Why is data update and redirect not working?

Question

WordPress

Hello. I wrote an HTML form + an input handler in PHP and for some reason this whole construction does not work. User data is not updated, and after clicking on the "Send" button, only the header is displayed, although the page is loaded with exactly the same address, that is: localhost/profile/?user=4, where the value of the user variable is the id of the owner of the personal account, which we consider. In this case, ours, because we are changing the data. I would be extremely grateful for your help.

<div id="edit" class="edit tab-pane fade" role="tabpanel">
                        <?php do_action( 'cgc_process_user_profile' ); ?>
                        <form method="POST">
                            <?php wp_nonce_field('user_profile_nonce', 'user_profile_nonce_field'); ?>

Функция определена, но нигде не вызывается. После определения функции надо добавить:

add_action( 'init', 'cgc_process_user_profile_data' );
