Mambo and G2 embedding

DrBob, great news! I hope you find some help in the mambo forums to get actual integration (user management) working. In the Embedding & Integration sticky topic and on http://sf.net/projects/gallery/ -> integration/gallery2/ you'll find integrations for xaraya, postnuke, phpnuke, drupal, ... this could make further development easier for a mambo integration.

Ok, as written in my previous post, I had some issues with the gallery layout. I just re-installed everything using MSAS (Mambo Stand-Alone-Server) with todays Gallery G2 build, and now everything is ok

I'll apply the same changes to my live site later tonight so you can all check it out.

I also made a small module for Mambo so you can display the G2 sidebar (attached below). Testing on MSAS did not show any errors but when trying it on my live site, I noticed some things are not going like they should. So use at your own risk :wink:

Valiant, Regarding further integration, I really hope that I gave the kick-of for other people to start working on this (I made some posts on 2 Mambo forums) I am just not proficient enough to start on a real integration (users sync, etc).

Kind regards,
DrBob

cool. Are you sure you don't want to integrate users too? ;)
I'm sure you need some php knowledge to do what you have accomplished here, integrating the users won't be more difficult (the initial synchronization, import, export is a different thing).

Hi Dr. Bob,

Implemented G2 in Mambo 4.5.1b, using Gallery G2.2005-02-09-09-37-20.zip. All looks good so far, however for some reason, the images are just not appearing. Did you run into such problems? Stand-alone, the images appear, however when embedded in Mambo, they do not?

SA = http://thebrennans.ca/gallery2/
Embedded = http://thebrennans.ca/index.php?option=com_gallery2&Itemid=40

Any suggestions as to what i should look for? Do you think the fact that i located my image folder outside of the root have anything to do with this?

BTW, fantastic job on this... Can't wait to see where G2 takes us!!!

Cheers,

g5, DrBob is absolutely with his indications. Only that the relative path shouldn't start with a slash ('/'), it's just "gallery/" without the quotes.

fixed one minor issue with the embedded forum that had been bugging me. In my implementation anyway, I was having problems with the nested tables being more narrow than the rest of the available space. To fix it, I simply went to

< mambo_root >/gallery/themes/mambo_dark/styles/theme.css

and added the last line to the css entry shown here:

#gsAlbumContents, #gsAdminContents, #gsOtherContents {
    border-top: 1px solid #000000;
    border-left: 1px solid #000000;
    background-color: #333;
    width: 100%;
}

and voila, the problem goes away... :D Hope this helps...

drbob:

I'm working on a customization to your integration that forces full-sized images to pop-up in a new window without the mambo toolbars, etc. This is as simple as telling mambo to use index2.php instead of index.php, so I've made a number of changes to the scripts you provided to allow for a detachUri parameter (as of now, the admin scripts capture and display the param and I added a row to the mos_gallery2 table for it, so that part is working...). I'm well on my way to making this thing work, with one exception. I can't figure out how to tell gallery2.php to use the detachUri instead of the embedUri and was hoping you could provide some insight...

As of now, I've updated gallery2.php as follows:

if ( the linky thing somehow tells you its detached ) {
        print '<table width="100%" cellpadding="4" cellspacing="0" border="0" align="center" class="contentpane">' . "\n<tr><td>\n";
                require_once(MOS_GALLERY2_PARAMS_PATH . 'embed.php');
                   $ret = GalleryEmbed::init(array(
                   'detachUri' => MOS_GALLERY2_PARAMS_DETACHURI,
                   'relativeG2Path' => MOS_GALLERY2_PARAMS_RELATIVEG2PATH,
                   'loginRedirect' => MOS_GALLERY2_PARAMS_LOGINREDIRECT,
                   'activeUserId' => '0'));
    }
else {
        print '<table width="100%" cellpadding="4" cellspacing="0" border="0" align="center" class="contentpane">' . "\n<tr><td>\n";
                require_once(MOS_GALLERY2_PARAMS_PATH . 'embed.php');
                   $ret = GalleryEmbed::init(array(
                   'embedUri' => MOS_GALLERY2_PARAMS_EMBEDURI,
                   'relativeG2Path' => MOS_GALLERY2_PARAMS_RELATIVEG2PATH,
                   'loginRedirect' => MOS_GALLERY2_PARAMS_LOGINREDIRECT,
                   'activeUserId' => '0'));
    }

Obviously, there's duplication of the code earlier in the script that retrieves the param, etc. So tell me, Dr. Bob, how do I go about telling the script that it should execute the first block of code and not the latter?

