Require external files from module.install
by Cameron B. Prince 07 Mar '12

07 Mar '12

Hello, I am working on a module with a rather large install file. This module is more like a cross between an installation profile and a set of features than it is a normal module. One of its functions is to create numerous content types and fields at activation. The arrays that are needed to handle this are pretty large and I'd like to store them as multiple external files (one for each content type). The bundle_copy and features modules are being used to create the arrays and import code from bundle_copy is used to process the arrays and create the entities from a master $data array in each file. The code looks like this: /** * Implements hook_enable(). */ function baseline_enable() { foreach(glob(drupal_get_path('module', 'baseline') . '/includes/install/{*.entities}', GLOB_BRACE) as $file) { require_once DRUPAL_ROOT . '/' . $file; /* IMPORT CODE */ } } When the module is enabled via drush the contents of each file are printed to the screen and the $data variable is not populated. When enabled from the UI, there is no output or errors and the module is enabled, but no content types or fields are generated. I thought there might be an issue with glob, so I changed the code to read the directory to this: $handle = opendir(drupal_get_path('module', 'baseline') . '/includes/install/'); while (false !== ($file = readdir($handle))) { if (strpos($file, '.entities')) { require_once DRUPAL_ROOT . '/' . drupal_get_path('module', 'baseline') . '/includes/install/' . $file; } } This produces the same results. Can someone help me understand what's going on here? Thanks, Cameron

resetting a form
by Si Hobbs 07 Mar '12

07 Mar '12

Hi I am doing an ajax callback, and I want to return a fresh version of a form as content. This is after the form has successfully submitted. So instead of something like: return 'Thanks for your submission'; Which works, I want to do: return 'Thanks for your submission' . drupal_render(drupal_get_form('foo')); However when I get that that form, it is not fresh. The form system reprocesses the form, re-runs the submit handler, and returns a form with the $form_state['values'] all populated. So, I've been trying to work out how to reset the form. For example, this sort of thing doesn't successfully clear the form: cache_clear_all('form_' . $form_state['values']['form_build_id'], 'cache_form'); cache_clear_all('form_state_' . $form_state['values']['form_build_id'], 'cache_form'); drupal_static_reset('drupal_retrieve_form'); Thanks for any tips.

Remove Meta Tag Generator
by webmaster 05 Mar '12

Hi, I noticed that by default this tag is written: <meta name="Generator" content="Drupal 7 (http://drupal.org)" /> I'm perplexed about that and I discover that someone else is sharing my point of view: http://drupal.org/node/982034 Do you think it would be possibile to add an option in the admin panel to switch off this feature? Regards, Domenico

write a simple field type for CCK
by 郭赞 29 Feb '12

29 Feb '12

Hi all, I'm new to drupal module development, and want to write a simple field type for CCK, just to give a list for user to select, and then store the value. Drupal Verison is 6.22 To make it simple, I only write some hooks that I think may needed in the module.... and things get wrong, the row in the table is created in the database, but the field is not able to store data in the database, when I click submit, the page comes to be blank. Here's the code for zebra.module. Did I forget some thing, thanks for your help. <?php function zebra_field_info() { return array( 'zebra' => array('label' => 'Zebra field',), ); } function zebra_field_settings($op, $field) { switch ($op) { case 'database columns': $columns['value'] = array( 'type' => 'varchar', 'length' => 255, 'not null' => FALSE, 'sortable' => TRUE, ); return $columns; }; } function zebra_field($op, &$node, $field, &$items, $teaser, $page) { switch ($op) { } } function zebra_widget_info() { return array( 'zebra_widget' => array( 'label' => 'Zebra Widget', 'field types' => array('zebra'), ), ); } function zebra_widget_settings($op, $widget) { switch ($op) { } } function zebra_widget($op, &$node, $field, &$items) { $element['value'] = array( '#type' => 'select', '#title' => t($field['widget']['label']), '#default_value' => variable_get('zebra_widget_value', '0'), '#options' => array('a', 'b', 'c', 'd'), ); return $element; } thanks, -- Zan Guo E-Mail: guozan523(a)gmail.com

