checking if email and confirm email fields are the same using php

Question

I would like to confirm that the email field and confirm email field match each other in my html form before submitting the form to the database, i have done the following but it doesn't seem to work:

<?php

if (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$_SESSION['error'][] = "Invalid email address";
}
    
if ($_POST['email'] != $_POST['confirmemail']) {
$_SESSION['error'][] = "Email addresses do not match";
}
          
else { 

this is followed by the script to submit the form to the database which works fine. Any suggestions would be welcome, many thanks

Answer 1

There might be whitespace issue causing your comparison to fail. try trimming your inputs before comparison.

$email = trim( $_POST['email'] );
$confirmEmail = trim( $_POST['confirmemail'] );

if ($emsil != $confirmEmail ) {
   $_SESSION['error'][] = "Email addresses do not match";
}
