Deleting Profile

Overview

As a site Admin, you can allow users to delete their user accounts. This action, however, requires Administrator action because in the Joomla environment, only the site Admin can delete a user completely. Joomla doesn't have the Frontend capabilities to allow such actions; therefore, when a user '"deletes" an account, it is actually only blocked, waiting for an Admin to complete the deletion process.

Enabling the Option

Navigate to the site Backend.
From the Components dropdown menu, select JomSocial, then Configuration
Under the Site pane, you will see the settings regarding registration and in it, the Allow Profile Deletion option, which is enabled by default.

This will allow the users to have the additional option in the edit profile field to delete their user account.

Deleting an Account

This action must be initiated and confirmed by the user only, by clicking on the option displayed in above the picture, and then confirming the deletion by clicking Yes delete my profile.

After clicking Yes, delete my profile, the user will automatically be blocked (not deleted) and logged out from site with no ability to log back in again.
The email will be sent to the site Admin, notifying the Admin about the user's request to delete his/her profile.

I want my users to be automatically deleted, without admin action

This is not possible in Joomla environment. As mentioned at the begining of this tutorial, Joomla! does not have any Front End facilities to accommodate such action. Since jomSocial relies on Joomla User Object, it is impossible for us to delete the user account from the Front End of the site.
Another things also stops us from implementing this feature. Those are hooks that are triggered when user is deleted
These hooks are triggered only in backend, and are used in JomSocial User Plugin to delete all the trails from deleted user.
