Hi, In a customer portal I am using frontend-editing of user data.
So, after correct login, the user can change their customer data.
Next to other fields email is also editable.
I am trying to check 2 email fields (one without saving) against each other in a customer portal (...equals to another field).
I am using HTML5-Email fields. But it's not working. Even the email are similar it throws an error message.
What could be the reason?
In addition, is it possible to check for already existing emails in the DB during UPDATING user (meta) data to avoid doubling emails?
If you use the default field user_email, it has the default validation of WordPress to check if the email exists. If you want to check the email value of another custom field, please try to use the remote setting of Validation. Refer to this topic https://support.metabox.io/topic/remote-validation-example/
