Get ACF custom fields values in woocommerce custom email notification

问题

If the user Woocommerce changes his data, a mail to the administrator receives a email about these changes.

I need to show in this letter the custom fields that I created in the ACF. (In ACF created a questionnaire and put it into a /edit-account)

Here is the complete code, based on - Send notification email when customer changes address WooCommerce

if( !class_exists('WooCommerceNotifyChanges') ){

class WooCommerceNotifyChanges{

function __construct(){
    // customer saves main account data
    add_action('woocommerce_save_account_details', array( $this, 'woocommerce_send_notification' ));
}

function woocommerce_send_notification(){
    $body       = '';
    $to         = 'email@domain.com';    //address that will receive this email
    $subject    = 'One of your customers has updated their information.';

    $curr_user      = wp_get_current_user();
    $user_id        = $curr_user->ID;
    $curr_username  = $curr_user->data->user_login;

    $body .= '<table>';
    $body .= '<tr><td><strong>Account</strong></td></tr>';
    $body .= '<tr><td>Username: </td><td>' . $curr_username                                         . '</td></tr>';
    $body .= '<tr><td>First name: </td><td>' . get_user_meta( $user_id, 'billing_first_name', true ). '</td></tr>';
    $body .= '<tr><td>Last name: </td><td>' . get_user_meta( $user_id, 'billing_last_name', true )  . '</td></tr>';
    $body .= '<tr><td>Phone: </td><td>' . get_field('user_phone') . '</td></tr>';
    $body .= '<tr><td>Age: </td><td>' . get_field('user_age') . '</td></tr>';
    $body .= '</table>';    

    //set content type as HTML
    $headers = array('Content-Type: text/html; charset=UTF-8;');

}
} new WooCommerceNotifyChanges(); 
} 

Unfortunately, the custom field is not displayed. All fields in my account have been filled in, I received a email about changing the user's data. But custom fields are not shown in the email.

I tried the option:

$body .= '<tr><td>Phone: </td><td>' . get_field('user_phone', 'user_1') . '</td></tr>';
$body .= '<tr><td>Phone: </td><td>' . get_field('user_phone', $user_id) . '</td></tr>';

I will be happy with your help.

First, you can't use logically wp_get_current_user() for email notifications or backend orders, as there is no a current user anymore.

But if you have a look to woocommerce_save_account_details hook source code you will notice that $user_id is passed as a hook argument and you can use it in the related function, as following:

if( !class_exists('WooCommerceNotifyChanges') ){
    class WooCommerceNotifyChanges{

        function __construct(){
            // customer saves main account data
            add_action('woocommerce_save_account_details', array( $this, 'woocommerce_send_notification' ), 15, 1 );
        }

        function woocommerce_send_notification( $user_id ){
            $body      = '';
            $to        = 'email@domain.com';    //address that will receive this email
            $subject   = 'One of your customers has updated their information.';

            $user      = new WP_User( $user_id );
            $user_name = $user->user_login;

            $body .= '<table>';
            $body .= '<tr><td><strong>' . __("Account") . '</strong></td></tr>';
            $body .= '<tr><td>Username: </td><td>' . $user_name                                         . '</td></tr>';
            $body .= '<tr><td>First name: </td><td>' . $user->billing_first_name . '</td></tr>';
            $body .= '<tr><td>Last name: </td><td>' . $user->billing_last_name  . '</td></tr>';
            $body .= '<tr><td>Phone: </td><td>' . get_field( 'user_phone', $user_id ) . '</td></tr>';
            $body .= '<tr><td>Age: </td><td>' . get_field( 'user_age', $user_id ) . '</td></tr>';
            $body .= '</table>';    

            //set content type as HTML
            $headers = array('Content-Type: text/html; charset=UTF-8;');
        }
    } 
    new WooCommerceNotifyChanges(); 
} 

Now it should work.

To get fields from a user record in ACF you don't just pass the user's ID, you have to pass it in a string prepended with "user_", so the string should be: "user_{$user_id}" and the whole thing would therefore be get_field( 'user_age', "user_{$user_id}" )

See the docs: https://www.advancedcustomfields.com/resources/how-to-get-values-from-a-user/
