Is anyone can help me to place a validation in myaccount while updating customized fields

to view&update custom fields in the [ultimatemember_account] page, this is some distilled code from here, to be added to your theme's functions.php:

add_action('um_after_account_general', 'showUMExtraFields', 100);

function showUMExtraFields() {
  $id = um_user('ID');
  $output = '';
  $names = array('phone_number', 'company');

  $fields = array(); 
  foreach( $names as $name )
    $fields[ $name ] = UM()->builtin()->get_specific_field( $name );
  $fields = apply_filters('um_account_secure_fields', $fields, $id);
  foreach( $fields as $key => $data )
    $output .= UM()->fields()->edit_field( $key, $data );

  echo $output;
}

add_action('um_account_pre_update_profile', 'getUMFormData', 100);

function getUMFormData(){
  $id = um_user('ID');
  $names = array('phone_number', 'company');

  foreach( $names as $name )
    update_user_meta( $id, $name, $_POST[$name] );
}

tested with 2.0.13

How would one use this code to display the custom fields after another specific field (such as after the Username field in the Account tab), as well as make the custom fields uneditable? (Similar to the Username field in the account tab)

This one works good, thanks!

Hello
I don't know if this is the right tutorial for displaying custom fields.
My problem is that when I want to display the predefined field "user_mail", it displays nothing. I don't have an email address, as you know, you need one to register, but it works.
How do I display it?
