How to create a wiki in Drupal 6

Due to a requirement for a work related project, I needed to structure a wiki to provide a 'how to' guide for a site.  Having already built one in Drupal 6 several months ago (, I decided to use Drupal 7, but quickly discovered that most of the modules aren't updated for Drupal 7 and rolled everything back to 6.  This is the document process for this version.  The wiki that I've created is at

Modules needed:

  • Drupal 6
  • WikiTools
  • Flexifilter  (Drupal 7 build is still in development at this was written)
  • Diff: (Optional) Allows you to see/compare any changes or updates.
  • TOC: (Optional) Creates a nice table of contents format.
  • Admin Menu:  (Optional) It makes life easier.
  • Talk: (Optional) It allows for a dialogue on the page.

Once you've got those loaded into your server, you can start to install and configure your Wiki site.

1. Install Drupal 6 as you normally would.

2. Install and activate the WikiTools, Flexifilter, Diff, TOC, Admin Menu, and Talk modules.

3. Create a new content type named 'Wiki'.  If you'd like, give it this description:

A <em>wiki page</em> is a page of content, organized into a collection of related entries collectively known as a <em>wiki</em>. A <em>wiki page</em> automatically displays links to adjacent pages, providing a simple navigation system for organizing and reviewing structured content.

Options to select when creating the content type:

  • Add the table at the top
  • Remove the table from the teaser

3. Configure the WikiTools module at [YOURSITE.COM]/admin/settings/wikitools.

  • Pay special attention to the node types, by default it's set to articles.
  • Options:  I'm using node creation, node search, automatic redirect, unique titles, and treat underscores as spaces.
  • 404 Type - Link to Creation:  If the page that you're linking to doesn't exist, provide a link to create it.

4. Create the new filter (import or manual way).  This probably won't import for some reason, but it's worth a try.  Navigate to [YOURSITE.COM]/admin/build/flexifilters and click 'Import a New FlexiFilter'.

5a. Import this code:

5b. The manual way (partially lifted from here):

  1. Go to the flexifilter administration area by clicking Administer -> Site Building -> Flexifilters, and click 'Add new flexifilter'.
  2. Set the label to 'Wiki'.
  3. Set the description to 'Add a link to another page [[link|Title]], ====H4====, ===H3===, ==H2==, '''strong''', ''italics'''.
  4. Prepend with </nowiki>.
  5. Append with <nowiki>
  6. Do a chunk grab on </nowiki> and <nowiki>.
  7. Add several pattern-based text replace components:
  8. Replace ''' (three single dashes) with alternating <strong> and </strong>.
  9. Replace '' (two single dashes) with alternating <em> and </em>.
  10. Replace ==== (four equals signs) with alternating <h4> and </h4>
  11. Replace === (three equals signs) with alternating <h3> and </h3>
  12. Replace == (two equals signs) with alternating <h2> and </h2>
  13. Create a chunk grabber on [[ and ]].
  14. Add an IF component within the chunk grabber.
  15. Add the condition "text contains" with the parameter |.
  16. As subcomponents of this IF statement, prepend with <a href="/drupalwikipath/
  17. String replace | with ">.
  18. Append </a>.

6. Enable your new Flexifilte if it's not already enabled.

7. Navigate to [YOURSITE.COM//admin/config/content/formats] and allow Wiki format for your desired input format (text input is a good place to start).

8. Navigate to your wiki content type [YOURSITE.COM//admin/structure/types/manage/article] (default is 'article') and confirm that Diff is enabled .

9.  Create a new wiki page, and you'll see the options in the filters.
