Installation and Upgrade Instructions for Wordpress Database Abstraction Plugin
The WP-DB-Abstraction Plugin can only be installed as a
Must Use plugin. This means
that updates and installations must be performed manually and cannot be done using
the Plugin Administration area of your wordpress site.
- Always back up your database before beginning an upgrade or install. If
you are migrating from MySQL to SQL Server, make sure export your database
information as xml.
- Download the latest version of the plugin from the
- Unzip the files
- Find your wp-content folder. The default location is wordpress/wp-content
Make sure this directory is writeable by your webserver
- Put the wp-db-abstraction directory and the wp-db-abstraction.php that
you unzipped into wp-content/mu-plugins If the mu-plugins directory does not
exist, please create it first. It should be parallel to your "themes" and
"plugins" directories in wp-content. If you already had the plugin
installed, simply overwrite any existing files in this directory.
- Open up wp-content/mu-plugins/wp-db-abstraction . There should be a file
called db.php. Copy that file from its current location into wp-content . It
should now be located in the same place as your mu-plugins directory, your
plugins directory, and your themes directory. If you had the plugin
installed previously, simply overwrite the existing db.php file. If you have
a db.php file from a different plugin you'll need to rename the old db.php
($pluginname-db.php for example), copy the new db.php file from
wp-db-abstraction to the wp-content directory, open the db.php file in a
text editor and add include '$pluginname-db.php'; to the bottom of the
new db.php file.
- If you are migrating from MySQL to SQL Server or this is a new
installation please visit
to generate your wp-config.php. Then follow the regular Wordpress
installation steps. If you are migrating, you may then import the xml data
you exported in step one using the Wordpress Administration Area.
- Make sure you have a file called fields_map.parsed_types.php in your
wp-content directory after installation. The plugin will not function
correctly without this file. If your wp-content directory was not writeable
or some other error kept this file from being generated, you may copy the
fields_map.parsed_types.example-3.2.1.php file from
wp-content/mu-plugins/wp-db-abstraction to wp-content and rename it to
