single: Configuration reference; 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.
- secret
- http_method_override
- ide
- test
- trusted_proxies
- form
- enabled
- csrf_protection
- enabled
- field_name
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.
.. versionadded:: 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
:method:`Request::enableHttpMethodParameterOverride <Symfony\\Component\\HttpFoundation\\Request::enableHttpMethodParameterOverride>`
gets called automatically. It becomes the service container parameter named
kernel.http_method_override. For more information, see
:doc:`/cookbook/routing/method_parameters`.
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.
If you use TextMate or Mac Vim, you can simply use one of the following built-in values:
textmatemacvim
You can also specify a custom file link string. If you do this, all percentage
signs (%) must be doubled to escape that character. For example, the
full TextMate string would look like this:
framework:
ide: "txmt://open?url=file://%%f&line=%%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
php.ini value to the file link string. If this configuration value is set, then
the ide option does not need to be specified.
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 :doc:`/book/testing`.
type: array
Configures the IP addresses that should be trusted as proxies. For more details, see :doc:`/components/http_foundation/trusting_proxies`.
.. versionadded:: 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``).
.. configuration-block::
.. code-block:: yaml
framework:
trusted_proxies: [192.0.0.1, 10.0.0.0/8]
.. code-block:: xml
<framework:config trusted-proxies="192.0.0.1, 10.0.0.0/8">
<!-- ... -->
</framework>
.. code-block:: php
$container->loadFromExtension('framework', array(
'trusted_proxies' => array('192.0.0.1', '10.0.0.0/8'),
));
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.
type: integer default: null
This determines the lifetime of the session - in seconds. It will use null by
default, which means session.cookie_lifetime value from php.ini will be used.
Setting this value to 0 means the cookie is valid for the length of the browser
session.
type: string default: /
This determines the path to set in the session cookie. By default it will use /.
type: string default: ''
This determines the domain to set in the session cookie. By default it's blank, meaning the host name of the server which generated the cookie according to the cookie specification.
type: Boolean default: false
This determines whether cookies should only be sent over secure connections.
type: Boolean default: false
This determines whether cookies should only be accessible through the HTTP protocol. This means that the cookie won't be accessible by scripting languages, such as JavaScript. This setting can effectively help to reduce identity theft through XSS attacks.
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.
type: integer default: 100
See gc_probability.
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.
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 :doc:`/cookbook/session/sessions_directory`.
You can also set this value to the save_path of your php.ini by setting
the value to null:
.. configuration-block::
.. code-block:: yaml
# app/config/config.yml
framework:
session:
save_path: null
.. code-block:: xml
<!-- app/config/config.xml -->
<framework:config>
<framework:session save-path="null" />
</framework:config>
.. code-block:: php
// app/config/config.php
$container->loadFromExtension('framework', array(
'session' => array(
'save_path' => null,
),
));
type: boolean default: false
Whether to enable the serializer service or not in the service container.
For more details, see :doc:`/cookbook/serializer`.
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, Symfony2
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.
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:
.. configuration-block::
.. code-block:: html+jinja
<img src="{{ asset('images/logo.png') }}" alt="Symfony!" />
.. code-block:: 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:
.. configuration-block::
.. code-block:: yaml
# app/config/config.yml
framework:
# ...
templating: { engines: ['twig'], assets_version: v2 }
.. code-block:: xml
<!-- app/config/config.xml -->
<framework:templating assets-version="v2">
<framework:engine id="twig" />
</framework:templating>
.. code-block:: php
// app/config/config.php
$container->loadFromExtension('framework', array(
...,
'templating' => array(
'engines' => array('twig'),
'assets_version' => 'v2',
),
));
Now, the same asset will be rendered as /images/logo.png?v2 If you use
this feature, you must manually increment the assets_version value
before each deployment so that the query parameters change.
You can also control how the query string works via the assets_version_format option.
type: string default: %%s?%%s
This specifies a :phpfunction:`sprintf` pattern that will be used with the assets_version
option to construct an asset's path. By default, the pattern adds the asset's
version as a query string. For example, if assets_version_format is set to
%%s?version=%%s and assets_version is set to 5, the asset's path
would be /images/logo.png?version=5.
Note
All percentage signs (%) in the format string must be doubled to escape
the character. Without escaping, values might inadvertently be interpreted
as :ref:`book-service-container-parameters`.
Tip
Some CDN's do not support cache-busting via query strings, so injecting the
version into the actual file path is necessary. Thankfully, assets_version_format
is not limited to producing versioned query strings.
The pattern receives the asset's original path and version as its first and
second parameters, respectively. Since the asset's path is one parameter, you
cannot modify it in-place (e.g. /images/logo-v5.png); however, you can
prefix the asset's path using a pattern of version-%%2$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 forgo any URL rewriting. The latter option is useful if you would like older asset versions to remain accessible at their original URL.
.. versionadded:: 2.2
The ``enabled`` option was introduced in Symfony 2.2. Previously, the profiler
could only be disabled by omitting the ``framework.profiler`` configuration
entirely.
default: true in the dev and test environments
The profiler can be disabled by setting this key to false.
.. versionadded:: 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.
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:
$profiler->enable();
