Extend and customize Drupal functionality with contributed modules.
If a module doesn't quite do what you want it to do, if you find a bug or have a suggestion, then join forces and help the module maintainer. Or, share your own by starting a new module.
Provides one-way string transliteration (romanization) and cleans file names during upload by replacing unwanted characters.
Generally spoken, it takes Unicode text and tries to represent it in US-ASCII characters (universally displayable, unaccented characters) by attempting to transliterate the pronunciation expressed by the text in some other writing system to Roman letters.
This module is based on concepts very similar to Drupal core's update module. Modules and themes with their corresponding drupal.org projects are identified and translations are downloaded for the appropriate versions. If you use git checkouts instead of package tarballs or zip files, use Git deploy module, so projects and versions are identified properly. (For legacy CVS checkouts, the CVS deploy module will work).
Big translation files might run into your PHP timeout (#569004).
Localization client, on page translations that can be automatically submitted to the translation server
Localized Drupal, an install profile that will download translations automatically
The features module enables the capture and management of features in Drupal. A feature is a collection of Drupal entities which taken together satisfy a certain use-case.
Features provides a UI and API for taking different site building components from modules with exportables and bundling them together in a single feature module. A feature module is like any other Drupal module except that it declares its components (e.g. views, contexts, CCK fields, etc.) in its .info file so that it can be checked, updated, or reverted programmatically.
This API is meant to be used in place of the API provided by image.inc. You probably do not need to install this module unless another module are you using requires it. It provides no new features to your Drupal site. It only provides an API other modules can leverage. Currently GD2 and ImageMagick support are distributed with ImageAPI.
This module is specifically for Drupal 6 and older. This module has been integrated into Drupal 7, with the exception of ImageMagick integration, which has been moved to the ImageMagick project.
The advanced help module allows module developers to store their help outside the module system, in pure .html files. The files can be easily translated simply by copying them into the right translations directory. The entire system can appear in a popup or not as the module prefers (and by taking away access to view the popups, a site can force the popups to not exist).
The Media module provides an extensible framework for managing files and multimedia assets, regardless of whether they are hosted on your own site or a 3rd party site - it is commonly referred to as a 'file browser to the internet'.
Media is a drop-in replacement for the Drupal core upload field with a unified User Interface where editors and administrators can upload, manage, and reuse files and multimedia assets. Any files uploaded before Media was enabled will automatically take advantage of the many of the features it comes with.
Media's aim is to solve Drupal's long standing media handling problem.
What is the difference between 1.x and 2.x?
The 7.x-1.x version is the stable and recommended version for most users and production sites. It has reached feature freeze and will not be getting any new features, only bug fixes.
The Metatag module allows you to automatically provide structured metadata, aka "meta tags", about your website. In the context of search engine optimization, when people refer to meta tags they are usually referring to the meta description tag and the meta keywords tag that may help improve the rankings and display of your site in search engine results.
This module augments Views by allowing bulk operations to be executed on the displayed rows. It does so by showing a checkbox in front of each node, and adding a select box containing operations that can be applied. Drupal Core or Rules actions can be used.
ImageField provides an image upload field for CCK. ImageField is a CCK-based alternative to the legacy Image project. It boasts features such as multiple images per node, resolution restrictions, default images, and extensive Views support.
ImageField does not provide a built-in thumbnail solution, but complements the incredibly powerful thumbnail generation module ImageCache.
Checks the current URL for an alias and does a 301 redirect to it if it is not being used.
Checks the current URL for a trailing slash, removes it if present and repeats check 1 with the new request.
Checks if the current URL is the same as the site_frontpage and redirects to the frontpage if there is a match.
Checks if the Clean URLs feature is enabled and then checks the current URL is being accessed using the clean method rather than the 'unclean' method.
Checks access to the URL. If the user does not have access to the path, then no redirects are done. This helps avoid exposing private aliased node's.
Make sure the case of the URL being accessed is the same as the one set by the author/administrator. For example, if you set the alias "articles/cake-making" to node/123, then the user can access the alias with any combination of case.
Most of the above options are configurable in the settings page. In Drupal 5 you can access this after enabling the globalredirect_admin module. In Drupal 6, the settings page is bundled into the module.
FileField provides a universal file upload field for CCK. It is a robust alternative to core's Upload module and an absolute must for users uploading a large number of files. Great for managing video and audio files for podcasts on your own site.
Configurable upload paths allow you to save files into per-field or per-user directories
Per-field and per-node file size limits
Extensive API for extending field widgets and managing files
The modules list page can become quite big when dealing with a fairly large site or even just a dev site meant for testing new and various modules being considered. What this module aims to accomplish is the ability to quickly find the module you are looking for without having to rely on the browsers search feature which more times than not shows you the module name in the 'Required by' or 'Depends on' sections of the various modules or even some other location on the page like a menu item.
ImageCache allows you to setup presets for image processing. If an ImageCache derivative doesn't exist the web server's rewrite rules will pass the request to Drupal which in turn hands it off to ImageCache to dynamically generate the file.
Context allows you to manage contextual conditions and reactions for different portions of your site. You can think of each context as representing a "section" of your site. For each context, you can choose the conditions that trigger this context to be active and choose different aspects of Drupal that should react to this active context.
Think of conditions as a set of rules that are checked during page load to see what context is active. Any reactions that are associated with active contexts are then fired.
The word "title" is a bit overloaded. Every piece of content in Drupal has a title, and so does every page. The page title is the one found in the HTML head inside the <title> tag. It is also used on SERPs (Search Engine Result Pages) and can greatly enhance your websites SEO (Search Engine Optimization).
This module gives you granular control over the page title. You can specify patterns for how the title should be structured and, on content creation pages, specify the page title separately to the content's title.
Fieldgroup will, as the name implies, group fields together. All fieldable entities will have the possibility to add groups to wrap their fields together. Fieldgroup comes with default HTML wrappers like vertical tabs, horizontal tabs, accordions, fieldsets or div wrappers.
This module will display any Views date field in calendar formats, including CCK date fields, node created or updated dates, etc. Switch between year, month, and day views. Back and next navigation is provided for all views. Lots of the Calendar functionality comes from the Date module, so any time you update the Calendar module you should be sure you also update to the latest version of the Date module at the same time.
See also Date iCal, a project that contains code and features needed to either import or export dates using iCal feeds. The functionality that used to be in the Calendar iCal module has been moved into that module.
Be sure to read Debugging Information before reporting a problem. Going through those steps may resolve your problems and will help provide enough information to tell if this is a bug.
