=====Redirecting Pages=====
before we can MovePages we'll need a redirector to keep the links to the old wikiword intact. this facility is useful for other reasons too. it can serve synonyms, acronyms and different transcriptions of foreign names. we'll hook in at the function run() after we've got all information we need (the page itself and it's acls):

run():

%%(php)<?
	// ...
	if ($this->method == "show" && $_REQUEST["redirect"] != "no") $this->GetTargetPage();
	$this->ReadInterWikiConfig();
?>%%

if we want to call the function gettargetpage() we'd better have one:

%%(php)<?
function GetTargetPage() {
	if ($this->HasAccess("read")) {
		if (preg_match("/\A\s*=>\s*(.*)/", $this->page["body"], $matches)) {
			// patterns of forced links and wikiwords (without the commas) are german umlauts really enough?
			preg_match ("/^(\[\[.*?\]\]|[A-ZÄÖÜ][a-zäöüß]+[A-Z0-9ÄÖÜ][A-Z0-9a-zäöüßÄÖÜ]*)/", $matches[1], $matches1);
			$target = $matches1[1];
				if ($target_page = $this->LoadPage($target)) {
				$this->redirect_page = $this->page["tag"];
				$this->LoadAllACLs($target_page["tag"]); // isn't loadallacls better a part of setpage()?
				$this->SetPage($target_page);
			}
		}
	} else {
		// no idea why a redirector page should have it's own acls. but if user has no read-access he hasn't ;)
		// in that case, we simply do nothing and let the page fail as usual
		return;
	}
}
?>%%

~& Added fix in ##$this->LoadAllACLs(...)## call, changed ##$target_page## to ##$target_page["tag"]##.
~& Otherwise mysql_real_escape_string complains about parameter being an array.
~& Additionally, the error message in case of missing "read" access rights was duplicated. Removed it from here.
~& Everything else works really fine!
~& -- PhilippAHartmann

the showhandler shall provide a link back to the original page. or we'll never have a chance to change the redirector (of course we would, guess how).

handlers/page/show.php

%%(php)<?
	// ...

	if ($this->redirect_page) {
		print ("<div class='revisioninfo'>Redirected from "); // this div may get it's own class
		print ("<a href='".$this->href("", $this->redirect_page, "redirect=no")."'>".$this->redirect_page."</a>");
		print ("</div>\n");
	}

	// display page
	print($this->Format($this->page["body"]));
?>%%

Test,Page

now any page will be redirected to another when it starts with **=>TargetPage**
