function wp_change_namecar( $atts, $content = null ) {
if (is_user_logged_in()) {
$user_id = get_current_user_id();
$userval = //how to define that it is the value of the form?
if (isset($_POST[\'validate_user\'])) {
if ($_POST[\'validate_user\'] == $user_id) {
if (update_user_meta( $user_id, \'user_name_car\', \'$userval\' )) {
return "<div class=\'user_updated\'>Updated!</div>";
} else {
return "<div class=\'user_updated error\'>Not Updated!</div>";
}
}
}
//Show the form
