computerminds — Sat, 03 May 2008 07:53:34 +0100

Another quick one this, we recently had a small client experience issues with their Drupal site which was hosted on lycos webhosting. They hadn't changed anything on the site, but suddenly they were getting nothing but 500 (internal server) errors.

Drupal mysql utf8 and latin1 character set issues

computerminds — Sun, 27 Apr 2008 13:25:15 +0100

Upgrading from Drupal 4.6 has always been complicated by issues of character sets, but the Drupal upgrade scripts normally solve most of these problems for us. But when your dealing with a complex upgrade you need a good understanding of how Drupal is dealing with character sets in Mysql.

Drupal Problem with the admin/content/node page filter

computerminds — Tue, 15 Apr 2008 20:51:19 +0100

A rather obscure one this, but we found a problem today on one of our Drupal sites with the filter form on the node admin screen (admin/content/node). Changing the filter settings on the form had no effect, which prevented you from filtering the list of nodes. We tracked the solution down to the $_SESSION array being cleared between page reloads, and a quick google pointed the finger at the Remember me module. Disabling the module solved the problem

Increase the performance of Drupal's ubercart for sites with a large number of products

computerminds — Sat, 12 Apr 2008 22:19:07 +0100

We are in the process of putting together a large (20k products) store with ubercart and ran into some performance issues due to the hook_forms implementation.

Bulk deleting Drupal nodes of a particular content type

computerminds — Sat, 12 Apr 2008 22:08:35 +0100

The Drupal admin interface allows you to delete up to 50 nodes at one time, which is great - but there are times when you it's just not enough and you need to bulk delete many thousands of nodes.

Drupal image assist force a default alt tag

computerminds — Sat, 08 Mar 2008 06:57:56 +0000

We make heavy use of the Drupal image assist module (or img_assist as its known) - but find that its handling of empty alt tags is quite poor. The problem being that if when inserting the image the user does not specify a caption or description then the alt (and title) attributes are both empty.

Multilingual views in Drupal when using i18n module

computerminds — Sat, 01 Mar 2008 17:20:19 +0000

Building multilingual sites in Drupal using the i18n module always throws up a few fun problems to be solved. One of the most awkward being views.

The i18n views integration module does an excellent job of allowing you to return only nodes matching a particular language, but it doesn't help when it comes to translating the view itself - and more importantly allowing a view to site nicely into multiple positions in the menu (one per language).

Drupal themeing : Adding active class to the Drupal primary links

computerminds — Tue, 29 Jan 2008 23:43:48 +0000

This little snippet lives in your phptemplate_variables function and will set a useful 'active' class alongside the not so useful menuid-active class which Drupal assigns to the active primary links


foreach($vars['primary_links'] as $key=>$link){
   if (strpos($key,'-active')){
      $vars['primary_links'][$key]['attributes']['class']='active';
   }
}

Drupal 5.6 bug affects prevents saving of HTML filter settings

computerminds — Sat, 26 Jan 2008 14:52:25 +0000

Just flagging this as a bit of an issue - it appears there is fairly serious bug in the version of the filter module provided in Drupal 5.6 which prevents you from saving changes to the allowed HTML tags

A patch is available on drupal.org but it's quite well hidden! Post number 7 in this thread contains a working patch http://drupal.org/node/208700

An alternative solution is to download the 5.x HEAD http://drupal.org/drupal-5.x-dev) and take the version of the filter module from there

UPDATE This has now been fixed with the release of Drupal 5.7
