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.

Assign one role to a user
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

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
by Ashraf Amayreh 21 Feb '12

21 Feb '12

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

core compatibility in .info files
by Christoph Burschka 20 Feb '12

20 Feb '12

Hi, I just noticed that the packaging script now adds a core compatibility declaration to the .info file, based on the setting in the release (so ultimately on the branch/tag name). Yet the documentation also states that the "core" declaration is "required" (which makes sense since it is needed for developers to deploy from git) while the "version" declaration is "discouraged" because it is added by the packaging script. If .info files are expected, without exception, to contain a core declaration in git, then what is the purpose of the packaging script adding one? Isn't it either redundant, or potentially (if there's a mistake in the release version) disguising an incompatible version as a compatible one until errors occur? Cheers, Christoph

check node_access for all nodes
by Lluís Forns 09 Feb '12

Is there a way to check all nodes permission problems? I know I can use devel node access, but I have around 300.000 nodes. I want to get a list of the "wrong" ones to check where is the problem before rebuild permission. thanks -- *Ser freak no és imprescindible per ser informàtic, però ajuda. *La vida no ha de ser feliç, ha de ser plena. *Abans d'imprimir aquest missatge, pensa en el medi ambient.

I read about this module this week. Subscription does more thing than notifications (for D7), but notifications is compatible with more modules like messaging, og and more.
