Hello,

Thank you very much, this is working like I wanted. I only changed the line:

‘key’ => ‘my_number’,

To:

‘key’ => $field,

So i only need to change the fieldname once.

Hello,

Thank you for the reply. What mean is there are validation options in your great plugin. Like if x exist show y message.

But what I am missing an validation when the same value already has been used on a another post of the same field type.

Let’s say we have a field with an ean number that need to be unique in wordpress. At the moment this is not possible. (So far I know in a relative simple way)
