There will almost certainly be times when you want to request for an email address to be entered on one of your forms. There is no easy way to validate that the email address that is entered actually exists and certainly no way to validate that it belongs to the person that entered it but we can at least validate that the email address is in an acceptable format that is recognisable as an email address.
Next we'll look at a working example that demonstrates how this script handles the various different values that might be entered into an email address field so that you can see for yourself how it works.
Note that the script and the description of how to use it are copied from the Ask Felgall website with the permission of the copyright owner.
