The template file responsible to output the user's name is located at /components/com_easysocial/themes/wireframe/users/default/items.php and you could play around with the result.

Example:

[gist]
<?php

var_dump($user->getFieldData('JOOMLA_FULLNAME'));

?>
[/gist]

The keyword JOOMLA_FULLNAME is taken from http://take.ms/5OhWJ

Unfortunately I don't have that directory as maybe is version 2

I have the following.

see attachment.

I simply would like to invert wieving the first name with last name in the following attachment (list of all user).

as far as I undestood the 2 field become one field,

The original mistake was made on registration while fist name as first field and last name as registration, So the results of the single field will be with last name.

I corrected now to sho and register first name in both and I think I will have to invert manually the field the few user has been registred in order to uniform the future registreant user,

Do you agree with my analisys .. correct the registration and swap the fist name with Last name manually?

Best Regards

If you are on 1.4, you need to look into this template file, /components/com_easysocial/themes/wireframe/users/default.list.php

Your algorithm in swapping names by space is not correct because if a person's first name has 2 words, there is no way to properly know which is the real / last name .

For instance, "Di filippo Flaminia", which is his first and last name?
