Wordpress/WooCommerce Registration - wordpress

Question

I'm using a plugin (User Profiles Made Easy) that allows a user to choose their own role when registering on my website. It does a good job with that, but what it doesn't do is allow me to conditionally show/hide other fields based on the role they choose.
I thought of Gravity Form and their User Registration add-on, but it won't allow the user to choose their own role when registering.
The WooCommerce tie-in is this: When the buyer checks out, I could collect the extra data at that time (instead of during registration), but I would want to only show the fields relevant to their chosen role. Any ideas?

Borrowing from my tutorial on cutomizing WooCommerce checkout I think we can just wrap certain fields role/capability conditional logica via current_user_can().
// Add a new checkout field
function kia_filter_checkout_fields($fields){
if( current_user_can('some_capability' ) ){
$fields['extra_fields'] = array(
'some_field' => array(
'type' => 'text',
'required' => true,
'label' => __( 'Some field' )
)
);
}
return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'kia_filter_checkout_fields' );
// display the extra field on the checkout form
function kia_extra_checkout_fields(){
if( current_user_can('some_capability' ) ){
$checkout = WC()->checkout(); ?>
<div class="extra-fields">
<h3><?php _e( 'Additional Fields' ); ?></h3>
<?php foreach ( $checkout->checkout_fields['extra_fields'] as $key => $field ) : ?>
<?php woocommerce_form_field( $key, $field, $checkout->get_value( $key ) ); ?>
<?php endforeach; ?>
<?php } ?>
</div>
<?php }
add_action( 'woocommerce_checkout_after_customer_details' ,'kia_extra_checkout_fields' );
// save the extra field when checkout is processed
function kia_save_extra_checkout_fields( $order_id, $posted ){
if( current_user_can( 'some_capability' && isset( $posted['some_field'] ) ) {
update_post_meta( $order_id, '_some_field', sanitize_text_field( $posted['some_field'] ) );
}
}
add_action( 'woocommerce_checkout_update_order_meta', 'kia_save_extra_checkout_fields', 10, 2 );
// display the extra data on order recieved page and my-account order review
function kia_display_order_data( $order_id ){
if( current_user_can('some_capability' ) ){
?>
<h2><?php _e( 'Additional Info' ); ?></h2>
<table class="shop_table shop_table_responsive additional_info">
<tbody>
<tr>
<th><?php _e( 'Some Field:' ); ?></th>
<td data-title="Telephone"><?php echo get_post_meta( $order_id, '_some_field', true ); ?></td>
</tr>
</tbody>
</table>
<?php }
}
add_action( 'woocommerce_thankyou', 'kia_display_order_data', 20 );
add_action( 'woocommerce_view_order', 'kia_display_order_data', 20 );
// display the extra data in the order admin panel
function kia_display_order_data_in_admin( $order ){
if( current_user_can('some_capability' ) ){
?>
<div class="order_data_column">
<h4><?php _e( 'Extra Details', 'woocommerce' ); ?></h4>
<?php
echo '<p><strong>' . __( 'Some field' ) . ':</strong>' . get_post_meta( $order->id, '_some_field', true ) . '</p>'; ?>
</div>
<?php }
}
add_action( 'woocommerce_admin_order_data_after_order_details', 'kia_display_order_data_in_admin' );
