that was it - i didn't have $Context->Session->Check($Context); in there.

it is working, tentatively. (see below)

but now i'm getting more errors about undefined junk and i feel it has something to do with includes which are coming from another file and not expecting to be inside the extensions folder:

Notice: Undefined property: Dictionary in (my folder)/library/Framework/Framework.Class.Context.php on line 102

Warning: array_key_exists(): The second argument should be either an array or an object in (my folder)/library/Framework/Framework.Class.Context.php on line 102

another stupid question-
$Menu->AddTab("Files", "Files", "extensions/FilesTab/default.php?PostBackAction=FTPList", "FilesTab", '', '4', '1');

why doesn't this add the tab at the right end? grrr

Bergamot · February 2006

I suspect $ForcePosition has something to do with it.

ithcy · February 2006

me too, but that's supposedly the way it's done...

NickE · February 2006

By the way, just for the record, the page manager dosn't edit settings.php file. What you're probably seeing is it reading in the extension file to it can include the other extensions behind it before building the page and exiting.

Mark · February 2006

sorry dude, but I'm way too loaded to figure this out right now. Hopefully tomorrow I will have a clear head.

NickE · February 2006

I don't really know if this is what you're looking for, but if you want to access it like index.php?Page=Whatever, the following worked for me:


<?php
/*
Extension Name: Custom Page
Extension Url: http://lussumo.com/docs
Description: Adds a completely useless custom page.
Version: 1.0
Author: SirNot
Author Url: N/A
*/

if(@$Menu)
{
	$Menu->AddToDelegate('PreRender', 'Menu_CustomPage');
	
	function Menu_CustomPage(&$Form)
	{
		$Form->AddTab('My Custom Page', 'my_custom_page', '.?Page=MyCustomPage', '');
	}
}

if($Context->SelfUrl == 'index.php' && ForceIncomingString('Page', '') == 'MyCustomPage')
{
	class CustomPage
	{
		function CustomPage(&$Context)
		{
			$this->Context = &$Context;
		}
		
		function Render()
		{
			echo('Whatever you want in here');
		}
	}
	
	//include the other extensions before we exit
	$CurFile = 'include($Configuration[\'EXTENSIONS_PATH\']."'.
		substr(strrchr(str_replace("\\", '/', dirname(__FILE__)), 
		'/'), 1).'/'.basename(__FILE__).'");';
	$ExtensionFile = preg_replace("/(.*?)([\r\n]+)/", '\\1', file('./conf/extensions.php'));
	$ArrIndex = array_search($CurFile, $ExtensionFile);
	if($ArrIndex) //shouldn't be 0 anyways, so we don't need ===
	{
		$ArrLen = count($ExtensionFile) - 1; //for the php end tag
		for($ArrIndex++; $ArrIndex < $ArrLen; $ArrIndex++) eval($ExtensionFile[$ArrIndex]);
	}
	
	$Context->Session->Check($Configuration);
	$CustomPage = $Context->ObjectFactory->NewContextObject($Context, 'CustomPage');
	
	$Context->PageTitle = 'My Custom Page';
	$Menu->CurrentTab = 'my_custom_page';
	$Panel->CssClass = 'DiscussionPanel';
	$Body->CssClass = 'Discussions';
	
	$Page->AddRenderControl($Head, $Configuration["CONTROL_POSITION_HEAD"]);
	$Page->AddRenderControl($Menu, $Configuration["CONTROL_POSITION_MENU"]);
	$Page->AddRenderControl($Panel, $Configuration["CONTROL_POSITION_PANEL"]);
	$Page->AddRenderControl($CustomPage, $Configuration["CONTROL_POSITION_BODY_ITEM"]);
	$Page->AddRenderControl($Foot, $Configuration["CONTROL_POSITION_FOOT"]);
	$Page->AddRenderControl($PageEnd, $Configuration["CONTROL_POSITION_PAGE_END"]);
	
	$Page->FireEvents();
	exit();
}
?>

SirNot... thanks! That has almost done it.

in fact there are no more errors - there is only one small problem.
i need the charset for this page only to be iso-8859-1. it was working in the old page because i could set $Configuration['CHARSET'] immediately after including appg/settings.php and before appg/init_vanilla.php.

however, when the custom page is loaded from index.php, those 2 appg files are included before the extension loads, and so the charset in the http header is set to utf-8. when i change $Configuration['CHARSET'] = 'iso-8859-1' in this page, it is changed in the xml declaration only, and that is not good enough for firefox. it's still utf-8 in the header.

can you think of any way around this without adding a conditional (if page is my custom page, change charset) to appg/init_vanilla.php?

again, thanks, your method has helped immensely.

NickE · February 2006

I believe you can just stick a second header() call in right before the class declaration and it'll override the previous Content-Type header set in headers.php. Worked with php5.

Eg.

if($Context->SelfUrl == 'index.php' && ForceIncomingString('Page', '') == 'MyCustomPage')
{
	header('Content-type: text/html; charset=iso-8859-1');
	
	class CustomPage
	{

ithcy · February 2006

really? i'll give that a try.

ithcy · February 2006

that did it! thanks man, you rock. everything works now.

this is a handy extension, so when i add a few more features i'll post it here.

NickE · February 2006

Well, isn't it essentially what the page manager does?

ithcy · February 2006

what? this extension? no, it's an interface to an ftp server.

NickE · February 2006

oh, I thought you meant as a page adder.

ithcy · February 2006

well that part was useful too

Bergamot · February 2006

It would be awkward if this extension was dependant on the pagemanager extension.

ithcy · February 2006

it's not dependent on any extension.

Bergamot · February 2006

I was talking to sirnot; I agree with you :D

NickE · February 2006

Well I wasn't saying it should rely on it, I was just under the (wrong) impression that he was saying he might release the page creation part of it as an extension, and was pointing out it might be somewhat redundant to have two extensions for the same purpose.
