This document describes the changes made in symfony 1.3/1.4 and what need to be done to upgrade your symfony 1.2 projects.
If you want more detailed information on what has been changed/added in symfony 1.3/1.4, you can read the What's new? tutorial.
symfony 1.3/1.4 is compatible with PHP 5.2.4 or later. It might also work with PHP 5.2.0 to 5.2.3 but there is no guarantee.
There is no upgrade task in symfony 1.4 as this version is the same as symfony 1.3 (minus all the deprecated features). To upgrade to 1.4, you must first upgrade to 1.3, and then switch to the 1.4 release.
Before upgrading to 1.4, you can also validate that your project does not use
any deprecated class/method/function/setting/... by running the
$ php symfony project:validate
The task lists all the files you need to change before switching to symfony 1.4.
Be aware that the task is a glorified regular expression and might gives you many false positives. Also, it cannot detect everything, so it is just a tool that helps you identifying possible problems, not a magic tool. You still need to read the DEPRECATED tutorial carefully.
sfProtoculousPlugin have been removed from 1.4. If
you are explicitly disabling them in your project's configuration class files,
config/ProjectConfiguration.class.php, you must remove all mention of
them from those files.
To upgrade a project:
Check that all plugins used by your project are compatible with symfony 1.3
If you don't use a SCM tool, please make a backup of your project.
Upgrade symfony to 1.3
Upgrade the plugins to their 1.3 version
project:upgrade1.3task from your project directory to perform an automatic upgrade:
$ php symfony project:upgrade1.3
This task can be launched several times without any side effect. Each time you upgrade to a new symfony 1.3 beta / RC or the final symfony 1.3, you have to launch this task.
You need to rebuild your models and forms due to some changes described below:
# Doctrine $ php symfony doctrine:build --all-classes # Propel $ php symfony propel:build --all-classes
Clear the cache:
$ php symfony cache:clear
The remaining sections explain the main changes made in symfony 1.3 that need some kind of upgrade (automatic or not).
During the symfony 1.3 development, we have deprecated and removed some settings, classes, methods, functions, and tasks. Please refer to Deprecations in 1.3 for more information.
As of symfony 1.3, the files under the
lib/vendor/ directory are not
autoloaded anymore by default. If you want to autoload some
sub-directories, add a new entry in the application
autoload: vendor_some_lib: path: %SF_LIB_DIR%/vendor/some_lib_dir recursive: on
The automatic autoloading of the
lib/vendor/ directory was problematic for
If you put a library under the
lib/vendor/directory that already has an autoload mechanism, symfony will re-parse the files and add a bunch of unneeded information in the cache (see #5893 - http://trac.symfony-project.org/ticket/5893).
If your symfony directory is not exactly named
lib/vendor/symfony/, the project autoloader will re-parse the whole symfony directory and some problems might occur (see #6064 - http://trac.symfony-project.org/ticket/6064).
Autoloading in symfony 1.3 is now case-insensitive.
methods do not return the routes as an array as they did in previous versions.
lazy_routes_deserialize option has been removed as it is not needed
As of symfony 1.3, the cache for the routing is disabled, as this is the best
option for most projects as far as performance are concerned. So, if you have
not customized the routing cache, it will be automatically disabled for all
your applications. If after upgrading to 1.3, your project is slower, you
might want to add some routing cache to see if it helps. Here is the symfony
1.2 default configuration you can add back to your

helpers in your layout:
It has been removed for several reasons:
We already have a better, simple, and more flexible solution (the
Even if the filter can be easily disabled, it is not an easy task as you must first know about its existence and its "behind the scene" magic work
Using the helpers provides more fined-grained control over when and where the assets are included in the layout (the stylesheets in the
bodytag for instance)
It is always better to be explicit, rather than implicit (no magic and no WTF effect; see the user mailing-list for a lot of complaints on this issue)
It provides a small speed improvement
How to upgrade?
commonfilter need to be removed from all
filters.ymlconfiguration files (this is automatically done by the
You need to add
project:upgrade1.3task for HTML layouts contained in the
templates/directories of your applications - they must have a
sfCommonFilter class is still bundled with symfony 1.3, and so you can
still use it in your
filters.yml if you need to.
The following task classes have been renamed:
|symfony 1.2||symfony 1.3|
The signature for the
*:data-load tasks has changed. Specific directories or
files must now be provided as arguments. The
--dir option has been removed.
$ php symfony doctrine:data-load data/fixtures/dev
sfFormatter::format() third argument has been removed.
esc_js_no_entities(), refered to by
ESC_JS_NO_ENTITIES was updated to
correctly handle non-ANSI characters. Before this change all but characters with
177 were escaped. Now it will only escape backslashes
" and linebreaks

