wpf-delete-user-on-tag-update.php

<?php

// Deletes WordPress user when the tag "REMOVE USER" is applied.
// Works when a webhook is received or during a batch Resync Tags operation is run.
// USE WITH CAUTION.

function my_wpf_delete_user( $user_id, $user_tags ) {

	if ( wp_fusion()->user->has_tag( 'REMOVE USER', $user_id ) && ! user_can( $user_id, 'manage_options' ) ) {

		// If this is a webhook WP_User might not be loaded yet
		require_once( ABSPATH . 'wp-admin/includes/user.php' );

		wp_delete_user( $user_id );

		wpf_log( 'notice', $user_id, 'User ID ' . $user_id . ' was deleted by the my_wpf_delete_user() function.' );

		// Don't run any other actions on the user, since they're deleted now
		remove_all_actions( 'wpf_tags_modified' );

		// Add this action back so a batch Resync Tags can delete more users
		add_action( 'wpf_tags_modified', 'my_wpf_delete_user', 1, 2 );

	}

}

add_action( 'wpf_tags_modified', 'my_wpf_delete_user', 1, 2 );

I think

remove_all_actions( 'wpf_tags_modified', 2 );

Should be :

remove_all_actions( 'wpf_tags_modified' );

As all events should be removed, not only the ones with priority 2

@rusuandreirobert. Good catch. For some reason I thought 2 meant remove all actions with a priority higher than 2. Not sure where I got that from as that's clearly not true 🙃

The idea was to let this function continue to run during a batch Resync Tags (on multiple users), in case multiple users needed to be deleted.

Updated the gist. Thanks!
