Hi,
I am using a Laise module to create contact us page. I am in a need to carry check on entered field before a FORM is sent back to me.

Why do I need it?
I am developing a website to sell long distance Voip Calling cards. These cards have a serial number on them and I want to use then to log genuine Email support Queries. This way I would also rectify unwanted support Emails.

I have added field (12 digit PIN NUMBER ) in contact us form which would be entered by user, How can I check it against one stored in MySQL database before sending it as Email?

Best Regards,
Sagar
