I have a tell-a-friend PHP script that I'm already using successfully and I want to tweak it so that visitors can optionally send a notice to multiple email addresses.

I've named and added several new fields to the form. Can anyone tell me how to update the script to accomodate this?

Perhaps it would also help if I post the entire script below.

Thanks

<?php
  $tomail = $_POST[\"friend_email\"];

  //THE ADDITIONAL EMAIL FIELDS ARE NAMED
  //friend_2, friend_3, friend_4, friend_5

  $from = $_POST[\"sender_email\"];
  $copyfrom = $_POST[\"sender_email\"];
  $notifyMail = \"[email protected]\";

  // Check the email address
  $replace_str = array (\"&amp;\", \"&gt;\", \"&lt;\", \"&copy;\", \"&nbsp;\",

Just quick suggestion.

Name all the TO fields the same (say sender_email[]

Now you will have an array in PHP, , ex. $_POST['sender_email'][0], $_POST['sender_email'][1], $_POST['sender_email'][2]

Break you code up so it does all the checking of the info that will be the same on every e-mail (sender's e-mail, setting up the actual message and headers, etc). Then do a loop, simliar to the following:

foreach ($_POST['sender_email'] as $thisEmail)
{
    // VALIDATE THE E_MAIL ADDRESS HERE, the current e-mail is in $thisEmail

    // SEND THE E_MAIL HERE
}
'
You will probably want to ad checking on each one to make sure each of them actually validate good.

Just a rough solution for you, normally I'd et more detailed, but kinda tired today.

Your email checking function is a bit too 'messy'. Why would you try and replace invalid characters? If someone enters one, simply throw an error at them and ask them to modify their it.

I would use something like the following regular expression to test email validity (inspired by the book essential PHP security from Chris Shifflet):

if(preg_match('/^[^@\s<&>]+@([-a-z0-9]+\.)+[a-z]{2,}$/i', $thisEmail)){
  //email is ok
}else{
  //email invalid
}
'

A buddy of mine from Indiana resolved this issue in about ten minutes. In case anyone's interested, the below code works perfectly.

Thanks