"isDone is not defined, something very bad must have happened."

My admin component is working fine tho.

Hi DrBob, i'm the guy involves in the php-nuke module.
I have also noticed many feedback for my mod related to the chua85 problem.
I have installed a poll on my website, and it results than half of the people are lost ! I think the real problem don't come from the code itself but mostly from a lack of information for the users.

That's why i would like to improve my mod by adding control tests to check params entered by the end user, and also more information on how it works.

Why not sharing this together, our job are quite similar no ?

cheers.

I tried to start with the user integration for Mambo and found the following:

When visiting a mambo site, a cookie is created with the following variables:

• mosvisitor
• sessioncookie
• gallerysid (added as soon as you visit the embedded gallery)

Using some procedures from Mambo, retrieving the current userID/username should not be that difficult. Any hints on how to proceed are welcome

In my embedding component, as a test, I hardcoded the activeUserID to '5' (that's the admin ID of gallery) but now I receive the below error :

Error (ERROR_MISSING_OBJECT) : 5 GalleryUser
in w:\www\gallery\modules\core\classes\helpers\GalleryEntityHelper_simple.class at line 137 (gallerystatus::error) 
in w:\www\gallery\modules\core\classes\GalleryCoreApi.class at line 2157 (galleryentityhelper_simple::loadentitybyexternalid) 
in w:\www\gallery\embed.php at line 155 (gallerycoreapi::loadentitybyexternalid)

in W:\www\Mambo451\components\com_gallery2\gallery2.php at line 69 (galleryembed::init) 
in W:\www\Mambo451\index.php at line 180

What is happening here ?

Also, I enabled the login for the embedded gallery. I can use this to login as the admin. The first page is displayed correctly (so with all the admin options) but as soon as I click on an admin link (add items), I receive a permission denied error. It seems that, somewhere along the way, my login info is lost.

Regards,
DrBob[/]

valiant, thanks for the quick anwser.

As a test, I just manually inserted the mapping in the DB.
Still using the hardcoded activeuserID, I see that I'm recognized as the gallery Admin but only the first time it loads. Again, when clicking any link like edit or add, I receive a permission denied message.

This leads me to think that somewhere on the way, some data is lost (session/cookie ??).

Error (ERROR_PERMISSION_DENIED) :

Mambo has been installed in the [site root]/mambo451 folder
Gallery has been installed in the [site root]/gallery folder

The relative URL I'm using is "../gallery"
The EmbedURI is "index.php?option=com_gallery2&Itemid=41"
The full path is "w:\www\gallery\"

This is an example of the link with this issue:
http://localhost/mambo451/index.php?option=com_gallery2&Itemid=41&g2_view=core:ItemAdmin&g2_subView=core:ItemEdit&g2_itemId=6&g2_return=http%3A%2F%2Flocalhost%2Fmambo451%2Findex.php%3Foption%3Dcom_gallery2%26Itemid%3D41&g2_returnName=album&g2_navId=

Below is the code I'm using for the embedding

require_once(MOS_GALLERY2_PARAMS_PATH . 'embed.php'); 
      	   $ret = GalleryEmbed::init(array( 
           'embedUri' => MOS_GALLERY2_PARAMS_EMBEDURI, 
           'relativeG2Path' => MOS_GALLERY2_PARAMS_RELATIVEG2PATH, 
           'loginRedirect' => MOS_GALLERY2_PARAMS_LOGINREDIRECT, 
           'activeUserId' => '62')); 

valiant, Indeed... stupid me.. I totally forgot about the module that displays the sidebar. I also hardcoded it there and now the admin part works correctly

So.. what should I do next then ?
drumicube, any chance that you could send me your latest code ?

