global $user unavaialable?
by David Metzler 23 Mar '09

23 Mar '09

I'm working on implementing a new cas_server module that allows drupal accounts to be used as a single - sign on source. I have a drupal 5 site issues a redirect to a drupal 6 site, and when I redirect to that page I don't find that the $user global is populated. Is there some function or include that I should b calling to make sure that this data is there? Code snippet that isn't returning correct data. global $user if ($user->uid) { drupal_set_message('user logged in'); } else { drupal_set_message('User not logged in'); } Note that if I click on any other link in the drupal page. I show as being logged in, but the redirect to this page does not load the $user variable. Developing against drupal 6.10

private areas inside Organic Groups
by Lluís 23 Mar '09

23 Mar '09

I am developing a module to enable private sections inside any organic group. The idea is to be able to create a group and define areas like "paper administration", "human resources", etc... I have created a module to create and a block to choose be able to define "staff roles" inside a OG, so now when a user create a node and have a "staff role" activated, that role should only be visible for users inside this group and with the "staff role" activated. I supose I can achieve this using hook_node_grants and hook_node_access_records, but I don't get how, could anybody give me a hint? My nodes are saved with: realm= 'staff1' gid=4 view=1 update=1 delete=1 function ogsubroles_node_grants($account, $op) { $grup=og_get_group_context(); if ($_SESSION['ogsubrole_active_'.$grup->nid]) { $grants[$_SESSION['ogsubrole_active_'.$grup->nid]] = array(1); return $grants; //sempre hem de retornar alguna cosa per fer que els no valids no es mostrin } $grants['staff1']=array(1); $grants['4']=array(1); $grants['view']=array(1); return $grants; } function ogsubroles_node_access_records($node) { $result = db_query('SELECT * FROM {ogsubroles_nodes} WHERE vid = %d', $node->vid); while ($grant = db_fetch_object($result)) { $grants[] = array( 'realm' => $grant->subrole_code, 'gid' => $grant->gid, 'grant_view' => 1, //$grant->grant_view, 'grant_update' => 1, // $grant->grant_update, 'grant_delete' => 1, //$grant->grant_delete, ); } return $grants; } -- *La vida és com una taronja, que esperes a exprimir-la? *Si creus que l'educació és cara, prova la ignorància. *La vida és com una moneda, la pots gastar en el que vulguis però només una vegada. *Abans d'imprimir aquest missatge, pensa en el medi ambient.

Announcing DRUPAL-7-0-UNSTABLE-6
by Angela Byron 20 Mar '09

20 Mar '09

Hey there, Drupal people! Time for the monthly unstable release! Lots of goodies this time... For module developers who wish to get a jump on upgrading their modules to Drupal 7 ahead of time, check out http://drupal.org/node/224333 for a list of API changes. Remember: there are only 165 days left until code freeze, when we must cease and desist all world domination plans until Drupal 8! http://drupal.org/community-initiatives/drupal-core has a nice list of all the current initiatives going on (feel free to add your own as well!). If you're looking for the places to make the biggest splash, those are them. :) Or, if you're just getting your feet wet with patching and want something a bit easier to cut your teeth on, try tackling one of the issues listed at http://drupal.org/patch/novice ! Friendly volunteers are always available in #drupal in irc.freenode.net to offer assistance. With that out of the way, here are some of the highlights of DRUPAL-7-0-UNSTABLE-6 (full release notes attached at the end). - In JavaScript-y news, Drupal 7 now comes with jQuery 1.3.2 and jQuery Forms 2.21. it's also now possible to use jQuery alongside other JS libraries (Prototype, etc.)! This requires a small change to your JS code that you can do even now in Drupal 6 as a best practice. See http://drupal.org/node/224333#javascript_compatibility for more details. You can also now reference external JS files from drupal_add_js() rather than having to do silly workarounds with drupal_set_html_head(). Yay for consistency! - Massive re-working of image handling libraries (basically ImageAPI in core), which gives us important groundwork towards ImageCache in core http://drupal.org/node/371374 and even possibly ImageField in core. OoOoOoo... :) - The new database system (DBTNG) now supports pager and tablesort queries via "extenders," which means that we can now work on converting pretty much all of Drupal core queries to DBTNG. Feel free to pick off an issue from http://drupal.org/project/issues/3060/term/ 131 if you'd like to get a head start on learning this essential part of Drupal. - For designers, lots of exciting news! First, page.tpl.php now has some nice, cleaner markup to make it easier for CSS designers to jump in and start theming without any PHP knowledge. w00t! Next up: node.tpl.php: http://drupal.org/node/382870. Also, our aging, ugly pals Bluemarine, Chameleon, and Pushbutton have been retired from core so they no longer offend designers new to Drupal and make them think that apart from Garland, all Drupal can ever be is ugly and non- standards compliant. ;) Hooray! Thanks to JohnAlbin, who took a hit for the team, they're still in contrib if anyone needs them. :) - Drupal 6 -> Drupal 7 core upgrades should actually work now without any manual monkeying with settings.php! :) Yay! - A new filter was added which will let you post a link to <a href="[internal:node/123]">About Us</a> and automatically figure out the right path. -Angie

Forms API
by Gordon Messmer 18 Mar '09

18 Mar '09

I'm trying to write a new module, and having some trouble with the forms API. I'm deploying this under Drupal 5. I've been reading the tutorials and documentation for the forms API. A lot of this module is cut and paste from the documentation. I'm able to generate a form properly, and even theme it. It displays properly in my browser. However, when I submit the form, the _submit function isn't called. The code is here: http://phantom.dragonsdawn.net/~gordon/customerportal.module The browser sends the form data via POST, and the web server responds with "200 OK", sending back the form HTML. It doesn't log any errors. I have no idea how to go about debugging Drupal to determine why the _submit function isn't being called. Can anyone give me some pointers?

