how to create channel based template callback
by wang zifeng 01 Oct '09

01 Oct '09

Hey Guys, first I am new to drupal development and try to learn everything about drupal by scratch. My questions might be easy to you but still hard for me, so any reply is welcomed and appreciated. Recently, I am going to create a customize module that to show all the blog members with their avatars triggering by hook_menu ‘?q=blog’ path. I write the code as what the drupal module development guide taught, first to use hook_menu to route the path as well as the callback function, then use hook_theme to state the template, and then use theme() function in the customize function to call template, last is use template_preprocess function to create the variables before it pass to template file. But I found, all the variables that passed to the template file was packed into ‘contents’ region finally and placed into the template file. In other words, I can’t change the variable into other region, so that let me create a fully customize template for a specific path. For a clearer understanding of my problem: For example, like the difference between page.tpl.php and page-front.tpl.php, the second one could be fully customized with regions. If I want to call page-blogmember.tpl.php trigger by ‘?q=blogmember ‘ to show all the blog avatars but with a fully customized region template, how can I do. Like creating customized channel by ?q=video or ?q=game. Thanks Frank

Calling all database gurus, especially those who have been involved in running master/slave replicated sites before. We have an important decision yet to make regarding the database layer and we have a limited amount of time left in which to make it: Specifically, just how extensively are we going to use our new integrates master/slave replication capabilities.

Drupal Association support for code sprints--comments and help needed
by Nedjo Rogers 29 Sep '09

29 Sep '09

The Drupal Association has a small budget this year to support Drupal code sprints and we're looking for help in deciding how best to use it. We've put draft guidelines for Drupal Association sprint funding at http://groups.drupal.org/node/27506. If you're interested and have a moment, please either post your comments or make your suggested edits. We also need a few people who are able to both provide some support to sprint organizers and help decide how to spend sprint funds. If you can help, please join this new group http://groups.drupal.org/sprints and contact me http://groups.drupal.org/user/426/contact so I can add you as a group admin. Some short term work will be improving the documentation on organizing sprints at http://drupal.org/node/247982 and evaluating a request for support for the upcoming NYC media sprint, http://groups.drupal.org/node/26824. Thanks! Nedjo Rogers

How to process "CCK Input Elements" input
by Ernst Plüss 29 Sep '09

29 Sep '09

The "CCK Input Elements" module allows to add form fields to a cck node. This makes it possible to use a cck node like a webform. Or explained differently: CCK Input Elements makes it possible to have the cck field values not filled in by the node author but the node viewer. My question is: The module doesn't provide any possibility to process the values entered by the node viewer. The description just states that this has to be done by an other module. Could someone point me to such a module or tell me how to process the values? In particular we'd like to send an email containing the user entered values and some other cck field values of the node. Thanks for taking your time! Best Regards Ernst

Translating database fields
by Jeremy Andrews 25 Sep '09

25 Sep '09

Hello, I'm looking for advice on the proper way to resolve this issue: http://drupal.org/node/571742 Summary: The support module [1] defines four default states ("new", "active", "pending", "closed") and four default priorities ("low", "normal", "high", "critical"). These fields are defined in the database to allow the easy creation of custom states and priorities. Because of this, I'm unsure on how to correctly make them translatable. The t() api documentation page [2] explicitly states, "however tempting it is, custom data from user input or other non-code sources should not be passed through t()." It goes on to explain that doing so can lead to orphaned words, mistranslation of non-English words, etc. My question then is, what is the correct way to make these states and priorities translatable? Yes, they can simply be changed in the database if you'd like to change them to another language, but some websites want the ability to translate them into multiple languages. If replying, please do so in the issue linked above. Thanks, -Jeremy [1] http://drupal.org/project/support [2] http://api.drupal.org/api/function/t/6

