Extension:PageAttachment

What can this extension do?
This extension extends MediaWiki to allow adding files to a page as attachments.

By default, attachments are only allowed to be added to pages in the "Main" namespace. Through configuration changes, attachments can be allowed to be attached to any other pages under other namespaces, for example, "User Talk" pages.

Security
Every precaution has been taken to make this extension secure by following guidelines outlined in MediaWiki's security manual for developers.

Please see the detailed installation instructions on the following link:

PageAttachment Installation

Configuration
For complete & detail configuration options, see the following link:

Complete & Detail Configuration Options


 * NOTE: The configuration options detailed in the following would be removed in the future.
 * Since the configuration options are huge and hard to maintain on a single page.

It is recommended to use the site specific configuration file to override the defaults and specify site specific settings. Default configuration file is: config/DefaultConfigurations.php Site specific configuration file is: config/SiteSpecificConfigurations.php

Allowed Namespaces
Attachments are allowed only on pages under configured namespaces.

By default, only "Main" namespace is enabled:

MediaWiki User Rights
For upload & attachment activity, check is made to ensure the following:
 * User is not blocked
 * Wiki is not in readonly mode

PageAttachment User Rights

 * View attachments
 * Upload & attach a file
 * Browse/Search for existing (uploaded) files and attach
 * Remove attachments
 * Download attachments
 * View history
 * View audit log (if audit logging is enabled)

NOTE: View rights must be enabled for all other rights to work

 * Only at the activity level (e.g. upload & attach a file)
 * When login is required, rights can be applied to each activity
 * At a group level
 * At a user specific level

NOTE: The groups/users must be valid MediaWiki groups/users.

Audit Log
Audit logging by default is turned off. To enable audit logging, set the following:

Cache

 * Server side cache
 * PageAttachment extension uses cache to store page attachment list, attachment data, and article names.
 * MediaWiki's Cache
 * By default, MediaWiki cache is used and recommended.
 * Recommeded for Production use.
 * To use MediaWiki's cache, no configuration change is required.
 * Please consult: MediaWiki Cache Setup
 * '''PageAttachment's Internal Cache
 * Alternatively, you can use one of the two internal cache implementations.
 * * SQLite3 Cache
 * * Database Cache
 * Use internal cache implementations for development & testing purposes only.
 * To use SQLite3 internal cache, set the following in the site-specific configuration file:


 * To use Database cache, set the following in the site-specific configuration file:


 * Browser cache
 * Ajax is used to load the page attachment list.
 * By default Ajax data caching in user's web browser is disabled. The reason for this that Ajax caching will sometime cause inconsistent data display based on when an attachment was added/update/removed and after user's login/logout.
 * If you want to enable Ajax caching, set the following in the site-specific configuration file:


 * N = Number of seconds to cache Ajax data in the user's browser.
