The easiest guess is that you're doing a mistake accessing your variables.
instead of:
$name2=$_POST["$name2"];
use this:
$name2=$_POST["name2"];
Or, if you know the difference and are doing this on purpose, make sure your $name2
variable is defined with the correct name of the HTML form field.
As an aside, I would strongly recommend using a library like PHPMailer to send emails.
Your example is quite simple and the mail() should work just fine, but for anything more elaborate (ie. having attachments or html) or needing to send using an external mail server by SMTP (with or without authentication), it will do a much better job and save you lots of time.
For a better idea, check this example from their website:
require_once('../class.phpmailer.php');
$mail = new PHPMailer(true); // the true param means it will throw exceptions on errors, which we need to catch
$mail->IsSMTP(); // telling the class to use SMTP
try {
$mail->Host = "mail.yourdomain.com"; // SMTP server
$mail->SMTPDebug = 2; // enables SMTP debug information (for testing)
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Host = "mail.yourdomain.com"; // sets the SMTP server
$mail->Port = 26; // set the SMTP port for the GMAIL server
$mail->Username = "yourname@yourdomain"; // SMTP account username
$mail->Password = "yourpassword"; // SMTP account password
$mail->AddReplyTo('[email protected]', 'First Last');
$mail->AddAddress('[email protected]', 'John Doe');
$mail->SetFrom('[email protected]', 'First Last');
$mail->AddReplyTo('[email protected]', 'First Last');
$mail->Subject = 'PHPMailer Test Subject via mail(), advanced';
$mail->AltBody = 'To view the message, please use an HTML compatible email viewer!'; // optional - MsgHTML will create an alternate automatically
$mail->MsgHTML(file_get_contents('contents.html'));
$mail->AddAttachment('images/phpmailer.gif'); // attachment
$mail->AddAttachment('images/phpmailer_mini.gif'); // attachment
$mail->Send();
echo "Message Sent OK<p></p>\n";
} catch (phpmailerException $e) {
echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
echo $e->getMessage(); //Boring error messages from anything else!
}
