To change content of registration mail :

To change conent of joomla registration mail follow the below steps:

Suppose we need to add ‘city’ field to the mail content

1. First goto components –> com_user — > controller.php

2. Findout function register_save()

Below the line $document =& JFactory::getDocument();

Add following line for city

$city = JRequest::getVar(‘city’);

3. Now in the same function (function register_save())

Below the line $user->set(‘gid’, $authorize->get_group_id( ”, $newUsertype, ‘ARO’ ));

Add following line for city

$user->set(‘city’, $city);

4. Now Findout function register_save()

Below the line $username = $user->get(‘username’);

Add following line for city

$city = $user->get(‘city’);

5. Now in the same function ( function register_save())

Find out the foreach statement at the end of page there you need to change the code as follows:

foreach ( $rows as $row )
{
if ($row->sendEmail)
{
$message2 = sprintf ( JText::_( ‘SEND_MSG_ADMIN’ ), $row->name, $sitename, $name, $email, $username, $city);
$message2 .= “City:”.$city;
$message2 = html_entity_decode($message2, ENT_QUOTES);
JUtility::sendMail($mailfrom, $fromname, $row->email, $subject2, $message2);
}
}

Please note the $city field in above code.

6. Now goto path language –> en-GB –> en-GB.com_user.ini

Here find out variable SEND_MSG_ADMIN ( nearly at line no. 117, this will only change content of mail going to admin )

Hello %s,\n\nA new user has registered at %s.\nThis e-mail contains their details:\n\nName: %s\nE-mail: %s
\nUsername: %s\n\nCity: %s\n\nPlease do not respond to this message.
