 * Hi all!
    I am using the plugin _User Profiles Made Easy_ and I have created a
   custom field. Now I don’t know if this custom field created can be visualized
   in the database or not, but what I want to do is to put some PHP function inside
   the custom field that checks if the number input by the user in the custom field
   exists in the database. Can someone guide me on how to do this? How can I and
   where do I put this custom code, modifying at the end the plugin.
