I'm looking for CMS built in symfony framework. Any examples?
Take a look at http://www.steercms-project.org/ and/or http://diem-project.org/
Maybe Sympal could interest you : it's writtent by jwage, who is also the author or Doctrine, the ORM used by default by symfony :
Sympal is a Content Management System built on top of the popular PHP MVC framework, Symfony.
It's architecture is simple and utilizes the native Symfony plugin architecture to make easy to use plug n' play CMS functionality.
It's still work in progress, though, I think...
Check also http://www.symfony-project.org/plugins/sfSimpleCMSPlugin
And http://www.apostrophenow.com/
That, as is explained here:
Apostrophe is an open source CMS suite made up of several Symfony plugins, including pkContextCMSPlugin. The plugins are all under the MIT license.
Apostrophe starts out as a traditional CMS, dealing with pages and in- context editing of slots of content on pages, but also adds support for 'engines', entire Symfony modules grafted into the CMS tree wherever the admin wishes to put them. Engines provide the sort of flexibility people normally associate with Drupal.
You should consider using Diem.
Based on symfony 1.4, it also brings parts of Symfony 2.0 such as the Dependency Injection Container. It makes the whole thing very flexible and extensible.
Diem is already used to build dozens of complex websites, the project is very active and the community is amazing.
