Update user meta after woocommerce checkout form process - wordpress

Question

I am using woocommerce with Wordpress and have added some custom fields to the checkout:
add_action('woocommerce_after_order_notes', 'my_custom_checkout_field');
function my_custom_checkout_field( $checkout ) {
$extra_fields = array('job_title', 'company', 'telephone', 'occupation');
foreach($extra_fields as $key => $value) {
woocommerce_form_field($value, array(
'type' => 'text',
'class' => array('my-field-class form-row-wide'),
'label' => __($label),
'value' => '',
), $checkout->get_value( $value ));
}
}
Now currently, these appear in the checkout fine, not sure if using woocommerce_after_order_notes is right in this case. I have also added some custom fields to the user meta that correspond to the fields added to the checkout - which all display in the user profile page:
function add_contact_methods( $contactmethods ) {
$contactmethods['job_title'] = 'Job Title';
$contactmethods['company'] = 'Company Name';
$contactmethods['telephone'] = 'Telephone';
$contactmethods['occupation'] = 'Occupation';
$contactmethods['refer'] = 'How you heard about us?';
return $contactmethods;
}
add_filter('user_contactmethods','add_contact_methods',10,1);
As you can imagine, if I update any of these field in any profile page, it works fine but what I cant seem to do is update the user meta when a new user makes a purchase, it does not update the user meta for these fields in the database.
I understand alot of how this works, and understand that I must hook into a Woocommerce process to add the fields into the process. So I have added this code into my functions too:
add_action('woocommerce_checkout_update_user_meta', 'my_custom_checkout_field_update_user_meta');
function my_custom_checkout_field_update_user_meta( $user_id ) {
global $extra_fields;
foreach($extra_fields as $key => $value) {
if ($_POST[$value]) update_user_meta( $user_id, $value, esc_attr($_POST[$value]));
}
}
Now the twist is, this works if a user who is already signed in as a member, makes a repurchase and goes through the checkout - the reason this works is because $user_id already exists, but when a new user is checking out, they do not yet exist as a user, hence the function cannot update the user meta of NIL where $user_id does not exist.
My question is, how do I hook into the checkout process, presumably AFTER the user has been created, so I that I can get the $user_id returned, and execute this function to update the user meta.

Answer 1

class-wc-checkout.php line 639 creates the new user with $this->customer_id = wp_insert_user( apply_filters( 'woocommerce_new_customer_data', $new_customer_data ) ); The new customer data is an array listed just above that line.
Following that, you can access the user id with line 649's action do_action( 'woocommerce_created_customer', $this->customer_id );
It is unlikey, in your case, you will need to use the filter, but simply add the action 'woocommerce_created_customer', pull in the id, and add the meta.

Answer 2

When customer is not logged in checkout page should be acceptable field customer want to create a new account.Below sample code change in checkout page when customer order a new item and update user meta data.
function user_extra_meta_fields(){
return array(
'job_title' => __( 'Job Title', 'yourtext_domain'),
'company' => __( 'Company Name', 'yourtext_domain'),
'telephone' => __( 'Telephone', 'yourtext_domain'),
'occupation' => __( 'Occupation', 'yourtext_domain'),
'refer' => __( 'How you heard about us?', 'yourtext_domain'),
);
}
function add_contact_methods( $contactmethods ) {
$contactmethods = array_merge( $contactmethods, user_extra_meta_fields());
return $contactmethods;
}
add_filter('user_contactmethods','add_contact_methods',10,1);
add_action('woocommerce_after_order_notes', 'my_custom_checkout_field');
function my_custom_checkout_field( $checkout ) {
foreach( user_extra_meta_fields() as $name => $label) {
$value = '';
if( is_user_logged_in() )
$value = get_user_meta( get_current_user_id(), $name, true );
woocommerce_form_field( $name, array(
'type' => 'text',
'class' => array('my-field-class form-row-wide'),
'label' => $label,
), $value );
}
}
add_action( 'woocommerce_checkout_process', 'user_fields_woocommerce_checkout_process' );
function user_fields_woocommerce_checkout_process(){
if( is_user_logged_in() )
add_action('woocommerce_checkout_update_user_meta', 'my_custom_checkout_field_update_user_meta' );
else
add_action( 'woocommerce_created_customer', 'my_custom_checkout_field_update_user_meta' );
}
function my_custom_checkout_field_update_user_meta( $user_id ) {
foreach( array_keys( user_extra_meta_fields() ) as $meta_name ){
if( isset( $_POST[$meta_name] ) ){
$meta_value = $_POST[$meta_name] ? esc_attr($_POST[$meta_name]) : '';
update_user_meta( $user_id, $meta_name, $meta_value );
}
}
}
// if want to validate field
add_action( 'woocommerce_after_checkout_validation', 'user_fields_woocommerce_after_checkout_validation' );
function user_fields_woocommerce_after_checkout_validation( $posted ){
$validate = true;
if( ! is_user_logged_in() && empty( $posted['createaccount'] ) )
$validate = false;
if( $validate == false )
return;
$meta_data = user_extra_meta_fields();
foreach( array_keys( $meta_data ) as $meta_name ){
if( empty($_POST[$meta_name]) )
wc_add_notice( sprintf( __(' <strong>%s</strong> is required.', 'yourtext_domain'), $meta_data[$meta_name] ), 'error' );
}
}