Kind regards,
DrBob

KAC, it's too early to install it. You'd have to download the newest mod files again and again. I'd wait a week or two. But you could help by finding a mambo developer who likes the idea if G2 in mambo and would help with a few things.

This looks like great fun! Thanks for working on this. Does this mean that G2 doesn't have plans to support Mambo natively as with 1.4.x?

Your code would check all these things on every request of a G2 page. But we have to keep performance in mind. And you don't have to check if a user is already mapped on each request (well, you will have to if mambo doesn't allow hooks into the create user function).
As I describe a few paragraphs below, I'd map the existing users all at once in the beginning and map new users right at the moment when they are created (hook into create user function). Then you can assume that all users of mambo exist in G2. Hence, you only have to get the user id of the current user in mambo and use it as activeUserId in the G2 request.

that could be done. I'd do it a little different (as I did it in xaraya). When installing the module, the existing G2 and existing mambo users have to be mapped. (map admin to admin, anonymous to anonymous, ...). There will be some mambo users that don't exist in G2. You'll have to create them in G2. And there may be some users in G2 that don't exist in mambo, create them in mambo and create a mapping.
You'll have to know how to identify the anonymous user in mambo to map it to the G2 anonymous user. In G2, the anonymous user ID is a constant, you can get it via a query.
The same applies for the admin. There may be multiple admins in mambo, right? I guess you can identify the admin by querying for all users in the admin group (same can be done in G2).
And I'd map the existing users based on usernames.

Query the ExternalIdMap for the mambo user id (= externalId).
If it's not in the map, check if a user exists in G2 with the same username
If so, you can either map these two users or create a new user with the same name in G2, probably a bad idea.

No, GalleryEmbed::create/update/deleteUser manage the externalId map.

Exactly. This is the right approach. If mambo allows something like "hook into create, update, delete user functions" then do it. If that is not possible, we will have to find other ways (difficult for update and delete, but quite easy for create).

Good news

A few days I was contacted by Mr_Jinx, one of the developers of Docman for Mambo. He will take a further look into the integration of G2 into Mambo. According to him there are no direct hooks in Mambo for the user creation/update/delete but through a certain way, it should be possible.

So a big thanks to Mr_Jinx

Kind regards,
DrBob

Just a quick message to say that I've successfully embedded G2 (CVS version) into Mambo 4.5.2 using the com_gallery2 component. Not sure what the embedUri should be though. User integration does not work (but reading the above, that was expected ;)). Excellent work DrBob!

seems like embed.php wasn't included -> path to g2 is wrong.

delete please

gsbe, yes and no. Integrations are a little different in G2 than in G1. G2 doesn't have any integration built-in, but it has an interface and an API which should be generic enough to work with all kinds of other applications (custom websites, CMS, forums, ...).

Then there are people like me or DrBob and lots of others who write a specific integration for a specific application. For CMS as mambo or xaraya, these integrations are mostly "modules" as mambo is modular.

So, once DrBob is finished with the mambo integration, you can download his integration code and G2, and it is as if G2 had a built-in mambo integration.

success! ...

G2 alpha 4 vs 17
mambo 4.5.2.1 (patched)

embeds ...doesn't look pretty but embeds!

Hi Guys,
i'm in develop for a website with Mambo. We need a Gallery and like to include Gallery2 in Mambo.
Thanks for the good work until now. Our PHP-develops like to integrate also the user-management of gallery2 into mambo.
I can post their work here, if they are successful.

cu,
Rejay

how close are we to finishing up the final integration points? Also, where does one go to download the latest iteration of the development you guys are doing? I'm essentially running DrBob's second rev of the integration with some small hacks that I've added here and there specifically for my site... I got distracted from stuff that I was doing in terms of user integration and full page pop-ups, so I haven't made any progress there myself. Thanks for all the work, guys... looks like it's going in the right direction

hi funky,

check your paths again carefully, if both installations are functioning the fault probably lies with the path config ...see previous forum page for an example
good luck!