Additional user account field
by Dayton Perkins 24 Sep '09

24 Sep '09

I am doing a networking site for some one that is targeting college students. It is important that they have a campus associated with their account. I need a little advice as to how best to approach this. I have a database table of campuses that includes a state field. My first take was to add some JavaScript in the registration form. Users select a state from a select list, which uses AJAX to populate a div with a list of links for that state. Choosing a link then in turn gives a visual indication that a campus has been chosen and populates a hidden input value which was empty, etc. etc. This was not too tough using jQuery and what have you. I used something like this: function campus_validate($form, &$form_state){ if($form_state['values']['campus']==""){ drupal_set_message(t('Please select a state and campus')); return false; } return true; } function user_form_alter(&$form, $form_state, $form_id) { if ($form_id == 'user_register') { $form['Personal']['campus'] = array( '#type' => 'hidden', '#default_value' => "", '#required' => TRUE ); // the following are not correct, but the idea is I need to validate the extra fields I am adding. I can muddle through these. $form['Personal']['campus']['#element_validate'] = array('campus_validate'); // $form['profile_sex']['#element_validate'] = array('sex_validate'); } } So I think you can see where I am going with this although it isn't complete. The next thing I want to do, is I prefer to add a tab for editing the users' campus. I prefer this to adding to the user/edit form. Once again, I will need to have a state select that will use AJAX to query and provide a list. Fortunately, I can probably reuse a lot of the code from the registration form. Can someone please suggest how to add a tab to /user, and if you have any suggestions as to making this less labor-intensive, that would be super! :-) If the whole thing should be tossed, and go with multi-step submissions, please point me the right way on that. Thank you so much.

views: translate alias to real field
by Lluís 24 Sep '09

24 Sep '09

I am developing a module to allow operations between fields; it is similar to views_calc but I use another approach to solve problems with "agregated" fields. So right now I use group by and I get: SELECT a AS a1, SUM(b) AS b1, SUM(c) AS c1 FROM {table} GROUP BY a I want to get SELECT a AS a1, SUM(b) AS b1, SUM(c) AS c1, (SUM(b) - SUM(c)) AS minus FROM {table} GROUP BY a right now my module just get: SELECT a AS a1, SUM(b) AS b1, SUM(c) AS c1, (b1 - c1) AS minus FROM {table} GROUP BY a any hint of how to get "original field" from alias? -- *La vida és com una taronja, què 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.

Creating recordset displays
by Raja Sekharan 24 Sep '09

24 Sep '09

Hi all, In many applications I create I find myself doing just one thing - create CRUD interfaces in the admin panel. So far I have been writing code to generate the list of items and everything. Is it possible to create a recordset form using any API in drupal? Here is what I want to do: I want to generate a list for my entities [for example products]. It should be very similar to the Gmail inbox - with a checkbox next to each entry and the ability to sort according to any field. Users should be able to check a set of items and select a drop down menu to perform some action. This should be a form of course. If this isn't possible with the Drupal API out of the box I'd be happy if you can give me a brief outline of how this can be achieved. Thanks in advance.

You can do the opposite, define a tt function if the module doesn't exist, it keeps your code cleaner Met vriendelijke groeten, Peter Droogmans Attiks Ketsstraat 94 2140 Borgerhout peter(a)attiks.com 03-288 61 17 0497-44 44 77 -----Original Message----- From: mark burdett <mfburdett(a)gmail.com> Sent: woensdag 23 september 2009 18:40 To: development(a)drupal.org <development(a)drupal.org> Cc: jeremy(a)kerneltrap.org <jeremy(a)kerneltrap.org> Subject: Re: [development] Translating database fields On Wed, Sep 23, 2009 at 7:42 AM, Jennifer Hodgdon <yahgrp(a)poplarware.com> wrote: > There's a whole section in the Handbook on how to do this: > http://drupal.org/node/303984 This is the specific page I used recently, http://drupal.org/node/304002 "Making your custom data translatable" Littering your module with if (module_exists('i18nstrings')) isn't so nice, so I'm hoping that a future version of core will provide a real API for string translation..
