On two wordpress pages ( like this: [url removed, login to view] ) customers are asked to enter their email so it is entered in a customer database when they buy.
When they click on the "Buy" button bellow, I want to display an alert message saying "The subscription you are buing will be activated for the account (the email they entered), is that valid, yes/no).
If they click on yes they are brought to the Paypal buy page as before, will all the good values of the form transmited (just as before).
Also, I want to check that the email is valid (simple check, that is contains no space, a @, a domain name).
No milestone payment, please check my reviews I'm a good payer :)
