[RESOLVED] using PHP for exceptions?

[Blue1974]

If I could get a little direction on this would appreciate it. I'm trying to understand when data on a form is submitted, where the email is entered twice and you want to verify that the emails match and also that they are actually emails.

I have the code below that should do the exception handling but I'm not sure how to bring the variables in from the contact_form.php. I'm tring to set up the variables in the form as $email1 and $email2? Then do I do an includes on the email_check.php?

email_check.php

<?php
class customException extends Exception
  {
  public function errorMessage()
    {
    //error message
    $errorMsg =
    $this->getMessage().'</b> is not a valid E-Mail address <br />
     <form name="" action="contact_form.php" method="post">
     <input type="button" value="Back" onClick="history.go(-1)">
     </form>';
    return $errorMsg;
    }
  }

include ('contact_form.php');

$email1 = "$_POST[email1]"; //here it should be $_POST[email]
$email2 = "$_POST[email2]";

if ($email1 == $email2){

try
  {
  //check if
  if(filter_var($email, FILTER_VALIDATE_EMAIL) === FALSE)
    {
    //throw exception if email is not valid
    throw new customException($email);
    }
  echo '<"form2mail.php">'; //send to next file or thanks for filling out our form
    }

catch (customException $e)
  {
  //display custom message
  echo $e->errorMessage();
  }
}

else {


?>

contact_form.php

<?php
                  $ContactForm="<div id='content'>
