Well, I'm preparing for my website, I've no experience about PHP but I had to do my website using PHP, anyway, I've a contact form which I've put a check box in the end of it's form asking the sender if he wants to send a copy of the message to his email entered in a field in this form.
How can I make it work to send him a copy when he check the box and not to send him anything when he didn't check the box?
