Answer 1

Found a solution in the open spaces. Implemented it seems to work well!
## --- FOR CHECKOUT --- ##
// Checkout billing phone validation (Checking length)
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');
function my_custom_checkout_field_process() {
if ( $_POST['billing_phone'] && strlen($_POST['billing_phone']) < 10 )
wc_add_notice( __('Please type a correct phone number…', 'woocommerce'), 'error' );
}
## --- FOR CUSTOM REGISTRATION FORM --- ##
// Add custom fields to registration form.
add_action('woocommerce_register_form_start', 'text_domain_woo_reg_form_fields');
<?php _e('First name', 'woocommerce'); ?>*
<?php _e('Last name', 'woocommerce'); ?>*
<?php _e( 'Phone', 'woocommerce' ); ?>
*
<?php
}
// Checking & validation of custom fields in registration form.
add_action('woocommerce_register_post', 'text_domain_woo_validate_reg_form_fields', 10, 3);
function text_domain_woo_validate_reg_form_fields( $username, $email, $validation_errors ) {
if (isset($_POST['billing_first_name']) && empty($_POST['billing_first_name'])) {
$validation_errors->add('billing_first_name_error', __( 'İsim alanı zorunludur! / Name field is required!', 'woocommerce'));
$validation_errors->add('billing_last_name_error', __('Soyisim alanı zorunludur! / Surname field is required!', 'woocommerce'));
}
if (isset($_POST['billing_phone']) && empty($_POST['billing_phone'])) {
$validation_errors->add('billing_phone_error', __('Telefon alanı zorunludur! / Phone field is required!' , 'woocommerce'));
}
// ==> CHECKING PHONE LENGTH (10 character minimal) <==
if (isset($_POST['billing_phone']) && strlen($_POST['billing_phone']) < 10 ) {
$validation_errors->add( 'billing_phone_error', __('Please type a correct phone number…', 'woocommerce'));
}
return $validation_errors;
add_action( 'woocommerce_created_customer', 'custom_save_extra_register_fields' ); // <==== Missing
function custom_save_extra_register_fields($customer_id) {
//First name field
if (isset($_POST['billing_first_name'])) {
update_user_meta($customer_id, 'first_name', sanitize_text_field($_POST['billing_first_name ']));
update_user_meta($customer_id, 'billing_first_name', sanitize_text_field($_POST['billing_first_name']));
}
//Last name field
if (isset($_POST['billing_last_name'])) {
update_user_meta($customer_id, 'last_name', sanitize_text_field($_POST['billing_last_name']));
update_user_meta($customer_id, 'billing_last_name', sanitize_text_field($_POST['billing_last_name']));
}
//Phone field
if (isset($_POST['billing_phone'])) {
update_user_meta($customer_id, 'phone', sanitize_text_field($_POST['billing_phone']));
update_user_meta($customer_id, 'billing_phone', sanitize_text_field($_POST['billing_phone']));
}
}
