Modified links pointing to docs server This action is meant as a module for the
UserAdmin tool.
To use it as a standalone action simply add:
{{usercomments user="UserName"}} in the page body.
This action displays a list of pages commented by the current user or by any other registered user specified either via a
user action parameter of via a
user GET variable . If no user is specified and the current user is logged in it displays a list of comments by the current user.
Save the code below as
actions/usercomments.php.
The action
Current version: 0.4
Changes:
- Added documentation header;
- Initialized variables;
- User is checked in the following order: GET parameter, action parameter, current user;
To do:
- (Optionally) create a config option allowing admins to decide whether users can display a list of comments posted by other users;
actions/usercomments.php
<?php
/**
* Display a list of recent comments posted by a user.
*
* This action can be used to display a list of comments posted by a specific user. It
* accepts a user value both as an action parameter and as a GET parameter. The
* specified user must be an existing user. If no user parameter is specified
* or the specified user is invalid, an error message is printed. If no user parameter
* is specified or the specified user is invalid, and the current user is logged in,
* the action will display a list of comments recently posted by the current user.
