I've created a custom authentication plugin and it works well. The plugin is in the plugins folder plugins/authentication.

Now I face the problem, when I would like to login in my backend, then the plugin will be initiated and my login into the backend fails.

How can I make the plugin only working for my frontend or by using my component?

You can restrict the plugin so that it only gets initiated in the frontend only, by using:

$app = JFactory::getApplication();

    // Your plugin code

or to initiate for a specific component

$jinput      = JFactory::getApplication()->input;
$component  = $jinput->get('option');

if($component == 'com_content')
    // Your plugin code

Change com_content to the component you wish to check for.

Hope this helps

  • The plugin is created along the advisory of docs.joomla.org/…. In the plugin, there is a function 'onUserAuthenticate' but I did also several functions in addition. I've used your first solution. I did this solution in every function of this plugin. Iam not sure, whether I did the most elegant implementation, but otherwise I came up with errors. Thx

  • @Perino - oops, I just spotted a mistake in the 2nd code snippet which I've now updated
