Welcome to the Compass Designs website, powered by Joomla 1.5! The goal of this new site is to be the place to bookmark if you are looking for quality Joomla templates, tutorials, news and tips.If you have several Joomla sites you maintain, its worth adding the official Joomla developer blog to your RSS feed collection.
In a more recent post, Wilco Jansen described an important change to how SEF is implemented in Joomla 1.5. The main point is that you will now have to make a database change if you want to upgrade a site from RC3 to a newer version.
The post reads:
Those who followed the development trunk have noticed an addition of a new system plugin. Anthony Ferrara has written this plugin and provided me with the details. This plugin SEF was changed from a content plugin to a system plugin to account for SEF URL issues outside of content.
The change was made because relative links were not resolving properly from modules and templates when SEF URLs were enabled. A system plugin is introduced to take care of these issues. As such, the content plugin SEF is no longer needed.
The changes to the database simple include changing the sef plugin from content folder to system folder, and reordering the system plugins to compensate for the change. The database changes can be made by either placing the migration.php script in the home directory and executing it, or executing the two following queries in MySQL:
UPDATE `jos_plugins` SET `ordering` = `ordering` + 1 WHERE `folder` LIKE system;
UPDATE `jos_plugins` SET `name` = System - SEF, `folder` = system, `ordering` = 1 WHERE element LIKE sef;
For those who want to upgrade from RC3 to this version (and also the upcoming RC4) need to be aware that this patch needs to be included to make the new code base work with SEF. We currently still have a problem with proper URL generation when the legacy mode is enabled, this problem will be fixed as soon as possible.

A little off topic, but what will happen to those who are using say SH404SEF on a 1.0.XX version of Joomla, will we be able to export those links into the new system on 1.5? I'd like to migrate to 1.5 when it becomes stable but this may stop me for a while. |
