Add a custom field to checkout and to my_account user details on registration

Question

I have a woocommerce site I am building and I want to add the user's birthdate to the usermeta in the database as well as display it in the wp-admin under their profile.

I have limited experience with messing with PHP.

I have pulled from the Woocommerce docs here to display it on checkout, which it is doing correctly.

The Woocommerce docs show you how to add it to the order info but not to the user account itself. It is correctly being added to the order but not the account.

Here is what I have so far:

/**
 * Add the field to the checkout
 */
add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );

function my_custom_checkout_field( $checkout ) {

    echo '<div id="my_custom_checkout_field">';

    woocommerce_form_field( 'birthdate', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Date of Birth'),
        'placeholder'   => __('mm/dd/yyyy'),
        ), $checkout->get_value( 'birthdate' ));

    echo '</div>';

}

/**
 * Process the checkout
 */
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {
    // Check if set, if its not set add an error.
    if ( ! $_POST['birthdate'] )
        wc_add_notice( __( 'Please enter your date of birth.' ), 'error' );
}

/**
 * update order meta with field value
 */

add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta' );


function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ( ! empty( $_POST['birthdate'] ) ) {
        update_post_meta( $order_id, 'Birthdate', sanitize_text_field( $_POST['birthdate'] ) );
    }
}

/**
 * update user meta with birthdate
 */

add_action ( 'personal_options_update', 'my_save_extra_profile_fields' );
add_action ( 'edit_user_profile_update', 'my_save_extra_profile_fields' );

function my_save_extra_profile_fields( $user_id )
{
    if ( ! empty( $_POST['birthdate'] ) ) {
        update_usermeta( $user_id, 'Birthdate', sanitize_text_field( $_POST['birthdate'] ) );
    }
}


/**
 * Display field value on the order edit page
 */
add_action( 'woocommerce_admin_order_data_after_billing_address', 'my_custom_checkout_field_display_admin_order_meta', 10, 1 );
add_action ( 'show_user_profile', 'my_custom_checkout_field_display_admin_order_meta' );
add_action ( 'edit_user_profile', 'my_custom_checkout_field_display_admin_order_meta' );

function my_custom_checkout_field_display_admin_order_meta($order){
    echo '<p><strong>'.__('Birthdate').':</strong> ' . get_post_meta( $order->id, 'Birthdate', true ) . '</p>';
}

I am also getting this error on the user info page:

Notice: WP_User->id was called with an argument that is deprecated since 
version 2.1.0! Use WP_User->ID instead. in 
/Applications/MAMP/htdocs/tst_dev/wp-includes/functions.php on line 3891

I have also tried this instead of my version of the user update meta.

add_action( 'user_register', 'my_custom_update_user');

function my_custom_update_user( $user_id )
{        
    if ( $user_id != 0 ) {             // check if user is not a guest
            update_usermeta( $user_id, 'Birthdate', sanitize_text_field( $_POST['birthdate'] ) );
        }
}

1) SOLVING THE ERROR:

You have to use update_user_meta() instead of deprecated update_usermeta() to avoid the error.

2) CLEANING AND CHANGING YOUR CODE:

For custom fields, is better to avoid capitals in the slug.

// Add the field to the checkout
add_action( 'woocommerce_after_order_notes', 'birth_day_checkout_field' );
function birth_day_checkout_field( $checkout ) {

    // if customer is logged in and his birth date is defined
    if(!empty(get_user_meta( get_current_user_id(), 'account_birth_date', true ))){
        $checkout_birht_date = esc_attr(get_user_meta( get_current_user_id(), 'account_birth_date', true ));
    }
    // The customer is not logged in or his birth date is NOT defined
    else {
        $checkout_birht_date = $checkout->get_value( 'birth_date' );
    }

    echo '<div id="my_custom_checkout_field">';

    woocommerce_form_field( 'birth_date', array(
        'type'          => 'text',
        'class'         => array('birth-date form-row-wide'),
        'label'         => __( 'Date of Birth', 'theme_domain_slug' ),
        'placeholder'   => __( 'mm/dd/yyyy', 'theme_domain_slug' ),
        ), $checkout_birht_date);

    echo '</div>';

