Create customer from WooCommerce to MailRelay

The “First Name” field is created in functions.php, in child theme, in localhost for test. The WooCommerce form to create a new customer does not have a “First Name” field by default.

// create field
function wooc_extra_register_fields() {?>
	<p class="form-row form-row-wide">
		<label for="reg_first_name"><?php _e( 'First name', 'woocommerce' ); ?><span class="required">*</span></label>
		<input type="text" class="input-text" name="first_name" id="reg_first_name" value="<?php if ( ! empty( $_POST['first_name'] ) ) esc_attr_e( $_POST['first_name'] ); ?>" />
	</p>
	<div class="clear"></div>
<?php
}
add_action( 'woocommerce_register_form_start', 'wooc_extra_register_fields' );

// validate and save field in WooCommerce/Wordpress

function wooc_validate_extra_register_fields( $username, $email, $validation_errors ) {
    if ( isset( $_POST['first_name'] ) && empty( $_POST['first_name'] ) ) {
        $validation_errors->add( 'first_name_error', __( 'Por favor, introduce tu nombre.', 'woocommerce' ) );
    }
    return $validation_errors;
}
add_action( 'woocommerce_register_post', 'wooc_validate_extra_register_fields', 10, 3 );

function wooc_save_extra_register_fields( $customer_id ) {
    if ( isset( $_POST['first_name'] ) ) {
        update_user_meta( $customer_id, 'billing_first_name', wc_clean( $_POST['first_name'] ) );
        //update_user_meta( $customer_id, 'first_name', sanitize_text_field( $_POST['first_name'] ) );
        // Guardar en WordPress (nombre estándar)
        $user_data = array(
            'ID'         => $customer_id,
            'first_name' => sanitize_text_field( $_POST['first_name'] ),
        );
        wp_update_user( $user_data );
    }
}
add_action( 'woocommerce_created_customer', 'wooc_save_extra_register_fields' );

With code above, a new field is created in WooCommerce account page, register new customer section. The value entered in the field is saved as the First Name, both in the WooCommerce customer data and in the First Name of the WordPress user data.

In the Bit Integrations Field Map drop-down, the First Name field can be selected. I have tested Email (works) and Nickname (works). But if I select First Name, nothing appears in subscriber name in MailRelay platform.

Thanks for your help.

I don’t understand some things…

To resolve this, you need to update your code to include the first name when creating the customer.

Doesn’t this code already include the first name when creating the customer?

<p class="form-row form-row-wide">
		<label for="reg_first_name"><?php _e( 'First name', 'woocommerce' ); ?><span class="required">*</span></label>
		<input type="text" class="input-text" name="first_name" id="reg_first_name" value="<?php if ( ! empty( $_POST['first_name'] ) ) esc_attr_e( $_POST['first_name'] ); ?>" />
</p>

How could I update my code to include the first name when creating the customer?

Please note that whenever a user is created, the data will be sent to MailRelay

If a user is created with a form where the first name field alredy exists (my code provides a “first name” field on the customer creation form), shouldn’t the value of that field be sent to MailRelay, regardless of whether it is updated or not?

Thank you for your attention.

I think is a good idea use the trigger “customer-edit”. I will test it.
Many thanks.

Anyway, how could the First Name in the Bit Integrations Field Map drop-down be used in WooCommerce default registration form?

yes, it is the same field mapping process, but the default woocommerce form only has email and password fields…
