help!! I'm stuck on something...

[luchazard]

I have the following form:

<form action="taf.php" method="post>
<input type="text" name="from_email">
<input type="text" name="email_1">
<input type="text" name="email_2">
<input type="text" name="email_3">
<input type="submit" name="submit">
</form>

In the PHP script 'taf.php' I want to make sure that all the email addresses are valid. Please tell me if what I have put down is correct!!

function check_email ($from_email, $email_1, $email_2, $email_3) {

return (ereg('^[-!#$%&\'*+\\./0-9=?A-Z^_`a-z{|}~]+'.'@'.'[-!#$%&\'*+\\/0-9=?A-Z^_`a-z{|}~]+\.'.'[-!#$%&\'*+\\./0-9=?A-Z^_`a-z{|}~]+$',$from_email, $email_1, $email_2, $email_3));

}

if ($submit) {

if (! check_email ($from_email) || ! check_email ($email_1) || ! check_email ($email_2) || ! check_email ($email_3))

echo("One of the email addresses you provided was invalid!"); 

Could I make things easy by instead of having... email_1, email_2, and email_3 just name them all to_email?? So then I would just have $from_email and $to_email

Well for starters by requiring the variables $from_email, $email_1, $email_2, and $email_3 to be there, you are then calling your function incorrectly. You'd call it like this:

if (!check_email($from_email,$email_1,$email_2,$email_3)) {
  echo "One of the...";
} 

You could put them in an array but beyond that if you named them the same thing you'd just overwrite the value with each successive form input box.
