PmWiki is a wiki-based system for collaborative creation and maintenance of websites.
PmWiki pages look and act like normal web pages, except they have an "Edit" link that makes it easy to modify existing pages and add new pages into the website, using basic editing rules. You do not need to know or use any HTML or CSS. Page editing can be left open to the public or restricted to small groups of authors.
Key PmWiki Features
Custom look-and-feel: A site administrator can quickly change the appearance and functions of a PmWiki site by using different
skins and HTML templates. If you can't find an appropriate skin
already made, you can easily modify one or create your own.
Access control: PmWiki password protection can be applied to an entire site, to groups of pages, or to individual pages. Password protection controls who can read pages, edit pages, and upload attachments. PmWiki's access control system is completely self-contained, but it can also work in conjunction with existing password databases, such as
.htaccess, LDAP servers, and MySQL databases.
Customization and plugin architecture: One principle of the
PmWikiPhilosophy is to only include essential features in the core engine, but make it easy for administrators to customize and add new markup. Hundreds of features are already available by using extensions (called "recipes") that are available from the PmWiki
Cookbook.
PmWiki is written in PHP and distributed under the General Public License. It is designed to be simple to install, customize, and maintain for a variety of applications. This site is running pmwiki-2.2.11.

PmWiki has support for handling the case where multiple authors attempt to edit the same page nearly simultaneously. Here's the basic scenario for systems where simultaneous edits are not handled:
- Alice starts to edit a page.
- Before Alice saves her edits, Bob requests an edit of the same page, and receives the page text prior to Alice's edits.
- Bob finishes with his edits and hits "save".
- Alice finishes editing her page, hits "save", and since she was working from a version of the page from before Bob had made his changes, she wipes out Bob's edits in the process.
PmWiki's simultaneous edit feature detects when this occurs, and instead of saving Alice's edits PmWiki presents Alice with a message that someone else changed the page while she was editing it. Furthermore, Bob's changes are merged into Alice's copy of the page, with any conflicts highlighted by <<<<<<< and >>>>>>>. Alice can then fix things as appropriate and save the updated page, or, if Alice is lazy, she can just hit "save" a second time and leave it to someone else to fix.
The simultaneous edits feature is also invoked whenever someone requests a page preview; thus if a page changes while previewing a page the author gets notification and can see the merged results.
How can I test/experiment with this feature?
- Open up two browser windows and select the same page to be edited in each window (e.g., try WikiSandbox?action=edit).
- In one browser window, make some changes to the page and then save those changes.
- In the second browser window, make some different changes to the same page and hit "save". Since the page changed after the edit form was loaded into the second window, there's a potential edit conflict and you'll receive the "edit conflict message".
- You can make any adjustments in the second window, and press "Save" again to save the changes.
Notice
Some server environments such as Windows and PHP running in safe_mode are unable to use the simultaneous edits capability distributed with PmWiki. See Cookbook:SimultaneousEdits for a solution for these environments.
