You are trying to get the con_id from $_[POST] but that's not possible since there is no id for the person yet. Of course it will be empty. You need to retrieve the newly created id from the consumer table.

To do this in mysql_ functionality you will need to execute the query BEFORE sending the email, then use mysql_insert_id() to get the id that was inserted when you ran $query

That being said:

Please, don't use mysql_* functions in new code. They are no longer maintained and are officially deprecated. See the red box? Learn about prepared statements instead, and use PDO or MySQLi - this article will help you decide which. If you choose PDO, here is a good tutorial.
