Hey guys, here is my code right now for a simple sendmail form. I want to add an addtional field but am having a hell of a time doing it. My 3 required variables work fine, but I can't for the life of me add an additional variable to be sent in the email. All I'm tryign to do is add a telephone number field. you can check out the form here http://www.alertpc.net/dave4/repair-contacts.html

 
<?php
/* All form fields are automatically passed to the PHP script through the array $HTTP_POST_VARS. */
$email = $HTTP_POST_VARS['email'];
$subject = $HTTP_POST_VARS['subject'];
$message = $HTTP_POST_VARS['message'];


/* PHP form validation: the script checks that the Email field contains a valid email address and the Subject field isn't empty. preg_match performs a regular expression match. It's a very powerful PHP function to validate form fields and other strings - see PHP manual for details. */
if (!preg_match("/\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/", $email)) {
  echo "<h4>Invalid email address</h4>";
  echo "<a href='javascript:history.back(1);'>Back</a>";
} elseif ($subject == "") {
  echo "<h4>No subject</h4>";
  echo "<a href='javascript:history.back(1);'>Back</a>";
}
/* Sends the mail and outputs the "Thank you" string if the mail is successfully sent, or the error string otherwise. */
elseif (mail('my email goes here',$subject,$message,$email)) {
  echo "<h4>Thank you for contacting uspair.  Your email has been sent.</h4>";
} else {
  echo "<h4>Can't send email to $email</h4>";
}
?>

Here you go, could you tell me why you thought this is hard to do?

(Just add a telephone field to your form now)

PHP Code:

<?php
/* All form fields are automatically passed to the PHP script through the array $HTTP_POST_VARS. */
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$telephone = $_POST['telephone'];

/* PHP form validation: the script checks that the Email field contains a valid email address and the Subject field isn't empty. preg_match performs a regular expression match. It's a very powerful PHP function to validate form fields and other strings - see PHP manual for details. */
if (!preg_match("/\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/", $email)) {
  echo "<h4>Invalid email address</h4>";
  echo "<a href='javascript:history.back(1);'>Back</a>";
} elseif ($subject == "") {
  echo "<h4>No subject</h4>";
  echo "<a href='javascript:history.back(1);'>Back</a>";
}

if (!empty($telephone)) {
    $message .= "\r\n\r\nTelephone: " . $telephone;
}

/* Sends the mail and outputs the "Thank you" string if the mail is successfully sent, or the error string otherwise. */
elseif (mail('my email goes here',$subject,$message,$email)) {
  echo "<h4>Thank you for contacting uspair.  Your email has been sent.</h4>";
} else {
  echo "<h4>Can't send email to $email</h4>";
}
?>

Can you please explain what exactly this line of code does?

 
if (!empty($telephone)) {
    $message .= "\r\n\r\nTelephone: " . $telephone;
}

As it is right now it doesn't return anythign to my email address. And I recieve no output. If I add this code:

if (!empty($telephone)) {
    $message .= "\r\n\r\nTelephone: " . $telephone;
 echo "<h4>Telephone Error</h4>";
}

it does return "Telephone Error" on the page. I am not an expert by any means, which is why I've come here for guidance.

@EJK - What that is doing is adding in some blank lines and then added the telephone number to the bottom of the message. var_dump the post variable to make sure that the value is actually there.

You shouldn't add the telephone error message there. In fact, I don't think a telephone nr is a required field is it? So there should be no error output, ever. Remove that line.

Anyway, it's my mistake. This should now work: (Simply a case of not having spotted the elseif)

PHP Code:

<?php
/* All form fields are automatically passed to the PHP script through the array $HTTP_POST_VARS. */
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$telephone = $_POST['telephone'];

/* PHP form validation: the script checks that the Email field contains a valid email address and the Subject field isn't empty. preg_match performs a regular expression match. It's a very powerful PHP function to validate form fields and other strings - see PHP manual for details. */
if (!preg_match("/\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/", $email)) {
  echo "<h4>Invalid email address</h4>";
  echo "<a href='javascript:history.back(1);'>Back</a>";
} elseif ($subject == "") {
  echo "<h4>No subject</h4>";
  echo "<a href='javascript:history.back(1);'>Back</a>";
} else {
  if (!empty($telephone)) {
       $message .= "\r\n\r\nTelephone: " . $telephone;
  }
  /* Sends the mail and outputs the "Thank you" string if the mail is successfully sent, or the error string otherwise. */
  if (mail('my email goes here',$subject,$message,$email)) {
    echo "<h4>Thank you for contacting uspair.  Your email has been sent.</h4>";
  } else {
    echo "<h4>Can't send email to $email</h4>";
  }
}
?>

Thank you very much xistins and premium scripts. The reason I put the that extra line of code is to see where it actually stopped since I wasn't getting a return.

I'll be able to take the this bit of code and run with it. I really appreciate all the help you guys have given me!
