Hi I have a form which silently registers a joomla user.
The form has the usual username, password, email fields which are mapped
The problem is that some users are already registered on the site and cannot therefore fill out the form.
Is it possible to
1. Hide the username / pass fields if a user is logged in and capture the email field dynamically
2. Use conditional fields to hide the username and password fields if a user has not registered previously

Currently using conditional fields the form still asks for input on the hidden fields.

Thanks for any help

You can approach your scenario in the following way. Grab the username/email using the method provided in the documentation :
http://www.rsjoomla.com/support/documentation/view-article/77-display-php-variables-by-default-when-form-is-shown.html

Next step would be to create a script that checks it's value so it can hide the unwanted fields.

Keep in mind this is an example and not a solution.

Insert this in the default value of the username field:
//<code>
$user = JFactory::getUser();
return $user->get('username')
//</code>

Head over to CSS and Javascript section and insert a code like the following (you will need jQuery):
<script>
jQuery( document ).ready(function() {
	if (jQuery("#name_of_username_field").val().length > 0){
		jQuery( ".class_of_the_username_field" ).hide();
	}
});
</script>

Next thing on the list is to stop the mapping from happening, in the scripts called after form process, insert the following code:
if ($user->get('id') > 0) {
	$mappings = array();
}

Hi,

I hope that somebody is still reading this post. I don't understand what to put instead of "jQuery( ".class_of_the_username_field" ).hide();"

The field I want to hide is named "Account" but there is no class. So what do I put instead of .class_of_the_username_field?

Thanks and regards,
Uwe
