Questions answered by this recipe

How can I integrate SMF Simple Machines Forum with PmWiki?
How can I create a single sign-on/log-on for both Pmwiki and SMF?

Description

This recipe integrates SMF with PmWiki and uses SMF's user management for PmWiki's AuthUser authentication

Installation

1. Install SMF Simple Machines Forum in its own directory. Preferably into directory smf/ in your site root (the following script is using this, but it could be changed).
2. Edit the SMF Settings.php file manually and add to section 'Forum Info' below $boardurl = ...
   $scripturl = $boardurl . '/index.php'; //URL of SMF board script
3. Make sure SMF runs.
4. Download and copy auth-smf.phpΔ to your cookbook directory.
   • For PHP 5.5 or newer please get auth-smf-php72.phpΔ instead and rename it to auth-smf.php.
5. Add to config.php, preferably early on (adjust path to SMF root directory as needed):
   $SMFDir = "../smf"; //path to SMF root directory
   include_once("$FarmD/cookbook/auth-smf.php");
6. Add default passwords for @admin and @editor groups, as these are authenticated. Add to config.php after the above inclusion of cookbook/auth-smf.php (authuser.php is included from within auth-smf.php):
   $DefaultPasswords['admin'] = '@admin';
   $DefaultPasswords['edit'] = '@editor';
7. Test everything. Try some page variables in a wiki page to see what PmWiki allocates by the SMF login process, try editing under various authentications:
   *AuthId: {$AuthId}
   *Author: {$Author}
   *{$UserName}: {$UserEmail}

Usage

The script auth-smf.php integrates user authentication of PmWiki with SMF.
Logging into SMF logs you also into Pmwiki, and vice versa.
The authentication is used in PmWiki, using it's AuthUser script (included via auth-smf.php).
Logging out of SMF also logs out of PmWiki.
New users get added as new forum members via the SMF registration process. No separate authuser list needs to be kept by PmWiki.
PmWiki ?action=login and ?action=logout will also log into or log out off SMF.
A login form specified on a page Site.SMFAuthForm will be used if present (see example below).

• A SMF Administrator (ID_GROUP = 1) will be assigned to PmWiki @admin auth group.
• A SMF Global Moderator (ID_GROUP = 2) will be assigned to PmWiki @editor auth group.

You can set your Pmwiki default passwords in config.php accordingly:

Normal forum members will not have wiki edit permissions in this setup! If they should have edit permissions, in auth-smf.php the following line

needs to be changed to

Example for Site.SMFAuthForm

'''$[User Name & Password required]'''
(:messages:)
(:if enabled InvalidLogin:)* $[Name/password not recognized]
(:if:)
(:input smf_auth_form:)
(:input hidden cookielength -1:)
||width=12em
||$[User Name]: ||(:input text id=user name=user:) ||
||$[Password]: ||(:input password id=passwrd name=passwrd:) ||
|| ||(:input submit value='Login':) ||
(:input end:)

SMF includes

The SMF file SSI.php provides a number of 'content includes', which can be used by special markup inside Pmwiki pages to provide hooks into SMF, like a login form, welcome message, logout link, forum search form, menu bar, tabulatd recent posts, recent topics, top topics views etc.

Use the generic markup (:smf-SSIfunction:), replace SSIfunction with the function name of your choosing, but without the ssi_ prefix. You can also add arguments if the function accepts them, like (:smf-recentPosts 10:), which will display a table with links to the latest 10 forum posts in the wiki page. The directives listing links to posts and topics etc accept a number as argument, the login and logout directives accept a full url for redirection.

Here are some examples of possible smf markup directives:

Full list of smf markups:

(:smf-shutdown:)
(:smf-welcome:)
(:smf-menubar:)
(:smf-logout:)
(:smf-recentPosts:)
(:smf-recentTopics:)
(:smf-topPoster:)
(:smf-topBoards:)
(:smf-topTopics:)
(:smf-topTopicsReplies:)

(:smf-topTopicsViews:)
(:smf-latestMember:)
(:smf-boardStats:)
(:smf-whosOnline:)
(:smf-logOnline:)
(:smf-login:)
(:smf-topPoll:)
(:smf-recentPoll:)
(:smf-showPoll:)
(:smf-pollVote:)

(:smf-quickSearch:)
(:smf-news:)
(:smf-todaysBirthdays:)
(:smf-todaysHolidays:)
(:smf-todaysEvents:)
(:smf-todaysCalendar:)
(:smf-boardNews:)
(:smf-recentEvents:)
(:smf-checkPassword:)

Additional page variables

{$AuthId}

displays the authenticated user/forum member in a wiki page (defined in Pmwiki).

{$UserName}

displays the user/member's real name as used in the forum, which can be distinct from the user's login id (AuthId, or memberName in SMF).

{$UserEmail}

displays the user/member's email address. I thought this may come handy for creating special mailing lists using FoxNotify etc.

Other user settings could be added as page variables, by creating similar definitions as I did for above in auth-smf.php. If you like to explore the possibilities, uncomment the line with echo .... $user_settings.. to see what user settings are available in SMF.

Notes

Release Notes

If the recipe has multiple releases, then release notes can be placed here. Note that it's often easier for people to work with "release dates" instead of "version numbers".
