About php and flash contact form

This is a contact form made in flash and php, it can be used on ‘contact us’ pages.
A flash file contains the form items and when the ’send’ button is pressed it sends the values to mailer.php, this mailer.php sends the email to the receiver.

Few of the benefits of using a flash form instead of a html contact form are:
better user interface
less junk messages (automated scripts cannot send emails through a flash form unless it is decompiled)
Usage details

Upload mailer.php and form.swf on your server in same directory.
In mailer.php you will have to replace ‘email@yourserver.com’ with your email address. Make sure this is an email hosted on that server where you are testing (most server requires this).
Preview

This is a preview of how the contact form looks, you try sending an email to see how form reacts, email will not be sent. It shows a warning if some of the fields are not filled.
