Writing Joomla bridge - User plugin

Question

I want to write a Joomla plugin to connect to user tables in database (one way).

So on new user registration, user will be duplicated and stored also in second table

Answer 1

I have written a plugin for Joomla 1.6 that takes the new registered user's id and puts it into another table. It also deletes the user info from the secondary table if the user account is deleted. This should get you going, have a look at my code below:

This is for a plugin called: plg_foo_user

foouser.php

<?php

defined('_JEXEC') or die();
jimport('joomla.plugin.plugin');

class plgUserFooUser extends JPlugin
{

  function onUserAfterSave( $user, $isnew, $success, $msg ) {
    //JError::raiseWarning(100, 'here1');
    if ($isnew && $success) {
      $db = &JFactory::getDBO();
      $db->setQuery( 'INSERT INTO #__foo_users (user_id) VALUES ('.$user['id'].')' );
      $db->query();
    }
  }

  function onUserAfterDelete( $user, $success, $msg ) {
    //JError::raiseWarning(100, 'here2');
    $db = &JFactory::getDBO();
    if ($success) {
      $db->setQuery( 'DELETE FROM #__foo_users WHERE user_id ='.$user['id'] );
      $db->query();
      return true;
    }
  }

}

?>
