Mambo and G2 embedding

Tried to install '[kings]Egg' version got following error

OK, here is [kings]Egg's version of the component repacked and ready for install. I installed and uninstalled it a couple of time to make sure it worked.

I still have a problem though with logging in as the admin.

Now I get this error:

The standard users login works fine though. Only my admin login is not working.

hello! I have read 11 pages here but have not heard anybody have the same problem as mine. I have fresh mambo 4.5.2 install with fresh gallery from CVS of 2 days ago. the gallery component works fine until i install the sidebar. The sidebar works fine too until i click on the gallery link i created in the main menu.

If i deactivate the module, gallery goes back to working fine.

you can see it here http://www.littledeath.net/mambo

any idea what i might be doing wrong??

i installed the debug module on gallery but not sure how to see it?

anyways..

/home/ldeath/www/littledeath/gallery2/

[kings]Egg, tried your version same error as before, next tried KAC repacked version installation was successful, you can view it HERE

KAC: Thanks for the repack. As for your admin login problems: I assume you're logging in to Mambo with user 'admin'. What's happening is that G2 can't find anyone mapped to admin's user ID so tries to see what's wrong, but finds there IS an entry in the g2_ExternalIdMap table, which must be pointing to nobody...
If you have phpMyAdmin installed:

Look at Mambo's mos_users table, "browse" it, and find what the id of Administrator is (mine is 62)

Now look at G2's g2_ExternalIdMap table and see if there's a corresponding entry with g_externalId set to the same value. If there is, delete it and try to log in as admin again the usual way.

valiant:
Your original code is:

$ret = GalleryEmbed::init(...activeUserId => $uid, ...);
if ($ret->isError()) {
    if ($ret->getErrorCode() & ERROR_MISSING_OBJECT) {

        // check if the there's no G2 user mapped to the activeUserId
        $ret = GalleryEmbed::isExternalIdMapped($uid, 'GalleryUser');
        if ($ret->isError() && ($ret->getErrorCode() & ERROR_MISSING_OBJECT)) {
            // user not mapped, map create G2 user now
            GalleryEmbed::createUser(....);
            GalleryEmbed::init(...,activeUserId => $uid, ....);
        } else {
            // a real problem, handle it, i.e. raise error or echo error message
        }
    } else {
        // a real problem, handle it, i.e. raise error or echo error message
    }
}

My changes would be as follows: check for success return value from isExternalIdMapped and also check for admin trying to log in since they will exist but won't be mapped. If there's a better way please let me know!

$ret = GalleryEmbed::init(...activeUserId => $uid, ...);
if ($ret->isError()) {
    if ($ret->getErrorCode() & ERROR_MISSING_OBJECT) {

        // check if the there's no G2 user mapped to the activeUserId
        $ret = GalleryEmbed::isExternalIdMapped($uid, 'GalleryUser');
        if (!$ret->isError()) {
            // User exists in g2_ExternalIdMap table but the mapping may be invalid
            // take action e.g. replace entry with correct mapping and / or create user            
        }
        else if ($ret->getErrorCode() & ERROR_MISSING_OBJECT) {
            // user not mapped, map create G2 user now
            // also, watch out for admin: they won't be idmapped but they will exist
            if ($uid == $admin_uid)
            {
                GalleryEmbed::addExternalIdMapEntry($uid, $g2adminId, 'GalleryUser');
            }
            else
            {
                GalleryEmbed::createUser(....);
                GalleryEmbed::init(...,activeUserId => $uid, ....);
            }
        } else {
            // a real problem, handle it, i.e. raise error or echo error message
        }
    } else {
        // a real problem, handle it, i.e. raise error or echo error message
    }
}

Hope this helps![/]

[kings]Egg,

Thanks for the suggestion, I will check that out in phpMYadmin.

BTW, my username and password, although I created them seperately, for both Mambo and Gallery is the same.

***************************************************************

Also, attached here is a Mambo module I put together that will display only a random image from the gallery. I didn't like that I had to show all the G2 sidebar info on the Home page. I wanted only the Random Image on the Home page and everything else from the sidebar to come up only when clicking on the gallery link. Looks much cleaner, IMO.

EDIT: Until one of the prgramers fixes the coding here: In order for to work, you will have to download it, extract it, edit the PHP file with your website address, repack it. Then install it in Mambo. SORRY!

I am an idiot. I jus t figured out how to debug.. lol!!

So I have gallery2 configured to use its own database.

The component seems to read the G2 db info from config.php in gallery path so it knows the db info for the gallery and so does the sidebar as long as they're not trying to run together. (make sense?) So I can see them both updating g2_ItemAttributesMap in the proper G2 database but only when running separately.

Now THAT is funny!

As you can see, I don't know anything about programming. Just trying to contribute since these people have given me much. Hopefully one of you can edit the included php file appropriately so it pulls your address. LOL

Hmm... Don't worry, you haven't deleted the gallery admin, just the mapping from the Mambo user to the Gallery admin. If you check the gallery2.php file you should see that I've done a specific test for admin. Is your Mambo admin user actually called 'admin'? If so, then i can't see why the

if ((strcasecmp($my->username, 'admin')==0)

doesn't evaluate to TRUE. And if this test is successful, it should never try to "createUser". You could perhaps try to debug it by putting the following line above the if ((strcasecmp...):

echo $my->username . " evaluates to ";
echo strcasecmp($my->username, 'admin'); //should be 0 for admin user!

