Wiki source for WikkaBlog2

====WikkaBlog====
{{lastedit show="3"}}
Blogs (or web-logs) are currently immensely popular and there are countless web programs to run both individual and collections of blogs. This action is designed to provide blog-functionality (pagination and commenting) to wikka users...essentially allowing wikka to be used as a blog farm if so desired. Use requires two mysql tables, an action script, and an included class (to drive the pagination). Blog submissions have limited wikka formatting (listed under the submit window). This action complements the free-form editing in wikka and the structured thread discussions in WikkaForum.

The two mysql tables are structured as follows.....(replace "wakka_" with whatever your database prefix is)
%%(sql)
CREATE TABLE `wakka_blogcomments` (
`id` int(11) NOT NULL auto_increment,
`blogid` tinyint(4) NOT NULL default '0',
`time` datetime default NULL,
`commentowner` text NOT NULL,
`comment` text NOT NULL,
UNIQUE KEY `id` (`id`)
) TYPE=MyISAM;

CREATE TABLE `wakka_blogs` (
`id` int(11) NOT NULL auto_increment,
`pagename` text NOT NULL,
`time` datetime default NULL,
`name` text NOT NULL,
`blogname` text,
`ownername` text,
`topic` text NOT NULL,
`message` text NOT NULL,
UNIQUE KEY `id` (`id`)
) TYPE=MyISAM;

@description: this file requires you are running wikka wiki
and that you've inserted 2 tables into the wikka MYSQL database.
AND **REQUIRES** a pagination class file (page.inc.php) in the wikka root directory "scripts"
// config vars //
numrec= : how many pages are going to be displayed in the list. (optional, default=5)
share= : list of users who can contribute to blog (optional, default = owner)
caption= : Header text for blog (optional, default is null)
NOTE: Comments feature use ACLS permissions to determine who can contribute
@usage: insert {{blog}} anywhere in a wikka wiki page.

The blog.php action on this page can use a "bad word function" that should be placed **in** the wikka.php file in the wiki root directory. The following code needs to be placed in the wikka.php file (just after the microtime function which starts "function getmicrotime" and ends with a "}". This code is placed immediately after the "}".

%%(php)

function BadWordFunc($RemoveBadWordText) {

The main entry page looks like this....

and the comment page, which shows one blog entry box and then the listed comments, looks like.....
http://gmbtst.msvu.ca/wikitest/wikkablog2.jpg

~& Changed wakka.php to wikka.php in instructions for badword filter - JoelCant
~& (moved from WikkaBugs) This is about WikkaBlog2. --- I find that noone is allowed to post blog comments (i.e. not the wikka page std comments). All ACLs are '*'; I even blanked all, or have the page owned by nobody, and still no rights; I suppose ""HasAccess""('comment') fails. (see [[http://cativan.com/VisitingIdeas this page]]) -- CatIvan
~& Is this a good solution? in blog.pgp, line 112 "if ( /*$user = $this->""GetUser""() &&*/ $this->""HasAccess""('comment'))" -- the 1st test condition fails for anonymous users; it seems to me the 2nd statement (ACL based) is sufficient. -- CatIvan
