Silverstripe CMS

Silverstripe CMS is a free and open source content management system (CMS) and framework for creating and maintaining websites and web applications. It provides an out of the box web-based administration panel that enables users to make modifications to parts of the website, which includes a WYSIWYG website editor. The core of the software is Silverstripe Framework, a PHP Web application framework.

Software design

Silverstripe CMS separates the roles of:

  • content authors (who get a rich (AJAX) web-based user interface that omits technical jargon); and
  • website designers/developers (who write code: HTML, CSS, JavaScript, and PHP)

This contrasts with CMS products which allow technical website development tasks to be performed within a GUI, and also contrasts with programming frameworks which offer no out-of-the-box content authoring application. The Silverstripe CMS approach allegedly removes complexity for content authors, and offers more flexibility to developers.[3]

The core of Silverstripe CMS is named Silverstripe Framework (formerly referred to as "Sapphire").[4] As with the rest of the platform, it is written in PHP (5.3), and takes advantage of its object-oriented design capabilities such as name-spacing. The Silverstripe Framework provides website developers a framework to build and extend websites based on modern programming techniques including the model-view-controller pattern and object-relational mapper.

Silverstripe CMS generates markup using a custom template-language based on W3C HTML5 that offers simple placeholders and conditional logic. Silverstripe CMS is extensible through modules, widgets, themes and code customization.

Modules, widgets, and themes

Modules can be used to extend the core functionality of Silverstripe CMS. Some existing modules include: Blog, Advanced Workflow Management, eCommerce, Forum, and LDAP/OpenID authentication. Modules are available from the Silverstripe CMS modules repository, which as of October 2022, lists over 3000 modules.

Silverstripe CMS Widgets are small pieces of functionality that can be drag-and-dropped into Silverstripe CMS modules (notably the blog module). Examples of widgets include: tag clouds, Flickr photos, or word of the day. Widgets are a relatively less-used aspect of the platform. As of August 2012, there are 96 widgets.

The Silverstripe CMS themes directory provides a number of community-contributed, freely available themes (114 as of October 2022).

Modules, widgets, and themes are all available as free downloads under the BSD license, and the majority of them are community contributed.
