[Phpwiki-talk] Page Trail plugin (comments)

[Paul P. <wa...@gl...>]

One of the features which I found to be missing from phpWiki is the ability 
to have a page trail of the last pages which you clicked on. I worked for a 
while trying to understand the phpWiki plugins and I think I have it. If 
anyone would like to try it, feel free, and let me know if you have 
suggestions, comments, or questions. The basis for this is the 
HelloWorld.php plugin...

===Start of PageTrail.php===

<?php // -*-php-*-
rcs_id('$Id: PageTrail.php,v 1.1 2002/09/24 21:56:28 ppearson Exp $');
/**
  * A simple PageTrail WikiPlugin.
  *
  * Usage:
  * <?plugin PageTrail?>
  * <?plugin PageTrail numberlinks=5?>
  */

// Constants are defined before the class.
if (!defined('THE_END'))
     define('THE_END', "!");

class WikiPlugin_PageTrail
extends WikiPlugin
{
     // Four required functions in a WikiPlugin.

     function getName () {
         return _("PageTrail");
     }

     function getDescription () {
         return _("PageTrail Plugin");

     }
     // Establish default values for each of this plugin's arguments.
     function getDefaultArguments() {
         return array('numberlinks' => "5");
     }

     function run($dbi, $argstr, $request) {
	global $Theme;
         extract($this->getArgs($argstr, $request));

	if ($numberlinks>5 || $numberlinks<0) { $numberlinks=5;}

         // Get name of the current page we are on
	$thispage = $GLOBALS['request']->args['pagename'];
         $Page=array();
         // Shift down the page names and store them back to cookies
         for ($count=$numberlinks; $count>0; $count--) {
		$thisvalue="PageTrail".$count;
                 $thiscookie = @$_COOKIE["$thisvalue"];
                 if ($thiscookie!="") {
                         $Page[$count+1]=$thiscookie;
                 } else {
                         $Page[$count+1]="";
                 }
         }
         $Page[1]=$thispage;
         // Now lets cycle through them saving them with setcookie
         $html = " ";
         for ($count=$numberlinks; $count>0; $count--) {
                 if ($Page[$count]!="") {
                         $Name="PageTrail" . $count;
			$Value = $Page[$count];
			setcookie ($Name, $Value, 0, '/');
		}
	}
	$html = HTML::tt(fmt('%s ==> %s ==> %s ==> %s ==> %s', WikiLink($Page[5], 
'auto'), WikiLink($Page[4], 'auto'), WikiLink($Page[3], 'auto'), 
WikiLink($Page[2], 'auto'), WikiLink($Page[1], 'auto')),THE_END);
	return $html;
     }
};