}


// Process the checkout
add_action('woocommerce_checkout_process', 'birth_day_checkout_field_process');
function birth_day_checkout_field_process() {
    // Check if set, if its not set add an error.
    if ( ! $_POST['birth_date'] )
        wc_add_notice( __( 'Please enter your date of birth.', 'theme_domain_slug' ), 'error' );
}


// update order meta with field value
add_action( 'woocommerce_checkout_update_order_meta', 'birth_day_checkout_field_update_order_meta' );
function birth_day_checkout_field_update_order_meta( $order_id ) {
    if (!empty( $_POST['birth_date'])){
        update_post_meta( $order_id, 'birth_date', sanitize_text_field( $_POST['birth_date'] ) );

        // updating user meta (for customer my account edit details page post data)
        update_user_meta( get_post_meta( $order_id, '_customer_user', true ), 'account_birth_date', sanitize_text_field($_POST['birth_date']) );
    }
}

// update user meta with Birth date (in checkout and my account edit details pages)
add_action ( 'personal_options_update', 'birth_day_save_extra_profile_fields' );
add_action ( 'edit_user_profile_update', 'birth_day_save_extra_profile_fields' );
add_action( 'woocommerce_save_account_details', 'birth_day_save_extra_profile_fields' );
function birth_day_save_extra_profile_fields( $user_id )
{
    // for checkout page post data
    if ( isset($_POST['birth_date']) ) {
        update_user_meta( $user_id, 'account_birth_date', sanitize_text_field($_POST['birth_date']) );
    }
    // for customer my account edit details page post data
    if ( isset($_POST['account_birth_date']) ) {
        update_user_meta( $user_id, 'account_birth_date', sanitize_text_field($_POST['account_birth_date']) );
    }
}

    echo '<p><strong>' . __( 'Birth date:', 'theme_domain_slug' ) . '</strong> ' . get_post_meta( $order->id, 'birth_date', true ) . '</p>';
}

3) ADDING THE FIELD TO CUSTOMER MY ACCOUNT EDIT DETAILS:

You could have used the woocommerce_edit_account_form_start hook to insert this custom field in customer my_account edit details page, but you don't have the control in placement and ordering.

It's better to included it your active theme woocommerce template folder my_account/form-edit-account.php (if you don't have this folder yet, read Overriding Templates via a Theme, to understand how you can do it.

Here the Birth Date custom field with be located on right side of the email address in My account edit account details form.

Here is the code of this customized template:

<?php
/**
 * Edit account form
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/myaccount/form-edit-account.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see     https://docs.woocommerce.com/document/template-structure/
 * @author  WooThemes
 * @package WooCommerce/Templates
 * @version 2.6.0

}

All the code goes in function.php file of your active child theme (or theme) or also in any plugin file, (except for the template code).

This code is tested and works.

Unfortunately this isn't working. I am still getting the same error. Also I had an error about the birth_day_custom_checkout_field_display_admin_order_meta function. I took out the custom because it wasn't in the rest of the code. I have also confirmed no data has updated in the database. – Principium

Can confirm this works now. Thanks for all the help! – Principium

@BrianEdelman Thanks for correcting that little mistake :) (sorry) – Artie

Answer 2

The simplest way to achieve your goal is to update user meta while updating order meta.

/**
 * update order meta with field value
 */

add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta' );


function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ( ! empty( $_POST['birthdate'] ) ) {

        update_post_meta( $order_id, 'Birthdate', sanitize_text_field( $_POST['birthdate'] ) );

        $order = WC_Order( $order_id );    // getting order object
        $user_id = $order->get_user_id();  // getting user id
        if ( $user_id != 0 ) {             // check if user is not a guest
            update_usermeta( $user_id, 'Birthdate', sanitize_text_field( $_POST['birthdate'] ) );
        }
    }
}

You should also delete "update user meta with birthdate" section.
