Hi
I don't know if it possible to do this but what I want to achieve is to set a field so that it checks to ensure the value that has been entered is unique.

Currently what is happening is that an individual is creating a user account, a couple of months later they forget and then create a new account using a different username and email.

One of the fields on their profile page that they are required to complete is their Identification number, what I want to achieve is that if they have a profile and then create a new one the system picks up that they already have an account and then prompts them to contact us for assistance.

Hi,
sorry for late reply, unfortunately this is not possible natively and there is not a simple way to make this.

Complex alternative is to develop a user plugin that check this and does not allow registration when the value is not unique. To do this you need Joomla Dev and PHP knowledges.

Hi

I for anyone who wants to achieve this I found a solution that seems to work.
Once you have created the Field that you want so set to accept unique values only go into your database and find the jsn_users table select structure and then set the field to unique.
The result is that an individual will not be able to save their profile info if the field does not contain unique data.

Now the only thing I still need to figure out is how to display an error message.
