Setting up variables for use in a template (preprocess and process functions)

The main role of the preprocessor is to set up variables to be placed within the template (.tpl.php) files. Plain theme functions do not interact with preprocessors.
Notes:

• Preprocessors are also used for providing template suggestions.
• In versions 5 and below, the function _phptemplate_variables served the same purpose. It has been deprecated in 6.
• Prior to Drupal 6.7, for your theme to have its preprocessors recognized, the template associated with the hook had to exist inside the theme. When a default template exists, copy it to your theme and clear the registry (or you should really be upgrading to a later version of Drupal anyway for security reasons, at which point you don't have to worry about this).

Module - CKEditor - WYSIWYG HTML editor

This module will allow Drupal to replace textarea fields with the CKEditor - a visual HTML editor, sometimes called WYSIWYG editor. This HTML text editor brings many of the powerful WYSIWYG editing functions of known desktop editors like Word to the web. It's very fast and doesn't require any kind of installation on the client computer.

What is CKEditor?

CKEditor is the next version of FCKeditor. The editor has been rebranded and completely rewritten. It is now much faster (the code has been optimized), loads faster (the number of files has been reduced, so the browser will perform less HTTP requests) and developers friendly.

Drupal Accessibility Statement

As an inclusive community, we are committed to making sure that Drupal is an accessible tool for building websites and that Drupal helps you create websites that are themselves accessible.

This initiative started with advancements with Drupal 7 accessibility. We have committed to ensuring that all features of Drupal core conform with the Worldwide Web Consortium (W3C) guidelines: WCAG 2.0 and ATAG 2.0. Where possible we will also update the previous version of Drupal core, version 6, to enhance its accessibility.

Accessible Features in Drupal

If you rely on a screen reader or other assistive technology, you will be glad to know that we have built Drupal to encourage and support the proper use of semantic markup. For example, you should be able to use headings reliably for page-level navigation.

The accessibility team has worked to identify barriers to accessibility with Drupal and worked to resolve them. We've identified and resolved a number of issues in the core code of Drupal 7 and raised awareness within the community. We've added some additional support for Rich Internet Applications by adding some WAI-ARIA support. There have been many improvements to both the visitor and administrator sides of Drupal, especially:

• Search engine form and presentation
• Drag and Drop functionality
• Color contrast and intensity
• Adding skip navigation to core themes
• Image handling
• Form labeling
• Removing duplicate or null tags
