Validation Errors display NULL?

[Tenaciousmug]

Ok I'm setting the error. I debugged my code and it's catching the phrase in the set_error() function. But it's returning NULL when I try to display it from the display_error() function. These functions are in the form class. I create a new instance of it on the register.php and I'm trying to grab the values. Here is my Form class (only showing the part you need to see):

 

class Form {
    private $error;
    
    public function set_error($errmsg){
        $this->error = $errmsg;
        return;
    }
    public function display_error() {
        $error = "<p style='color:red;'>".$this->error."</p>";
        return $error;
    }
}

 

Then here is my register process:

if(isset($_POST['submit'])) {
    if(isset($_POST['name']) && isset($_POST['username']) && isset($_POST['password']) && isset($_POST['password2']) && isset($_POST['email']) && isset($_POST['email2']) && isset($_POST['dob']) && isset($_POST['gender']) && isset($_POST['security'])) {
        if ($user->register_user($_POST['name'], $_POST['username'], $_POST['password'], $_POST['password2'], $_POST['email'], $_POST['email2'], $_POST['dob'], $_POST['gender'], $_POST['security'])) {
            $message = "User has been registered successfully.";
        }
        else {
            $message = $form->display_error();
        }
    }
    else {
        $message = "Please fill out all parts of the form!";
    }
}

 

It display the $message just fine when I call isset($message), but it won't display it when I assign it the form->display_error() value because it returns NULL.

 

Thank you!
