Plugin developers can create new tables in the database, or alter existing tables to add fields.

In this process, it is common requirement to also maintain schema versioning for plugins. Piwik plugins have this built in.

The schema version is the same as the plugin version. When you release a new plugin version you can bundle with it some schema changes.

How to do this:

  • If your plugin has schama changes in version 1.13, create a file in plugins/MyPlugin/Updates/1.13.php
  • This file contains a Updates_1_13 class
  • This class can run PHP code during the update, and you can implement the getSql() method to return sql code to execute.

See an example of Plugin Schema Update in the DevicesDetection plugin here.
