On email a day
by Sean Oneill 20 Feb '11

20 Feb '11

Hi all, I'm enjoying the dev posts, but I seem to get 3 or 4 emails per day. There are 3 or 4 posts per email. Is there some way to get one email per day with all the posts? I went to http://lists.drupal.org/mailman/listinfo/development But there doesn't appear to be a settings option available. Any suggestions? Thanks. Sent from my mobile

AHAH with fieldsets not rebuilding correctly
by Jeff Hartman 19 Feb '11

19 Feb '11

Hey list, I've got a couple forms that use AHAH functions to generate a drop down of states/provinces based on the user's selection in a country drop down menu. I'm using a very similar method as is found here: http://drupal.org/node/331941 One form works fine with fields as $form['country'] and $form['state']. The other form uses fieldsets and those fields get renamed and lose their hierarchy after the form is rebuilt. So for example, the following fields start out like: $form['guest'][1]['country'] $form['guest'][1]['state'] $form['guest'][1]['zip'] But after the form is rebuilt with form_builder and drupal_render using: $output = drupal_render($form['guest'][1]['state']); $output .= drupal_render($form['guest'][1]['zipcode']); // Render form output as JSON print drupal_json(array('data' => $output, 'status' => true)); The rebuilt fields are logically placed outside of the fieldset and end up as: $form_state['guest'][1]['country'] $form_state['state'] $form_state['zip'] Thoughts on what might cause that? Thanks for any direction. I've struggled with this for hours! Jeff

Trouble with upgrade paths from different branches
by Fredrik Sandve Kilander 19 Feb '11

19 Feb '11

Hello. I am having trouble with hook_update_N(). My module (yr_verdata) has two branches for D6, and I want to provide an upgrade path from both of these to D7. However, I can't seem to get the correct schema version when upgrading. In my install file i have the following: function yr_verdata_update_7000(&$sandbox) { // Check to see what schema we are updating from. // If we are going from 6.x-2.x to 7.x-1.x, the schema is already ready for // 7.x-1.x so we just update the schema version number. $version = drupal_get_installed_schema_version('yr_verdata', TRUE); if ($version > 6199) { // Updating from 6.x-2.x, no problem. drupal_set_installed_schema_version('yr_verdata', 7000); } else { // Updating from 6.x-1.x, modify the database table. // Some update logic. } return t('Some friendly message'); } The problem here is that drupal_get_installed_schema_version() simply returns 6999, no matter what. What am I doing wrong? I could just remove the update logic that messes with the database table from the 7.x branch doing it all in 6.x-2.x, and require 6.x-1.x users to upgrade to 6.x-2.x before going to 7.x-1.x - but that sounds like a bad idea to me, and just extra work for people who want to upgrade to D7 with this module. Any help is appreciated!

providing example Services communication code for non-Drupal clients
by Blake Senftner 18 Feb '11

18 Feb '11

Hey all, I've developed a REST API using the Services module, and am in the process of writing client code examples. For API clients within a Drupal environment, the routine drupal_http_request() is a real gift. Something as simple as this: $response = drupal_http_request($url, $headers, 'GET'); $data = json_decode($response->data); gives clients my API responses in an easy to use array, with field names and embedded objects intact. For clients outside of a Drupal environment I am learning to use the libcurl php extension so I can provide them with a working example of how to talk to the API. However, I'm not finding any easy way to get the API responses from cURL into an easy to use structure, such as an array. The responses from cURL seem to always be a string, even when I request binary, and not an easy string to parse from looking at it. Maybe it's in some format I'm not familiar... it looks like there's some structure to it, but not clearly obvious, like JSON. What solutions in this arena are people using? With the popularity of APIs now, is everyone on this list using drupal_http_request() and not having to deal with cURL response parsing?

Workflow: staging server, source control, and the files directory
by Andy Fowlston 18 Feb '11

