When creating wordpress plugins, especially for the public wordpress directory, you must make sure that all plugin data is deleted on plugin uninstall. In this tutorial I`ll show you how to remove the plugins options when user decides to uninstall it.

Using the wordpress api this is a fairly simple task. You just have to create a file called “uninstall.php” with the following contents and put it in your plugin folder.

<?php
if ( !defined( 'WP_UNINSTALL_PLUGIN' ) )
exit;
// Check if options exist and delete it
if ( get_option( 'awp_option' ) != false ) {
delete_option( 'awp_option' );
}
?>

Now when a user uninstalls the plugin it will delete the “awp_option” you should repeat this action for all your options and your house-keeping function is ready.
