Hello,

I have a form that allows the user to enter one e-mail then it validates it. All is working ok, but now I would like to allow the user to enter more than one e-mail in the form. Wondering if anyone has any tips to help me achive this process in php. I guess I can have user seperate e-mails by a comma, but how do I seperate them for verification? Here is part of my code below.

In the form page:

<form name="forward" method="post" action="email.php">
<input type="text" name="email">
</form>

In the email.php page:

$email = ($_POST['email']);

//Validation

if(!ereg("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,
3})$", $email)) {
                  echo "Invalid E-mail";
}
else .........

Any help would be appreciated. Thanks.

here is the whole script so you dont mess up:

<form name="forward" method="post" action="email.php">
<input type="text" name="emails[]">
<input type="text" name="emails[]">
<input type="text" name="emails[]">
<input type="text" name="emails[]">
<input type="submit">
</form>


---email.php---
$emails = ($_POST['emails']);


foreach($emails as $email) {
    if(!ereg("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)) {
                     echo "Invalid E-mail";
     }
    else {
      echo $email . ' is a valid email<br>';
    }
}
?>

$email_arr = explode(',', $_POST['emails']); // split different emails

and now - validate each from $email_arr[0] to $email_arr[count($email_arr)]

hmm, ok thanks for tha answer mauru, but that code has four input boxes. I would just like one input box for e-mail on my form with the ability to seperate e-mails with a space or a comma. I seem to have it to work and the explode argument helps me split the e-mails up into an array, but how do I validate each e-mail in the array. I see where you are heading Ivanov G, but not totally sure how to implement that.

Something like this:

$email_arr = explode(',', $_POST['emails']); // split different emails

for ($i=0; $i<count($email_arr); $i++)
{
  $current = $email_arr[$i]; // get a email to validate
  if (!ereg("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,5})", $current))
  {
    // invalid email, decide what to do
  }
}

thanks guys. For some reason when I use the explode function to seperate the e-mails with a comma, it doesn't work. But if I seperate it with a space, it works just fine. weird huh?
