re: imagefield / imagecache
by Darrel O'Pry 07 Jul '06

'imagefield'[1] is its own project. If you've been experimenting with cck and imagefield, please post issues to the 'imagefield' project. I'm going to keep it on its own until JonBob comes back and includes it in the mainline cck. imagefield requires the cvs HEAD version of cck. 'imagecache'[2] is a dynamic image resizer and caching tool. I use it with imagefield for thumbnail generation so I don't have to track data about derivative media in the database. I generate and trash as needed. It requires .htaccess and clean urls to function properly. The current cvs version is free of the DOS exploit in the prior version and allows multiple actions to be performed to create a derivative image. Only scale and resize are implemented. I'd appreciate feedback/patches/bugs if you play. *note: recent security fixes seems to have broken the preview feature in 'imagefield' when using clean urls. To enable previews, in the .htaccess in your files directory, comment out RewriteEngine Off, and add +FollowSymlinks to the Options line. ciao. .darrel.

hook_block can set properties (weight, enabled, etc.) for blocks
by Nedjo Rogers 06 Jul '06

06 Jul '06

A quick FYI for module authors. As of 4.7, we can set all block properties except theme in hook_block (instead of, previously, just 'content' and 'subject'). This is a change that was part of the block region patch. So, for example, you can give your blocks an explicit weight, enable them, limit them to given pages, etc. Example: $block = array('weight' => -6, 'enabled' => 1, 'region' => 'content', 'subject' => t('Example')); $block['content'] = t('This is an example'); These settings will be registered when the block is first loaded at admin/block, and from there can be changed manually via block administration. Note that if you set a region that isn't available in a given theme, the block will be registered instead to that theme's default region (the first item in the _regions array).

question on page layout
by Josh Milane 05 Jul '06

05 Jul '06

I know this is a very basic question and this may not be the appropriate forum, but: Often when I browse Drupal sites (or really any CMS site), the page is just a bit too wide for my browser and I have to scroll left and right a tad. It actually looks as though it is going to fit but it then widens and does not. Also, many times there is a very long blank space extending downward, such that it makes the page appear empty to the casual viewer. You have to scroll down to find content, apart from menus that may be on the left or right. Are these things preventable? Or, are they to be expected when dealing with CMS tools? I appreciate your time. Josh

Utility module to configure blocks for all themes at once
by Nedjo Rogers 05 Jul '06

05 Jul '06

Some users have complained that block configuration is 'broken' for multi-themes in 4.7, because block status, weight, and throttle settings need to be made separately for each enabled theme. This simple module provides a fix, allowing the configuration of blocks for all themes at once. http://cvs.drupal.org/viewcvs/drupal/contributions/sandbox/nedjo/modules/bl… Enable this module and admin/block will provide global block settings, while block configuration for other enabled themes will allow only "Placement" (selection of region).

node object in hook_block?
by Augustin (a.k.a. Beginner) 05 Jul '06

05 Jul '06

Hello, I see many implementations of hook_block who declare global $user but none with global $node I tried it but $node is still not set, so I cannot access the node object directly. the solution would be to do like in book_hook() and check on arg(): if (arg(0) == 'node' && is_numeric(arg(1))) but it looks like a hack and for what I have in mind, it makes things more complicated. Isn't there a possibility to have directly access to the $node object? How? thanks, Augustin. -- http://www.wechange.org/ Because we and the world need to change. http://www.reuniting.info/ Intimate Relationships, peace and harmony in the couple.

submitting and processing a form!
by Augustin (Beginner) 04 Jul '06

04 Jul '06

Hello, I thought I grocked the new form API, but I have just been pulling my hair trying to do something that I thought would be fairly easy. I guess I still deserve my handle 'beginner' :/ . In the code below, I create a hook_menu() callback to the function formtest() with a form. I want to be able to print some information according to the form that has just been submitted (here, a simple text string), then reprint the form below that. I know that $_POST['op'] is set when I submit (and the process die()s when I uncomment that line), but I can't get the information submitted to be displayed above the form. I have tried using the function formtest_submit() but returning a value there doesn't get the expected result (it seems it's a path callback). I have searched the extensive documentation, but all there is is how to build a form, not how to process and display the information. Am I, for the third time this week, missing something obvious and simple? Augustin. <?php function test_menu() { $items[]= array( 'path' =>'test/formtest', 'title'=>'test form api', 'access'=>user_access('administer test'), 'callback'=>'formtest', 'type'=>MENU_NORMAL_ITEM ); return $items; } function formtest() { $out = 'beginning of output<br />'; if (isset($_POST['op'])) { $out .= 'text entered: ' . $_POST['text']. '<br />'; // the line above doesn't display, no matter what! //die(); } $form = array(); $form['text'] = array( '#type' => 'textfield', '#title' => t('Enter some text'), ); $form['submit'] = array('#type' => 'submit', '#value' => t('Enter')); $out .= drupal_get_form('formtest', $form); return $out; } ?> -- http://www.wechange.org/ Because we and the world need to change. http://www.reuniting.info/ Intimate Relationships, peace and harmony in the couple.

Time for a new chapter of an endless debate
by Karoly Negyesi 03 Jul '06

03 Jul '06

Hi, Drupal uses objects. Reasons are probably lost by now in the ancient past. PHP is still not the best. I can write: somefunction(array('this' => 'that')) while there is no similar construct for objects. Also we use arrays for links, menus, links and soon mails. So, I propose removal of objects on practical grounds: shorter notation and a very little memory gain. If you have an opinion please share but I think we are only furthered by _practical_ viewpoints. No theory can make Drupal faster or lower its memory usage. The change looks big but it's not, it's scriptable and I can whip up such a script in a very short time. Regards NK Ps. Readability issues? I do not think there is any difference.
