I have created a form in Contact Form 7 and I want the user to be able to submit the form only if the email is found in the database. The database now being used is the Contact Form 7 DB plugin. The list will be preloaded with all the email addresses.
Basically I need someone with Wordpress experience and know how to do a validation hook to the CF7. I will provide all the necessary login details once bidding is successful. The project need to complete in 3 days.
