Struggling With Email Authorisation Code

With a great deal of thanks from the members of this forum I have been able to put together a registration system. (Yet to go through security processes) However I am struggling to get the email authorisation to work. Does anyone have any feedback or suggestions on how I can get the email code to work?

  if(isset($_POST['loginSubmit']) && $_POST['loginSubmit'] == 'true')
  {
    $loginEmail = filter_var(trim($_POST['email']), FILTER_VALIDATE_EMAIL);
    $loginPassword  = trim($_POST['password']);
     if ($loginEmail === false)
     {
        $errors['loginEmail'] = 'Please enter your email address in a valid format.   Example:

      }
      if(strlen($loginPassword) < 6 || strlen($loginPassword) > 12)
      {
         $errors['loginPassword'] = 'Your password must be between 6-12 characters.';

What errors are being given out?
How do you know it is not working?
Where do you think the problem lies?
What action have you taken to identify the problem?
Did you read “how to ask questions the smart way”?, if you did not, then I suggest you do.

Hi,

No email is sent and there are no error messages.

I had the code working on another registration system however it was poor registation script. I am trying to transfer it to this registration script but the email no longer works.

No idea what so ever where the problem lies to be honest.

Hi,

Does anyone have any suggestions please on what I can try?

Is there anyway I can develop the email section. Is there a standard way to introduce an email authorisation?
