The update_url feature allows a plugin developer to specify a url to an xml file containing information about the latest version of his/her plugin.

Important note - Please be aware that early versions of Wolf CMS will keep using the format originally specified for Frog CMS. However, no official schema describing the correct & valid usage of the format has ever been formulated.

Before version 1.0 of Wolf CMS, we will create a full schema which describes all the valid entries in a plugin updates xml file.

In your plugin’s index.php file, make sure you have an entry like:

'update_url'  => 'http://www.wolfcms.org/plugin-versions.xml'

The location or name of the xml file are your choice as long as you make sure the link is valid and unlikely to change in the future.

Note: it is best to choose your location and name wisely. If you change the url in a later version of your plugin, all current users of the plugin will no longer be notified about any updates.

The xml file you point to with the update_url entry should be well-formed and conform to the example structure below. As you may notice, you can add multiple plugin entries in the same file:

<?xml version="1.0" encoding="iso-8859-1"?>
<wolf-plugins>
    <wolf-plugin>
        <id>archive</id>
        <version>1.0.0</version>
        <status>stable</status>
    </wolf-plugin>
    <wolf-plugin>
        <id>comment</id>
        <version>1.1.0</version>
        <status>stable</status>
    </wolf-plugin>
</wolf-plugins>

1. The “status” entry is currently unused but this may change in the future.
2. There is no formal XML Schema (yet) for this file. A formal schema will be defined before the release of Wolf CMS version 1.0.
