.js for more information about hinclude.

form¶

resources¶

type: string[] default: ['FrameworkBundle:Form']

A list of all resources for form theming in PHP. This setting is not required if you’re using the Twig format for your templates, in that case refer to the form book chapter.

Assume you have custom global form themes in src/WebsiteBundle/Resources/views/Form, you can configure this like:

YAML

# app/config/config.yml
framework:
    templating:
        form:
            resources:
                - 'WebsiteBundle:Form'

XML

<!-- 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>

        <framework:templating>

            <framework:form>

                <framework:resource>WebsiteBundle:Form</framework:resource>

            </framework:form>

        </framework:templating>

    </framework:config>
</container>

PHP

// app/config/config.php
$container->loadFromExtension('framework', array(
    'templating' => array(
        'form' => array(
            'resources' => array(
                'WebsiteBundle:Form'
            ),
        ),
    ),
));

Note

The default form templates from FrameworkBundle:Form will always be included in the form resources.

See also

See Global Form Theming for more information.

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. If multiple base URLs are provided, Symfony will select one from the collection each time it generates an asset’s path:

YAML

# app/config/config.yml
framework:
    # ...
    templating:
        assets_base_urls:
            http:
                - "http://cdn.example.com/"
        # you can also pass just a string:
        # assets_base_urls:
        #     http: "//cdn.example.com/"

XML

<!-- app/config/config.xml -->
<?xml version="1.0" encoding="UTF-8" ?>
<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:framework="http://symfony.com/schema/dic/symfony">

    <framework:config>
        <!-- ... -->

        <framework:templating>
            <framework:assets-base-url>
                <framework:http>http://cdn.example.com/</framework:http>
            </framework:assets-base-url>
        </framework:templating>
    </framework:config>
</container>

PHP

// app/config/config.php
$container->loadFromExtension('framework', array(
    // ...
    'templating' => array(
        'assets_base_urls' => array(
            'http' => array(
                'http://cdn.example.com/',
            ),
        ),
        // you can also pass just a string:
        // 'assets_base_urls' => array(
        //     'http' => '//cdn.example.com/',
        // ),
    ),
));

For your convenience, you can pass a string or array of strings to assets_base_urls directly. This will automatically be organized into the http and ssl base urls (https:// and protocol-relative URLs will be added to both collections and http:// only to the http collection):

YAML

# app/config/config.yml
framework:
    # ...
    templating:
        assets_base_urls:
            - "//cdn.example.com/"
        # you can also pass just a string:
        # assets_base_urls: "//cdn.example.com/"

XML

<!-- app/config/config.xml -->
<?xml version="1.0" encoding="UTF-8" ?>
<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:framework="http://symfony.com/schema/dic/symfony">

    <framework:config>
        <!-- ... -->

        <framework:templating>
            <framework:assets-base-url>//cdn.example.com/</framework:assets-base-url>
        </framework:templating>
    </framework:config>
</container>

PHP

// app/config/config.php
$container->loadFromExtension('framework', array(

        'assets_base_urls' => array(
            '//cdn.example.com/',
        ),
        // you can also pass just a string:
        // 'assets_base_urls' => '//cdn.example.com/',
    ),
));

cache¶

type: string

The path to the cache directory for templates. When this is not set, caching is disabled.

Note

When using Twig templating, the caching is already handled by the TwigBundle and doesn’t need to be enabled for the FrameworkBundle.

engines¶

type: string[] / string required

The Templating Engine to use. This can either be a string (when only one engine is configured) or an array of engines.

At least one engine is required.

loaders¶

type: string[]

An array (or a string when configuring just one loader) of service ids for templating loaders. Templating loaders are used to find and load templates from a resource (e.g. a filesystem or database). Templating loaders must implement Symfony\Component\Templating\Loader\LoaderInterface.

packages¶

You can group assets into packages, to specify different base URLs for them:

YAML

# app/config/config.yml
framework:
    # ...
    templating:
        packages:
            avatars:
                base_urls: 'http://static_cdn.example.com/avatars'

XML

<!-- 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>

        <framework:templating>

            <framework:package
                name="avatars"
                base-url="http://static_cdn.example.com/avatars">

        </framework:templating>

    </framework:config>
</container>

PHP

// app/config/config.php
$container->loadFromExtension('framework', array(
    // ...
    'templating' => array(
        'packages' => array(
            'avatars' => array(
                'base_urls' => 'http://static_cdn.example.com/avatars',
            ),
        ),
    ),
));

Now you can use the avatars package in your templates:

Twig

<img src="{{ asset('...', 'avatars') }}">

PHP

<img src="<?php echo $view['assets']->getUrl('...', 'avatars') ?>">

Each package can configure the following options:

base_urls
version
version_format

translator¶

enabled¶

type: boolean default: false

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

fallbacks¶

type: string|array default: array('en')

New in version 2.3.25: The fallbacks option was introduced in Symfony 2.3.25. Prior to Symfony 2.3.25, it was called fallback and only allowed one fallback language defined as a string. Please note that you can still use the old fallback option if you want define only one fallback.

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

See also

For more details, see Translations.

logging¶

New in version 2.6: The 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.

validation¶

enabled¶

type: boolean default: true if form support is enabled, false otherwise

Whether or not to enable validation support.

This option will automatically be set to true when one of the child settings is configured.

cache¶

type: string

The service that is used to persist class metadata in a cache. The service has to implement the Symfony\Component\Validator\Mapping\Cache\CacheInterface.

enable_annotations¶

type: boolean default: false

If this option is enabled, validation constraints can be defined using annotations.

translation_domain¶

type: string default: validators

The translation domain that is used when translating validation constraint error messages.

strict_email¶

New in version 2.5: The strict_email option was introduced in Symfony 2.5.

type: Boolean default: false

If this option is enabled, the egulias/email-validator library will be used by the Email constraint validator. Otherwise, the validator uses a simple regular expression to validate email addresses.

api¶

New in version 2.5: The api option was introduced in Symfony 2.5.

type: string

Starting with Symfony 2.5, the Validator component introduced a new validation API. The api option is used to switch between the different implementations:

2.4: Use the vaidation API that is compatible with older Symfony versions.
2.5: Use the validation API introduced in Symfony 2.5.
2.5-bc or auto: If you omit a value or set the api option to 2.5-bc or auto, Symfony will use an API implementation that is compatible with both the legacy implementation and the 2.5 implementation. You have to use PHP 5.3.9 or higher to be able to use this implementation.

To capture these logs in the prod environment, configure a channel handler in config_prod.yml for the translation channel and set its level to debug.

annotations¶

cache¶

type: string default: 'file'

This option can be one of the following values:

file: Use the filesystem to cache annotations
none: Disable the caching of annotations
a service id: A service id referencing a Doctrine Cache implementation

file_cache_dir¶

type: string default: '%kernel.cache_dir%/annotations'

The directory to store cache files for annotations, in case annotations.cache is set to 'file'.

debug¶

type: boolean default: %kernel.debug%

Whether to enable debug mode for caching. If enabled, the cache will automatically update when the original file is changed (both with code and annotation changes). For performance reasons, it is recommended to disable debug mode in production, which will happen automatically if you use the default value.

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.