18 Feb '11

Hi all, I have a question about people's practices using a staging server and source control. I'm keen for us to have a sensible workflow while developing sites, and currently we have the following setup. * Developers have local copies of the site where they develop new functionality, which they check in to source control (Subversion). * The staging server has a checked out version of the repository. * The repository has a post-commit hook that automatically updates the staging server. * There are some changes we make directly via the staging server (ie not in code) and for that there's a script that clears caches, dumps the database, and stores that in the repository. (We try to keep as much in code as possible.) Things have been working well so far, but just recently we started adding content to the site (on the staging server). The problem comes with uploading files via the wysiwyg editor, as this bypasses the normal mechanism of checking into source control and letting the post-commit hook update the staging server automatically. So the question is, what's the best way to keep the staging server's files directory synced with the repository? I'd like to keep things as automated as possible. Here's some ideas: * On some event (eg. post-commit, cron) I just do something like a simple svn add files/*. This won't prune nicely though. * Exclude the files directory from source control altogether, and change the local update process to just copy from the staging server's files directory to the local. This would work, just feels slightly wrong to me as the db contains content that refers to the files, and that *is* in source control. * Maybe I could treat the files directory as a vendor branch and use something like svn_load_dirs.pl to try and keep them in sync. I've not used this script before, and don't know if it would manage this simple situation automatically, or if it would need some manual help. I suppose I could also write a script to parse the output of svn st, but as always would prefer to keep the workload as low as possible :) * Nice super simple idea I've not considered?! I'd love to hear what other people in this situation do, or just any ideas at all. Many thanks, Andy . . . . . . .

hook_menu vs path alias Drupal 7
by Deva 17 Feb '11

17 Feb '11

Hi All, I am developing a site in Drupal 7. I have a node with alias /article/hello I also have a hook_menu with "/article/hello" path registered in my module. When i access the path in browser http://localhost/article/hello it shows the node instead of calling "my_custom_function". $items['article/hello'] = array( 'title' => 'Hello World', 'description' => 'Hello world', 'page callback' => 'my_custom_function', 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); I want 'my_custom_function' to get called. Appreciate your help. -- :DJ

D6 node object question
by jeff＠ayendesigns.com 16 Feb '11

16 Feb '11

When I load a node, if my module knows that the content type is selected for use with it, it takes the field name it's supposed to interact with and looks at the field's contents. One site I'm running this on has 8 content types in use. Seven were marked to be used with the module, and for each, if the field were field_image, I would access $node->field_image, and all was well. Today I enabled it using the final content type, and added a field_image to that content type too. The only difference with that one is that it is enabled for use with node block. I find that although other cck fields on the content type are at the $node->fieldname level, the image field does not appear there, but does appear in $node->content->fieldname. So, I'm wondering, should I be looking in $node->content->fieldname on all of the content types instead of just $node->fieldname, and if not, what's going on with this one? -- Ayen Designs 388 Bullsboro Drive #105 · Newnan, Georgia 30263 404-271-9734 Web:ayendesigns.com <http://ayendesigns.com> Blog: theAccidentalCoder.com <http://theaccidentalcoder.com> Drupal: j. ayen green <http://drupal.org/user/367108> (367108) IRQ: j_ayen_green IM (Yahoo) baalwww (MSN) baalwww(a)yahoo.com Skype: ayendesigns | Facebook: ayendesigns | Twitter: @ayendesigns Ayen Designs is the computer services division of

drupal_render() reordering form items
by Leonard den Ottolander.nl 16 Feb '11

16 Feb '11

Hi, I'm trying to create a form with a list of items that I get from a database table. The query elements are sorted reversely to compensate for the fact that element_children($form) that I call later in my theme function starts from the end of the array. After creating the form array I call drupal_render($form). However it appears drupal_render() rearranges those form items before it calls my theme function. This results in a randomly ordered table that I create from the database elements using theme('table'). Working with Drupal 6.2. Since this is a development site all caching is currently disabled and I explicitly cleared cached data via admin/settings/performance as well after I removed table drag items that I temporarily added. I even disabled, uninstalled, then reinstalled the module and refilled the table the module uses. Is there a way to avoid the reordering of (certain) form elements when calling drupal_render()? Or am I forced to do the ordering in my theme function? Regards, Leonard. -- mount -t life -o ro /dev/dna /genetic/research

t() API documentation
by sivaji j.g 16 Feb '11

16 Feb '11

Hello, t() API documentation reads "Avoid escaping quotation marks wherever possible". Below is the snippet from http://api.drupal.org/api/drupal/includes--common.inc/function/t/6 Incorrect: <?php $output .= t('Don\'t click me.'); ?> Correct: <?php $output .= t("Don't click me."); ?> However the core user module's hook_block implementation is following incorrect style. The same is the case with D7 user module as well. I think the purpose of avoiding t('Don\'t click me.'); style is just to make it more readable and easier for translation. Is there any reasons for encouraging incorrect style in core. Please enlighten me on this. -- Sivaji +91 9941 571 690
