Answer 1

As per my understanding of your question, I have created this snippet which will help you with your requirement.
// add a field on the check payment type
add_filter( 'woocommerce_gateway_description', 'custom_check_payment_field', 10, 2 );
function custom_check_payment_field( $description, $payment_id ) {
if ( is_user_logged_in() ) {
$user = wp_get_current_user();
$current_user_role = (array) $user->roles;
if ( 'cheque' === $payment_id && $current_user_role[0] == 'administrator') {
ob_start();
echo '<div class="cheque-field">';
woocommerce_form_field(
'customer_cheque_number',
array(
'type' => 'text',
'label' => __( 'Enter cheque number', 'woocommerce' ),
'class' => array( 'form-row-wide' ),
'required' => true,
),
''
);
echo '<div>';
$description .= ob_get_clean();
}
}
return $description;
}
// save check number in meta/database
add_action( 'woocommerce_checkout_create_order', 'save_customer_cheque_number_order_meta', 10, 2 );
function save_customer_cheque_number_order_meta( $order, $data ) {
if ( isset( $_POST['customer_cheque_number'] ) && ! empty( $_POST['customer_cheque_number'] ) ) {
$order->update_meta_data( '_customer_cheque_number', esc_attr( $_POST['customer_cheque_number'] ) );
}
}
// show check number on orders page (OPTONAL)
add_action( 'woocommerce_get_order_item_totals', 'display_customer_cheque_number_on_order_totals', 10, 3 );
function display_customer_cheque_number_on_order_totals( $total_rows, $order, $tax_display ) {
if ( $order->get_payment_method() === 'cheque' && $customer_cheque_number = $order->get_meta( '_customer_cheque_number' ) ) {
$sorted_total_rows = array();
foreach ( $total_rows as $key_row => $total_row ) {
$sorted_total_rows[ $key_row ] = $total_row;
if ( $key_row === 'payment_method' ) {
$sorted_total_rows['customer_cheque_number'] = array(
'label' => __( 'Cheque number', 'woocommerce' ),
'value' => esc_html( $customer_cheque_number ),
);
}
}
$total_rows = $sorted_total_rows;
}
return $total_rows;
}
// add meta box on orders on woocommerce backend
add_action( 'add_meta_boxes', 'add_meta_boxes_callback' );
if ( ! function_exists( 'add_meta_boxes_callback' ) ) {
function add_meta_boxes_callback() {
add_meta_box( 'shop_order_fields', __( 'Cheque number', 'woocommerce' ), 'orders_cheque_number_custom_meta', 'shop_order', 'side', 'core' );
}
}
// show meta field with entered check number
if ( ! function_exists( 'orders_cheque_number_custom_meta' ) ) {
function orders_cheque_number_custom_meta() {
global $post;
$check_number = get_post_meta( $post->ID, '_customer_cheque_number', true ) ? get_post_meta( $post->ID, '_customer_cheque_number', true ) : '';
?>
<input type="text" style="width:250px;margin-top:15px" readonly name="readonly_check_number" value="<?php echo $check_number; ?>"></p>
<?php
}
}
