Gallery v1.4.4-RC2 and Mambo 4.5 problems

I have set up a test site to evaluate Mambo and Gallery. I followed all the instructions for installing Gallery configured as embedded in Mambo, and added Gallary as a Mambo component. URL is:

http://worleyworld.com/mos/

When I log into Mambo as Super Administrator (user: admin) and then attempt to add a photo to an album, or any other Gallery command that uses a popup window, I get the following message in the popup window:

"Gallery seems to be inside Mambo, but we couldnt get necessary infos"

I found the offending line in in /gallery/init.php:

/* Session infos about Mambo are available when we open a Popup from Mambo, 
** but content isnt parsed through Mambo
*/
if (isset($gallery->session->mambo)) {
   $mosConfig_host = $gallery->session->mambo->mosConfig_host;
   $mosConfig_user = $gallery->session->mambo->mosConfig_user;
   $mosConfig_password = $gallery->session->mambo->mosConfig_password;
   $mosConfig_db = $gallery->session->mambo->mosConfig_db;
   $mosConfig_dbprefix = $gallery->session->mambo->mosConfig_dbprefix;
   $MOS_GALLERY_PARAMS = $gallery->session->mambo->MOS_GALLERY_PARAMS;
}

if(empty($mosConfig_db)) {
   echo _("Gallery seems to be inside Mambo, but we couldnt get necessary infos.");
   exit;
}

Some additional information -- I installed Gallery in a subdirectory of
Mambo... so the mambo home page is:

/mos/index.php

Embedded gallery home directory is:

/mos/gallery/

Any help would be greatly appreciated....

The problem appears to be where Gallery is attempting to load the configuration.php from Mambo in \gallery\contrib\mambo\classes\mambo.php:

/**
* Loads the configuration.php file and assigns values to the internal variable
* @param string The base path from which to load the configuration file
*/
function _setConfig( $basePath='.' ) {
  $this->_config = new stdClass();
  require( "$basePath/configuration.php" );
  $this->_config->offline = $mosConfig_offline;
  $this->_config->host = $mosConfig_host;
  $this->_config->user = $mosConfig_user;
  $this->_config->password = $mosConfig_password;
  $this->_config->db = $mosConfig_db;
  .
  .
  .
}

This load is failing for some reason.

Once again, I have installed Gallery in a subdirectory of Mambo at /mos/gallery/ - would this cause a problem ??

I just upgraded to the latest, v.1.4.4 -- and I get the SAME cryptic error message in popups while Gallery is embedded in Mambo:

Gallery seems to be inside Mambo, but we couldnt get necessary infos

FYI - PHP is setup with register_globals = On

Also - I just noticed, when I open an album the follow error appears at the bottom of the page:

Error: Requested index [0] out of bounds [1]

I added:

php_flag register_globals off

to .htaccess in /big/dom/.../www

Same results.

RELEASE = 4.5
DEV_STATUS = Stable
DEV_LEVEL = 1.0.9
CODENAME = Spider
RELDATE = 28/06/2004
RELTIME = 16:51
RELTZ = GMT

Just to add a "me too!", although in my case this only seems to happen when I attempt to add a photo. All the other popups appear to work, and I'm not getting the error message at the bottom of the page that bworley61 mentions.

However, the photo upload works fine if I use the java applets, I only get this error when I try to use the form method of uploading.

This is using the latest stable release of Mambo (4.5.1.0.9) and the latest CVS build of Gallery (1.4.5.cvs.b81).

It's hardly a "me too" if you're not having the same issue.. ;)

What IS happening?

It is if I am getting the same error message as the starter of this thread :P
Gallery seems to be inside Mambo, but we couldnt get necessary infos
As I said, the only difference is that it only happens when I try to use the form method to upload. The applets work fine.

Oh and a bit off topic, but:
I changed the function makeGalleryUrl() a bit to prevent headers, footers and menu to appear in editing popups (the ones you get when selecting image options instead of album options). Because these url's do not contain the type=popup parameter.. My fix for this:

util.php line 1393

case 'mambo':
				$args['option'] = $GALLERY_MODULENAME;
				$args['Itemid'] = $MOS_GALLERY_PARAMS['itemid'];
				$args['include'] = $target;

				/* We cant/wantTo load the complete Mambo Environment into the pop up
				** E.g. the Upload Framwork does not work then
				** So we need to put necessary infos of Mambo into session.
				*/
				
				switch($target)
				{
					case 'edit_caption.php':
						$mamboPopup = true;
					break;	
					case 'edit_thumb.php':
						$mamboPopup = true;
					break;	
					case 'rotate_photo.php':
						$mamboPopup = true;
					break;

					break;		
					default:
					  $mamboPopup = false;
					break;
				}	
				
				/* We cant/wantTo load the complete Mambo Environment into the pop up
				** E.g. the Upload Framwork does not work then
				** So we need to put necessary infos of Mambo into session.
				*/
				
				if ((isset($args['type']) && $args['type'] == 'popup')) {
					if ($target='add_photos_frame.php') {$target= $gallery->app->photoAlbumURL . "/index.php";}
					else {$target= "index2.php";}
					if(!isset($gallery->session->mambo)) {
						$gallery->session->mambo->mosConfig_host=$mosConfig_host;
		                	        $gallery->session->mambo->mosConfig_user=$mosConfig_user;
	        	        	        $gallery->session->mambo->mosConfig_password=$mosConfig_password;
	                		        $gallery->session->mambo->mosConfig_db=$mosConfig_db;
	                		        $gallery->session->mambo->mosConfig_dbprefix=$mosConfig_dbprefix;
		                	        $gallery->session->mambo->MOS_GALLERY_PARAMS = $MOS_GALLERY_PARAMS;
					}
				} else {
					if ($mamboPopup){$target = 'http://www.gagel.nl/index2.php';}
					else {$target = 'index.php';}
				}

			break;

I've started using Mambo on a personal site and have done a LOT of tweaking to make 1.4.5 completely Mambo-compliant. To my knowledge, the code in CVS has no remaining issues with popups.

Sadly, there's no easy way to back-port these fixes to make available in 1.4.4 - they're fairly extensive and cover a lot of different places in the codebase.

The hack above probably will not work, since it fails to set the necessary information used by Gallery (the large 'gallery->session->mambo' block, immediately above).
