Composr Supplementary: How to disable joining

Written by Chris Graham

Potentially Outdated Tutorial

This supplementary tutorial might be outdated as it was written for a previous version of Composr CMS (version 10).


This tutorial explains how you can disable joining of your website. It also is a good example of how to use match-key error messages.
The tutorial assumes that the match_key_permissions addon is installed.

Composr can be customized to disable joining, but this is not a directly configurable option. Instead, webmasters can deny access to the join page in their site.

Follow these steps to set the permissions:
  1. Go to Admin Zone > Security > Permissions Tree Editor.
  2. Select "Join". You can see a green circle next to "Module: join" since the list reflects Guests' permissions.
  3. Then you can change the permission for each usergroup for this :join page in the box given. Use the "+/-" button to select/deselect all the check boxes. Deselect all the check boxes.
  4. Press the "Set" button to save the changes.
  5. You will see a success message on the screen which you can dismiss.
  6. You will see it has changed the colour of the circle displayed next to the "Join" to red, since Guest users cannot access the ":join" page now.

Follow these steps to set a custom error message:
  1. We can customise the access-denied error message displayed in the join page by going to:
    Admin Zone > Security > Match-key page restrictions.
  2. Enter the page name (:join in our case) in the "Match-key" box and a custom message in the "Message" box under the "Match-key permission-denied messages" heading.
  3. Press the "Save" button to apply changes.
  4. We can check this feature by going to:
    http://yourbaseurl/index.php?page=join&keep_su=Guest
    (we are using keep_su to masquerade as Guest, to avoid having to log out).

Now, the page will display your error message and a login screen.
