}
?>

Above is my code plz help me to overcome my problem since i have hosted in the site, it works well in my local server but not working in the website

回答1:

I guess thee is problem with your code at window.location = "contact.html" part. If you want to redirect to this page, try giving absolute path. You may also try window.location.href or window.open. Note that window.open will open it in new window.

回答2:

You also have a very common error a lot of people have with "Contact Us" forms.

// Mail of sender
$mail_from="$customer_mail";

This will break SPF and also cause DMARC to fail and you will never get the message from some people, if your mail server you use has DMARC enabled on it.

Since DMARC is a more recent protocol, a lot of the old cookie cutter code for contact us forms - doesn't take this into account.

You can read more about that here: "DMARC - Contact Form Nightmare"

The suggested workaround will be to do:

$mail_from='it@reverseinformatics.com';
$subject ="$subject" .  $_POST['customer_mail'];

This way - you avoid the issue outline in the article. You won't quickly be able to hit the "Reply" button, but at least you'll get the emails from those customers who have DMARC enabled.
