Question

如何更新 Woocommerce (Wordpress) 中的优惠券代码对象。

$beforeadduseremail="<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="7400110700341319151d185a171b19" rel="noreferrer noopener nofollow">[email protected]</a>";

update_post_meta( 21, 'email_restrictions', $beforeadduseremail);

Answer 1

可以通过不同的方式完成:

在 customer_email 元键上使用 WordPress get_post_meta() 和 update_post_meta():

$coupon_post_id = 21; // The post ID
$user_email     = '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="eb9f8e989fab8c868a8287c5888486" rel="noreferrer noopener nofollow">[email protected]</a>'; // The email to be added

// Get existing email restrictions
$email_restrictions = (array) get_post_meta( $coupon_post_id, 'customer_email', true );

// Add the new email to existing emails
if ( ! in_array( $user_email, $email_restrictions ) ) {
    $email_restrictions[] = $user_email;
}

// Set a back updated email restrictions array
update_post_meta( $coupon_post_id, 'customer_email', $email_restrictions );

使用CRUD methods在 WC_Coupon 对象实例上(自 WooCommerce 3 起):

$coupon_code = 'happysummer'; // The coupon code
$user_email  = '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="7501100601351218141c195b161a18" rel="noreferrer noopener nofollow">[email protected]</a>'; // The email to be added

    // Get an instance of the WC_Coupon object
    $coupon = new WC_Coupon( $coupon_code );

    // Get email restrictions
    $email_restrictions = (array) $coupon->get_email_restrictions();

    // Add the customer email to the restrictions array
    $email_restrictions[] = $customer_email;

    // set the new array of email restrictions
    $coupon->set_email_restrictions( $email_restrictions );

    // Save the coupon data
    $coupon->save();
