parsing form data into a mailer

[Litninfingers63]

I'm unsure about how I can send mail to multiple form inputs. I have a set up like this:

http://eric.serverselect.net/form.html

I want the users to be able to input a name and e-mail in each box, and have it mail to each e-mail put in, using a loop.

I can do this easily with one person, or pulling information from a database, but i'm not sure about how I can send mail to each person. if I loop the form won't each variable input just overwrite the previous? Any help or tuts to read up on? Thanks so much

unless you use some kind of wierd javascript funtionality to submit all forms (or get more complex to send just the email ones), I sugest you encapsulate all the boxes in one form (as they are being send at the same time anyway.) I spent a few minutes and wrote an example to illustrate:

$keysearch = "email_"; //we'll single out the email_* input names.
$subject = "Your Global Subject";
$from = "[e-mail]";
$message = "Possibly you have a global message too??";

if (isset($_POST['Submit'])) {
	foreach ($_POST as $postkey => $email) {
		if (substr($postkey, 0, strlen($keysearch)) == $keysearch) {
			$number = substr(strrchr($postkey, "_"), 1);
			$to = "{$_POST['name_'.$number]} <$email>";
			send_mail($to, $from, $subject, $message);
		}
	}
}

/*
I find it easier sometimes to encapsulate the 
mail function in my own function in case I want to later 
change the headers, etc. I usually reuse this function 
in a script or group of scripts which means this function 
is typically part of a class or an include file. A bit of 
overkill for this example though ;-)
*/
function send_mail($to, $from, $subject, $message)
{
	$headers =  "From: $from\r\n";
	$headers .= "Reply-To: $from\r\n";	
	mail($to, $subject, $message, $headers);
}

//HTML code below...

<form name="form1" method="post" action="[PHP_TAG]php echo $_SERVER['PHP_SELF'][PHP_CLOSE_TAG]">
  <table width="200" border="0">
    <tr>
      <td width="95">Name</td>
      <td width="95">Email</td>
    </tr>
    <tr>
      <td><input name="name_1" type="text" id="name_1"></td>
      <td><input name="email_1" type="text" id="email_1"></td>
    </tr>
    <tr align="center">
      <td><input name="name_2" type="text" id="name_2"></td>
      <td><input name="email_2" type="text" id="email_2"></td>
    </tr>
    <tr align="center">
      <td><input name="name_3" type="text" id="name_3"></td>
      <td><input name="email_3" type="text" id="email_3"></td>
    </tr>
    <tr align="center">
      <td colspan="2"><input type="submit" name="Submit" value="Submit"></td>
    </tr>
  </table>
</form>

P.S. Don't let the

="[PHP_TAG]php echo $_SERVER['PHP_SELF'][PHP_CLOSE_TAG]">

confuse you, I just put it in so the code highlighting would work properly.