Loading configuration using 'SERVER_NAME' as opposed to 'HTTP_HOST'
by Adam Cooper 17 Mar '09

17 Mar '09

Hello all, It's a (very) long time since I posted to this list. So please excuse me if I'm breaking etiquette. I'm attempting to set up a development environment that suits my way of working. Using a VMware virtual machine (that is as close a replica to my VPS as possible) I've set up an apache instance and am adding virtual hosts to it as I go. Up until now I've had no issue bring across my current sites. They all are single sites and so have been set up in the 'default' configuration. I can add an entry to my host machines hosts file (say 'sitename.dev') and everything works great. The problem now is that I have come across one of my multisite configurations. I figured I could just set the virtual host configuration to have ServerName as my site name (sitename) and then ServerAlias in the name I would be accessing it as (sitename.dev). Setting UseCanonicalName to 'on' would let me access the site as I would expect. Except, despite this setting SERVER_NAME to the value I expect (sitename) my drupal configuration refuses to load. I took a look in the bootstrap file and found that the configuration directory is loaded from HTTP_HOST. TL;DR. So my question is this, why does drupal load it's configuration using HTTP_HOST as opposed to SERVER_NAME? Surely SERVER_NAME would allow more flexibility and more direct control? Would a patch changing this have any chance of being looked at? Thanks Adam

Best place to store user data
by Steve Yelvington 17 Mar '09

17 Mar '09

Awhile back I wrote a simple module to fetch my Facebook status line, using an open RSS feed, and make a block to display on my blog. The fetched data is stored in cache for a limited period. http://drupal.org/project/fbstatus I've received a number of requests to upgrade the module to support multi-user scenarios. In such a case, cache obviously isn't the right place to put the data. But since there should be no more than one Facebook account per user, it seemed that creating a table (as seen in the Twitter module) would be overkill. So I began looking at using profile fields (requiring profile.module) or the serialized user data. But I'm likely to move the updates into hook_cron, and I can imagine a large site having to step through the whole user base, looking for statuses needing updates. So now I'm back at a discrete table. Is my thinking right?

grepping for relevant functions/lines
by Maggi Federico 16 Mar '09

16 Mar '09

Hello List, I am new to Drupal and new to this list. For research purposes, I am surveying code repositories of the top 10 web applications using a modified version of StatSVN. Basically, I need to track source changes, over releases, in terms of "Lines of Code (LOC) matching a certain regexp". The functions/lines I am interested in are those somehow involved in handling HTTP request/session/response parameters. Of course, I allow a certain roughness in the analysis. I am trying to build a list of such functions/lines. What would you suggest to include? What would you grep for if you want to estimate the functions that are, even indirectly, related to processing of HTTP requests/sessions/responses? Any input is greatly appreciated. Thanks in advance. Cheers, -- Federico

Drupal & Database layout
by Jay Liu 15 Mar '09

15 Mar '09

Hi All, I'd like to write to the drupal database using a Java-Hibernate mapping however, I can't find any database design documentation. I guess I just need to know what inserts into which tables when you create a front page posting. I'm not a php programmer so I don't have an idea how to go about browsing through the code. Thanks

D7 contrib module development
by Marcel Partap 13 Mar '09

13 Mar '09

Hi fellow drupal devs, wanted to bring up a few points about module development for some time and i guess now that module development happens to be the hot topic of the day would be a good time.. While D6 is proving to be a great success and through contrib modules can be flexibly expanded to almost unlimited use case customizations, working with a whole bunch of modules on our site my experience is that quantity is not necessarily a good compensation for quality. Several problems just keep coming up: - modules spamming the watchdog table with E_ALL warnings - modules ignoring the style/documentation guide lines - applied insane programming(TM) techniques - undescriptive module names but by far the most serious one is - duplication (partial feature overlap with existing modules). There might be different perspectives on this but IMHO specifically for D7 this is not a good way to go. An example for this mess is the huge number of competing notification/subscription modules for D6 - each with a destinct feature set and of course incompatible to all others. While competition is a good thing, certainly having multiple similar D5 modules live on and slowly creep up the version ladder while fighting for the same 'market share' is hindering real progress (=feature innovation, code sanity and API excellence) more than it is promoting it. If we want D7 to become *THE* perfect open source CMS, maybe a change in the module development process can help guaranteeing a higher level of code quality. One possible option could be to go some steps towards the linux model, in which all patches have to be signed off by a small team of core developers. Drupal would not have to choose an official team of reviewers though - patches could be confirmed by a simple voting system, in combination with the already working automatic testing. The issue tracking system could be optimized for reviewing/auto testing/auto committing patches (more code centric). However the specific details: the point of that change would be to shift responsibility (=power) from individual module creators to the coding swarm of contributors. This would significantly lower the odds of b(rainde)ad code getting in and hopefully drastically cut down on duplication. Especially because of the to-be-expected great API changes in D7 and the resulting amount of code rewriting that has to be done, wouldn't it be a great point in time to get our act together and come up with a single bind-them-all notification framework? _One_ cleverly designed poll/decision extension? Merging/standardizing the various e-payment modules? Imho taking this direction in the long run will result in more coherent code and enable easier adaption to core API changes, also cutting down on user confusion - furthermore increasing overall D7 r0xorn3ss!