>> This list is for Drupal core development, > > Where, then, should those seeking help with module development turn? > There's a themes list, but not one for modules. > John Summerfield This list was originally for core development. The core developers have (for understandable reasons) decided that all public core development conversations should take place on d.o or g.d.o. As such this list has no real point without changing its raison d'etre. For what it's worth, I'd be happy for this to be the list that handles more technical activity than support (e.g. if you're writing a custom module and are having difficulties with hooks or the API etc) and accept that there will be some grey areas with the support list, which could be more installation/how do I do this orientated.

by Vaibhav Jain 27 Feb '12

27 Feb '12

Hello Guys, I am planning to allow some users to add users to the site. The only concern is I want them to select only one user role, so, instead of a checkboxes, i want a select list or radio buttons. It can be achieved via form alter, but just wanted to know if there is any module available for this I am on Drupal 6. -- Regards, Vaibhav Jain

Re: [development] OOP
by Ashraf Amayreh 23 Feb '12

Hold on your horses. First off, I don't think object oriented is ALL bad. Some things naturally map to objects like user, node, menu, etc, what I am talking about is trying to fit everything into objects. I don't think anyone can argue that object oriented is also equal to bloat. I need a user's name, I load a user object from a user ID which does a million queries or so. As Joe Armstrong, the inventor of Erlang put it: "The problem with object-oriented languages is they've got all this implicit environment that they carry around with them. You wanted a banana but what you got was a gorilla holding the banana and the entire jungle." When an addition application turns into two objects from the Integer class using the + method, and when some wise-ass architect wants you to objectify everything, it does get quite ridiculous. Of course not to mention the 10 times CPU and memory resources used to achieve it. Finally, I don't think many will disagree that when you start thinking about a problem and its solution, you don't start thinking objects. Would love to get the opinions, or better yet, the experience of people who've read others' code written functionally vs OOP. Again, we're not talking about small systems or lousily written ones, but large enterprise systems. I for one get driven crazy following classes, inheritance and finding that each variable is a new class somewhere that's an aggregate of 10 other classes that I have to understand to debug a simple problem. It could just be me of course :) -- Ashraf Amayreh CEO | O-Minds Cell. 962 78 8099997 Tel. 962 6 5655150 Fax. 962 6 5675150 Skype: aamayreh www.o-minds.com web development | web design user experience | branding design Connect with us on Twitter http://twitter.com/ominds Connect with us on LinkedIn http://www.linkedin.com/in/aamayreh

OOP

Was trying to explain some object oriented voodoo to someone who asked me about it (don't get me wrong, I hate OOP). So while searching for an article to get him off my back I stumbled on the following which I thought might be a short and interesting read: http://en.wikipedia.org/wiki/Object-oriented_programming#Criticism Best Regards, -- Ashraf Amayreh CEO | O-Minds Cell. 962 78 8099997 Tel. 962 6 5655150 Fax. 962 6 5675150 Skype: aamayreh www.o-minds.com web development | web design user experience | branding design Connect with us on Twitter http://twitter.com/ominds Connect with us on LinkedIn http://www.linkedin.com/in/aamayreh

form_set_error and updating form values
by Athanasios Velios 21 Feb '12

21 Feb '12

Hello, I am trying to alter a form (uc_cart_view_form) with various input fields (Qty for products). In template.php I am adding some extra logic which applies across a selection of these fields. Once the logic is checked I need to display an error message. I am using form_set_error to show the message. The problem is that the user then updates the input values and updates the form, but the new figures are not taken into account. They are shown in the form, but not used in my template.php extra logic. drupal_set_message allows the new values to work but the message appears twice and it does not, obviously, link to specific fields in the form which are problematic. Setting form_state rebuild to true before form_set_error does not have an effect. Any ideas of what needs to be done for these values to be taken into account with form_set_error? Thanks Thanasis