It should output "admin evaluates to 0". If you try this, tell me what happens... Of course, you can always manually insert the appropriate externalUserMap in phpMyAdmin but that's cheating [/code]

In reply to valiant:
I interpreted the "embed::init fails and embed::isExternalIdMapped succeeds" case as one where the user has been deleted from G2 using the normal G2 interface - however, the standard delete user function didn't get rid of the external id mapping. At least it didn't for me. In fact, thinking about it, is this a bug in Gallery2 that needs to be fixed? Anyway, that's why I treated it differently - I suppose in the final version this case should never arise unless somebody's been messing around with their database (like I have done )

As far as this goes: if no mapping is detected, your code calls the GalleryEmbed::createUser method to map AND create the user simultaneously. This is great, as long as the user doesn't exist. When I started work on this, my admin user existed in G2 but there was no external id map for it (just like you'd expect). Now when i used your suggested method, embed::init failed (no id map found), then createUser was attempted but failed (ERROR_COLLISION since admin already exists). Which is why I've put the admin exception in: since admin will definitely exist already, we need to create an ID map only - which createUser will not do since it will detect a collision and fail.
There's always a possibility that i've got the wrong end of the stick of course. Please let me know!

KAC: aaaah it all becomes clear. My string test for admin is therefore not the best way to do it. I stupidly assumed that the Mambo admin user was always called 'admin'. I have a feeling i should be checking a different flag ($my->isAdmin or something like that). I'll check it out and fix it later. A quick hack to get it working for you now would be to change the strcasecmp($my->username, 'admin') to strcasecmp($my->username, 'kac') but obviously that's no good for everybody else who wants to use the component

aravot, i fixed mine by just editing mod_g2random.php. simple fix. I wish clicking on the images would redirect to gallery inside mambo, not to standalone..

KAC, lol, i had to laugh out load. I did the same once, but with a ultralow security password for a test install
I'd change my password if I were you, though ;)

so i just moved my gallery2 tables into the mambo database and all is well again. I like the sidebar but.. it's too big for most of the site.

thanks.

Works like a charm! :wink:

[kings]Egg, great work!

nitpicks:
- GalleryEmbed::addExternalIdMapEntry($my->id, $g2user->getId(), 'GalleryUser'); returns also a Gallery Status object, you should check if the function executed successfully.

- same for GalleryEmbed::checkActiveUser($my->id);

- when you do "echo $ret->getAsHtml();". you could add some extra info, such that if someone has this error, you know exactly where it came from.
i.e. echo "unknown error during isExternalIdMapped\n<br>" . $ret->getAsHtml();

- after each echo $ret->getAsHtml();, you have a return statement. but not on line 149. probably you forgot it?

- user album creation:
1. IMO you shouldn't create it yourself. G2 has a user album module and you can it creates useralbums for you when a G2 user is created. See the module details in site admin.
2. It won't create a user album, if the user already existed in G2 and you just do a addexternalMapEntry. Ergo, you should move the user album creation code (if you really want to keep it) directly under the addexternalmapentry call.
3. that way, you also don't do the whole "does the user already have a user album" code on each request.

- css / javascript / page title: can you somehow add css style sheets / javascript / set the page title with the mambo API / can you hack it?
because after the GalleryEmbed::handleRequest() call, you can get the list($title, $css, $javascript) = GalleryEmbed::parseHead($g2moddata['headHtml']);
what you do right now is output html from the <head> part in the <body> part. that is not a correct html page and won't display correctly on all browsers. you should really not just output $g2moddata['headHtml'] directly...

i really like what you've accomplished, it's getting better and better!

KAC, please discuss GR in an appropriate forum thread (there already exist some embedded G2 + GR topics).
If you want something to happen, you better post a message in the GR forum.

full path should be your server path example:
/home/domains/starvingcoder.com/www/test3/gallery2/
relative path: /gallery2
path to mambo: /

You guys with this Mambo/G2 combination,

How are you uploading new pics to your gallery?

Looking at the Gallery Remote forum, it appears nobody has figured out how to send the username and password in the URL address for the embedded Gallery Remote to work.

Meanwhile, I'm disabling the embedding, uploading with Gallery Remote (stand alone mode), then re-enabling the embedding.....kinds sux.

Thanks guys. I used avarot's suggestion for the full path
(/home/domains/starvingcoder.com/www/test3/gallery2/ ) however, mambo is installed under a sub-directory, so i had to use /test3/gallery2. The component is viewable however, the picture links are broken and if i click anything i get a "page does not exist" error. Any suggestions?

My mambo too is installed in sub-directory (sub-domain) here is snap shot of my configuration page and my -> Test Web site

[img]http://webpages.charter.net/osipof/g2/g2sidebar_config.gif[/img]

So, I'm starting to think maybe I have a weird server setup. I've been trying to figure this out for ages. I have G2 installed, and it works perfectly standalone. I installed com_gallery2, and when I try to access the embeded page, it dies after writing the first <table>, <tr>, and <td> tags. You can see this here:
http://www.mishakononov.com/index.php?option=com_gallery2
Working the debug settings and going through some code, it seems to be stalling where Smarty fetches the embedHead.tpl file. What I can't figure out is why. I'm assuming it's not a fault in Smarty, but I really can't figure it out. Help?

Attached is a modified* version of KAC Mambo module that displays only random images from gallery albums, put together by asking for help around various forums namely mambohacks.com and simplemachines.org.

* Following has been fixed.

good job aravot!

valiant, there are three things you can get here that are working and ready for CVS.

1. The "com_gallery2.zip" component that [kings]Egg posted on Apr 19, 2005 - 05:07 PM

2. The "mod_g2_sidebar_updated.zip" module that randycarver posted on Apr 08, 2005 - 08:40 AM

3. The "mod_g2_random_image.zip" module that aravat posted on Apr 27, 2005 - 02:23 PM
