joomla com_users控制器覆盖

Question

I can't override the controller of com_users (Joomla 3.4). (I want, if a manager can make user registration on the site after when he loged in.So I want to see the registration form, if I loged in the site.)

If I modify the original file, then it works fine, but I don't want to modify the original file. I tried 2 override plugins for this ( MVC override , Override master). These plugins override the file, but after I click the registration button I get the following error message:

Fatal error: Cannot redeclare class UsersController in D:\\wamp\\www\\mysite\\components\\com_users\\controller.php on line 136

It's the same file. I modified the line class UsersController extends JControllerLegacy to this class UsersController extends UsersControllerDefault . Because I read this here . What is the difference? Why doesn't it work this way? :/

Answer 1

1. If you have the MVC override plugin installed be sure to have "Make Extendable" set to yes in the backend (Plugins: System - MVC Override)
2. I advice you to put all overrides (html, code, etc.) in your template directory, so create the controller file as: templates/YOUR_TEMPLATE/code/com_users/controller.php
3. Finally, in THIS controller file you override it like it was mentioned:
   class UsersController extends UsersControllerDefault {

This should do the trick.

Answer 2

This happened to me also. The issue was the that I was also overriding a subcontroller (inside controllers folders)

I had to add

$bufferContent = str_replace('extends UsersController','extends UsersControllerDefault',$bufferContent);
$bufferContent = str_replace('require_once', '//require_once', $bufferContent);

after

$bufferContent = str_replace($originalClass,$replaceClass,$bufferFile);

This is a hack and will only work the com_user override. You need to change the first line to reflect your correct component class.
