Execute only on filled out inputs

[signature16]

I am trying to create a little "refer a friend" thing to put on a website.  There are six text boxes where a visitor can type in different emails.  When the visitors submits, I want a default email to go out to the emails given.

 

How can I set it up so that 3 mail() commands are executed if 3 emails are entered.... or 6 mail() commands if 6 emails are entered? 

 

Does that make sense?

instead of keeping six text boxes for different emails you can keep one text box and an instruction to visitor to enter all the email ad/s in that box separated by comma. this will help you !

This is how I have mine

 

The form I use uses a drop down menu, so this is it:

<select name="person[]" multiple size="10">

 

 

To send the mail according to how may were selected.

$to=$_POST['person'];

$together = implode(", ", $to);
for($i = 0; $i < count($to); $i++){
//mail the user
    $subject = "Refer";
    $message = "	

$_POST[message]

===================================
This is an automated email and unchecked account, please do not reply this email!";  
}

     mail($together, $subject, $message, 
        "From: NO REPLY<[email protected]/>\n");

 

 

Hope this helps
