# Validation Hook for custom Forms possible?

 * Hello,
 * I am currently looking into buying the Plugin. I would love to add a “voucher
   code” field for the user to enter when trying to make a reservation. Then I want
   to validate this code with some sort of SQL-Statement against the database. Is
   something like this possible in any way? I am able to code but do not want to
   change the plugin itself to add these kinds of features. Perhaps there is a way
   I can use a hook for this kind of validation?
 * Best regards
    Manuel

 * You can apply your changes in the plugin.
    There is no hook for this kind of 
   validation at the moment.
 * Thank you.
