Examples:
Assuming that you want to create an e-mail form component, and by default, if the user is logged in, to enter it's registration e-mail in the Email field. Here's how to do it:

1. Create a textbox component
2. In the Default Value, type this code:

//<code>
$user = $RSadapter->user();
return $user;
//</code>

This piece of code (including the //<code> tag) loads the user information in the $user variable. Here's what you can use:

* $user = user id -->OK
* $user = the username -->OK
* $user = registration full name FALSE
* $user = registration email -->OK

Help please

Hello,

In order to retrieve the email of the logged in user and display it in one of your form's fields please try using the following code:

//<code>
$user =& JFactory::getUser();
return $user->email;
//</code>

In addition to the user email you can also retrieve the user's name, id, or username. You just need to replace email with your desired information, for example:

return $user->id;
