I came here from the treehouse site and I have a problem. Everything seems fine but when I click send nothing happens. Nothing at all, no error, no email, just nothing. Any help you be great. Thank you.

Thanks for this Aaron. I can't seem to get a reply to address working with this. Any clues?

Thanks! I'm also using this form via the Treehouse Blog.

But I noticed it will fail for anyone with an @yahoo address because of Yahoo's aggressive anti-spamming DMARC policy change (appears to send, but mail is never received).

Workaround was simple. Just change the "From: " header to your own domain, and put the user's email in a "Reply-to" field. Just change line 35 above to:

// Build the email headers.
$email_headers = "From: Example Webmaster <webmaster@example.com>\r\nReply-To: $name <$email>";

Just a thought, I have a situation where there are more than one contact form on the same page (The page has separate tabbed areas each with a contact form and the form sends specific data dependent on which tabbed area the user is in. The issue I notice with this scenario is that app.js sends back to the div ID #form-messages the success message.

I guess I could send back to a different div ID each time but that doesn't make sense to me. Is there a way of dynamically doing the success message without doing silly things like creating separate app.js files?

Sorry if my questions are newbie but I'm not yet experienced :-)

Thanks!

Thanks!

Thanks a lot

I have a problem. If email have a dot in name (example: steve.steve@mail.com), you didn't get an email to this address, although the script reports successful transmission.

I would also recommend using this php mail library instead:
https://github.com/PHPMailer/PHPMailer

How can a clear the form data for select options
