Revision [2987]

This is an old revision of WikkaBlog made by GmBowen on 2004-12-08 23:09:07.

 

This page is copied from the TonExtraWiki where it was first developed for wakka 0.1.2 & the code published (changes to work with wikka might well be necessary). Copy to this wiki is done in recognition that some code developed in the past (such as happened at WakkaWiki) has been "lost" to general wiki users when the site was shut down & a wish for that not to happen again.

Wiki Add

(also see WikifyingTheBlog and MTPluginWiki)

This is a plugin I wrote for Wordpress. It crossposts blogpostings to the Wakka-Wiki (and easily adaptable to Wikka Wiki), and adds links to the blogpost pointing to both the normal view and edit view of the wikipage.

What do you have to do:

The code is Public Domain, feel free to use, add and adapt.

So here's the code:
<?php 
/* 
Plugin Name: Wikiadd 
Plugin URI: http://www.zylstra.org/extra/wakka.php?wakka=WikiAdd 
Description: Will crosspost wordpress posts to a wiki as well 
Version: 1.0 
Author: Ton Zijlstra 
Author URI: http://www.zylstra.org/blog 
*/ 
function wiki_link($post_ID) {
	global $wpdb, $tableposts, $tablepost2cat;
	//function called from index
	//this function creates links to the wiki on the weblogpages

	//check if the wiki category was set, which means the post has to be wiki_linked
	$wiki_cat = 15 ; // change this to the id number of your category you want to be wikified
	$query2 = "SELECT category_id FROM $tablepost2cat WHERE post_id = $post_ID AND category_id = $wiki_cat";
	$exists = $wpdb->get_var($query2);
	
	if (!empty($exists)) {
		// construct links one to see wikipage, one to edit, get post title first
		$query3 = "SELECT post_title FROM $tableposts WHERE ID = $post_ID";
		$wiki_title = $wpdb->get_var($query3);

		// in the wiki_title spaces will be replaced by capping the next letter
		$title_array = str_word_count($wiki_title,1);
		$wiki_title = "";
		$numElement = count($title_array);
		for ($pointer = 0; $pointer < $numElement; $pointer ++) {
			$wiki_title = $wiki_title . ucfirst($title_array[$pointer]);
		}
		// construct the links
		$wiki_url = "http://yourdomain.com/wakka/wakka.php?wakka="; // put the base url of your wiki here
		$wiki_see = $wiki_url . $wiki_title;
		$wiki_edit = $wiki_url . $wiki_title . "/edit";

		// print the links to the page
		echo("<a href='".$wiki_see."'>WikiGoSee</a>  |  <a href='".$wiki_edit."'>WikiWorkOnThis</a>");

	}
	return $post_ID;
}

function wiki_add($post_ID) {
	global $wpdb, $tableposts, $tablepost2cat;
	//this function adds the blogpost to the wiki-database
	
	//check if the wiki category was set, which means the post has to be wikified

		// wiki is a category so proceed
		// wikifying means 2 steps, 1 alter the original content to include links to the posting
		// and step 2 add the wiki-page
		
		// Step 1 Alter the original content to include links to the posting
		
		//get content of post from database
		$query1 = "SELECT post_content FROM $tableposts WHERE ID = $post_ID";

at**:[[".$post_link." your blogname]]";
		// now alter the wikititle to create a camelcase handle for it in the wiki
		// in the wiki_title spaces will be replaced by capping the next letter

		}
		//construct date
		$blog_date = date(Y)."-".date(m)."-".date(d)." ".date(H).":".date(i).":".date(s);
		
		// approach database
		$user="username";
		$password="password";
		$database="database";
		mysql_connect(localhost,$user,$password);
		@mysql_select_db($database) or die( "Unable to select database");
		$query5 = "INSERT INTO extra_pages VALUES
 ('','$wiki_title','$blog_date','$new_content','','','Hydrogen blog','Y','','','')";
		mysql_query($query5); 
		mysql_close();
	} // end wiki is category
 	return $post_ID;
}
# Turn on the wikifying process. 
add_action('publish_post', 'wiki_add','0'); 
add_action('wikilinker', 'wiki_link');
?>


Wishlist for improvements:

check the wiki before adding a posting to see if the title already is in use
check if the wikified title of the original blogpost is within the 50 character limit allowed by the Wakka database
