Custom fields not updating

Hello @norbertk

There are errors in the gist code. For example an error on saving occurs here:

$submitted = array_map( 'sanitize_text_field', $_POST[$name] );

PHP Fatal error: Uncaught TypeError: array_map(): Argument #2 ($array) must be of type array, string given

I recommend you to enable debug logging if you write a custom code. Seeing errors in the log helps a lot.

Do you want to add the Mobile Number (mobile_number) field to the first tab Account? Use a solution described in this article: How to display pre-defined fields in Account

You can use a free extension Ultimate Member – Account tabs to display more fields in Account. This extension can create custom account tabs and can embed a profile form into the custom account tab.