you previously relied on this broken behaviour.
The externals to Doctrine have been updated to use the latest and greatest Doctrine 1.2 version. You can read about what is new in Doctrine 1.2 here.
The admin generator batch delete was changed to fetch the records and issue the
delete() method to each one individually instead of issuing a single DQL query
to delete them all. The reason is so that events for deleting each individual
record are invoked.
You can override the model included in a plugins YAML schema simply by defining
that same model in your local schema. For example, to add an "email" column
sfGuardUser model, add the following to
sfGuardUser: columns: email: type: string(255)
The package option is a feature of Doctrine and is used for the schemas of symfony plugins. This does not mean the package feature can be used independently to package your models. It must be used directly and only with symfony plugins.
The Doctrine integration logs queries run using
than by accessing the logger object directly. Additionally, the subject of
these events is either the connection or statement that is running the query.
Logging is done by the new
sfDoctrineConnectionProfiler class, which can be
accessed via a
If you use the

ProjectConfiguration class, be warned that we now sort the plugins by
name to ensure consistency across different platforms.
sfWidgetFormInput class is now abstract. Text input fields are now
created with the
sfWidgetFormInputText class. This change was made to ease
introspection of form classes.
Symfony 1.3 has a new mailer factory. When creating a new application, the
factories.yml has sensible defaults for the
But if you upgrade an existing project, you might want to update your
factories.yml with the following configuration for these environments:
mailer: param: delivery_strategy: none
With the previous configuration, emails won't be sent. Of course, they will
still be logged, and the
mailer tester will still work in your functional
If you'd rather want to receive all emails to a single address, you can use
single_address delivery strategy (in the
dev environment for
dev: mailer: param: delivery_strategy: single_address delivery_address: email@example.com
If your project uses an older version of Swiftmailer, you must remove it.
sfYAML is now more compatible with the 1.2 spec. Here are the changes you might need to do in your configuration files:
Booleans can now only be represented with the
falsestrings. If you used the alternative strings in the following list, you must replace them with either
project:upgrade task tells you where you use old syntax but does not fix
them (to avoid loosing comments for instance). You must fix them by hand.
If you don't want to check all your YAML files, you can force the YAML parser
to use the 1.1 YAML specification by using the
The custom Propel builder classes used in previous versions of symfony have
been replaced with new Propel 1.4 behavior classes. To take advantage of this
enhancement your project's
propel.ini file must be updated.
Remove the old builder classes:
; builder settings propel.builder.peer.class = plugins.sfPropelPlugin.lib.builder.SfPeerBuilder propel.builder.object.class = plugins.sfPropelPlugin.lib.builder.SfObjectBuilder propel.builder.objectstub.class = plugins.sfPropelPlugin.lib.builder.SfExtensionObjectBuilder propel.builder.peerstub.class = plugins.sfPropelPlugin.lib.builder.SfExtensionPeerBuilder propel.builder.objectmultiextend.class = plugins.sfPropelPlugin.lib.builder.SfMultiExtendObjectBuilder propel.builder.mapbuilder.class = plugins.sfPropelPlugin.lib.builder.SfMapBuilderBuilder
And add the new behavior classes:
; behaviors propel.behavior.default = symfony,symfony_i18n propel.behavior.symfony.class = plugins.sfPropelPlugin.lib.behavior.SfPropelBehaviorSymfony propel.behavior.symfony_i18n.class = plugins.sfPropelPlugin.lib.behavior.SfPropelBehaviorI18n propel.behavior.symfony_i18n_translation.class = plugins.sfPropelPlugin.lib.behavior.SfPropelBehaviorI18nTranslation propel.behavior.symfony_behaviors.class = plugins.sfPropelPlugin.lib.behavior.SfPropelBehaviorSymfonyBehaviors propel.behavior.symfony_timestampable.class = plugins.sfPropelPlugin.lib.behavior.SfPropelBehaviorTimestampable

The unit test bootstrap file,
test/bootstrap/unit.php, has been enhanced to
better handle autoloading of project class files. The following lines must be
added to this script:
$autoload = sfSimpleAutoload::getInstance(sfConfig::get('sf_cache_dir').'/project_autoload.cache'); $autoload->loadConfiguration(sfFinder::type('file')->name('autoload.yml')->in(array( sfConfig::get('sf_symfony_lib_dir').'/config/config', sfConfig::get('sf_config_dir'), ))); $autoload->register();
