Thanks erez213 for your posts, but they are about adding a custom field on the profile page and that's not what I need.. I 'simply' want a form on the front-end of a regular page to update the User's profile (currently logged in): this field is already in the profile: "Zip".

add the following code to your functions.php:
function add_form($content) {
global $current_user;
$page_name = 'thanks-you';
$key = 'user_email';
$success = 'The zip Code chagnged...bla bla.';
if(is_page($page_name) && is_user_logged_in()){
get_currentuserinfo();
$user_info = get_userdata($current_user->ID);

if(isset($_POST['zip'])){
update_usermeta( $current_user->ID, $key, $_POST['zip'] );
$content .= $success
} else{
$zip = $user_info->$key;
$content .= '<form method="post"><input type="text" name="zip" value="'.$zip.'" /><input type="submit" value="Update" /></form>';
}
}
return $content;
}
add_filter('the_content', 'add_form');
chane the value of the following variables:
$page_name to the name of the page where you want to show the form
$key to the name of the zip in the wordpress admin panel
$success to the text that you want to show on success

function pypy_add_form($content) {
global $current_user;
$page_name = 'thanks-you';
$key = 'user_email';
$success = 'The zip Code chagnged...bla bla.';
if(is_page($page_name) && is_user_logged_in()){
get_currentuserinfo();
$user_info = get_userdata($current_user->ID);
if(isset($_POST['zip'])){
update_usermeta( $current_user->ID, $key, $_POST['zip'] );
$content .= $success;
} else{
$zip = $user_info->$key;
$content .= '<form method="post"><input type="text" name="zip" value="'.$zip.'" /><input type="submit" value="Update" /></form>';
}
}
return $content;
}
add_filter('the_content', 'pypy_add_form');
