You should omit the else $_SESSION['validForm'] = true. It overrides any previous attempts at setting the variable to false.
$_SESSION['validForm'] = false declaration should also be changed to true at the start of the file. This declaration is also immediately before the check for $_SESSION['validForm'] == true, so it will never be true.
All validation must occur before any output is sent to the browser, otherwsie you wont be able to redirect the user using header("Location: ..."), because headers will already be sent out.
The short answer is that all of your validation logic should be up at the top of the form, too.
The long answer:
<?php session_start();
require("validationLibrary.php");
$_SESSION['validForm'] = true;
if(isset($_POST['firstName'])){
if(!validateRequired($_POST['firstName'])){
$_SESSION['validForm'] = false;
}
}
if(isset($_POST['lastName'])){
if(!validateRequired($_POST['lastName'])){
$_SESSION['validForm'] = false;
}
}
if(isset($_POST['email'])){
if(!validateEmail($_POST['email'])){
$_SESSION['validForm'] = false;
}
}
if(isset($_POST['age'])){
if(!validateNumber($_POST['age'])){
$_SESSION['validForm'] = false;
}
}
if(isset($_POST['dateOfBirth'])){
if(!validateRequired($_POST['dateOfBirth'])){
$_SESSION['validForm'] = false;
}
}
if($_SESSION['validForm'] == true){
header("Location: registerFormTwo.php");
exit();
}
?>
