Create error if fields don't match

[chrisj]

I have a script with an account_create_page, which requires user name, password, name, address, email address etc.

I wanted the user name to be the email address, so for simplicity I changed the field text for "User Name" to "Email Address" and changed the field text for "Email Address" to "Re-Confirm Email Address".

Is there a way to add code that will get an error if these two fields don't match each other?

thanks

Assume the field names are "email" and "confirm":

$errors = array(); // initialize error message array
$email = trim($_POST['email']);
$confirm = trim($_POST['email']);
if($email !== $confirm)
{
   $errors[] = "Email Address and Confirm Email Address do not match.";
}
// do any other validations in a similar manner, then...
if(count($errors))  // we have one or more errors
{
   echo "<p class='error'>ERROR:";
   foreach($errors as $error)
   {
      echo " $error";
   }
   echo "</p>\n";
}
else
{
   // proceed with form processing
}
